Axcelerator Family FPGAs

v2.8 1-1

General Description

Axcelerator offers high performance at densities of up to

two million equivalent system gates. Based upon the

Actel AX architecture, Axcelerator has several system-

level features such as embedded SRAM (with complete

FIFO control logic), PLLs, segmentable clocks, chip-wide

highway routing, and carry logic.

Device Architecture

Actel's AX architecture, derived from the highly-

successful SX-A sea-of-modules architecture, has been

designed for high performance and total logic module

utilization (Figure 1-1). Unlike in traditional FPGAs, the

entire floor of the Axcelerator device is covered with a

grid of logic modules, with virtually no chip area lost to

interconnect elements or routing.

Programmable Interconnect

Element

The Axcelerator family uses a patented metal-to-metal

antifuse programmable interconnect element that resides

between the upper two layers of metal (Figure 1-2 on

page 1-2). This completely eliminates the channels of

routing and interconnect resources between logic

modules (as implemented on traditional FPGAs) and

enables the efficient sea-of-modules architecture. The

antifuses are normally open circuit and, when

programmed, form a permanent, passive, low-

impedance connection, leading to the fastest signal

propagation in the industry. In addition, the extremely

small size of these interconnect elements gives the

Axcelerator family abundant routing resources.

The very nature of Actel's nonvolatile antifuse

technology provides excellent protection against design

pirating and cloning (FuseLock technology). Cloning is

impossible (even if the security fuse is left

unprogrammed) as no bitstream or programming file is

ever downloaded or stored in the device. Reverse

engineering is virtually impossible due to the difficulty of

trying to distinguish between programmed and

unprogrammed antifuses and also due to the

programming methodology of antifuse devices (see

"Security" on page 2-90).

Logic Modules

Actel's Axcelerator family provides two types of logic

modules: the register cell (R-cell) and the combinatorial

cell (C-cell). The

can implement more than 4,000 combinatorial functions

of up to five inputs (Figure 1-3 on page 1-3).

The R-cell contains a flip-flop featuring asynchronous

clear, asynchronous preset, and active-low enable control

signals (Figure 1-3 on page 1-3). The R-cell registers

feature programmable clock polarity selectable on a

flexibility (e.g., easy mapping of dual-data-rate functions

into the FPGA) while conserving valuable clock resources.

The clock source for the R-cell can be chosen from the

hardwired clocks, routed clocks, or internal logic.

Two C-cells, a single R-cell, and two Transmit (TX) and two

Receive (RX) routing buffers form a Cluster, while two

Clusters comprise a SuperCluster (Figure 1-4 on page 1-3).

Each SuperCluster also contains an independent Buffer (B)

module, which supports buffer insertion on high-fanout

nets by the place-and-route tool, minimizing system

delays while improving logic utilization.

The logic modules within the SuperCluster are arranged

so that two combinatorial modules are side-by-side,

giving a C–C–R – C–C–R pattern to the SuperCluster. This

C–C–R pattern enables efficient implementation

(minimum delay) of two-bit carry logic for improved

arithmetic performance (Figure 1-5 on page 1-3).

The AX architecture is fully fracturable, meaning that if

one or more of the logic modules in a SuperCluster are

used by a particular signal path, the other logic modules

are still available for use by other paths.

At the chip level, SuperClusters are organized into core

tiles, which are arrayed to build up the full chip. For

example, the AX1000 is composed of a 3x3 array of nine

core tiles. Surrounding the array of core tiles are blocks

of I/O Clusters and the I/O bank ring (Table 1-1 on

page 1-3). Each core tile consists of an array of 336

SuperClusters and four SRAM blocks (176 SuperClusters

and three SRAM blocks for the AX250). The SRAM blocks

are arranged in a column on the west side of the tile

(Figure 1-6 on page 1-4).

Embedded Memory

As mentioned earlier, each core tile has either three (in a

smaller tile) or four (in the regular tile) embedded SRAM

blocks along the west side, and each variable-aspect-

ratio SRAM block is 4,608 bits in size. Available memory

configurations are: 128x36, 256x18, 512x9, 1kx4, 2kx2 or

4kx1 bits. The individual blocks have separate read and

write ports that can be configured with different bit

widths on each port. For example, data can be written in

by eight and read out by one.

In addition, every SRAM block has an embedded FIFO

control unit. The control unit allows the SRAM block to

be configured as a synchronous FIFO without using core

logic modules. The FIFO width and depth are

programmable. The FIFO also features programmable

ALMOST-EMPTY (AEMPTY) and ALMOST-FULL (AFULL)

flags in addition to the normal EMPTY and FULL flags. In

addition to the flag logic, the embedded FIFO control

unit also contains the counters necessary for the

generation of the read and write address pointers as well

as control circuitry to prevent metastability and

erroneous operation. The embedded SRAM/FIFO blocks

can be cascaded to create larger configurations.

I/O Logic

The Axcelerator family of FPGAs features a flexible I/O

structure, supporting a range of mixed voltages with its

bank-selectable I/Os: 1.5V, 1.8V, 2.5V, and 3.3V. In all,

Axcelerator FPGAs support at least 14 different I/O

standards (single-ended, differential, voltage-referenced).

The I/Os are organized into banks, with eight banks per

device (two per side). The configuration of these banks

determines the I/O standards supported (see "User I/Os"

on page 2-10 for more information). All I/O standards are

available in each bank.

Each I/O module has an input register (InReg), an output

(Figure 1-7 on page 1-5). An I/O Cluster includes two I/O

modules, four RX modules, two TX modules, and a buffer

(B) module.

Routing

The AX hierarchical routing structure ties the logic

modules, the embedded memory blocks, and the I/O

modules together (Figure 1-8 on page 1-6). At the lowest

level, in and between SuperClusters, there are three local

routing structures: FastConnect, DirectConnect, and

CarryConnect routing. DirectConnects provide the highest

performance routing inside the SuperClusters by

connecting a C-cell to the adjacent R-cell. DirectConnects

do not require an antifuse to make the connection and

achieve a signal propagation time of less than 0.1 ns.

FastConnects provide high-performance, horizontal

routing inside the SuperCluster and vertical routing to

the SuperCluster immediately below it. Only one

programmable connection is used in a FastConnect path,

delivering a maximum routing delay of 0.4 ns.

CarryConnects are used for routing carry logic between

adjacent SuperClusters. They connect the FCO output of

one two-bit, C-cell carry logic to the FCI input of the two-

bit, C-cell carry logic of the SuperCluster below it.

CarryConnects do not require an antifuse to make the

connection and achieve a signal propagation time of less

than 0.1 ns.

The next level contains the core tile routing. Over the

SuperClusters within a core tile, both vertical and

horizontal tracks run across rows or columns,

respectively. At the chip level, vertical and horizontal

tracks extend across the full length of the device, both

north-to-south and east-to-west. These tracks are

composed of highway routing that extend the entire

length of the device (segmented at core tile boundaries)

as well as segmented routing of varying lengths.

Global Resources

Each family member has three types of global signals

available to the designer: HCLK, CLK, and GCLR/GPSET.

There are four hardwired clocks (HCLK) per device that

can directly drive the clock input of each R-cell. Each of

the four routed clocks (CLK) can drive the clock, clear,

preset, or enable pin of an R-cell or any input of a C-cell

(Figure 1-3 on page 1-3).

Global clear (GCLR) and global preset (GPSET) drive the

clear and preset inputs of each R-cell as well as each I/O

Each HCLK and CLK has an associated analog PLL (a total

of eight per chip). Each embedded PLL can be used for

clock delay minimization, clock delay adjustment, or

clock frequency synthesis. The PLL is capable of

operating with input frequencies ranging from 14 MHz

to 200 MHz and can generate output frequencies

between 20 MHz and 1 GHz. The clock can be either

divided or multiplied by factors ranging from 1 to 64.

Additionally, multiply and divide settings can be used in

any combination as long as the resulting clock frequency

is between 20 MHz and 1 GHz. Adjacent PLLs can be

cascaded to create complex frequency combinations.

The PLL can be used to introduce either a positive or a

negative clock delay of up to 3.75 ns in 250 ps

increments. The reference clock required to drive the PLL

can be derived from three sources: external input pad

(either single-ended or differential), internal logic, or the

output of an adjacent PLL.

Low Power (LP) Mode

The AX architecture was created for high-performance

designs but also includes a low power mode (activated via

the LP pin). When the low power mode is activated, I/O

banks can be disabled (inputs disabled, outputs tristated),

and PLLs can be placed in a power-down mode. All

internal register states are maintained in this mode.

Furthermore, individual I/O banks can be configured to

opt out of the LP mode, thereby giving the designer access

to critical signals while the rest of the chip is in low power

mode.

The power can be further reduced by providing an

external voltage source (VPUMP) to the device to bypass

the internal charge pump (See "Low Power Mode" on

page 2-89 for more information).

With the Designer software, a user can lock the design

pins before layout while minimally impacting the results

of place-and-route. Additionally, Actel’s back-annotation

flow is compatible with all the major simulators and the

simulation results can be cross-probed with Silicon

Explorer II, Actel’s integrated verification and logic

analysis tool. Another tool included in the Designer

software is the SmartGen core generator, which easily

creates popular and commonly used logic functions for

implementation into your schematic or HDL design.

Actel's Designer software is compatible with the most

popular FPGA design entry and verification tools from

EDA vendors, such as Mentor Graphics, Synplicity,

Synopsys, and Cadence Design Systems. The Designer

software is available for both the Windows and UNIX

operating systems.

Programming

Programming support is provided through Actel's Silicon

Sculptor II, a single-site programmer driven via a PC-

based GUI. In addition, BP Microsystems offers multi-site

programmers that provide qualified support for Actel

devices. Factory programming is available for high-

volume production needs.

In-System Diagnostic and Debug

Capabilities

The Axcelerator family of FPGAs includes internal probe

circuitry, allowing the designer to dynamically observe

and analyze any signal inside the FPGA without disturbing

normal device operation. Up to four individual signals can

be brought out to dedicated probe pins (PRA/B/C/D) on

the device. The probe circuitry is accessed and controlled

via Silicon Explorer II (Figure 1-9), Actel's integrated

verification and logic analysis tool that attaches to the

serial port of a PC and communicates with the FPGA via

the JTAG port (See "Silicon Explorer II Probe Interface"

on page 2-91).

Summary

Actel’s Axcelerator family of FPGAs extends the

successful SX-A architecture, adding embedded RAM/

FIFOs, PLLs, and high-speed I/Os. With the support of a

suite of robust software tools, design engineers can

incorporate high gate counts and fixed pins into an

Axcelerator design yet still achieve high performance

and efficient device utilization.

Detailed Specifications

Operating Conditions

Table 2-1 lists the absolute maximum ratings of Axcelerator devices. Stresses beyond the ratings may cause permanent

damage to the device. Exposure to Absolute Maximum rated conditions for extended periods may affect device

reliability. Devices should not be operated outside the recommendations in Table 2-2.

Power-Up/Down Sequence

All Axcelerator I/Os are tristated during power-up until normal device operating conditions are reached, when I/Os

enter user mode. VCCDA should be powered up before (or coincidentally with) VCCA and VCCI to ensure the behavior of

user I/Os at system start-up. Conversely, VCCDA should be powered down after (or coincidentally with) VCCA and VCCI.

Note that VCCI and VCCA can be powered up in any sequence with respect to each other, provided the requirement

with respect to VCCDA is satisfied.

Power Estimation Example

This example employs an AX1000 shift-register design with 1,080 R-cells, one C-cell, one reset input, and one LVTTL

12mA Output, with High Slew.

This design uses one HCLK at 100 MHz.

ms = 1,080 (in a shift register - 100% of R-cells are toggling at each clock cycle)

Fs = 100 MHz

s = 1080

=> PHCLK = (P1 + P2 * s + P3 * sqrt[s]) * Fs = 79 mW

and Fs = 100 MHz

=> PR-cells = P7 * ms * Fs = 173 mW

mc = 1 (1 C-cell in this shift-register)

and Fs = 100 MHz

=> PC-cells = P8 * mc * Fs = 0.14 mW

Fpi ~ 0 MHz

and pi= 1 (1 reset input => this is why Fpi=0)

=> Pinputs = P9 * pi * Fpi = 0 mW

Fpo = 50 MHz

and po = 1

=> Poutputs = PI/O * po * Fpo= 27.10 mW

No RAM/FIFO in this shift-register

=> Pmemory = 0 mW

No PLL in this shift-register

=> PPLL = 0 mW

Pac = PHCLK + PCLK + PR-cells + PC-cells + Pinputs + Poutputs + Pmemory + PPLL = 276 mW

Pdc = 7.5mA * 1.5V = 11.25 mW

Ptotal = Pdc + Pac = 11.25 mW + 276mW = 290.30 mW

Thermal Characteristics

Introduction

The temperature variable in Actel’s Designer software refers to the junction temperature, not the ambient

temperature. This is an important distinction because dynamic and static power consumption cause the chip junction

temperature to be higher than the ambient temperature. EQ 2-1 can be used to calculate junction temperature.

TJ = Junction Temperature = ΔT + Ta

EQ 2-1

Where:

ΔT = θja * P

EQ 2-2

Where:

Package Thermal Characteristics

The device junction-to-case thermal characteristic is θjc, and the junction-to-ambient air characteristic is θja. The

thermal characteristics for θja are shown with two different air flow rates. θjc values are provided for reference. The

absolute maximum junction temperature is 125°C.

The maximum power dissipation allowed for commercial- and industrial-grade devices is a function of θja. A sample

calculation of the absolute maximum power dissipation allowed for an 896-pin FBGA package at commercial

temperature and still air is as follows:

The maximum power dissipation allowed for Military temperature and Mil-Std 883B devices is specified as a function

of θjc.

Timing Characteristics

Axcelerator devices are manufactured in a CMOS process, therefore, device performance varies according to

temperature, voltage, and process variations. Minimum timing parameters reflect maximum operating voltage,

minimum operating temperature, and best-case processing. Maximum timing parameters reflect minimum operating

voltage, maximum operating temperature, and worst-case processing. The derating factors shown in Table 2-7 should

be applied to all timing data contained within this datasheet.

All timing numbers listed in this datasheet represent sample timing characteristics of Axcelerator devices. Actual

timing delay values are design-specific and can be derived from the Timer tool in Actel’s Designer software after place-

and-route.

I/O Specifications

Pin Descriptions

Supply Pins

GND Ground

Low supply voltage.

VCCA Supply Voltage

Supply voltage for array (1.5V). See "Operating

Conditions" on page 2-1 for more information.

VCCIBx Supply Voltage

Supply voltage for I/Os. Bx is the I/O Bank ID – 0 to 7. See

"Operating Conditions" on page 2-1 for more

information.

VCCDA Supply Voltage

Supply voltage for the I/O differential amplifier and JTAG

and probe interfaces. See "Operating Conditions" on

page 2-1 for more information. VCCDA should be tied to

3.3V.

VCCPLA/B/C/D/E/F/G/H Supply Voltage

PLL analog power supply (1.5V) for internal PLL. There

are eight in each device. VCCPLA supports the PLL

associated with global resource HCLKA, VCCPLB supports

the PLL associated with global resource HCLKB, etc. The

PLL analog power supply pins should be connected to

1.5V whether PLL is used or not.

VCOMPLA/B/C/D/E/F/G/HSupply Voltage

Compensation reference signals for internal PLL. There

are eight in each device. VCOMPLA supports the PLL

associated with global resource HCLKA, VCOMPLE

supports the PLL associated with global resource CLKE,

etc. (see Figure 2-2 on page 2-9 for correct external

connection to the supply). The VCOMPLX pins should be

left floating if PLL is not used.

VPUMP Supply Voltage (External Pump)

In the low power mode, VPUMP will be used to access an

external charge pump (if the user desires to bypass the

internal charge pump to further reduce power). The

device starts using the external charge pump when the

voltage level on VPUMP reaches VIH1. In normal device

operation, when using the internal charge pump, VPUMP

should be tied to GND.

User-Defined Supply Pins

VREF Supply Voltage

Reference voltage for I/O banks. VREF pins are configured

by the user from regular I/O pins; VREF pins are not in

fixed locations. There can be one or more VREF pins in an

I/O bank.

Global Pins

HCLKA/B/C/D Dedicated (Hardwired) Clocks A, B, C

and D

These pins are the clock inputs for sequential modules or

north PLLs. Input levels are compatible with all

supported I/O standards. There is a P/N pin pair for

support of differential I/O standards. Single-ended clock

I/Os can only be assigned to the P side of a paired I/O.

This input is directly wired to each R-cell and offers clock

speeds independent of the number of R-cells being

These pins are clock inputs for clock distribution

networks or south PLLs. Input levels are compatible with

all supported I/O standards. There is a P/N pin pair for

support of differential I/O standards. Single-ended clock

I/Os can only be assigned to the P side of a paired I/O.

The clock input is buffered prior to clocking the R-cells.

When the CLK pins are unused, Actel recommends that

they are tied to ground.

JTAG/Probe Pins

PRA/B/C/D Probe A/B/C/D

The Probe pins are used to output data from any user-

defined design node within the device (controlled with

Silicon Explorer II). These independent diagnostic pins

can be used to allow real-time diagnostic output of any

signal path within the device. The pins’ probe

capabilities can be permanently disabled to protect

programmed design confidentiality. The probe pins are

of LVTTL output levels.

TCK Test Clock

Test clock input for JTAG boundary-scan testing and

diagnostic probe (Silicon Explorer II).

TDI Test Data Input

Serial input for JTAG boundary-scan testing and

diagnostic probe. TDI is equipped with an internal 10 kΩ

pull-up resistor.

TDO Test Data Output

Serial output for JTAG boundary-scan testing.

TMS Test Mode Select

The TMS pin controls the use of the IEEE 1149.1

boundary-scan pins (TCK, TDI, TDO, TRST). TMS is

equipped with an internal 10 kΩ pull-up resistor.

TRST Boundary Scan Reset Pin

The TRST pin functions as an active-low input to

asynchronously initialize or reset the boundary scan circuit.

The TRST pin is equipped with a 10 kΩ pull-up resistor.

Special Functions

LP Low Power Pin

The LP pin controls the low power mode of Axcelerator

devices. The device is placed in the low power mode by

connecting the LP pin to logic high. To exit the low

power mode, the LP pin must be set Low. Additionally,

the LP pin must be set Low during chip powering-up or

chip powering-down operations. See "Low Power

Mode" on page 2-89 for more details.

NC No Connection

This pin is not connected to circuitry within the device.

These pins can be driven to any voltage or can be left

floating with no effect on the operation of the device.

User I/Os2

Introduction

The Axcelerator family features a flexible I/O structure,

supporting a range of mixed voltages (1.5V, 1.8V, 2.5V,

and 3.3V) with its bank-selectable I/Os. Table 2-8 on

page 2-11 contains the I/O standards supported by the

Axcelerator family, and Table 2-10 on page 2-11

compares the features of the different I/O standards.

Each I/O provides programmable slew rates, drive

strengths, and weak pull-up and weak pull-down circuits.

I/O standards, except 3.3V PCI and 3.3V PCI-X, are

capable of hot insertion. 3.3V PCI and 3.3V PCI-X are 5V

tolerant with the aid of an external resistor.

The input buffer has an optional user-configurable delay

element. The element can reduce or eliminate the hold

time requirement for input signals registered within the

I/O cell. The value for the delay is set on a bank-wide

basis. Note that the delay WILL be a function of process

variations as well as temperature and voltage changes.

Each I/O includes three registers: an input (InReg), an

output (OutReg), and an enable register (EnReg). I/Os are

organized into banks, and there are eight banks per

device — two per side (Figure 2-6 on page 2-15). Each I/O

bank has a common VCCI, the supply voltage for its I/Os.

For voltage-referenced I/Os, each bank also has a

common reference-voltage bus, VREF

. While VREF must

have a common voltage for an entire I/O bank, its

location is user-selectable. In other words, any user I/O in

the bank can be selected to be a VREF

The location of the VREF pin should be selected according

to the following rules:

• Any pin that is assigned as a VREF can control a

maximum of eight user I/O pad locations in each

direction (16 total maximum) within the same I/O

bank.

• I/O pad locations listed as no connects are counted

as part of the 16 maximum. In many cases, this

leads to fewer than eight user I/O package pins in

each direction being controlled by a VREF pin.

• Dedicated I/O pins (GND, VCCI...) are counted as

part of the 16.

• The two user I/O pads immediately adjacent on each

side of the VREF pin (four in total) may only be used

as an input. The exception is when there is a VCCI/

GND pair separating the VREF pin and the user I/O

pad location.

2. Do not use an external resister to pull the I/O above VCCI for a higher logic “1” voltage level. The desired higher logic “1”

voltage level will be degraded due to a small I/O current, which exists when the I/O is pulled up above VCCI.

Axcelerator Family FPGAs

v2.8 2-11

The differential amplifier supply voltage VCCDA should be

connected to 3.3V.

A user can gain access to the various I/O standards in

three ways:

• Instantiate specific library macros that represent

the desired specific standard

• Use generic I/O macros and then use Actel

Designer’s PinEditor to specify the desired I/O

standards (please note that this is not applicable

to differential standards)

• A combination of the first two methods.

Please refer to the I/O Features in Axcelerator Family

2-12 v2.8

5V Tolerance

There are two schemes to achieve 5V tolerance:

1. 3.3V PCI and 3.3V PCI-X are the only I/O standards

that directly allow 5V tolerance. To implement this,

an internal clamp diode between the input pad and

the VCCI pad is enabled so that the voltage at the

input pin is clamped as shown in EQ 2-3:

Vinput = VCCI + Vdiode = 3.3V + 0.8V = 4.1V

EQ 2-3

An external series resister (~100Ω) is required between

the input pin and the 5V signal source to limit the

current (Figure 2-3).

2. 5V tolerance can also be achieved with 3.3V I/O

standards (3.3V PCI, 3.3V PCI-X, and LVTTL) using a

bus-switch product (e.g. IDTQS32X2384). This will

convert the 5V signal to a 3.3V signal with minimum

delay (Figure 2-4).

Simultaneous Switching Outputs (SSO)

When multiple output drivers switch simultaneously,

they induce a voltage drop in the chip/package power

distribution. This simultaneous switching momentarily

raises the ground voltage within the device relative to

the system ground. This apparent shift in the ground

potential to a non-zero value is known as simultaneous

switching noise (SSN) or more commonly, ground

bounce.

SSN becomes more of an issue in high pin count

packages and when using high performance devices such

as the Axcelerator family. Based upon testing, Actel

recommends that users not exceed eight simultaneous

switching outputs (SSO) per each VCCI/GND pair. To ease

this potential burden on designers, Actel has designed all

of the Axcelerator BGAs3 to not exceed this limit with

the exception of the CS180, which has an I/O to VCCI/GND

pair ratio of nine to one.

Please refer to the Simultaneous Switching Noise and

Signal Integrity application note for more information.

I/O Banks and Compatibility

Since each I/O bank has its own user-assigned input

reference voltage (VREF) and an input/output supply

voltage (VCCI), only I/Os with compatible standards can

be assigned to the same bank.

Table 2-11 shows the compatible I/O standards for a

common VREF (for voltage-referenced standards).

Similarly, Table 2-12 shows compatible standards for a

common VCCI.

Table 2-13 on page 2-13 summarizes the different

combinations of voltages and I/O standards that can be

used together in the same I/O bank. Note that two I/O

standards are compatible if:

• Their VCCI values are identical.

• Their VREF standards are identical (if applicable).

For example, if LVTTL 3.3V (VREF= 1.0V) is used, then the

other available (i.e. compatible) I/O standards in the

same bank are LVTTL 3.3V PCI/PCI-X, GTL+, and LVPECL.

Also note that when multiple I/O standards are used

within a bank, the voltage tolerance will be limited to

the minimum tolerance of all I/O standards used in the

bank.

Axcelerator Family FPGAs

2-14 v2.8

I/O Clusters

Each I/O cluster incorporates two I/O modules, four RX

modules and two TX modules, and a buffer module. In

turn, each I/O module contains one Input Register

(InReg), one Output Register (OutReg), and one Enable

Using an I/O Register

To access the I/O registers, registers must be instantiated

in the netlist and then connected to the I/Os. Usage of

each I/O register (register combining) is individually

controlled and can be selected/deselected using the

PinEditor tool in Actel's Designer software. I/O register

combining can also be controlled at the device level,

affecting all I/Os. Please note, the I/O register option is

deselected by default in any given design.4

In addition, Designer software provides a global option to

enable/disable the usage of registers in the I/Os. This option

is design-specific. The setting for each individual I/O

overrides this global option. Furthermore, the global set

fuse option in the Designer software, when checked, causes

all I/O registers to output logic High at device power-up.

Using the Weak Pull-Up and Pull-Down

Circuits

Each Axcelerator I/O comes with a weak pull-up/down

circuit (on the order of 10 kΩ). I/O macros are provided

for combinations of pull up/down for LVTTL, LVCMOS

(2.5V, 1.8V, and 1.5V) standards. These macros can be

instantiated if a keeper circuit for any input buffer is

required.

Customizing the I/O

• A five-bit programmable input delay element is

associated with each I/O. The value of this delay is

set on a bank-wide basis (Table 2-14 on page 2-15).

It is optional for each input buffer within the bank

(i.e. the user can enable or disable the delay

element for the I/O). When the input buffer drives a

activated by default to ensure a zero hold-time.

The default setting for this property can be set in

Designer. When the input buffer does not drive a

provide higher performance. Again, this can be

overridden by changing the default setting for this

property in Designer.

• The slew-rate value for the LVTTL output buffer

can be programmed and can be set to either slow

or fast.

• The drive strength value for LVTTL output buffers

can be programmed as well. There are four

different drive strength values – 8mA, 12mA,

16mA, or 24mA – that can be specified in

Designer.5

Using the Differential I/O Standards

Differential I/O macros should be instantiated in the

netlist. The settings for these I/O standards cannot be

changed inside Designer. Please note that there are no

tristated or bidirectional I/O buffers for differential

standards.

Using the Voltage-Referenced I/O Standards

Using these I/O standards is similar to that of single-

ended I/O standards. Their settings can be changed in

Designer.

Using DDR (Double Data Rate)

In Double Data Rate mode, new data is present on every

transition of the clock signal. Clock and data lines have

identical bandwidth and signal integrity requirements,

making it very efficient for implementing very high-

speed systems.

To implement a DDR, users need to:

1. Instantiate an input buffer (with the required I/O

standard)

2. Instantiate the DDR_REG macro (Figure 2-6)

3. Connect the output from the Input buffer to the

input of the DDR macro

Macros for Specific I/O Standards

There are different macro types for any I/O standard or

feature that determine the required VCCI and VREF

voltages for an I/O. The generic buffer macros require

the LVTTL standard with slow slew rate and 24mA-drive

strength. LVTTL can support high slew rate but this

should only be used for critical signals.

Most of the macro symbols represent variations of the six

generic symbol types:

• CLKBUF: Clock Buffer

• HCLKBUF: Hardwired Clock Buffer

• INBUF: Input Buffer

• OUTBUF: Output Buffer

• TRIBUF: Tristate Buffer

• BIBUF: Bidirectional Buffer

Other macros include the following:

• Differential I/O standard macros: The LVDS and

LVPECL macros either have a pair of differential

inputs (e.g. INBUF_LVDS) or a pair of differential

outputs (e.g. OUTBUF_LVPECL).

• Pull-up and pull-down variations of the INBUF,

BIBUF, and TRIBUF macros. These are available

only with TTL and LVCMOS thresholds. They can

be used to model the behavior of the pull-up and

pull-down resistors available in the architecture.

Whenever an input pin is left unconnected, the

output pin will either go high or low rather than

unknown. This allows users to leave inputs

unconnected without having the negative effect

on simulation of propagating unknowns.

• DDR_REG macro. It can be connected to any I/O

standard input buffers (i.e. INBUF) to implement a

double data rate register. Designer software will

map it to the I/O module in the same way it maps

the other registers to the I/O module.

first I/O bank (IOB NE). IO12PB1 combined

with IO12NB1 form a differential pair.

For those I/Os that can be employed

either as a user I/O or as a special

function, the following nomenclature

is used:

IOxxXBxFx/special_function_name

IOxxPB1Fx/xCLKx this pin can be configured as a clock

input or as a user I/O.

Differential Standards

Physical Implementation

Implementing differential I/O standards requires the

configuration of a pair of external I/O pads, resulting in a

single internal signal. To facilitate construction of the

differential pair, a single I/O Cluster contains the

resources for a pair of I/Os. Configuration of the I/O

Cluster as a differential pair is handled by Actel's

Designer software when the user instantiates a

differential I/O macro in the design.

Differential I/Os can also be used in conjunction with the

embedded Input Register (InReg), Output Register

(OutReg), Enable Register (EnReg), and Double Data

Rate (DDR). However, there is no support for

bidirectional I/Os or tristates with these standards.

LVDS

Low-Voltage Differential Signal (ANSI/TIA/EIA-644) is a

high-speed, differential I/O standard. It requires that one

data bit is carried through two signal lines, so two pins

are needed. It also requires an external resistor

termination. The voltage swing between these two

signal lines is approximately 350 mV.

The LVDS circuit consists of a differential driver

connected to a terminated receiver through a constant-

impedance transmission line. The receiver is a wide-

common-mode-range differential amplifier. The

common-mode range is from 0.2V to 2.2V for a

differential input with 400 mV swing.

To implement the driver for the LVDS circuit, drivers from

two adjacent I/O cells are used to generate the

differential signals (note that the driver is not a current-

mode driver). This driver provides a nominal constant

current of 3.5 mA. When this current flows through a

100 Ω termination resistor on the receiver side, a voltage

swing of 350 mV is developed across the resistor. The

direction of the current flow is controlled by the data fed

to the driver.

An external-resistor network (three resistors) is needed

to reduce the voltage swing to about 350 mV. Therefore,

four external resistors are required, three for the driver

and one for the receiver.

LVPECL

Low-Voltage Positive Emitter-Coupled Logic (LVPECL) is another differential I/O standard. It requires that one data bit

is carried through two signal lines. Like LVDS, two pins are needed. It also requires external resistor termination. The

voltage swing between these two signal lines is approximately 850 mV.

The LVPECL circuit is similar to the LVDS scheme. It requires four external resistors, three for the driver and one for the

receiver. The values for the three driver resistors are different from that of LVDS since the output voltage levels are

different. Please note that the VOH levels are 200 mV below the standard LVPECL levels.

C-Cell

Introduction

The C-cell is one of the two logic module types in the AX

architecture. It is the combinatorial logic resource in the

Axcelerator device. The AX architecture implements a

new combinatorial cell that is an extension of the C-cell

implemented in the SX-A family. The main enhancement

of the new C-cell is the addition of carry-chain logic.

The C-cell can be used in a carry-chain mode to construct

arithmetic functions. If carry-chain logic is not required,

it can be disabled.

The C-cell features the following (Figure 2-27):

• Eight-input MUX (data: D0-D3, select: A0, A1, B0,

B1). User signals can be routed to any one of these

inputs. Any of the C-cell inputs (D0-D3, A0, A1, B0,

B1) can be tied to one of the four routed clocks

(CLKE/F/G/H).

• Inverter (DB input) can be used to drive a

complement signal of any of the inputs to the C-

cell.

• A carry input and a carry output. The carry input

signal of the C-cell is the carry output from the C-

cell directly to the north.

• Carry connect for carry-chain logic with a signal

propagation time of less than 0.1 ns.

• A hardwired connection (direct connect) to the

adjacent R-cell (Register Cell) for all C-cells on the

east side of a SuperCluster with a signal

propagation time of less than 0.1 ns.

This layout of the C-cell (and the C-cell Cluster) enables

the implementation of over 4,000 functions of up to five

bits. For example, two C-cells can be used together to

implement a four-input XOR function in a single cell

delay.

The carry-chain configuration is handled automatically

for the user with Actel's extensive macro library (please

see Actel’s Antifuse Macro Library Guide for a complete

listing of available Axcelerator macros).

Carry-Chain Logic

The Axcelerator dedicated carry-chain logic offers a very

compact solution for implementing arithmetic functions

without sacrificing performance.

To implement the carry-chain logic, two C-cells in a

Cluster are connected together so the FCO (i.e. carry out)

for the two bits is generated in a carry look-ahead

scheme to achieve minimum propagation delay from the

FCI (i.e. carry in) into the two-bit Cluster. The two-bit

carry logic is shown in Figure 2-29.

The FCI of one C-cell pair is driven by the FCO of the

C-cell pair immediately above it. Similarly, the FCO of one

C-cell pair, drives the FCI input of the C-cell pair

immediately below it (Figure 1-4 on page 1-3 and

Figure 2-30 on page 2-46).

The carry-chain logic is selected via the CFN input. When

carry logic is not required, this signal is deasserted to

save power. Again, this configuration is handled

automatically for the user through Actel's macro library.

The signal propagation delay between two C-cells in the

carry-chain sequence is 0.1 ns.

R-Cell

Introduction

The R-cell, the sequential logic resource of the

Axcelerator devices, is the second logic module type in

the AX family architecture. It includes clock inputs for all

eight global resources of the Axcelerator architecture as

well as global presets and clears (Figure 2-31).

The main features of the R-cell include the following:

• Direct connection to the adjacent logic module

through the hardwired connection DCIN. DCIN is

driven by the DCOUT of an adjacent C-cell via the

Direct-Connect routing resource, providing a

connection with less than 0.1 ns of routing delay.

• The R-cell can be used as a standalone flip-flop. It

can be driven by any C-cell or I/O modules through

the regular routing structure (using DIN as a

routable data input). This gives the option of

using the R-Cell as a 2:1 MUXed flip-flop as well.

• Provision of data enable-input (S0).

• Independent active-low asynchronous clear (CLR).

• Independent active-low asynchronous preset

(PSET). If both CLR and PSET are low, CLR has

higher priority.

• Clock can be driven by any of the following (CKP

selects clock polarity):

– One of the four high performance hardwired

fast clocks (HCLKs)

– One of the four routed clocks (CLKs)

– User signals

• Global power-on clear (GCLR) and preset (GPSET),

which drive each flip-flop on a chip-wide basis.

– When the Global Set Fuse option in the

Designer software is unchecked (by default),

GCLR = 0 and GPSET =1 at device power-up.

When the option is checked, GCLR = 1 and

GPSET= 0. Both pins are pulled High when the

device is in user mode.

• S0, S1, PSET, and CLR can be driven by routed

clocks CLKE/F/G/H or user signals.

• DIN and S1 can be driven by user signals.

As with the C-cell, the configuration of the R-cell to

perform various functions is handled automatically for

the user through Actel's extensive macro library (please

see Actel’s Antifuse Macro Library Guide for a complete

listing of available AX macros).

Buffer Module

Introduction

An additional resource inside each SuperCluster is the Buffer (B) module (Figure 1-4 on page 1-3). When a fanout

constraint is applied to a design, the synthesis tool inserts buffers as needed. The buffer module has been added to

the AX architecture to avoid logic duplication resulting from the hard fanout constraints. The router utilizes this logic

resource to save area and reduce loading and delays on medium-to-high-fanout nets.

Routing Specifications

Routing Resources

The routing structure found in Axcelerator devices

enables any logic module to be connected to any other

logic module while retaining high performance. There

are multiple paths and routing resources that can be

used to route one logic module to another, both within a

SuperCluster and elsewhere on the chip.

There are four primary types of routing within the AX

architecture: DirectConnect, CarryConnect, FastConnect,

and Vertical and Horizontal Routing.

DirectConnect

DirectConnects provide a high-speed connection

between an R-cell and its adjacent C-cell (Figure 2-35).

This connection can be made from DCOUT of the C-cell

to DCIN of the R-cell by configuring of the S1 line of the

R-cell. This provides a connection that does not require

an antifuse and has a delay of less than 0.1 ns.

CarryConnect

CarryConnects are used to build carry chains for

arithmetic functions (Figure 2-35). The FCO output of the

right C-cell of a two-C-cell Cluster drives the FCI input of

the left C-cell in the two-C-cell Cluster immediately

below it. This pattern continues down both sides of each

SuperCluster column.

Similar to the DirectConnects, CarryConnects can be built

without an antifuse connection. This connection has a

delay of less than 0.1 ns from the FCO of one two-C-cell

cluster to the FCI of the two-C-cell cluster immediately

below it (see the "Carry-Chain Logic" on page 2-45 for

more information).

FastConnect

For high-speed routing of logic signals, FastConnects can

be used to build a short distance connection using a

single antifuse (Figure 2-36 on page 2-51). FastConnects

provide a maximum delay of 0.3 ns. The outputs of each

logic module connect directly to the Output Tracks

within a SuperCluster. Signals on the Output Tracks can

then be routed through a single antifuse connection to

drive the inputs of logic modules either within one

SuperCluster or in the SuperCluster immediately below

it.

Vertical and Horizontal Routing

Vertical and Horizontal Tracks provide both local and

long distance routing (Figure 2-37 on page 2-51). These

tracks are composed of both short-distance, segmented

routing and across-chip routing tracks (segmented at

core tile boundaries). The short-distance, segmented

routing resources can be concatenated through antifuse

connections to build longer routing tracks.

These short-distance routing tracks can be used within

and between SuperClusters or between modules of non-

adjacent SuperClusters. They can be connected to the

Output Tracks and to any logic module input (R-cell,

C-cell, Buffer, and TX module).

The across-chip horizontal and vertical routing provides

long-distance routing resources. These resources

interface with the rest of the routing structures through

Figure 2-35 • DirectConnect and CarryConnect

Axcelerator Family FPGAs

v2.8 2-51

the RX and TX modules (Figure 2-37). The RX module is

used to drive signals from the across-chip horizontal and

vertical routing to the Output Tracks within the

SuperCluster. The TX module is used to drive vertical and

horizontal across-chip routing from either short-distance

horizontal tracks or from Output Tracks. The TX module

can also be used to drive signals from vertical across-chip

tracks to horizontal across-chip tracks and vice versa.

Global Resources

One of the most important aspects of any FPGA

architecture is its global resources or clocks. The

Axcelerator family provides the user with flexible and

easy-to-use global resources, without the limitations

normally found in other FPGA architectures.

The AX architecture contains two types of global

resources, the HCLK (hardwired clock) and CLK (routed

clock). Every Axcelerator device is provided with four

HCLKs and four CLKs for a total of eight clocks,

regardless of device density.

Hardwired Clocks

The hardwired (HCLK) is a low-skew network that can

directly drive the clock inputs of all sequential modules

(R-cells, I/O registers, and embedded RAM/FIFOs) in the

device with no antifuse in the path. All four HCLKs are

available everywhere on the chip.

Routed Clocks

The routed clock (CLK) is a low-skew network that can

drive the clock inputs of all sequential modules in the

device (logically equivalent to the HCLK), but has the

added flexibility in that it can drive the S0 (Enable), S1,

PSET, and CLR input of a register (R-cells and I/O

registers) as well as any of the inputs of any C-cell in the

device. This allows CLKs to be used not only as clocks, but

also for other global signals or high fanout nets. All four

CLKs are available everywhere on the chip.

Global Resource Distribution

At the root of each global resource is a PLL. There are

two groups of four PLLs for every device. One group,

located at the center of the north edge (in the I/O ring)

of the chip, sources the four HCLKs. The second group,

located at the center of the south edge (again in the I/O

ring), sources the four CLKs (Figure 2-38).

Regardless of the type of global resource, HCLK or CLK,

each of the eight resources reach the ClockTileDist (CTD)

Cluster located at the center of every core tile with zero

skew. From the ClockTileDist Cluster, all four HCLKs and

four CLKs are distributed through the core tile (Figure 2-

39).

ClockTileDist Cluster

Axcelerator Family FPGAs

2-60 v2.8

The ClockTileDist Cluster contains an HCLKMux (HM)

module for each of the four HCLK trees and a CLKMux

(CM) module for each of the CLK trees. The HCLK

branches then propagate horizontally through the

middle of the core tile to HCLKColDist (HD) modules in

every SuperCluster column. The CLK branches propagate

vertically through the center of the core tile to

CLKRowDist (RD) modules in every SuperCluster row.

Together, the HCLK and CLK branches provide for a low-

skew global fanout within the core tile (Figure 2-40 and

Figure 2-41).

Figure 2-40 • CTD, CD, and HD Module Layout

Figure 2-41 • HCLK and CLK Distribution within a Core Tile

Axcelerator Family FPGAs

v2.8 2-61

The HM and CM modules can select between:

• The HCLK or CLK source respectively

• A local signal routed on generic routing resources

This allows each core tile to have eight clocks

independent of the other core tiles in the device.

Both HCLK and CLK are segmentable, meaning that

individual branches of the global resource can be used

independently.

Like the HM and CM modules, the HD and RD modules

can select between:

• The HCLK or CLK source from the HM or CM

module respectively

• A local signal routed on generic routing resources

The AX architecture is capable of supporting a large

number of local clocks – 24 segments per HCLK driving

north-south and 28 segments per CLK driving east-west

per core tile.

Actel's Designer software’s place-and-route takes

advantage of the segmented clock structure found in

Axcelerator devices by turning off any unused clock

segments. This results in not only better performance but

also lower power consumption.

Global Resource Access Macros

Global resources can be driven by one of three sources:

external pad(s), an internal net, or the output of a PLL.

These connections can be made by using one of three

types of macros: CLKBUF, CLKINT, and PLLCLK.

CLKBUF and HCLKBUF

CLKBUF (HCLKBUF) is used to drive a CLK (HCLK) from

external pads. These macros can be used either

generically or with the specific I/O standard desired

(e.g. CLKBUF_LVCMOS25, HCLKBUF_LVDS, etc.)

(Figure 2-42).

Package pins CLKEP and CLKEN are associated with

CLKE; package pins HCLKAP and HCLKAN are

associated with HCLKA, etc.

Note that when CLKBUF (HCLKBUF) is used with a

single-ended I/O standard, it must be tied to the P-

pad of the CLK (HCLK) package pin. In this case, the

CLK (HCLK) N-pad can be used for user signals.

CLKINT and HCLKINT

CLKINT (HCLKINT) is used to access the CLK (HCLK)

resource internally from the user signals (Figure 2-43).

PLLRCLK and PLLHCLK

PLLRCLK (PLLHCLK) is used to drive global resource

CLK (HCLK) from a PLL (Figure 2-44).

Using Global Resources with PLLs

Each global resource has an associated PLL at its root. For

example, PLLA can drive HCLKA, PLLE can drive CLKE, etc.

(Figure 2-45 on page 2-62).

In addition, each clock pin of the package can be used to

drive either its associated global resource or PLL. For

example, package pins CLKEP and CLKEN can drive either

the RefCLK input of PLLE or CLKE.

There are two macros required when interfacing the

embedded PLLs with the global resources: PLLINT and PLLOUT.

PLLINT

This macro is used to drive the RefCLK input of the PLL

internally from user signals.

PLLOUT

This macro is used to connect either the CLK1 or CLK2

output of a PLL to the regular routing network (Figure 2-

46 on page 2-62).

output of PLLE is driving logic (via PLLOUT). In turn, this logic is driving the global resource CLKE. PLLF is driving both

CLKF and CLKG global resources.

Axcelerator Clock Management System

Introduction

Each member of the Axcelerator family6 contains eight

phase-locked loop (PLL) blocks which perform the

following functions:

• Programmable Delay (32 steps of 250 ps)

• Clock Skew Minimization

• Clock Frequency Synthesis

Each PLL has the following key features:

• Input Frequency Range – 14 to 200 MHz

• Output Frequency Range – 20 MHz to 1 GHz

• Output Duty Cycle Range – 45% to 55%

• Maximum Long-Term Jitter – 1% or 100ps

(whichever is greater)

• Maximum Short-Term Jitter – 50ps + 1% of Output

Frequency

• Maximum Acquisition Time (lock) – 20µs

Physical Implementation

The eight PLL blocks are arranged in two groups of four.

One group is located in the center of the northern edge

of the chip, while the second group is centered on the

southern edge. The northern group is associated with

the four HCLK networks (e.g. PLLA can drive HCLKA),

while the southern group is associated with the four CLK

networks (e.g. PLLE can drive CLKE).

Each PLL cell is connected to two I/O pads and a PLL

Cluster that interfaces with the FPGA core. Figure 2-48

illustrates a PLL block. The VCCPLL pin should be

connected to a 1.5V power supply through a 250 Ω

resistor. Furthermore, 0.1 μF and 10 μF decoupling

capacitors should be connected across the VCCPLL and

VCOMPPLL pins. Note: The VCOMPPLL pin should never be

grounded (Figure 2-2 on page 2-9)!

The I/O pads associated with the PLL can also be

configured for regular I/O functions except when it is

used as a clock buffer. The I/O pads can be configured in

all the modes available to the regular I/O pads in the

same I/O bank. In particular, the [H]CLKxP pad can be

configured as a differential pair, single-ended, or

voltage-referenced standard. The [H]CLKxN pad can only

be used as a differential pair with [H]CLKxP.

The block marked “/i Delay Match” is a fixed delay equal

to that of the i divider. The “/j Delay Match” block has

the same function as its j divider counterpart.

6. AX2000-CQ256 does not support operation of the phase-locked loops. This is in order to support full pin compatibility with

RTAX2000S/SL-CQ256.

Functional Description

Figure 2-48 on page 2-63 illustrates a block diagram of

the PLL. The PLL contains two dividers, i and j, that allow

frequency scaling of the clock signal:

• The i divider in the feedback path allows

multiplication of the input clock by integer factors

ranging from 1 to 64, and the resultant frequency

is available at the output of the PLL block.

• The j divider divides the PLL output by integer

factors ranging from 1 to 64, and the divided clock

is available at CLK1.

• The two dividers together can implement any

combination of multiplication and division up to a

maximum frequency of 1 GHz on CLK1. Both the

CLK1 and CLK2 outputs have a fixed 50/50 duty

cycle.

• The output frequencies of the two clocks are given

by the following formulas (fREF is the reference

clock frequency):

fCLK1 = fREF * (DividerI) / (DividerJ)

EQ 2-4

fCLK2 = fREF * (DividerI)

EQ 2-5

• CLK2 provides the PLL output directly—without

division

The input and output frequency ranges are selected by

LowFreq and Osc(2:0), respectively. These functions and

their possible values are detailed in Table 2-79.

The delay lines shown in Figure 2-48 on page 2-63 are

programmable. The feedback clock path can be delayed

(using the five DelayLine bits) relative to the reference

clock (or vice versa) by up to 3.75 ns in increments of

250 ps. Table 2-79 describes the usage of these bits. The

delay increments are independent of frequency, so this

results in phase changes that vary with frequency. The

delay value is highly dependent on VCC and the speed

grade.

Figure 2-49 on page 2-65 is a logical diagram of the

various control signals to the PLL and shows how the PLL

interfaces with the global and routing networks of the

FPGA. Note that not all signals are user-accessible. These

non-user-accessible signals are used by Actel's place-and-

route tool to control the configuration of the PLL. The

user gains access to these control signals either based

upon the connections built in the user's design or

through the special macros (Table 2-83 on page 2-67)

inserted into the design. For example, connecting the

macro PLLOUT to CLK2 will control the OUTSEL signal.

CLK1 and CLK2

Both PLL outputs, CLK1 and CLK2, can be used to drive a

global resource, an adjacent PLL RefCLK input, or a net in

the FPGA core. Not all drive combinations are possible

(Table 2-80).

Restrictions on CLK1 and CLK2

• When both are driving global resources, they must

be driving the same type of global resource (i.e.

either HCLK or CLK).

• Only one can drive a routed net at any given time.

Table 2-81 and Table 2-82 specify all the possible CLK1

and CLK2 connections for the north and south PLLs.

HCLK1 and HCLK2 are used to denote the different HCLK

networks when two are being driven at the same time by

a single PLL (Note that HCLK1 is the primary clock

resource associated with the PLL, and HCLK2 is the clock

resource associated with the adjacent PLL). Likewise,

CLK1 and CLK2 are used to denote the different CLK

networks when two are being driven at the same time by

a single PLL (Figure 2-48 on page 2-63).

User Flow

There are two methods of including a PLL in a design:

• The recommended method of using a PLL is to

create custom PLL blocks using Actel's macro

generator, SmartGen, that can be instantiated in a

design.

• The alternative method is to instantiate one of the

generic library primitives (PLL or PLLFB) into either

a schematic or HDL netlist, using inverters for

polarity control and tying all unused address and

data bits to ground.

Frequency Synthesis

Figure 2-53 illustrates an example where the PLL is used

to multiply a 155.5 MHz external clock up to 622 MHz.

Note that the same PLL schematic could use an external

350 MHz clock, which is divided down to 155 MHz by the

FPGA internal logic.

Figure 2-54 illustrates the PLL using both dividers to

synthesize a 133 MHz output clock from a 155 MHz input

reference clock. The input frequency of 155 MHz is

multiplied by 6 and divided by 7, giving a CLK1 output

frequency of 132.86 MHz. When dividers are used, a

given ratio can be generated in multiple ways, allowing

the user to stay within the operating frequency ranges of

the PLL.

Clock Skew Minimization

Figure 2-56 indicates how feedback from the clock network can be used to create minimal skew between the distributed

clock network and the input clock. The input clock is fed to the reference clock input of the PLL. The output clock (CLK2)

feeds a routed clock network. The feedback input to the PLL uses a clock input delayed by a routing network. The PLL then

adjusts the phase of the input clock to match the delayed clock, thus providing nearly zero effective skew between the two

clocks. Refer to Actel’s Axcelerator Family PLL and Clock Management application note for more information.

Embedded Memory

The AX architecture provides extensive, high-speed

memory resources to the user. Each 4,608 bit block of

RAM contains its own embedded FIFO controller,

allowing the user to configure each block as either RAM

or FIFO.

To meet the needs of high performance designs, the

memory blocks operate in synchronous mode for both

read and write operations. However, the read and write

clocks are completely independent, and each may

operate up to and above 500 MHz.

No additional core logic resources are required to

cascade the address and data buses when cascading

different RAM blocks. Dedicated routing runs along each

column of RAM to facilitate cascading.

The AX memory block includes dedicated FIFO control

logic to generate internal addresses and external flag

logic (FULL, EMPTY, AFULL, AEMPTY). Since read and

write operations can occur asynchronously to one

another, special control circuitry is included to prevent

metastability, overflow, and underflow. A block diagram

of the memory module is illustrated in Figure 2-57.

During RAM operation, read (RA) and write (WA)

addresses are sourced by user logic and the FIFO

controller is ignored. In FIFO mode, the internal

addresses are generated by the FIFO controller and

routed to the RAM array by internal MUXes. Enables

with programmable polarity are provided to create

upper address bits for cascading up to 16 memory blocks.

When cascading memory blocks, the bussed signals WA,

WD, WEN, RA, RD, and REN are internally linked to

eliminate external routing congestion.

RAM

Each memory block consists of 4,608 bits that can be

organized as 128x36, 256x18, 512x9, 1kx4, 2kx2, or 4kx1

and are cascadable to create larger memory sizes. This

allows built-in bus width conversion (Table 2-85). Each

block has independent read and write ports which

enable simultaneous read and write operations.

Clocks

The RCLK and the WCLK have independent source

polarity selection and can be sourced by any global or

local signal.

RAM Configurations

The AX architecture allows the read side and write side

of RAMs to be organized independently, allowing for

bus conversion. For example, the write side can be set to

256x18 and the read side to 512x9.

Both the write width and read width for the RAM blocks

can be specified independently and changed dynamically

with the WW (write width) and RW (read width) pins.

The D x W different configurations are: 128 x 36,

256 x 18, 512 x 9, 1k x 4, 2k x 2, and 4k x 1. The allowable

RW and WW values are shown in Table 2-87.

When widths of one, two, and four are selected, the

ninth bit is unused. For example, when writing nine-bit

values and reading four-bit values, only the first four bits

and the second four bits of each nine-bit value are

addressable for read operations. The ninth bit is not

accessible. Conversely, when writing four-bit values and

reading nine-bit values, the ninth bit of a read operation

will be undefined.

Note that the RAM blocks employ little-endian byte

order for read and write operations.

Modes of Operation

There are two read modes and one write mode:

• Read Nonpipelined (synchronous – one clock edge)

• Read Pipelined (synchronous – two clock edges)

• Write (synchronous – one clock edge)

In the standard read mode, new data is driven onto the

RD bus in the clock cycle immediately following RA and

REN valid. The read address is registered on the read-

port active-clock edge and data appears at read-data

after the RAM access time. Setting the PIPE to OFF

enables this mode.

The pipelined mode incurs an additional clock delay

from address to data, but enables operation at a much

higher frequency. The read-address is registered on the

read-port active-clock edge, and the read data is

registered and appears at RD after the second read clock

edge. Setting the PIPE to ON enables this mode.

On the write active-clock edge, the write data are

written into the SRAM at the write address when WEN is

high. The setup time of the write address, write enables,

and write data are minimal with respect to the write

clock.

Write and read transfers are described with timing

requirements beginning in "Timing Characteristics".

FIFO

Every memory block has its own embedded FIFO

controller. Each FIFO block has one read port and one

write port. This embedded FIFO controller uses no

internal FPGA logic and features:

• Glitch-free FIFO Flags

• Gray-code address counters/pointers to prevent

metastability problems

• Overflow and underflow control

Both ports are configurable in various sizes from 4k x 1

to 128 x 36, similar to the RAM block size. Each port is

fully synchronous.

Read and write operations can be completely

independent. Data on the appropriate WD pins are

written to the FIFO on every active WCLK edge as long as

WEN is high. Data is read from the FIFO and output on

the appropriate RD pins on every active RCLK edge as

long as REN is asserted.

The FIFO block offers programmable almost-empty

(AEMPTY) and almost-full (AFULL) flags as well as EMPTY

and FULL flags (Figure 2-61):

• The FULL flag is synchronous to WCLK. It allows

the FIFO to inhibit writing when full.

• The EMPTY flag is synchronous to RCLK. It allows

the FIFO to inhibit reading at the empty condition.

Gray code counters are used to prevent metastability

problems associated with flag logic. The depth of the

FIFO is dependent on the data width and the number of

memory blocks used to create the FIFO. The write

operations to the FIFO are synchronous with respect to

the WCLK, and the read operations are synchronous with

respect to the RCLK.

The FIFO block may be reset to the empty state.

FIFO Flag Logic

The FIFO is user configurable into various DEPTHs and

WIDTHs. Figure 2-62 shows the FIFO address counter

details.

• Bits 11 to 5 are active for all modes.

• As the data word size is reduced, more least-

significant bits are added to the address.

• As the number of cascaded blocks increases, the

number of significant bits in the address increases.

For example, if four blocks are cascaded as a 1kx16 FIFO

with each block having a 1kx4 aspect ratio, bits 11 to 2 of

the address will be used to specify locations within each

RAM block, whereas bits 13 and 12 will be used to specify

the RAM block.

The AFULL and AEMPTY flag threshold values are

programmable. The threshold values are AFVAL and

AEVAL, respectively. Although the trigger threshold for

each flag is defined with eight bits, the effective number

of threshold bits in the comparison depends on the

configuration. The effective number of threshold bits

corresponds to the range of active bits in the FIFO

address space (Table 2-93).

Note: Inactive counter bits are set to zero.

The active-high CLR pin is used to reset the FIFO to the

empty state, which sets FULL and AFULL low, and EMPTY

and AEMPTY high.

Assuming that the EMPTY flag is not set, new data is

read from the FIFO when REN is valid on the active edge

of the clock. Write and read transfers are described with

timing requirements in "Timing Characteristics" on

page 2-85.

Glitch Elimination

An analog filter is added to each FIFO controller to

guarantee glitch-free FIFO-flag logic.

Overflow and Underflow Control

The counter MSB keeps track of the difference between

the read address (RA) and the write address (WA). The

EMPTY flag is set when the read and write addresses are

equal. To prevent underflow, the write address is double-

sampled by the read clock prior to comparison with the

read address (part A in Figure 2-64). To prevent overflow,

the read address is double-sampled by the write clock

prior to comparison to the write address (part B in

Figure 2-64).

FIFO Configurations

Unlike the RAM, the FIFO's write width and read width

cannot be specified independently. For the FIFO, the

write and read widths must be the same. The WIDTH pins

are used to specify one of six allowable word widths, as

shown in Table 2-95.

The DEPTH pins allow RAM cells to be cascaded to create

larger FIFOs. The four pins allow depths of 2, 4, 8, and 16

to be specified. Table 2-85 on page 2-72 describes the

FIFO depth options for various data width and memory

blocks.

Interface

Figure 2-65 shows a logic block diagram of the

Axcelerator FIFO module.

Cascading FIFO Blocks

FIFO blocks can be cascaded to create deeper FIFO

functions. When building larger FIFO blocks, if the word

width can be fractured in a multi-bit FIFO, the fractured

word configuration is recommended over a cascaded

configuration. For example, 256x36 can be configured as

two blocks of 256x18. This should be taken into account

when building the FIFO blocks manually. However, when

using SmartGen, the user only needs to specify the depth

and width of the necessary FIFO blocks. SmartGen

automatically configures these blocks to optimize

performance.

Clock

As with RAM configuration, the RCLK and WCLK pins

have independent polarity selection

Building RAM and FIFO Modules

RAM and FIFO modules can be generated and included

in a design in two different ways:

• Using the SmartGen Core Generator where the

user defines the depth and width of the FIFO/

RAM, and then instantiates this block into the

design (please refer to Actel’s SmartGen,

FlashROM, Analog System Builder, and Flash

Memory System Builder User’s Guide for more

information).

• The alternative is to instantiate the RAM/FIFO

blocks manually, using inverters for polarity

control and tying all unused data bits to ground.

Other Architectural Features

Low Power Mode

Although designed for high performance, the AX

architecture also allows the user to place the device into

a low power mode. Each I/O bank in an Axcelerator

device can be configured individually, when in low

power mode, to tristate all outputs, disable inputs, or

both. The low power mode is activated by asserting the

LP pin, which is grounded in normal operation.

While in the low power mode, the device is still fully

functional and all internal logic states are preserved. This

allows a user to disable all but a few signals and operate

the part in a low-frequency, watchdog mode if desired.

Please note, if the I/O bank is not disabled, differential I/Os

belonging to the I/O bank will still consume normal

power, even when operating in the low power mode.

The Axcelerator device will resume normal operation

10μs after the LP pin is pulled Low.

To further reduce power consumption, the internal

charge pump can be bypassed and an external power

supply voltage can be used instead. This saves the

internal charge-pump operating current, resulting in no

DC current draw. The Axcelerator family devices have a

dedicated "VPUMP" pin that can be used to access an

external charge pump device. In normal chip operation,

when using the internal charge pump, VPUMP should be

tied to GND. When the voltage level on VPUMP is set to

3.3V, the internal charge pump is turned off, and the

VPUMP voltage will be used as the charge pump voltage.

Adequate voltage regulation (i.e. high drive, low output

impedance, and good decoupling) should be used at

VPUMP

In addition, any PLL in use can be powered down to

further reduce power consumption. This can be done

with the PowerDown pin driven Low. Driving this pin

High restarts the PLL with the output clock(s) being

stable once lock is restored.

JTAG

Axcelerator offers a JTAG interface that is compliant with

the IEEE 1149.1 standard. The user can employ the JTAG

interface for probing a design and performing any JTAG

Public Instructions as defined in the Table 2-102.

Interface

The interface consists of four inputs: Test Mode Select

(TMS), Test Data In (TDI), Test Clock (TCK), TAP Controller

Reset (TRST), and an output, Test Data Out (TDO). TMS,

TDI, and TRST have on-chip pull-up resistors.

TRST

TRST (Test-Logic Reset) is an active-low, asynchronous

reset signal to the TAP controller. The TRST input can be

used to reset the Test Access Port (TAP) Controller to the

TRST state. The TAP Controller can be held at this state

permanently by grounding the TRST pin. To hold the

JTAG TAP controller in the TRST state, it is recommended

to connect TRST to ground via a 1 kΩ resistor.

There is an optional internal pull-up resistor available for

the TRST input that can be set by the user at

programming. Care should be exercised when using this

option in combination with an external tie-off to

ground.

An on-chip power-on-reset (POWRST) circuit is included.

POWRST has the same function as "TRST," but it only

occurs at power-up or during recovery from a VCCA and/

or VCCDA voltage drop.

TDO

TDO is normally tristated, and it is active only when the

TAP controller is in the "Shift_DR" state or "Shift_IR"

state. The least significant bit of the selected register (i.e.

IR or DR) is clocked out to TDO first by the falling edge of

TCK.

TAP Controller

The TAP Controller is compliant with the IEEE Standard

1149.1. It is a state machine of 16 states that controls the

Instruction Register (IR) and the Data Registers (such as

BSR, IDCODE, USRCODE, BYPASS, etc.). The TAP

Controller steps into one of the states depending on the

sequence of TMS at the rising edges of TCK.

Instruction Register (IR)

The IR has five bits (IR4 to IR0). At the TRST state, IR is

reset to IDCODE. Each time when IR is selected, it goes

through "select IR-Scan," "Capture-IR," "Shift-IR," all the

way through "Update-IR." When there is no test error,

the first five data bits coming out of TDO during the

"Shift-IR" will be "10111." If a test error occurs, the last

three bits will contain one to three zeroes corresponding

to negatively asserted signals: "TDO_ERRORB,"

"PROBA_ERRORB," and "PROBB_ERRORB." The error(s)

will be erased when the TAP is at the "Update-IR" or the

TRST state. When in user mode start-up sequence, if the

micro-probe has not been used, the "PROBA_ERRORB" is

used as a "Power-up done successfully" flag.

Data Registers (DRs)

Data registers are distributed throughout the chip. They

store testing/programming vectors. The MSB of a data

to TDO. There are different types of data registers.

Descriptions of the main registers are as follow:

1. IDCODE:

The IDCODE is a 33-bit hard coded JTAG Silicon

Signature. It is a hardwired device ID code, which

contains the Actel identity, part number, and version

number in a specific JTAG format.

2. USERCODE:

The USERCODE is a 32-bit programmable JTAG Silicon

Signature. It is a supplementary identity code for the

user to program information to distinguish different

programmed parts. USERCODE fuses will read out as

"zeroes" when not programmed, so only the "1" bits

need to be programmed.

3. Boundary-Scan Register (BSR):

Each I/O contains three Boundary-Scan Cells. Each cell

has a shift register bit, a latch, and two MUXes. The

boundary-scan cells are used for the Output-enable

(E), Output (O), and Input (I) registers. The bit order

of the boundary-scan cells for each of them is E-O-I.

The boundary-scan cells are then chained serially to

form the Boundary-Scan Register (BSR). The length of

the BSR is the number of I/Os in the die multiplied by

three.

4. Bypass Register (BYR):

This is the "1-bit" register. It is used to shorten the

TDI-TDO serial chain in board-level testing to only

one bit per device not being tested. It is also selected

for all "reserved" or unused instructions.

Probing

Internal activities of the JTAG interface can be observed

via the Silicon Explorer II probes: "PRA," "PRB," "PRC,"

and "PRD."

Special Fuses

Security

Actel antifuse FPGAs, with FuseLock technology, offer

the highest level of design security available in a

programmable logic device. Since antifuse FPGAs are

live-at power-up, there is no bitstream that can be

intercepted, and no bitstream or programming data is

ever downloaded to the device during power-up, thus

making device cloning impossible. In addition, special

security fuses are hidden throughout the fabric of the

device and may be programmed by the user to thwart

attempts to reverse engineer the device by attempting

to exploit either the programming or probing interfaces.

Both invasive and noninvasive attacks against an

Axcelerator device that access or bypass these security

fuses will destroy access to the rest of the device. (refer

to the Design Security in Nonvolatile Flash and Antifuse

FPGAs white paper).

Look for this symbol to ensure your valuable IP is secure.

To ensure maximum security in Axcelerator devices, it is

recommended that the user program the device security

fuse (SFUS). When programmed, the Silicon Explorer II

testing probes are disabled to prevent internal probing,

and the programming interface is also disabled. All JTAG

public instructions are still accessible by the user.

For more information, refer to Actel’s Implementation of

Security in Actel Antifuse FPGAs application note.

Global Set Fuse

The Global Set Fuse determines if all R-cells and I/O

registers (InReg, OutReg, and EnReg) are either cleared

or preset by driving the GCLR and GPSET inputs of all R-

cells and I/O Registers (Figure 2-31 on page 2-47). Default

setting is to clear all registers (GCLR = 0 and GPSET =1) at

device power-up. When the GBSETFUS option is checked

during FUSE file generation, all registers are preset

(GCLR = 1 and GPSET= 0). A local CLR or PRESET will take

precedence over this setting. Both pins are pulled High

during normal device operation. For use details, see the

Libero IDE online help.

Silicon Explorer II Probe Interface

Silicon Explorer II is an integrated hardware and

software solution that, in conjunction with the Designer

tools, allows users to examine any of the internal nets

(except I/O registers) of the device while it is operating in

a prototype or a production system. The user can probe

up to four nodes at a time without changing the

placement and routing of the design and without using

any additional device resources. Highlighted nets in

Designer’s ChipPlanner can be accessed using Silicon

Explorer II in order to observe their real time values.

Silicon Explorer II's noninvasive method does not alter

timing or loading effects, thus shortening the debug

cycle. In addition, Silicon Explorer II does not require

relayout or additional MUXes to bring signals out to

external pins, which is necessary when using

programmable logic devices from other suppliers. By

eliminating multiple place-and-route program cycles, the

integrity of the design is maintained throughout the

debug process.

Each member of the Axcelerator family has four external

pads: PRA, PRB, PRC, and PRD. These can be used to bring

out four probe signals from the Axcelerator device (note

that the AX125 only has two probe signals that can be

observed: PRA and PRB). Each core tile has up to two

probe signals. To disallow probing, the SFUS security fuse

in the silicon signature has to be programmed (see

"Special Fuses" on page 2-90).

Silicon Explorer II connects to the host PC using a

standard serial port connector. Connections to the circuit

board are achieved using a nine-pin D-Sub connector

(Figure 1-9 on page 1-7). Once the design has been

placed-and-routed, and the Axcelerator device has been

programmed, Silicon Explorer II can be connected and

the Explorer software can be launched.

Silicon Explorer II comes with an additional optional PC

hosted tool that emulates an 18-channel logic analyzer.

Four channels are used to monitor four internal nodes,

and 14 channels are available to probe external signals.

The software included with the tool provides the user

with an intuitive interface that allows for easy viewing

and editing of signal waveforms.

Programming

Device programming is supported through the Silicon

Sculptor II, a single-site, robust and compact device

programmer for the PC. Up to four Silicon Sculptor IIs can

be daisy-chained and controlled from a single PC host.

With standalone software for the PC, Silicon Sculptor II is

designed to allow concurrent programming of multiple

units from the same PC when daisy-chained.

Silicon Sculptor II programs devices independently to

achieve the fastest programming times possible. Each

fuse is verified by Silicon Sculptor II to ensure correct

programming. Furthermore, at the end of programming,

there are integrity tests that are run to ensure that

programming was completed properly. Not only does it

test programmed and nonprogrammed fuses, Silicon

Sculptor II also provides a self-test to test its own

hardware extensively.

Programming an Axcelerator device using Silicon

Sculptor II is similar to programming any other antifuse

device. The procedure is as follows:

1. Load the .AFM file.

2. Select the device to be programmed.

3. Begin programming.

When the design is ready to go to production, Actel

offers device volume-programming services either

through distribution partners or via our In-House

Programming Center.

In addition, BP Microsystems offers multi-site

programmers that provide qualified support for

Axcelerator devices.

For more details on programming the Axcelerator

devices, please refer to the Silicon Sculptor II User’s

Guide.

In order to provide the latest information to designers, some datasheets are published before data has been fully

characterized. Datasheets are designated as “Product Brief,” “Advanced,” “Production,” and “Web-only.” The

definition of these categories are as follows:

Product Brief

The product brief is a summarized version of a advanced datasheet (advanced or production) containing general

product information. This brief gives an overview of specific device and family information.

Advanced

This datasheet version contains initial estimated information based on simulation, other products, devices, or speed

grades. This information can be used as estimates, but not for production.

Datasheet Supplement

The datasheet supplement gives specific device information for a derivative family that differs from the general family

datasheet. The supplement is to be used in conjunction with the datasheet to obtain more detailed information and

for specifications that do not differ between the two families.

Unmarked (production)

This datasheet version contains information that is considered to be final.

Export Administration Regulations (EAR)

The products described in this datasheet are subject to the Export Administration Regulations (EAR). They could

require an approved export license prior to export from the United States. An export includes release of product or

disclosure of technology to a foreign national inside or outside the United States.
