General Description

Actel’s newest FPGA family, Axcelerator offers high

performance at densities of up to two million equivalent

system gates. Based upon Actel’s new AX architecture,

Axcelerator has several system level features such as

embedded SRAM (with complete FIFO control logic),

PLLs, Segmentable Clocks, and chip-wide highway

routing.

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). There are two base logic modules:

the Register Cell (R-cell), containing a full-featured flip-

flop and the Combinatorial Cell (C-cell), containing a

four-input MUX with control and carry-chain logic.

Two C-cells and a single R-cell form a Cluster, and two

Clusters comprise a SuperCluster. SuperClusters are

organized into Core Tiles, which are combined to

generate each device (please refer to the Axcelerator

Family FPGAs data sheet for more information).

Additionally, each SuperCluster contains an independent

Buffer Module. Buffer Modules support automatic buffer

insertion for high-fanout nets by the place-and-route

tool, providing better overall system delays while

improving logic utilization.

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.

Product Brief 5

Embedded Memory

The embedded, variable-aspect-ratio SRAM blocks have

separate read and write ports that can be configured

with different bit widths on each port. Available memory

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

4kx1 bit. Additionally, every SRAM block has an

embedded FIFO control unit. The control unit allows the

SRAM block to be configured as a synchronous FIFO, with

programmable DEPTH and programmable

ALMOSTEMPTY and ALMOST-FULL flags in addition to

the normal FULL and EMPTY flags.

The embedded FIFO control unit also contains the

counters necessary for the generation of the read and

write address pointers as well as metastable control

circuitry to prevent erroneous operation. The metastable

control circuitry, when combined with the FIFO’s ability

for asynchronous reads and writes, enables these

embedded structures to be used to cross both clock and

phase domains.

I/Os

The Axcelerator family of FPGAs also features a flexible I/O

structure, supporting a range of mixed voltages with its

bank-selectable I/O: 1.5V, 1.8V, 2.5V and 3.3V. In total,

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). All I/O options are 3.3V tolerant;

the 3.3V PCI option is 5V tolerant with the aid of an

external resistor. All I/O options except 3.3V PCI are hot-

insertion capable.

Each I/O has an input, output, and enable register.

Routing

Tying all of the device resources together is the AX

hierarchical routing structure, enabling the Axcelerator

family’s high performance and utilization. At the lowest

level in and SuperClusters below, there are three routing

structures: DirectConnects, FastConnects, and

CarryConnects. DirectConnects provide very high

performance routing inside the SuperCluster, while

FastConnects provide high performance routing inside

the SuperCluster and to the below SuperCluster.

CarryConnect routing is used between SuperClusters

when building arithmetic functions. The core tile routing

is at the next level. Both vertical and horizontal tracks

run across a row or column of SuperClusters within a

core tile respectively. At the chip level, routing highways

extend across the full length of the device, both north-

to- south and east-to-west.

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 (HCLKs) per device,

which can directly drive the clock input of an R-Cell. Each

of the four routed clocks (CLKs) can drive the clock, clear,

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

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

the clear and preset inputs of each R-Cell as well as each

I/O Register on a chip-wide basis at power up.

Each HCLK and CLK has an associated analog PLL for 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 can operate 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

up to a factor of 64, or multiply and divide settings can

be in any combination as long as the resulting clock does

not exceed the absolute maximum output value (1 GHz).

Additionally, 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 needed to drive the

PLL can be derived from three sources: an external input

pad (configured as either single-ended or differential),

internal logic, or from the output of an adjacent PLL.

Summary

Actel’s Axcelerator family of FPGAs expands the

successful SX-A architecture, adding embedded RAM/

FIFOs, PLLs, and high-speed I/Os. The Axcelerator family

also provides the designer with high-performance at

high-gate counts with high device utilization even with

fixed pins. 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.

Datasheet Categories

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

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.
