ICE-1000/ICE-2000 Emulator User’s Guide 1-9
Getting Started
Refer to the online help for information about “target configurator”,
“JTAG/SWD voltage”, “JTAG/SWD frequency”, and “ICE test”.
JTAG/SWD Frequency
The ICE-1000 emulator supports JTAG/SWD clock operation at 5 MHz.
The ICE-2000 emulator supports JTAG/SWD clock operation at 1, 5, 9,
15, 23 and 46 MHz. There is a relationship between the JTAG/SWD fre-
quency and the core clock frequency of the processor. The core clock
should be at least twice the JTAG/SWD frequency in order for the
JTAG/SWD interface to operate properly. On newer Analog Devices pro-
cessors, the core clock is a variable set by software.
If the core/JTAG/SWD clock relation is not followed, scan failures
may prevent the emulator from connecting to the processor.
Troubleshooting and Warranty
To provide comprehensive troubleshooting advice and warranty
information for all emulator and EZ-KIT Lite® products, Analog Devices
maintains two Engineer-to-Engineer Notes—Emulator and Evaluation
Hardware Troubleshooting Guide for VisualDSP++ Users (EE-175) and
Emulator and Evaluation Hardware Troubleshooting Guide for CCES Users
(EE-356). Both EE-Notes are available online at http://www.analog.com.
The EE-Note can be used to resolve most installation, connection, and
software issues affecting the use of Analog Devices in-circuit emulators
(ICEs) and EZ-KIT Lite evaluation systems, avoiding the need to return
the suspected faulty emulator or EZ-KIT Lite board. Please carry out all
troubleshooting steps outlined in this document before contacting Analog
Devices Processor Tools Support.
