JTAG Test Creation: Writing JTAG Board Test Scripts for Device Programming, Prototype Bring Up, JTAG Test and JTAG Debug

The Joint Test Access Group (JTAG) Production Test, JTAG Debug/Prototype Bring Up and JTAG FLASH Programming tools are powerful, cost-efective and easy to use products that help you save both time and money when testing your products. Access to the devices on your board is provided by placing a standard JTAG connector onyour circuit board. For more information on each of these tools follow the links below:

JTAG Manufacturing Test Tools - Boundary-Scan IEEE 1149.1 JTAG Test Tools allow maximum test coverage, are simple to set up and use and provide the best value in the industry. Learn more about JTAG Test Tools>>

JTAG Board Bring-Up - Start debugging your new hardware as early as possible. Detect shorts, opens and "stuck at" faults in addition to testing all devices on the JTAG chain. Program on-board devices using JAM or other popular formats. Learn more about JTAG Prototype Debug and Bring up>>

JTAG FLASH Programming - Program popular FLASH devices in-circuit quickly and easily. Learn more about JTAG FLASH Device Programming>>

JTAG Debug Tools - Write custom tests for devices on and off the JTAG chain. Step, run to breakpoints, send patterns and sequences to your board. Learn more about JTAG Debug>>

Cost Effective JTAG Emulation with GDB Debugging To help you leverage the cost effectiveness of popular Open Source Debug tools like: GDB/DDD, Eclipse, Insight and others, the Guardian-SE JTAG Emulator (ICE) works in concert with these GDB based tools to give you the best GDB hardware-assisted JTAG debug experience available today.
To further jump start your development, ETC's development tools come “ready-to-run” with popular off-the-shelf reference boards, tools and environments.

Tools for Every Phase of Development: JTAG Emulation, JTAG Debug, JTAG Board Bring Up, JTAG FLASH ProgrammingOur JTAG Debug Tools are delivered in three configurations allowing you to select just the right amount of debug power needed for the task at hand:

The Guardian-SE JTAG Emulator/ICE - Low cost board bring-up and debug

The Guardian-SE JTAG Emulator/ICE with Agile-Utilities - Adds a powerful GUI for board bring-up, and JTAG FLASH Programming

The Guardian-SE JTAG Emulator/ICE and Agile-DB Source JTAG Level Debugger - Our high end comercial source level JTAG debugger

The sections below provide detail on each of these configurations.

The Guardian-SE JTAG ICE (JTAG Emulator)
The Guardian-SE JTAG ICE was specifically designed to meet a whole range of development needs from board bring-up, to boot loader debug, to OS and applications debug and manufacturing test support.

Engineers bringing up new hardware can use the Guardian-SE JTAG probe's command line interface (Via serial line or telnet) for access to a wide array of debug and board test services such as:

JTAG Hot plug command - non-intrusivily plug into a target system and display the state

JTAG Target Processor Auto ID command - tells you what processor is on your board

JTAG Target snapshot commands - grab target status--even while the target is running

JTAG Target FLASH Auto ID command - tells you what FLASH device is on your board

JTAG Turnkey target FLASH operations - lock, unlock, erase, program, ID, verify

Memory read and write commands

A full suite of built-in memory tests - scope loops, walking 1s, etc.

Register access and control commands with support for all on-chip registers

Instruction and data Cache access and control commands

MMU access and control commands

JTAG Run control commands: reset, go, halt, step, break, download code and data files

Dissessamble target memory

Full command file and macro playback for hardware bring-up and test automation

If source level JTAG debugging is required,  Guardian-SE works out of the box with all popular open source GDB-based debuggers like: DDD, Insight, GDB and Eclipse or our own Agile-DB debug tool. More detail on Guardian-SE More detail on GDB Based Debugger Support



The Guardian-SE JTAG ICE with Agile-Utilities
When combined with Guardian-SE, Agile-Utilities adds a Flexible Windows or LINUX GUI to the Guardian-SE JTAG Emulation Tool. Agile-Utils provides fast access to all the power of the Guardian-SE command line interface for PowerPC, MIPS, XSCale and ARM processors. Engineers who prefer a GUI interface for board bring-up and debug will love the drag-and-drop GUI power of Agile-Utils. If source level debugging is required,  Guardian-SE works out of the box with all popular open source GDB-based debuggers like: DDD, Insight, GDB and Eclipse or our own Agile-DB debug tool.
