JTAG Technologies Answers Demand for On-board Test Control

For the first time since the introduction of the IEEE Std. 1149.1 in 1990 existing USB to JTAG resources, which design engineers frequently now include on their boards, can be linked to high-level boundary-scan test software. In conjunction with FTDI Ltd, JTAG Technologies is pleased to offer a support option for the popular FTDI 2232D and the new FT2232H/4232H (Hi-speed USB 2.0) devices that allow direct connection from PC to target (UUT) via a standard USB cable.

Anticipated users of this support option will include field repair technicians, who will be able to reduce their tool inventory, and design engineers looking to exercise JTAG circuitry during the hardware debug phase. The device support extends from the JTAG ProVision application development software through to its run-time, production solutions - as well as the free 'BUZZ' and low-cost 'CLIP' and 'SCRIPT' JTAG Live modules, which can be downloaded from www.jtaglive.com.

Peter van den Eijnden, Managing Director for JTAG Technologies commented: “Once designed into a board and configured appropriately, the FTDI parts act the same as a regular JTAG controller that can be selected from our software’s instruments menu. This has a huge effect on the usefulness of boundary-scan throughout a product’s lifecycle since it makes in-service or field service of PCBs and systems a far more realistic proposition.”

Daniel McCaffrey Marketing Manager at FTDI states: “We fully support JTAG Technologies’ move to broaden the appeal of built-in (PCB) test feature through the use of FTDI’s proven technology. This type of enhancement is a winning proposition for suppliers and customer alike.”

Existing users of JTAG Technologies’ software with a valid support contract can apply for the ‘bolt-on’ FDTI support package via their local sales representative. Prospective users of JTAG ProVision or PIP/xx can also request a demonstration of the technology in action.

FTDI Ltd has been at the forefront of IC USB to serial bus conversion hardware development for over 15 years, initially supplying devices to help convert legacy PC peripherals to USB. Its full range now includes USB 2.0 full speed and Hi Speed converter ICs with fully supported drivers, and the new Vinculum 2 USB host interface IC with its own royalty-free IDE.
