XJTAG, a leading supplier of boundary scan development tools, has announced an enhancement to its award-winning XJTAG Development System. The new XJIO expansion board improves test coverage and fault diagnosis on complex printed circuits, checks power rail levels and can eliminate the need for costly custom test jigs. The XJIO board improves the test coverage for a Unit Under Test (UUT) by verifying the signals right through to the external connections. In the event of a board failure, the fault diagnosis times can be reduced by as much as half, as the board eradicates the need for time-consuming loopbacks and cable swapping. The XJIO board was developed predominantly for testing circuits with large amounts of digital I/O such as on network cards – particularly if the board has more outputs than inputs or vice-versa, says Dominic Plunkett, XJTAG’s chief technology officer. It features over 200 digital I/Os, and this density can be expanded to many thousands by daisy-chaining the XJIO boards together using the reconfigurable external JTAG connector. The XJIO board can be powered from USB, for quick and portable test setup. Alternatively, if more than 80 mA of current is required, there is a connector for a standard 12 V power supply. The XJTAG Development System meets the growing market need for a cost-effective solution for testing printed circuit boards populated with JTAG devices such as BGA and chip scale devices. Such devices cannot be effectively tested by traditional methods such as flying probes, logic analyzers, oscilloscopes and X-ray systems.
