Testing and debugging boards with BGAs can be difficult because of the physically inaccessible solder balls; and boards with insufficient space for test points are almost as difficult. XJTAG offers you a boundary scan test system that gives a quick and effective solution to both problems. So what is boundary scan? This technique turns many of the pins of microprocessors, FPGAs, and some other ICs into virtual test-points that PC software can use to test your board. It checks for soldering faults like open- and short-circuits under the BGAs and elsewhere across your PCB, pinpointing problems down to pin or net level. It’s all done using the JTAG interface. It also confirms your memories and peripherals are functional, extending test coverage far beyond just the JTAG ICs. And because it doesn’t run code on the board, it’s equally effective if your board can’t boot. That means problems on the memory interface, microprocessor, or clock can easily be debugged. XJTAG also provides a method for ultra-fast in-system flash programming over JTAG when memories are connected to an FPGA. Its algorithm considerably reduces programming times in comparison to other flash programmers. XJTAG offers you test and programming solutions suitable for both R&D prototype testing and production testing. Use them standalone or integrate them with existing bed-of-nails testers or ICT systems such as the Keysight i3070 and Teradyne TestStation, or with SPEA and Takaya flying probe testers. XJTAG software can also be integrated with your existing test software, whether you use TestStand, LabView or LabWindows, or have custom test executives. XJTAG has been developing JTAG controllers and boundary scan test software for over 20 years and is a world-leading boundary scan provider.
