Repairing boards is a challenge especially if design data is missing or incomplete. When that happens you can benefit from JTAG devices on the board (PCB Assembly) you’re working on.

​

See what’s wrong even without design data

​

Boundary-scan in a JTAG device gives access to its pins. Using the devices’ boundary-scan, JTAG Technologies’ AutoBuzz tool can automatically learn the connections between JTAG devices on a known-good board. A full connectivity compare by AutoBuzz between the results from a faulty board against those learned from a known-good board can then reveal failing devices and connections.

​

Enhanced fault search with design data

​

If design data is available the boundary-scan capabilities of the JTAG devices can be used with JTAG Technologies’ Buzz tool to monitor the activity of design signals and to ‘buzz-out’ connections interactively to verify the connectivity between pins. The Clip tool allows you to set-up a sequence of test patterns/vectors making it easy to test non-scan device ‘clusters’.

​

Checking processor-based boards without using firmware

​

In a processor-based design CoreCommander helps you to verify the connectivity between the microprocessor or microcontroller and memory and I/O devices at speed. No embedded software / firmware, emulators or debug tools for software are needed.

​

Re-use tests from design or manufacturing

​

If you have access to the boundary-scan tests used during the design of the product or used in manufacturing then you can directly (re-)use these tests in service. The ProVision run-time platform or any other run-time environment, eg. LabVIEW, LabWindows, TestStand, C, C++, C#, .NET, Visual Basic, ATEasy, can be used.
