Nobody wants to wait a long time for the repair of a product. JTAG/boundary-scan can help to shorten repair times even if no, or only limited, design data is available and can be used to re-program parts for system upgrades.

BOARD REPAIR

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.
