Boundary Scan Test

Test Coach Corporation (Test Coach)

Boundary Scan is a very useful tool for quick, low-cost, re-usable powered-up test of an assembly for basic functionality. Because a fixture with test probes is not required, it is possible to have a working test available within hours or days, rather than weeks. Designers can receive rapid feedback on their prototype boards with tests that can be used again during production testing, as well as for device programming. Given power, ground and Tap port signals, tests can be written to assess the performance of the boundary scan enabled parts on an assembly and other parts on the boundary scan chain.
