Abstract:
A system on a single integrated circuit chip (SoC) includes a plurality of operational circuits to be tested. A plurality of programmable built-in self-test (pBIST) controllers is connected to respective ones of the plurality of operational circuits in a manner that allows the pBIST controllers to test the respective operation circuits in parallel. An interface is connected to each of the plurality of pBIST controllers for connection to an external tester to facilitate programming of each of the plurality of pBIST controllers by the external tester, such that the plurality of pBIST controllers are operable to test the plurality of operational circuits in parallel and report the results of the parallel tests to the external tester, thereby reducing test time.
