Abstract:
An LBIST captures pseudo-random values from a pseudo-random pattern generator. Next, the LBIST stabilizes an untimed logic path by inputting the captured pseudo-random value into the untimed logic path. In turn, the LBIST tests one or more timed signal transitions that are dependent upon the stabilized untimed logic path.
