In this paper the problem of testing high speed CMOS circuits is considered. A test methodology based on a Built-in Self-Test scheme adapted to TSPC circuits is proposed. We show through HSpice simulations on netlists extracted from layout that this scheme can operate at more than 580 MHz. Moreover, an efficient solution to the problem of redesigning an easily testable functionally equivalent logic block to eliminate hard to test and untestable faults in TSPC circuits is introduced.
