ABSTRACT:
Vector-specific test circuitry is added to an existing circuit design to enable improved fault test coverage by an existing fault test. Each vector-specific test circuit is designed to produce a single output indicative of whether any faults were detected in a plurality of previously unobservable node states produced in response to an associated test vector.
