Abstract

A recent work describes an ATPG for path delay faults that limits the power dissipated by the test patterns to a given bound. However, the power dissipated by the intermediate patterns while applying the test patterns in a sequence is not considered. Experiments with test patterns derived from different ATPGs has shown that the switching activity due to intermediate patterns dissipate considerable power. This paper proposes a method to incorporate stability functions in a functional ATPG to derive test vectors that guarantee reduced power dissipation by the intermediate patterns without loss in PDF coverage.
