Abstract

Optimization of test stimulus verification by analyzing test stimulus timing information against restriction rules derived from a static analysis of a digital system. The result of this analysis is used to determine test stimulus timing which cannot cause a timing violation and to remove the associated vectors from further checking. Only those vectors which can violate timing constraint rules are checked individually to find states which violate the timing rules.
