Abstract

In this paper, we present a robust test generation algorithm for combinational circuits based on the Boolean satisfiability method called SPIRIT. We elaborate some well-known techniques as well as present new techniques that improve the performance and robustness of test generation algorithms. As a result, SPIRIT achieves 100% fault efficiency for a full scan version of the ITC'99 benchmark circuits in a reasonable amount of time.
