PEST-a tool for implementing pseudo-exhaustive self test

Pseudo-exhaustive self-test (PEST) is a built-in self-test (BIST) methodology. This methodology guarantees 100% stuck-at fault coverage without fault simulation or test generation. PEST is a software tool developed to implement pseudo-exhaustive self-test. PEST has been used in two chip designs. This work briefly describes the pseudo-exhaustive self-test methodology and its implementation in the PEST software tool. Comparative advantages of pseudo-exhaustive self-test over other BIST methodologies are discussed. Before concluding with a short user guide, some facts about the tool are presented and reference given
