Abstract

A deterministic BIST scheme for circuits with multiple scan paths is presented. A procedure is described for synthesizing a pattern generator which stimulates all scan chains simultaneously and guarantees complete fault coverage. The new scheme may require less chip area than a classical LFSR-based approach while better or even complete fault coverage is obtained at the same time.
