Abstract

We discuss an approach to merging Boundary Scan with Ruilt-In Self-Test. The proposed implementation of Boundary Scan represents a snapshot of the Joint Test Advisory Group Recommendation 1.0, while the Built-In Self-Test implements the features of cellular automata. We examine test patterns generated from two distinct sources, one with registers using cellular automata and the other, based on the conventional LFSR configuration. We analyze and illustrate distinctive effects of these patterns on fault coverage of specific designs.
