   Abstract:
   Techniques are proposed for designing and analyzing efficient space compression for built-in self-testing of VLSI circuits using compact test sets. They are based on identifying certain inherent properties of the test output responses of the circuit under test and the knowledge of failure probabilities. The generalized mergeability criteria of output sequences are developed using the concepts of Hamming distance, sequence weights, cover table and frequency ordering for an arbitrary number of outputs and the effect of failure probabilities on the mergeability criteria is analyzed. The techniques achieve very high fault coverage for single stuck-line faults, with low CUT simulation time and acceptable hardware overhead.
