Abstract

This paper presents two algorithms for generatingcompact test sets for combinational and full scan circuits under the transition and CMOS stuck-open faultmodels; Redundant Vector Elimination (RVE) and Essential Fault Reduction (EFR). These algorithms together with the dynamic compaction algorithm are incorporated into an advanced ATPG system for combinational circuits, called MinTest. The test sets generated by MinTest are 30% smaller than the previouslypublished two-pattern test set compaction results forthe ISCAS85 and full scan version of the ISCAS89benchmark circuits.
