Abstract :
Conventional methods cannot effectively verify path delays of designs employing IP circuits (cores) whose implementation details are hidden. A delay fault ATPG method for such designs is proposed that employs a scan technique called selectively transparent scan (STS). Experimental results are presented which show that the STS method can robustly test paths of a specified delay range in core-based circuits, and substantially reduce test length
