Improving Timing-Independent Testing of Crosstalk Using Realistic Assumptions on Delay Faults

Abstract

Test generation methodology previously developed for crosstalk targets in the presence of manufacturing defects and process variations results in low coverage. In this paper, under a realistic assumption about the nature of manufacturing defects, we show that by incorporating two new concepts, namely, non- criticality and delay-superiority, significantly higher coverage of targets and lower test generation and test application costs are achieved.
