Abstract :
Heuristics for identifying stuck-open faults for which a robust test can be computed from any stuck-at-test set are presented. Experimental results show that these heuristics can be used to compute robust tests for a large percentage of stuck-upon faults. Since stuck-at test generation is considerably faster than computing a robust test-pair for a given stuck-open fault, these heuristics can be used to speed up the process of computing robust tests for stuck-open faults. The author addresses the problem of computing robust tests for stuck-open faults in static CMOS circuits consisting of NOT, NAND, NOR, AND and OR gates
