A fast nonenumerative automatic test pattern generator for path delay faults
This paper presents a nonenumerative automatic test pattern generator for robustly testable path delay faults. In contrast to earlier work [26], the pattern generator takes into consideration the conditions for robust propagation while sensitizing sets of paths. This increases the probability of testing them robustly with a single test. Novel algorithms are described which identify sets that contain many such potentially compatible paths. The number of detected faults is estimated using a simple and fast method. The approach compares favorably to [26] in both fault detection and time performance.
