Testing for Single Intermittent Failures in Combinational Circuits by Maximizing the Probability of Fault Detection

1980 IEEE transactions on computers  
Intermittent faults in combinational circuits may appear and disappear randomly; hence, their detection requires many repeated applications of test vectors. Since testing reduces the time available for computation, it is necessary to efficiently minimize the time required for a test, while still achieving a high degree of fault detection. This paper presents an optimal random test procedure to detect intermittent failures. The algorithm maximizes the probability of fault detection by optimally
