Abstract :
Uses data collected from benchmark circuit simulations to examine the relationship between the tests which detect stuck-at faults and those which detect bridging surrogates. We show that the coefficient of correlation between these tests approaches zero as the stuck-at fault coverage approaches 100%. An enhanced version of the MPG-D model, which is based upon the number of detections of each site in a logic circuit, is shown to be superior to stuck-at fault coverage-based defective part level prediction. We then compare the accuracy of both predictors for an industrial circuit tested using two different test pattern sequences
