Enhanced DO-RE-ME based defect level prediction using defect site aggregation-MPG-D

Predicting the final value of the defective part level after the application of a set of test vectors is not a simple problem. In order for the defective part level to decrease, both the excitation and observation of defects must occur. This research shows that the probability of exciting an as yet undetected defect does indeed decrease exponentially as the number of observations increases. In addition, a new defective part level model is proposed which accurately predicts the final defective part level (even at high fault coverages) for several benchmark circuits and which continues to provide good predictions even as changes are made an the set of test patterns applied
