If many potential defects exist at each site in an integrated circuit, then as the number of applied test patterns increases, the number of defects which remain undetected decreases monotonically. Modeling this rate of decline in defective part level is a non-trivial problem. We show that the number of times each site is observed serves as a significantly superior basis for modeling this phenomenon when contrasted with the number of faults detected. This "site observation-based" predictor not only increases the accuracy of defective part level prediction, it also provides the first quantitative method for comparing the effectiveness of various ATPG strategies to reduce the defective part level.
