Abstract

This paper studies the impact of N-detect scan ATPGpatterns on test quality and associated test costs. Anincremental method for test generation is presented.Metrics to evaluate the richness of the test set arepresented. The natural N-detect profiles of regular one-detecttest sets and the impact to test data volume and testtime of generating additional patterns is studied. Resultsare presented on an Intel® Pentium® 4 processor.Simulation results from evaluating the patterns on layoutextracted and random bridges are presented. Silicon datafrom production test shows the effectiveness of N-detecttests.
