Abstract

Editor's note: At-speed scan testing has demonstrated many successes in industry. One key feature is its ability to use on-chip clock for accurate timing in the application of test vectors in a tester. The authors describe new strategies where at-speed scan tests can be applied with internal PLLs. They present techniques for optimizing ATPG across multiple clock domains and propose methodologies to combine both stuck-at-fault and delay-test vectors into an effective test suite.驴Li-C.
