Hierarchical test improves pattern application efficiency

For over 15 years, I've been a big proponent of hierarchical test. Hierarchical test is the commonly used term for creating DFT (design-for-test) features and test patterns at lower level circuit ...

New test points slash ATPG test pattern count

Scan testing has been the foundation of digital-device production test for many years. Several innovations have been developed to keep up with the growth in pattern-set sizes brought about by large ...

Simulation Mismatches Can Foul Up Test-Pattern Verification

Design for testability (DFT) works to make a circuit more testable to ensure that it was manufactured correctly. Alfred Crouch explains the purpose of DFT in his book, Design-For-Test for Digital ICs ...

test pattern

CRTs don’t last forever, and neither do the electronics that drive them. When you have a screen starting to go wonky, then you need a way to troubleshoot which is at fault. A great tool for that is a ...

Reduce Test/Diagnosis Cost with Optimized Scan-Pattern Ordering

Download this article in PDF format. Finding the right balance among test cost, test quality, and data collection for running diagnosis requires consideration of several competing factors. Luckily ...
