ISTFA2004, ISTFA 2004: Conference Proceedings from the 30th International Symposium for Testing and Failure Analysis, 99-102, November 14–18, 2004,
...Abstract Abstract Bridging faults are a common failure mechanism in integrated circuits and scan-based diagnosis does a good job of isolating these defects. Diagnosis, however, can sometimes result in large search areas. Typically, these areas are caused by long repeater nets. When this happens...

ISTFA2014, ISTFA 2014: Conference Proceedings from the 40th International Symposium for Testing and Failure Analysis, 388-390, November 9–13, 2014,
...Abstract Abstract As the technology keeps scaling down and IC design becomes more and more complex, failure analysis becomes much more challenging, especially for static fault isolation. For semiconductor foundry FA, it will become even more challenging due to lack of enough information. Static...
