Feedback bridging fault detection using current monitoring
Ding Lu, Carol Q. Tong · 2003
Feedback bridging faults in CMOS circuits are difficult to detect by monitoring logic values. The authors study the possibility of detecting feedback bridging faults by using current monitoring. It is shown that by monitoring current, the feedback bridging faults that cause a metastable state can be detected. Using the same method, the feedback bridging faults can also be detected that lead to oscillations assuming the propagation delay is small.>
