摘要
In this paper we analyze fault behaviors of internal feedback bridging faults by using a simple circuit model consisting of 2-input NAND gate and NOT gate. From analysis results we find that they are more complex than those associated with external feedback bridging faults. We expose that they cause internal oscillation and IDDQ-only failure as well as latch and oscillation behavior. We also discuss methods for detecting this kind of fault.
