本文提出了桥接时钟线和栅极信号线之间的故障的诊断方法。应用基于扫描的模拟方法，同时假设仅使用基于扫描的冲洗测试。鉴于初始状态起着重要作用，我们考虑两种可能的情况：1）假设所有触发器都复位表，2）触发器不复位表。为了处理由于不可重置表触发器而导致的未知状态，我们引入启发式技术。通过基准电路的实验结果评估了所提出方法的有效性。
This paper presents diagnosis methods for bridging faults between a clock line and a gate signal line. Scan-based simulation methods are applied while assuming that only scan-based flush tests are used. In view of the fact that initial states play an important role, we consider two possible scenarios: 1) all flip-flops are assumed to be reset table, and 2) flip-flops are not reset table. In order to handle unknown states due to the non-reset table flip-flops, we introduce heuristic techniques. The effectiveness of the proposed methods are evaluated by the experimental results for benchmark circuits.
