提出了一种将预计算信息存储与动态计算相结合的同步时序电路桥接故障诊断技术。该方法解决了诊断所需的准确性、存储要求和计算复杂性。自适应模拟桥接故障行为和在选择向量上存储故障状态信息的组合确保了低存储要求的准确性。将自适应仿真、状态存储和路径跟踪相结合，计算量较低。给出了ISCAS89基准电路的实验结果。
A diagnosis technique that integrates the storage of precomputed information with some dynamic computation for the diagnosis of bridging faults in synchronous sequential circuits with no-scan or partial-scan is presented. The method addresses the accuracy, storage requirements, and computational complexity required for diagnosis. A combination of adaptively simulating the behavior of a bridging fault and storing faulty state information at select vectors ensures accuracy with low storage requirements. The combination of adaptive simulation, state storage, and pathtracing has low computational requirements. Experimental results are provided for the ISCAS89 benchmark circuits.
