准确的故障分析需要准确的故障诊断。以前提出的方法诊断桥接故障，使用单一的固定在字典只适用于小电路，产生大的和不精确的诊断，并没有考虑到拜占庭将军问题桥接故障。我们分析了原有的技术，并通过引入匹配限制，匹配要求，和故障恢复的概念来改进它。我们的新技术不需要标准固定方法所使用的信息，它产生的诊断比原始技术产生的诊断小一个数量级，并且产生的误导性诊断比传统固定诊断少得多。
Precise failure analysis requires accurate fault diagnosis. A previously proposed method for diagnosing bridging faults using single stuck-at dictionaries was applied only to small circuits, produced large and imprecise diagnoses, and did not take into account the Byzantine Generals Problem for bridging faults. We analyze the original technique and improve it by introducing the concepts of match restriction, match requirement, and failure recovery. Our new technique, which requires no information other than that used by standard stuck-at methods, produces diagnoses that are an order of magnitude smaller than those produced by the original technique and produces many fewer misleading diagnoses than that of traditional stuck-at diagnosis.
