描述了一种新的诊断故障模拟器，它可以使用来自单个固定故障的故障模拟的信息来诊断组合电路中的反馈和非反馈桥故障。使用考虑拜占庭将军问题存在的现实故障模型。表示可能涉及缺陷的节点的集合根据故障向量的逻辑和故障模拟进行划分。该方法已在包含布尔原语的多个大型组合基准电路上针对两线桥故障进行了演示，并且对于非反馈桥故障实现了超过 98% 的准确度，对于反馈桥故障实现了超过 85% 的准确度，并且具有良好的诊断分辨率。
A new diagnostic fault simulator is described that diagnoses both feedback and nonfeedback bridge faults in combinational circuits while using information from fault simulation of single stuck-at faults. A realistic fault model is used which considers the existence of the Byzantine Generals problem. Sets representing nodes possibly involved in a defect are partitioned based on logic and fault simulation of failing vectors. The approach has been demonstrated for two-line bridge faults on several large combinational benchmark circuits containing Boolean primitives and has achieved over 98% accuracy for nonfeedback bridge faults and over 85% accuracy for feedback bridge faults with good diagnostic resolution.
