Abstract

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
