<p><b>Abstract</b>—We describe a system for simulating and generating accurate tests for bridging faults in CMOS ICs. After introducing the <it>Primitive Bridge Function</it>, a characteristic function describing the behavior of a bridging fault, we present the Test Guarantee Theorem, which allows for accurate test generation for feedback bridging faults via topological analysis of the <it>feedback-influenced region</it> of the faulty circuit. We present a bridging fault simulation strategy superior to previously published strategies, describe the new test pattern generation system in detail, and report on the system's performance, which is comparable to that of a single stuck-at ATPG system. The paper reports <it>fault coverage</it> as well as <it>defect coverage</it> for the MCNC layouts of the ISCAS-85 benchmark circuits.</p>
