<p><b>Abstract</b>—In the absence of information about the layout, test generation, and fault simulation systems must target all bridging faults. A novel algorithm, that is both time and space efficient, for <it>simulating I</it><sub><it>DDQ</it></sub><it>Tests</it> for <it>all two-line bridging faults</it> in combinational circuits is presented. Simulation results using randomly generated test sets point to the computational feasibility of targeting all two-line bridging faults. On a more theoretical note, we show that: The problem of computing <it>I</it><sub><it>DDQ</it></sub> tests for all two-line bridging faults, even in some restricted classes of circuits, is intractable; and, even under some pessimistic assumptions, a complete <it>I</it><sub><it>DDQ</it></sub> test set for all two-line bridging faults also covers all multiple line, single cluster bridging faults.</p>
