Résumé
We present a simulator for resistive bridging and stuck-at faults. In contrast to earlier work, it is based on electrical equations rather than table look-up, thus exposing more flexibility. For the first time, simulation of sequential circuits is dealt with; reciprocal action of fault effects in current time frame and earlier time frames is elaborated on for different bridge resistances. Experimental results are given for resistive bridging and stuck-at faults in combinational and sequential circuits. Different definitions of fault coverage are listed and quantitative results with respect to all these definitions are given for the first time.
