The effect of compensating module faults on the reliability of majority voting based VLSI fault-tolerant circuits is investigated using a fault injection simulation method. This simulation method facilitates consideration of multiple faults in the replicated circuit modules as well as the majority voting circuits to account for the fact that, in VLSI implementations, the majority voting circuits are constructed from components of the same reliability as those used to construct the circuit modules. From the fault injection simulation, a survivability distribution is obtained which, when combined with an area overhead expression, leads to a more accurate reliability model for majority voting based VLSI fault-tolerant circuits. The new model is extended to facilitate the calculation of reliability of fault-tolerant circuits which have sustained faults but continue to operate properly. Analysis of the reliability model indicates that, for some circuits, the reliability obtained with majority voting techniques is significantly greater than predicted by any previous model.<>
