Abstract
Method and apparatus estimates fault coverage of a set of test vectors to be applied to a circuit containing sequential elements. The apparatus permits sequential elements to be represented as functional blocks rather than combinational circuits with feedback. This is accomplished by taking into account the external state of the sequential element during circuit simulation. The apparatus also takes into account high impedance as possible inputs and outputs.
