DETECTING SHARED RESCOURCES AND COUPLING FACTORS

Abstract:

A method for dependent failure analysis of a circuit design includes obtaining a circuit design comprising a plurality of circuit elements, and generating a first cone of influence and a second cone of influence for the circuit design. The first cone of influence corresponds to a first one or more inputs of the circuit design. The second cone of influence corresponds to a second one or more inputs of the circuit design. The method further includes determining a first shared circuit element of the circuit elements within a first intersection between the first cone of influence and the second cone of influence. Further, the method includes determining a first coupling factor based on the first intersection between the first cone of influence and the second cone of influence, and outputting the first shared circuit element and the first coupling factor to a memory.
