Abstract:
A method for sequential equivalence checking (SEC) of two representations of an electronic design includes selecting by a processor a plurality of cutpoints in the two representations of the electronic design, rendering the two representations of the electronic design abstracted; executing by the processor an assume-guarantee (AG) proof on the two abstracted representations of the electronic design; identifying by the processor a failed assertion indicating non-equivalence of a signal pair relating to one of the cutpoints; and performing by the processor a simulation on the two representations of the electronic design by successively inputting input stimuli of a trace corresponding to the failed assertion in a sequential order in which the input stimuli appear in the trace at inputs of the two representations of the electronic design to identify whether there is one or a plurality of additional non-equivalent signal pairs relating to other cutpoints of said plurality of cutpoints.
