Replicant simulation

In one embodiment, a method comprises partitioning a circuit description into a plurality of simulateable partitions. The partitioning is independent of a hierarchy specified in the circuit definition. The method also comprises sorting the plurality of simulateable partitions into one or more groups, wherein each simulateable partition included in a given group is equivalent to each other partition in the given group. Further, the method comprises simulating a first simulateable partition in the given group responsive to one or more input stimuli to the first simulateable partition. For each other simulateable partition in the given group that has approximately the same input stimuli as the first simulateable partition, the method still further comprises using a result of simulating the first simulateable partition as a result of the other simulateable partition.
