Abstract
In one embodiment, a method for circuit verification using multiple engines includes running multiple traces on a circuit using multiple reachability algorithms, selecting an effective reachability algorithm for the circuit from among the multiple reachability algorithms according to a comparison of results of the multiple traces with each other, generating a set of initial states for the selected effective reachability algorithm using states reached in the plurality of traces, and executing the selected effective reachability algorithm using the generated set of initial states to verify the circuit.
