ABSTRACT:
In one embodiment, a method for verifying one or more particular properties of a circuit using a learning strategy to determine suitable values of particular verification parameters includes classifying each of multiple properties of a circuit according to circuit size and selecting a candidate property from the properties. The candidate property set includes one or more particular properties from each property class. The method also includes attempting to verify one or more particular properties of the circuit using the candidate property set and particular values of particular verification parameters. The method also includes determining suitable values of the particular verification parameters according the attempted verification of the particular properties of the circuit using the candidate property set and the particular values of the particular verification parameters.
