ABSTRACT:
A method for verifying a property associated with a target circuit is provided that includes receiving information associated with a target circuit, the information identifying a property within the target circuit to be verified. One or more partitioned ordered binary decision diagram (POBDD) operations are then executed using the information in order to generate a first set of states at a first depth associated with a sub-space within the target circuit. Bounded model checking may be executed using the first set of states in order to generate a second set of states at a second depth associated with the sub-space within the target circuit. The first set of states may be used as a basis for the second set of states such that the second depth is greater than the first depth.
