Abstract
One embodiment provides a system, comprising methods and apparatuses, for simplifying a set of assumptions for a circuit design, and for verifying the circuit design by determining whether the circuit design satisfies a set of assertions when the simplified set of assumptions is satisfied. During operation, the system can simplify the set of assumptions by identifying, for an assertion in the set of assertions, a first subset of assumptions which, either directly or indirectly, shares logic with the assertion. Furthermore, the system can modify the first subset of assumptions to obtain a second subset of assumptions which either over-approximates or under-approximates the first subset of assumptions. Then, the system can refine the second subset of assumptions to either prove or falsify the assertion.
