Abstract
The present disclosure relates to a method for formal verification of an integrated circuit design. The method may include providing an electronic design associated with the integrated circuit. The method may further include generating one or more faults in a cone of influence of an assertion and placing a constraint configured to model an original design for the one or more faults. The method may also include initiating formal verification on the electronic design while ignoring all electronic design constraints. The method may further include determining if the assertion is passing, wherein determining includes activating an original design for a subset of faults. If the assertion is passing, the method may include activating a single fault from the subset, determining if the assertion is passing and if the assertion does pass, deleting the single fault from the subset.
