Abstract
Systems and methods of debugging a design under test (DUT) using formal verification are disclosed. In one aspect, a method includes receiving the DUT from a user and a command to find a counter-example of a liveness property of the DUT and a verification trace including a sequence of states structures as a stem followed by a loop. The method further includes receiving a length of the loop from the user and executing a verification algorithm based on the length of the loop. The method further includes determining that the counter-example is found when the execution of the verification algorithm ends after traversing the stem and the loop.
