A method includes executing a test against a first structure and a second structure of a built-in self-test circuit. Each of the first and second structures include a plurality of latches arranged as a plurality of stump chains. The method also includes unloading a first result of the test from the plurality of stump chains of the first structure and a second result of the test from the plurality of stump chains of the second structure. The method further includes determining that the plurality of stump chains of the first structure includes a faulty latch based on the first result not matching the second result.
