The design complexity of systems on a chip drives the need to reuse legacy or intellectual property cores, whose gate-level implementation details are unavailable. The core test depends on manufacturing technologies and changes permanently during a design lifecycle. The purpose of this paper is to assist to designer in the decision making how to test transition faults of re-synthesized cores. We have performed various comprehensive experiments with combinational benchmark circuits. Our experiments show that the test sets generated for a particular circuit realization fail to detect in average only less than 1.5% of the transition faults of the re-synthesized circuit but in some cases this figure is more than 9%. The same trends are valid for stuck-at faults of different implementations, too. The double-detection test sets declined almost twice both the maximum and the average percent of undetected transition faults for all implementations of the circuits, except one singular implementation of one circuit.
