Abstract

This article briefly states the idea behind model-based diagnosis and its application to localizing faults in Verilog programs. Specifically this article outlines how to employ a test suite to further reduce the number of fault candidates. For this purpose, we propose the filtering approach and relate it to the concept of Ackermann constraints. Notably, our empirical results demonstrate that our novel technique considerably increases the diagnosis resolution even under presence of only a couple of test cases.
