Show Me New Counterexamples: A Path-Based Approach
Résumé
We consider lightweight usage of model-checking for the debugging of Simulink models. A problem is that model-checkers typically return only one counterexample, which may slow down the debugging process. We propose an approach and a tool to produce several counterexamples, exemplifying different property violation patterns for a given version of the design. The approach uses data collected during the replay of the counterexamples to synthesize queries for the model-checker, so that it finds counterexamples that activate new paths. The approach is applied to an academic example and an industrial model from the automotive domain.
