Debugging of Behavioural Models using Counterexample Analysis

Model checking is an established technique for automatically verifying that a model satisfies given temporal property. When the violates property, checker returns counterexample, which sequence of actions leading to state where property not satisfied. Understanding this counterexample debugging specification complicated task several reasons: (i) can contain large number actions, (ii) mostly achieved manually, and (iii) does explicitly highlight source bug hidden in model. This article presents new approach improves usability by simplifying comprehension counterexamples. To do so, we first extract all Second, define analysis algorithm identifies make skip from incorrect correct behaviours, making these relevant perspective. Third, develop set abstraction techniques Our fully automated tool implemented was applied on real-world case studies various application areas evaluation purposes.
