EnglishVacuum cleaning is a mandatory process when an implementation is verified with respect to a specification modeled by means of formal properties. In fact, vacuum cleaning looks for properties that, passing vacuously (e.g., an implication whose antecedent is always false), may lead verification engineers to a false sense of safety. Current approaches to vacuum cleaning, generally, exploit formal methods to provide an interesting witness proving that a property does not pass vacuously. However, such approaches are as complex as model checking, and they require to define and model check further properties, thus increasing the verification time. This paper proposes an alternative approach, based on fault simulation, that requires neither the definition of new properties, nor the use of model checking. Experimental results show the high efficiency of this approach.

| Abstract: | Vacuum cleaning is a mandatory process when an implementation is verified with respect to a specification modeled by means of formal properties. In fact, vacuum cleaning looks for properties that, passing vacuously (e.g., an implication whose antecedent is always false), may lead verification engineers to a false sense of safety. Current approaches to vacuum cleaning, generally, exploit formal methods to provide an interesting witness proving that a property does not pass vacuously. However, such approaches are as complex as model checking, and they require to define and model check further properties, thus increasing the verification time. This paper proposes an alternative approach, based on fault simulation, that requires neither the definition of new properties, nor the use of model checking. Experimental results show the high efficiency of this approach. |
