Abstract

Increasingly, object-oriented technology, specifically the Unified Modeling Language (UML), is being used to develop critical embedded systems. Several efforts have attempted to translate UML models into formal specification languages, thus enabling the models to be analyzed by model checkers. Unfortunately, the complexity and volume of the analysis results often prevents developers from fully taking advantage of the analysis capabilities. This paper introduces a generic visualization framework, Theseus, that provides developers with a model-based, visual interpretation of the analysis results in terms of the original UML diagrams. Within this framework, a playback mechanism displays the execution path that has led to a model checking violation in terms of the original UML state diagram and a newly generated sequence diagram that depicts the problem scenario. A Theseus prototype supporting the Spin and SMV model checkers has been applied to the analysis of UML models for embedded systems from industry.
