Unified Simulation, Visualization, and Formal Analysis of Safety-Critical Systems with

We give an overview of the Open image in new window (pronounced “safety sharp”) framework for rigorous, model-based analysis of safety-critical systems. We introduce Open image in new window ’s expressive modeling language based on the Open image in new window programming language, showing how Open image in new window ’s fault modeling and flexible model composition capabilities can be used to model a case study from the transportation sector with multiple design variants. Fully automated formal safety analyses are conducted for the case study using the explicit-state model checker LTSmin. Analysis efficiency is evaluated in comparison with other safety analysis tools and model checkers.
