Automated Graph-Based Fault Injection Into Virtual Prototypes for Robustness Evaluation

Modeling and validation of complex and highly connected systems involved in safety-critical tasks are great challenges today with little support in automation. A graph structure models the system and the faults component-by-component in the proposed approach and specifies valid systems. Automated generation and execution of test cases for every valid combination of components is done as well as monitoring and assessment of the system behavior. The integrated fault description provides faults from single bit-flip to comprehensive scenarios. The simulation is supervised and executed by the graph, which adapts the faults automatically during simulation with respect to the simulation state.
