Test Case Generation for Simulink Models using Model Fuzzing and State Solving

Simulink plays an important role in the industry for modeling and synthesis of embedded systems. Ensuring system stability requires using numerous test cases to validate the functionality and safety of the models. However, as requirements increase, the complexity of the models poses new challenges to traditional testing methods. Traditional methods such as constraint solving and random search run into significant obstacles when navigating the complex branching logic and states within models.
