Summary: Simulink is a popular tool for model-based development of control systems. However, due to the complexity caused by the increasing demand for sophisticated controllers, validation of Simulink models is becoming a more difficult task. To ensure correctness and reliability of large models, it is important to be able to reason about model parts and their interactions. This paper provides a definition of contracts and refinement using the action system formalism. Contracts enable abstract specifications of model parts, while refinement offers a framework to reason about correctness of implementation of contracts, as well as composition of model parts. An example is provided to illustrate system development using contracts and refinement.
