Model Checking application on Function Block Diagram model

Model Checking represents a mathematical method of formal verification which can prove that model satisfies its specified requirements. This article describes an approach that utilizes Function Block Diagram (FBD) models. The key benefit of this approach is the automatic transformation of the original model into a formal model which can be checked by Model Checking. In this way Model Checking can be easier integrated in the standard development process. The presented approach was developed together with the new verification process. This process can be used for the verification of safety-critical systems.
