(CPS), which are computerized systems directly interfacing their real-world surroundings, leverage the construction of increasingly autonomous systems. To meet the high safety demands of CPS, verification of their behavior is crucial, which has led to a wide range of tools for modeling and verification of hybrid systems. These tools are often used in combination, because they employ a wide range of different formalisms for modeling, and aim at distinct verification goals and techniques. To manage and exchange knowledge in the verification process and to overcome a lack of a common classification, we unify different terminologies and concepts of a variety of modeling and verification tools in a
conceptual reference model
(CRM). Furthermore, we illustrate how the CRM can support comparing models and propose future extension.
