To design and analyze Cyber-Physical Systems (CPSs), engineers should consider computation and physical processes at the same time. Engineers require a design description which is easy to understand. SysML provides diagrammatic notations which are independent of specific disciplines. To express numerical constraints of SysML diagrams, we extend OCL with real arithmetic. Both SysML and extended-OCL require an executable design language to check inconsistencies of constraints. To achieve the above idea, we bridge a gap between SysML and VDM-RT. We propose a framework to embed SysML/extended-OCL into VDM-RT, where we prepare some libraries for extended-OCL. It is unnecessary for engineers to know VDM-RT. Using a unified CPS design description, our approach automatically debugs inconsistencies in whole CPS design. This paper illustrates the proposed method with a car race system.
