Abstract

In order to ensure that the co-simulation of Cyber-Physical Systems (CPSs) is possible with as wide a variety of tools as possible, a standard called the Functional Mockup Interface (FMI) has been defined. The FMI provides the means to compute the overall behaviour of a coupled system by the coordination and communication of simulators, each responsible for a part of the system. The contribution presented in this paper is an initial formal model of the FMI standard using the VDM Specification Language. Early results suggest that the FMI standard defines a number of FMU static constraints that are not enforced by many of the tools that are able to export such FMUs.
