Abstract

In the framework of model-based design formal modelling, verification and simulation of safety-critical systems are supported by several methods and tools. Interfacing these tools often becomes challenging for heterogeneous systems. The FMI standard enables integration of different simulation tools through artefacts called Functional Mockup Units (FMU) [1]. The FMI standard is mainly based on the concept of scalability of the simulation as it deals with heterogeneous cyber-physical systems. The combination of discrete behaviour and continuous-time environment is a common case study in hybrid simulation. Moreover, another aspect of the FMI is to enhance the capability of the tools. Thus, a collaborative simulation between the Rodin [2] and Ptolemy [3] is leveraged by both platforms. While Event-B is enhanced by new models of computation of Ptolemy,Ptolemy leverages the expressivity and properties validation (theorem/invariant proofs) implemented by Event-B. The main rationale of the co-simulation between Event-B and Ptolemy relies on the intention of dissimilarity and complementarity of the modelling viewpoints. Event-B provides formal modelling by specifying conditions, actions and properties that manage discrete event behaviour, whereas Ptolemy gives a structural viewpoint in terms of actors, components or functions with relation to concerned behaviour. Thus, the association of Ptolemy and Event-B puts together structural and formal aspects.This paper focuses on the collaborative simulation of models supported by both Ptolemy II and Event-B. The ongoing work consists of the design of a diagrammatic co-simulation surface and its application to a controller case study.
