A Multi-View Co-Modeling and Co-Simulation Framework for Heterogeneous Embedded Systems

Embedded and Cyber-Physical systems pose new demands on modeling and simulation aspects. To the architectural and functional representation of (discrete/cyber) execution platform and running application, one must also associate extra-functional representations for the (possibly continuous) physical environment, as well as power and thermal modeling (for monitoring) of the platform itself.Multi-view modeling, using techniques from Model-Driven Engineering, is a powerful conceptual tool to combine the many aspects of CPS representation. In a first part we shall demonstrate how it can be applied to the case of performance/power/thermal aspects added to an embedded platform model. This work was conducted as part of the ANR HOPE project, also labeled as project from the CIM PACADesign Platform. In a second part, we shall consider how to use emerging standard for co-simulation interface, namely FMU-FMI (first developed in the Modelica community), to bridge the step from co-modeling to co-simulation, and also apply multi-physic co-simulation to the case of various physical view of a same component, while it was until now meant to model distinct component interacting in a largersystem, each with its ad-hoc modeling principles. This approach could be used to link in practice several tools found in the CIM PACA Design Platform portfolio.
