Virtual Integration of Cyber-Physical Systems by Verification

In this position paper, we advocate the use of verification technology to tackle the virtual integration problem for cyber-physical systems. In particular, we advocate the use of high-level modeling languages that allow designers to declaratively specify what properties their architectural models should have, not how to achieve them. We further advocate the use of verification technology to analyze such models, in particular to synthesize concrete architectural models that certifiably satisfy all properties. We discuss our work in this direction and outline some of the challenges. Specifically, we show that virtual integration in the presence of real-time scheduling constraints leads to problems that cannot be dealt with in a compositional manner. They can, however, be handled in a semi-compositional fashion, as we outline in this paper.
