Integrating Functional Mock-up units into a formal heterogeneous system modeling framework

• The Functional Mock-up Interface (FMI) standard defines a method for tool- and platform-independent model exchange and co-simulation of dynamic system models. In FMI, the master algorithm, which executes the imported components, is a timed differential equation solver. This is a limitation for heterogeneous embedded and cyber-physical systems, where models with different time abstractions co-exist and interact. This work integrates FMI into a heterogeneous system modeling and simulation framework as process constructors and co-simulation wrappers. Consequently, each external model communicates with the framework without unnecessary semantic adaptation while the framework provides necessary mechanisms for handling heterogeneity. The presented methods are implemented in the ForSyDe-SystemC modeling framework and tested using a case study.
