Abstract

This paper summarizes the final research results of the ITEA3 project EMPHYSIS (embedded systems with physical models in the production code software). Its core achievement is the new open eFMI Standard enabling automated workflows from high-level mathematical models of physical systems (referred to as physical models) to automotive compliant embedded software. eFMI (FMI for embedded systems) defines a container architecture for model exchange and testing. Multiple representations from an intermediate representation of sampled algorithms (GALEC) to production and binary code for specific embedded targets are maintained in a traceable workspace. The successful integration of the developed eFMI tooling is demonstrated by a comprehensive open source Modelica test cases library and industrial demonstrators. The readiness of the proposed approach is proven by compliance checks according to common automotive code quality standards like MISRA C:2012 and a performance benchmark in terms of runtime and resource demand in comparison with state-of-the-art hand coded solutions.
