Abstract: Simulation is widely used for the early validation and evaluation of embedded systems. In the case of complex systems consisting of highly heterogeneous components, a tradeoff occurs between the simulation accuracy and time interval under observation. A possible solution for this problem is run-time co-simulation model switching. It enables the test engineer to define the simulation intervals with high accuracy and the intervals of high performance. In this work, we propose a framework for the systematic decision of the component models to be used according to the goals and current status of the simulation. In combination, we further propose a new adaptive approach for run-time co-simulation model switching. The proposed approach is illustrated by the simulation of automotive distributed embedded systems.
