This paper shows the various steps a simulation tool has to perform to create a real-time-capable model from a Modelica model. Reduction techniques are often necessary for complex models to meet the realtime requirements. For non-linear models with discontinuities no automatic methods of model reduction are known. The analysis methods supporting developers in identifying critical model parts are explained by means of an illustrating example model.

Keywords: Real-time simulation; hardware-in-theloop; model reduction
