Two-folded tool support for evaluating the effect of such adaptations is presented here: (1) A ModelComparator for the systematic comparison of simulation results from different versions of the model and (2) an RT-Profiler for measurements and analyses of function calls during RT simulations. The ModelComparator facilitates verification of a model adapted for real-time execution to ensure that it will produce sufficiently accurate results at selected operation points. The RTProfiler takes the specific code structure of simulation models into account when measuring execution times. It directs the developer to those parts that are most promising for model adaptations.
We consider OpenModelica and SimulationX as modeling and code generation frameworks for realtime simulation. The procedure of model adaptations and the use of the analysis tools therein are exemplified in small case studies.
