We present the concepts and a prototypical implementation of a profiler for the specific analysis of Modelica models running on Scale-RT; a Linux-based real-time kernel. The profiler measures the number of calls and execution times of simulation specific functions calls. Interpreting these results; the developer can directly deduce which components of a simulation model are most promising for optimization. Profiling results and their impact on model optimization are discussed on two case studies from the area of thermodynamic automotive systems.
