Introduction to Profiling Models

This example shows how to use the Simulink Profiler to examine the slAccelDemoF14 model and identify issues that can contribute to poor simulation performance. Consider using the Simulink Profiler to manually optimize model settings, identify simulation slowdowns, and resolve performance bottlenecks.

To automatically optimize your model and achieve faster simulation, see Improve Simulation Performance Using Performance Advisor.

To learn more about accelerator modes for faster simulation, see What Is Acceleration?.

Activate the Profiler

To activate the Simulink® Profiler, in the Simulink Editor, on the Debug tab, under Performance Advisor, click Simulink Profiler. You can also issue a set_param command at the command prompt.

modelName = 'slAccelDemoF14';

Run Simulation

While the simulation runs, the profiler is collecting data for the report. Once the simulation is complete it creates an HTML report.


View Report

A detailed profiling report is shown in a docked panel on the Simulink Editor. Select a row to see the breakdown of the self-time of the specific model element in the Property Inspector.

Share Report

You can share the profiling report with others as an HTML report or as a MAT file. To share your profiling run, select the desired run from the Run menu of the Profiling Report. Then select your desired export format from the Share menu on the Toolstrip.
