When you simulate a model, use these guidelines to choose the right procedure.
|Do this step...||When...|
Speed up simulation
You have a large model with many blocks.
See Speed Up Simulation.
Include custom code
You want to take advantage of legacy code that augments model capabilities and also include custom variables and functions that you share between your custom code and Stateflow® generated code. See Integrate Custom C/C++ Code for Simulation.
Include custom code only for library charts
You want to provide custom code in a portable, self-contained library for use in multiple models.
To choose the right procedure for simulation, find the highlighted block that describes your goal and see the corresponding section in Integrate Custom C/C++ Code for Simulation.
