Generate C or C++ Code from Stateflow Blocks

If you have Simulink® Coder™ or Embedded Coder®, you can generate C or C++ code from Simulink models that include Stateflow® blocks.

UseRequired Software LicenseDescription
Rapid prototyping Simulink Coder Generate source code that you can use for real-time and nonreal-time applications, including simulation acceleration, rapid prototyping, and hardware-in-the-loop testing.
Production code deployment Embedded Coder Generate readable, compact, and fast code for use on embedded processors, on-target rapid prototyping boards, and microprocessors used in mass production.

The generated code does not contain code to interface with other blocks in a Simulink model or the MATLAB® base workspace. You cannot generate code only for the Stateflow blocks in a library model. First create a link to the library block in your main model and then generate code for the main model.

Traceability of Stateflow Objects in Generated Code

Traceability comments provide a way to:

  • Verify generated code. You can identify which Stateflow object corresponds to a line of code and track code from different objects that you have or have not reviewed.

  • Include comments in code generated for large-scale models. You can identify objects in generated code and avoid manually entering comments or descriptions.

To enable traceability comments, you must have Embedded Coder or HDL Coder™ software. For C/C++ code generation, comments appear in the generated code for embedded real-time (ert) based targets only. For more information, see Trace Stateflow Elements in Generated Code (Embedded Coder) and Navigate Between Simulink Model and HDL Code by Using Traceability (HDL Coder).
