Is it possible to generate the same function for identical subsystems in different top models?

I'm now developing several top models with Simulink. In my plan, code generation should be done seperately for each top mode, and the code generated will be integrated into the same project. In the different top models, there are some identical subsystems. Is there a way to generate the same function for these identical subsystems in the whole project?

Hi JW,

I understand you want to generate reusable code for subsystems shared across multiple models. For this, you can utilize a "Library Subsystem."

Please follow the steps outlined below to use the “Library Subsystem”

• Convert the subsystem into a library block by pasting it in a Blank Library document from Simulink start page.
• Configure it to be atomic unit and support reusable code generation from Code Generation tab in Block Parameters.
• Save the library on MATLAB path and use the library block as subsystem in the models.
• Reusable code files (.C and .H) for the subsystem will be obtained after code generation which can be used throughout the whole project.

Here are the detailed steps to use the “Library Subsystem” from the official MathWorks documentation.

Hope this helps!
