I need to compile a simulink model containing S-Functions

I need to compile a model for a specific target that contain S-Function blocks where i don't have the source code to be able to reuse supplier models on a RT target

Hello @Davide Cotterle,

Compiling a model for a specific Real-Time (RT) target that includes S-Function blocks, without access to the source code, presents a unique challenge. S-Functions are a powerful feature of MATLAB/Simulink, allowing for custom simulations through code (C, C++, or MATLAB script) that interacts with the Simulink engine. However, the lack of source code for these S-Functions means you cannot modify them directly to ensure compatibility with your RT target.

Here are a few strategies you might try to address the issue:

• Check Compatibility: First, verify if the binary S-Function is already compatible with your RT target as-is. Some compiled S-Functions are built to run on multiple platforms.
• Use a Wrapper: If the S-Function is not directly compatible, consider writing a wrapper S-Function that calls the binary S-Function. This wrapper can manage any platform-specific adjustments required.

I hope this helps.
