I have a few scripts that I am looking to export for running in an embedded system. One of the script (class) has a handle for a simulink model and handles simulating the model. Another script is an event listener listening to a comms network.

I tried using the Application Compiler and it seems to setup the communication nodes fine but errors out when setting up the simulink dependent scripts.

I am aware of the capability of exporting the model as a standalone FMU and was considering writing python code for the embedded system that functions identically to my scritps and uses this FMU.

Is there a good way to export these scripts/models for running on an embedded system that doesn't involve me completely re-writing my scripts?

You can have a look at the Coder family of products for embedded code generation https://www.mathworks.com/products/embedded-coder.html.

You can convert the Simulink model to C/C++ code for an embedded target with Embedded Coder and MATLAB scripts can be converted to C/C++ code using MATLAB Coder, but it remains to be seen whether your specific code is compatible with the restrictions imposed by these products https://www.mathworks.com/help/rtw/ug/code-generation-limitations-for-model-reference.html.

Jasvin, Thank you for the quick response.

I am currently looking into these options. I believe I will need to seperately generate my matlab scripts in a seperate environment and compile the models and execute them from that environment.

The main target environment is a headless computer operating an x64 Linux OS. Our model is fixed step simulation model using only simulink or simscape blocks.

I had mentioned FMU in my original question but I am not against using embedded coder. What are the advantages between an FMU vs code generated by the embedded compiler or code generated by the simulink compiler.
