When generate C/C++ code with Embdded Coder, output of some block in some Toolbox has Model_data.c file more than 100 Mb

Can I reduce Model_data.c file size by changing some configuration in Simulink?

Hi 재욱 임,

To reduce or optimize the size of the C file generated by Embedded Coder, consider the following strategies:

1-Split the generated files - Instruct the embedded coder to create multiple files as its output, rather than putting every function in the same C file.For more information please refer to https://www.mathworks.com/matlabcentral/answers/93591-can-i-separate-or-split-large-generated-files-into-smaller-files-created-by-simulink-coder-8-0-r201

2-Code Generation Settings - Adjust or modify the code generation settings to optimize the generated code. Plese refer https://www.mathworks.com/help/ecoder/ug/generating-code-using-embedded-coder.html

3-Subsystem Partitioning - If your model has large subsystems, consider partitioning them into smaller, more manageable subsystems.

Hope this helps.
