Simulink Coder / Custom Code

Description

For a model or nonvirtual subsystem that includes the System Initialize block and a block that uses a SystemInitialize function, the code generator adds external code, which you specify, to the SystemInitialize function that it generates. You can specify code for the code generator to add to the declaration, execution, and exit sections of the function code. If the model also contains an Initialize Function, the code generator places generated code for that block after the code that you specify in the System Initialize block.

If you include this block in a referenced model, the code generator ignores the block for simulation target builds, but processes the block for other system target files.

Note

This block is intended for inserting arbitrary custom code into the generated code in specific locations. See the C Caller and C Function blocks, which are more typically used for integrating custom algorithmic code into a model.

Examples

Integrate External C Code into Generated Code by Using Model Configuration Parameters

Parameters

Specify code that you want the code generator to add to the declaration section of the SystemInitialize function for the model or subsystem.

Specify code that you want the code generator to add to the execution section of the SystemInitialize function for the model or subsystem.

Specify code that you want the code generator to add to the exit section of the SystemInitialize function for the model or subsystem.
