You can customize generated identifiers by specifying the Identifier format control parameters on the Code Generation > Identifiers pane in the Configuration Parameters dialog box.

Use the Maximum identifier length parameter to limit the number of characters in function, type definition, and variable names.

Specify a set of names that the code generation process should not use.

Customize the naming of identifiers in the generated code.

Specify parameter values to avoid identifier name collisions with referenced models.

Specify the position and length of name-mangling text in generated identifiers.

Integrate the generated code with your code by specifying the identifiers that correspond to Boolean false and true. Also, specify the identifiers that correspond to data type limits, which the generated code uses to determine overflows.

If you use the code generator to produce C or C++ code, your model must not contain keywords that are reserved for internal use.

To verify your model, you can trace back and forth between generated identifiers and corresponding entities within the model.

There are some exceptions to identifier formatting conventions for type names, non-Auto storage classes, and shared utilities.

There are some limitations pertaining to how autogenerated identifiers comply with the setting of the Maximum identifier length parameter.
