Header files

Custom name for header files

Model Configuration Pane: Code Generation / Code Placement


Specify customized name for generated header files.


This parameter:

  • Appears only for ERT-based targets.

  • Requires Embedded Coder® when generating code.


$R$E (default) | macro text

Default: $R$E

Enter a macro that specifies whether, and in what order, certain text is to be included in the generated identifier. The macro can include a combination of custom user text and these format tokens.


Insert the file type. $E represents these instances of file types:

  • capi

  • capi_host

  • dt

  • testinterface

  • private

  • types

Required. In files of other types, $E does not generate text.


Insert root model name into identifier, replacing unsupported characters with the underscore (_) character.

Required for model referencing.


Insert text that you specify for the $U token. To specify this text, use the Custom token text parameter.

In the generated file name, adjacent tokens are separated by the underscore (_) character, even if a token does not generate text.

Custom naming is supported only for .h and .hpp files. When you have model hierarchy, custom naming is applicable to only the root model.
