Model Configuration Parameters: Code Generation Data Type Replacement

The Code Generation > Data Type Replacement category includes parameters for replacing built-in data type names with user-defined names in the generated code. On the Configuration Parameters dialog box, the following configuration parameters are on the Code Generation > Data Type Replacement pane.

Parameter	Description
Data type replacement	Method for replacing Simulink^® data types in generated code.
Specify custom data type names	Option to replace data type names determined by code generation settings with user-defined data type names in generated code.
Replacement Name: double	Replacement name for `double` built-in data type in generated code.
Replacement Name: single	Replacement name for `single` built-in data type in generated code.
Replacement Name: int32	Replacement name for `int32` built-in data type in generated code.
Replacement Name: int16	Replacement name for `int16` built-in data type in generated code.
Replacement Name: int8	Replacement name for `int8` built-in data type in generated code.
Replacement Name: uint32	Replacement name for `uint32` built-in data type in generated code.
Replacement Name: uint16	Replacement name for `uint16` built-in data type in generated code.
Replacement Name: uint8	Replacement name for `uint8` built-in data type in generated code.
Replacement Name: boolean	Replacement name for `boolean` built-in data type in generated code.
Replacement Name: int	Replacement name for `int` built-in data type in generated code.
Replacement Name: uint	Replacement name for `uint` built-in data type in generated code.
Replacement Name: char	Replacement name for `char` built-in data type in generated code.
Replacement Name: uint64	Replacement name for `uint64` built-in data type in generated code.
Replacement Name: int64	Replacement name for `int64` built-in data type in generated code.

These parameters belong to the Advanced parameters category.

Boolean true identifier	Identifier for Boolean true value
64-bit integer maximum identifier	Identifier for 64-bit integer data limit maximum
16-bit integer maximum identifier	Identifier for 16-bit integer data limit maximum
32-bit integer maximum identifier	Identifier for 32-bit integer data limit maximum
8-bit integer maximum identifier	Identifier for 8-bit integer data limit maximum
64-bit unsigned integer maximum identifier	Identifier for 64-bit unsigned integer data limit maximum
16-bit unsigned integer maximum identifier	Identifier for 16-bit unsigned integer data limit maximum
32-bit unsigned integer maximum identifier	Identifier for 32-bit unsigned integer data limit maximum
8-bit unsigned integer maximum identifier	Identifier for 8-bit unsigned integer data limit maximum
64-bit integer minimum identifier	Identifier for 64-bit integer data limit minimum
16-bit integer minimum identifier	Identifier for 16-bit integer data limit minimum
32-bit integer minimum identifier	Identifier for 32-bit integer data limit minimum
8-bit integer minimum identifier	Identifier for 8-bit integer data limit minimum
Type limit identifier replacement header file	Header file that defines Boolean and data type limit identifiers
Implement images using OpenCV Mat class	Option to represent images as OpenCV class `cv::Mat`
Coder typedefs compatibility	Option to force generation of `rtwtypes.h`.

Configure Simulink Coder Data Type Replacements Programmatically

To programmatically replace the Simulink Coder™ data type names for your model, adjust the ReplacementTypes model parameter, which is a structure. This example code shows how to modify the ReplacementTypes parameter to replace the built-in data type names int8, uint8, and boolean with the custom data type names my_T_S8, my_T_U8, and my_T_BOOL.

model = bdroot;
cs = getActiveConfigSet(model);
set_param(cs,'EnableUserReplacementTypes','on');

struc = get_param(cs,'ReplacementTypes');
struc.int8 = 'my_T_S8';
struc.uint8 = 'my_T_U8';
struc.boolean = 'my_T_BOOL';

set_param(cs,'ReplacementTypes',struc);
