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.

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);
