Code Generation: Data Type Replacement Tab Overview

Replace built-in data type names with user-defined replacement data type names in the generated code for your model.

Configuration

This tab appears only if you specify an ERT based System target file.

If your application requires you to replace built-in data type names with user-defined replacement data type names in the generated code:

1. Select Replace data type names in the generated code.

2. Selectively specify replacement data type names to use for built-in Simulink data types in the Replacement Name fields.

Replace data type names in the generated code

Specify whether to replace built-in data type names with user-defined data type names in generated code.

Settings

Default: off

On

Displays the Data type names table. The table provides a way for you to replace the names of built-in data types used in generated code. This mechanism can be particularly useful for generating code that adheres to application or site data type naming standards.

You can choose to specify new data type names for some or all Simulink built-in data types listed in the table. For each replacement data type name that you specify:

• The name must match the name of a Simulink.AliasType object that exists in the base workspace.

• The BaseType property of the associated Simulink.AliasType object must be consistent with the built-in data type it replaces.

• For double, single, int32, int16, int8, uint32, uint16, and uint8, the BaseType of the replacement data type must match the built-in data type.

• For boolean, the BaseType of the replacement data type must be either an 8-bit integer or an integer of the size displayed for Number of bits: int on the Hardware Implementation pane of the Configuration Parameters dialog box.

• For int, uint, and char, the size of the replacement data type must match the size displayed for Number of bits: int or Number of bits: char on the Hardware Implementation pane of the Configuration Parameters dialog box.

An error occurs if a replacement data type specification is inconsistent.
