Code replacement libraries

Libraries that define code optimizations for specific target environment

Model Configuration Pane: Code Generation / Interface

Description

The Code replacement libraries parameter specifies code replacement libraries that the code generator uses when producing code for a model. A code replacement library defines code optimizations for a specific target environment.

To select a code replacement library, click the Select button and use the Select code replacement libraries-prioritized dialog box.

Settings

None | named code replacement libraries

None

Does not use a code replacement library.

Named code replacement libraries

Generates calls to multiple platform-specific, compiler, custom, or standard code replacement libraries. The list of named libraries depends on:

Installed support packages.
System target file, language, language standard, and device vendor configuration.
Whether you created and registered code replacement libraries.

Tips

Order the code replacement libraries based on the priority of code replacement. Libraries at the top of the list have a higher priority of replacement.
Specify multiple code replacement libraries enclosed by single quotes and separated by commas.
Before setting this parameter, verify that your compiler supports the library that you want to use. If you select a parameter value that your compiler does not support, compiler errors can occur.
If you set the Shared code placement parameter to Shared location or you generate code for models in a model reference hierarchy:
- For models that are sharing the location or are in the model hierarchy, you must specify the same code replacement library (same name, tables, and table entries).
- If you change the name or contents of the code replacement library and rebuild the model from the same folder as the previous build, the code generator reports a checksum warning (see Manage the Shared Utility Code Checksum). The warning prompts you to remove the existing folder and stop or stop code generation.
If both of the following conditions exist for a model that contains Stateflow^® charts, the Simulink^® software regenerates code for the charts and recompiles the generated code.
- You do not set parameter Shared code placement to Shared location.
- Before regenerating code, you change the code replacement library name or contents.
