Code replacement libraries - Libraries that define code optimizations for specific target environment - MATLAB (original) (raw)
Main Content
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.

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 locationor 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.
- You do not set parameter Shared code placement to
