Code replacement library
Library that defines code optimizations for specific target environment
Model Configuration Pane: Code Generation / Interface
The Code replacement library parameter specifies a code replacement library that the code generator uses when producing code for a model. A code replacement library defines code optimizations for a specific target environment.
To enable this parameter, set System target file to a GRT-based system target file.
To enable parameter Code replacement libraries (Embedded Coder), set System target file to an ERT-based system target file.
None (default) | named code replacement libraries
Does not use a code replacement library.
Named code replacement libraries
Generates calls to a code replacement library for a specific platform, compiler, or standard. The list of named libraries depends on the specified system target file.
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 parameter Shared code placement to
Shared locationor you generate code for models in a model reference hierarchy:
Models that are sharing the location or are in the model hierarchy 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 (Embedded Coder)). 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 code generator reproduces code for the charts and recompiles the generated code.
You do not set parameter Shared code placement to
You change the code replacement library name or contents before regenerating code.
