Specify a code replacement library that the code generator uses when producing code for a model.
Category: Code Generation > Interface
Default:
None
NoneDoes not use a code replacement library.
Named code replacement
librariesGenerates calls to a specific platform, compiler, or standards code replacement library. The list of named libraries depends on 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 location or 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). 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.
You change the code replacement library name or contents before regenerating code.
This parameter appears only for GRT-based targets. For ERT-based targets use the Code replacement libraries parameter.
