The code generator supports different types of Simulink model components to facilitate efficient and robust system development, collaboration, and verification workflows. Large-scale systems typically include a combination of these Simulink model components from which you can generate and reuse code:

During model design, you can choose to convert subsystems to referenced models. Models from which you generate reusable code potentially require special treatment. For example, the models referenced by a top model must be configured to use identical hardware settings.

For models that include variant blocks or use symbolic dimensions, the code generator produces code that includes preprocessor conditionals.
