Referenced Models

Generate code for referenced models

You can generate code for a model reference hierarchy to achieve:

Incremental code generation – generate code only if the model has changes since the code was previously generated
Incremental loading – load referenced model when it is required which speeds up model loading
Modular development – develop and maintain referenced model independently from the models that use it
Code reuse – generate reusable code from referenced model

To get started on an example on how to generate code for a referenced model, see Generate Code for Model Reference Hierarchy.

Model references have limitations including, but not limited to, data logging, state initialization, and S-functions.
Simulink Cache Files for Incremental Code Generation
Share Simulink cache files in team-based development to reduce build time and avoid unnecessary code regeneration.
Establish Data Ownership in a Model Hierarchy
In the generated code, place the definitions of global variables with the components that define them.

Specify Instance-Specific Parameter Values for Reusable Referenced Model
When you create a reusable component as a referenced model, configure block parameters to use the same value for instances of the component or a different value for each instance.
Shared Constant Parameters for Code Reuse
Share generated code for constant parameters across models.
