Integrate Native Simulink Components
Integrate Simulink® components, subsystems, reference models, multiversion
                        components
Integrate native Simulink components, such as referenced models and subsystems, into your model for performing system-level simulations. You can also integrate components created in older versions of Simulink to your current Simulink session.
To model architecture of your system, use System Composer™. You can define system composer component behavior using Simulink models to analyze and evaluate the architecture of your composition.
Topics
Integrate Subsystems, Models and Libraries in Simulink
- Choose Tools to Integrate Existing Components and MATLAB, C/C++, or Python Code into Simulink
 Select tools to integrate existing components and C/C++, MATLAB, Python code into Simulink based on your modeling requirements.
- Explore Types of Model Components
 Identify Simulink components that align with your high-level modeling requirements.
- Create and Use Referenced Subsystems in Models
 Reference, reuse, and manage subsystems stored in separate files.
- Model Reference Behavior and Capabilities
 Decide whether to reference one model in another model and how to implement this model reference.
- Use Local Solvers in Referenced Models
 Learn how local solvers work and how to configure a local solver.
Integrate Multiversion Components in Simulink
- Reference Protected Models from Third Parties
 Use a protected model that you received from a third party.
- Cross-Release Code Integration (Embedded Coder)
 Integrate generated code from previous releases with generated code from current release.
- Perform Cosimulation of Multiversion Components
 Cosimulate components referencing submodels created in previous versions of Simulink.
Define System Behavior in Architecture Models
- Compose and Analyze Systems Using Architecture Models (System Composer)
 Define architectures, add metadata, perform analyses, view component dependencies, and implement behaviors.
- Implement Component Behavior Using Simulink (System Composer)
 Associate components with behavior models in Simulink.
