Design Model Architecture

Create independent components to share between models or teams, reduce visual complexity with model hierarchy

Simulink® facilitates component-based modeling and modular design. You can segment your model into design components and then model, simulate, and verify each component independently. You can save individual components as blocks in a library or as separate files. Team members can then work on those components in parallel.

Organizing your model into hierarchical components can improve readability, traceability, and reusability, while allowing for concurrent development and unit testing. To mimic real-life systems, define components based on self-contained system functionality.


  • Component-Based Modeling
    Learn when to use different types of model components
  • Subsystems
    Group blocks into functional subsystems, create model hierarchy
  • Custom Libraries
    Reusable libraries of blocks and subsystems
  • Model References
    Reuse models as blocks in other models
  • Variant Systems
    Create custom model versions to support different specifications, without duplication
  • Data Stores
    Define global values for multiple signals at different levels of a model
  • Composite Signals
    Use composite signals, such as buses, to group signals and reduce model complexity
