Model Components

Learn when to use different types of model components

Component-based modeling enables efficient and robust system development, facilitates collaboration, and improves verification workflows. Large-scale systems may use a combination of these model components:

  • Subsystems — Allow you to create visual or functional components within a model file

  • Linked blocks — Match their contents to a block that rarely changes in a parent library file

  • Model references — Execute referenced models as independent files that interface with their parent models

For an example that shows model evolution using model components, see Basic Modeling Workflow.
