Component-Based Modeling

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 typically use a combination of Simulink^® model components.

For an overview of when to use different componentization techniques, see Component-Based Modeling in Simulink (4 min, 28 sec).

For help defining model components, see Component-Based Modeling Guidelines.

For an example that shows bottom-up model evolution, see Basic Modeling Workflow.
