Subcomponents and Utilities

Modularize component models by using Simulink component-based modeling options, reuse techniques, and variants

You model a subcomponent as a subsystem, linked subsystem, or referenced model. A subcomponent exposes itself as one or more entry-points symbolically scoped to its parent component. The parent component gains access to subcomponent code by using subcomponent entry points. If the usage contexts are equivalent, for example, you configure instances to use identical hardware settings, you can create multiple instances of subcomponents. Code generated for subcomponents is not accessible to platform services.
