Subsystems

Group blocks into functional subsystems, create model hierarchy

As a model increases in size and complexity, you can simplify it by grouping blocks into subsystems. A subsystem is a set of blocks that you group into a single Subsystem block.

Using subsystems:

Establishes a hierarchical block diagram, where a Subsystem block is on one layer and the blocks that make up the subsystem are on another.
Keeps functionally related blocks together.
Helps reduce the number of blocks displayed in your model window.
Establishes an interface with inputs and outputs.

When you make a copy of a subsystem, that copy is independent of the source subsystem. To reuse the contents of a subsystem across a model or across models, consider referenced subsystems, referenced models, or subsystems linked to a block in a custom library. For more information, see Choose Among Types of Model Components.

A subsystem can be virtual or nonvirtual. A virtual subsystem provides graphical hierarchy in a model. A nonvirtual subsystem provides graphical hierarchy and executes as a unit within a model.
