Creating Subsystems

As your model increases in size and complexity, you can simplify it by grouping blocks into subsystems. Using subsystems has these advantages:

It helps reduce the number of blocks displayed in your model window.
It allows you to keep functionally related blocks together.
It enables you to establish a hierarchical block diagram, where a Subsystem block is on one layer and the blocks that make up the subsystem are on another.

You can create a subsystem in two ways:

Add a Subsystem block to your model, then open that block and add the blocks it contains to the subsystem window.
Add the blocks that make up the subsystem, then group those blocks into a subsystem.
