Displaying Library Links :: Working with Blocks (Using Simulink)

Using Simulink

Displaying Library Links

Simulink optionally displays an arrow in the bottom left corner of each block that represents a library link in a model.

This arrow allows you to tell at a glance whether a block represents a link to a library block or a local instance of a block. To enable display of library links, select Library Link Display from the model window's Format menu and then select either User (displays only links to user libraries) or All (displays all links).

The color of the link arrow indicates the status of the link.
