Document Table of Contents Auto-hide Unconnected Pins

The Autohide unconnected pins of hierarchical instance option is enabled by default. However, Autohide unconnected pins of leaf instance is disabled by default, which means that the schematic viewer displays all instance ports even when the connected net is not displayed on the same schematic. This allows you to further expand the connectivity of the hanging instance port without requiring you to toggle autohide pins option first.
Note: Instance ports that are configured with default connection are hidden in the schematic viewer to improve schematic readability. For example, RAM block.

Auto-hiding unconnected pins makes the instance symbol less cluttered by hiding pins that are not connected to any net. You can disable both auto-hide unconnected pins options when you want to view all pins or obtain properties of unconnected pins.

You can disable auto-hide unconnected pins options either for all instances in the Display setting or for a particular instance using the context-sensitive menu, as shown in the following image:
