KB: Duplicate Net Names error on Multi-Channel buses

Solution Details

The multi-channel feature is appending information to your bus name, which is not following the proper naming convention. Changing the Multi-Channel naming scheme to $RoomName_$Component allows the proper naming convention to be retained for buses as these net names are formed.

Under Project ► Project Options ► Multi- channel Tab under the Component Naming - Change the Designator Format to $RoomName_$Component and then check the connections again.
