  5. You can Preview Structural Changes in the Design Hierarchy .

  6. Press the Connect button. The Refactor Connect dialog pops-up. Here you can tune the port and signal names, as well as other refactoring parameters.

  8. Press the OK button in order to perform the changes.

Note 1: At any time you can change the connection output or input. Pick the direction using the radio buttons, select another instance, then right click Connect Input/Output.
