DVT VHDL IDE User Guide
Rev. 20.1.1, 21 February 2020
In order to connect two entity instances using new ports, you must specify the output instance (the signal source) and the input instance (the signal destination). New ports will be created across the design hierarchy as needed, in order to propagate the signal.
IMPORTANT NOTE: This feature is currently supported only in the Old Design Hierarchy View. To switch to/from the Old Design Hierarchy View, go to Window > Preferences > DVT and toggle Switch to Old Design Hierarchy View
Note 1: If something is wrong (ex: port name already exists) the Refactor Connect operation will give you the cause of the problem and pause. You can go back and make the necessary changes.
Note 2: You can undo the whole refactoring operation using Undo ( Ctrl+Z).
