Promote to Top-Level

This option is available to input/output/inout pins (scalar and bus), slices, and Bus Interfaces (BIF). It creates a top-level port and a net connecting the top-level port to the pin or slices. If a port with that name already exists, a new unique port name is created.

Note: When promoting BIF pin to top, all the BIF port members are renamed to include port's name as a prefix:
[BIF_name]_member_name
