There is no option in BitGen for Virtex to tie down unused interconnect, or save that state to an ncd file.
Why is this?
The Virtex devices have an architecture that makes it easy to tie down, so every design is always tied. Routing special tie signals or writing out other .ncd files is unnecessary.
