I read in one of the User Guides that GT transceivers should have their own dedicated power supplies. An upcoming design will use 3 Ultrascale+ parts and I was wondering do I need to have separate GT power supplies for each chip or can I supply just the tranceivers for all chips with one dedicated supply?
Thanks dor the help.

if there are multiple chips on the board, the MGT power supplies for each rail can be shared.
for example, MGTAVCC of all chips can be shared.
You can use XPE spreadsheet to estimate the power comsumption for each chip.
