9.1.03i Placer - "ERROR:Place:729 - Placer was unable to create ISERDES driving BUFIO, BUFR Rpm for the ISERDES component"

Description

I receive the following error even if there are no constraints applied to the design:

"ERROR:Place:729 - Placer was unable to create ISERDES driving BUFIO, BUFR Rpm for the ISERDES component <XYZ> for the following reason."

Some of the logic associated with this structure is locked. This should cause the rest of the logic to be locked. A problem was found at site DCI_X0Y7 where we must place BUFR <XXX> in order to satisfy the relative placement requirements of this logic. It is not legal to place this component in this site.

Solution

LOCing BUFIO and corresponding BUFR in the same clock region will fix this issue.
