ID:177002 If <dst> is placed in the following regions, <src> cannot be routed

CAUSE: The clock was implemented as a regional clock, but the Fitter had difficulty placing all its fanout in the same region.

ACTION: If the clock drivers and fanout are locked to different regions, correct the location assignments. You could also try using a larger type of clock (for example, global instead of regional), or reducing the amount of logic driven by the clock.
