ID:19790 Unable to create a clock tree that satifies region constraint of "<Region constraint>" and feeds all core and periphery destinations simultaneously for clock: "<Clock name>"
CAUSE: Due to device connectivity, a clock tree that satisfies the region constraint and all core and periphery connectivity cannot be generated.
ACTION: Try changing the dimensions of the specified region or remove the Clock Region assignment to allow the Fitter to explore addtional placements for the signal.
