ID:177001 There was not enough core-to-clock-driver routing for <src> to route to <dst>.

CAUSE: The specified clock driver input could not be routed from the core due to limited core-to-periphery routing. This error occurs because you placed too many clocks in the same region with limited routing, or because your design contains too many clocks for your device.

ACTION: If the clock drivers are constrained to a region, relax the constraint to allow the clock drivers to spread out and take advantage of more routing. Otherwise, change your device or reduce the number of clocks in your design.
