ID:176116 Fast PLL <name>, or one or more differential I/O nodes driven by fast PLL <name>, locked on <name> side, but <name> fast PLL location is on <name> side of device

CAUSE: You assigned either the specified fast PLL or one or more of the differential I/O nodes it drives to a location that is locked on the specified side. However, the specified fast PLL location is on the specified side of the device. As a result, the Fitter cannot place the fast PLL.

ACTION: Change the location assignment for the fast PLL or the differential I/O nodes it drives.
