ID:176511 Can't place DLL "<name>" in location <name> -- can't also place DLL source PLL "<name>" in location <name> because it has location constraint <name> due to source <name>

CAUSE: The Fitter could not place the specified delay locked loop (DLL)s in the specified location, because the Fitter cannot also place its reference clock phase-locked loop (PLL) in the specified PLL location due to an incompatible location constraint on the PLL.

ACTION: It you made location assignments on the specified DLL or its reference clock PLL remove the assignments or location assignments to related nodes in the design. If this does not result in a successful fit, compile the design targeting a larger device.
