ID:186269 Can't place <type> PLL "<name>" in PLL location <name> because Fitter fails to allocate routing resources of type <type> for PLL input clock port <name>

CAUSE: You assigned the specified fast PLL or enhanced PLL to the specified location. However, the Fitter cannot place the PLL because the specified input clock port to the PLL requires more regional or global clocks than the PLL location on the device can provide.

ACTION: Modify the design so that the specified PLL uses fewer input clock ports, or assign the PLL to a PLL location that has enough regional or global clocks for the input clock port.
