ID:176560 PLL input clock "<name>" feeds multiple PLLs but I/O pin "<name>" cannot use global or regional clock to feed multiple PLLs

CAUSE: The Fitter cannot assign the specified PLL input clock to the specified I/O pin. The PLL input clock feeds more than one PLL. PLL input clocks that feed more than one PLL must use global or regional clocks. However, the specified I/O pin has no access to global or regional clock signals. This message is a submessage of the message that precedes it in the Messages window and in the Messages section of the Report window.

ACTION: Assign the specified PLL input clock to a different I/O pin.
