ID:15053 PLL "<name>" COMPENSATE_CLOCK port <name> must feed an output pin when OPERATION_MODE is set to ZERO_DELAY_BUFFER

CAUSE: You set the OPERATION_MODE parameter of the specified PLL to ZERO_DELAY_BUFFER, but the clock output specified as the COMPENSATE_CLOCK does not feed an output pin. In this mode, the compensated clock must feed an output pin.

ACTION: Connect the compensated clock to an output pin, or choose a different clock to compensate that does feed an output pin.
