ID:15514 enable1 output port of fast PLL "<name>" must feed only the enable1 input port of a SERDES receiver or the enable0 input port of a SERDES transmitter

CAUSE: You specified the enable1 output port of the specified fast PLL. However, the enable1 output port must feed only the enable1 input port of a SERDES receiver or the enable0 input port of a SERDES transmitter. This error usually occurs when you instantiate a megafunction directly in a text file rather than using the MegaWizard Plug-In Manager .

ACTION: Modify the design so that the enable1 output port of the specified fast PLL feeds only the enable1 input port of a SERDES receiver or the enable0 input port of a SERDES transmitter.
