ID:15515 enable0 output port of fast PLL "<name>" must feed only enable0 input port of a SERDES receiver

CAUSE: You specified the enable0 output port of the specified fast PLL. However, enable0 output port must feed only the enable0 input port of a SERDES receiver. 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 enable0 output port of the fast PLL feeds only an enable0 input port of a SERDES receiver.
