ID:15483 enable1 input port of the SERDES receiver atom "<name>" is driven by an invalid port -- enable1 input port must be driven by a valid enable output port of a fast PLL

CAUSE: The specified SERDES receiver atom has an enable1 input port that can be driven only by a valid enable output port of a fast PLL. 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 input port of the SERDES receiver atom has a valid source.
