ID:15509 Input pin "<name>" feeds the fbin input port of enhanced PLL "<name>" and other logic

CAUSE: The specified input pin feeds the fbin input port of the specified enhanced PLL and other logic. The input pin feeding the fbin input port should not feed any other logic. 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 input pin feeding the fbin input port of the enhanced PLL feeds no other logic.
