ID:15568 Output port <name> of PLL "<name>" cannot drive a SERDES receiver or transmitter when the PLL_TYPE parameter is set to FAST

CAUSE: The specified clock ports of the specified PLL drive a SERDES receiver or transmitter. However, the clock ports cannot drive a SERDES receiver or transmitter when the PLL_TYPE parameter is set to FAST. 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 clock ports of the PLL do not drive a SERDES receiver or transmitter.
