ID:15088 Output of PLL "<name>" cannot be connected to its own clock input

CAUSE: The specified PLL drives its own clock input. The output of the PLL cannot be connected to its own clock input. 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 specified PLL does not drive itself. To avoid receiving this message in the future, Intel recommends using the MegaWizard Plug-In Manager.
