ID:15501 Input pin "<name>" feeds <inclk0 or inclk1> of enhanced PLL "<name>" and the inclk port of a fast PLL -- routing inclk0 port of the fast PLL via global clocks

CAUSE: You specified the specified input pin to feed to the inclk0 or inclk1 port of the specified enhanced PLL and the inclk0 port of the fast PLL. Due to device constraints, the Quartus Prime software is routing the inclk0 port of the fast PLL via global clocks and performance can be reduced. This warning usually occurs when you instantiate a megafunction directly in a text file rather than using the MegaWizard Plug-In Manager .

ACTION: No action is required. To avoid receiving this message in the future, Intel recommends using the MegaWizard Plug-In Manager.
