Input pin <name> feeds inclk0 port of <number> fast PLLs -- some inclk0 ports will be routed via global clocks, which may reduce performance


CAUSE: The specified input pin feeds the inclk0 port of several fast PLLs. Due to device constraints, some of the inclk0 ports will be routed via the global clocks, which may reduce performance.
ACTION: No action required. To avoid receiving this message in the future, Altera recommends using the MegaWizard Plug-In Manager (Tools menu) to instantiate the altpll megafunction, rather than editing the text file manually.
