Quartus

The pole frequency <number> Mhz is smaller than the loop bandwidth <number> Mhz


CAUSE: You specified internal loop parameters to define a PLL. As a result, the internal loop parameters can make the PLL unstable. This warning usually occurs when you instantiate a megafunction directly in a text file rather than using the MegaWizard Plug-In Manager command (Tools menu).
ACTION: To avoid receiving this message in the future, Altera recommends using the MegaWizard Plug-In Manager or changing the value of the internal loop parameters so that the PLL is stable.
