ALTPLL megafunction: Warning (15567): Can't achieve requested Medium bandwidth type; current PLL requires a bandwidth value of between 0.500 Mhz and 2.000 Mhz -- achieved bandwidth of 1.98 MHz to 2.97 MHz - ALTPLL megafunction: Warning (15567): Can't achieve requested Medium bandwidth type; current PLL requires a bandwidth value of between 0.500 Mhz and 2.000 Mhz -- achieved bandwidth of 1.98 MHz to 2.97 MHz Description On the Bandwidth/SS page of the Parameter Setting tab of the ALTPLL MegaWizard Plug-In Manager, if you select Auto under How would you like to specify the bandwidth setting? , during compilation the Quartus II software might generate a message similar to the following: Warning (15567): Can't achieve requested Medium bandwidth type; current PLL requires a bandwidth value of between 0.500 Mhz and 2.000 Mhz -- achieved bandwidth of 1.98 MHz to 2.97 MHz. The Quartus II software generates this message even though you did not request a Medium bandwidth type. Resolution You may safely ignore this message.
