Why does my design that compiled successfully in a previous version of Quartus II result in a no fit with the error message "Error: Can't implement PLL ..." in Quartus II version 5.0?

Environment

  • PLL
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description The settings for Stratix® II device PLLs were updated in version 5.0 release of Quartus II. The changes reflect the
    allowable settings for the PLL from the characterization of Stratix II devices. If you get an error in Quartus II version 5.0, the chosen settings are no longer valid. Use the MegaWizard Tool to recreate the PLL with corrected settings. Contact your Altera Technical Support Representative for further assistance.
