      Hi,

      no reason to apologize. Just wanted to inform that there's a previous discussion with solutions. Forum search isn't very purposeful yet. I e.g. didn't find out how to perform an explicite and conjunction of terms, can be my fault.

      Regards Frank

      Hi,

       

      I wanted to inform that this issue is still under investigation.

      May I know if you have tried the workaround and see if it works on your side?

       

      Regards,
      Aqid

        Hi. I haven't tried the workaround, and I've also noticed that sometimes an error appears that prevents the wizard from opening. Whereas in the previous Quartus Prime Lite 24.1, it works fine.

        Kind regards.

    Due to this is bug is present in PLL IP, which is used in nearly every design - it would be great to have available patch for it to not let wait the users for next release of Quartus Prime Lite/Standard editions. The releases of Quartus Prime Lite/Standard in past usually comes in autumn, which is quite long time.
