    Hi King22,


    Thanks for the project file. I am able to reproduce the crash so I will make a report to engineering to fix it in future release.


    As for the fpll can't unlock in Quartus 22.4, can you continue the communication in another forum that was posted by you?

    I believe that was supported by another AE in that post.


    I will close this one. Is it okay for you?


    Regards,

    Aqid

Hello,


  1. Can you share the project file with more than 4 channel for me to reproduce the Quartus crash on version 21.1?
  2. Thank you for the explanation. I will reproduce it from my side.


Regards,

Aqid
