    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,


Thank you for reaching out Intel FPGA Community.


Can you share the design for me to reproduce it from my side?

I need to confirm first if this is a bug or not.


You can choose to share it directly or through email. Please let me know.


Regards,

Aqid

    Hi Aqid

    my OS is : CentOS Linux release 7.9.2009 (Core)

    and I check fpll lock status by signal_tap stp1.stp

    the signal name in stp is " isp_fpga_clk_locked "

    Thanks
