    Yes. We are still struggling with this thermal issue. We have checked all VCC power supplies to the Cyclone 10. They are all within the specific ranges and there is no big change with the temperature increasing (less than 60mV). We have used Toolkit to test the PMA layer of the transceiver. The result is that there is no bit error under 65C (our problem occurs usually at 64C and below) .

    We don't have any obvious clue to fix it now. Any further suggestions are definitely welcome!
