Aria V Display Port core sometimes disconnected

Hi All We have a PCB board we designed with AMD 8860 GPU that sends DP video to Aria V Display Port core (Qsys). In some of our boards we sometimes have DP connection issues. The video signal goe...

Hi,
I managed to program the starter kit 20.1 design example with Quartus 18.2. Looks like a bug that appears sometimes.
I tried to port the design example to our board but it seems the ALMs requirements for the example design is 5% higher than our PLD resource.
29,792 / 28,300 ( 105 % ) Logic utilization (in ALMs)

Is there any way to reduce the design example a bit? We are trying to purchase a larger pld and migrate our board.
Thanks
Ariel

Hi,

I'm trying to migrate from our 5AGXMA1D4F27I5 and I get only two options in the Quartus ->migration device: 5AGXMA3D4F27I5 or 5AGXMA3D4F27C5 (both parts have no stock available)

Can I assemble another Arria V with different embedded hard IP? (see page 6#) I can migrate to 5AGXBA3D4F27C4N or 5AGXFA3D4F27C4N?
Can I compromize on Transceiver Count# or Transceiver Speed Grade and still run the example design successfuly on my board that was designed for 5AGXMA1D4F27I5?

Thanks

Ariel

    Hi,

    I created a spread sheet with all arria V with the similar package code and package type that can potentially host the design example on my board. Can you please help me filter out all the appropreate candidates PLDs?

    Thanks
