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 download the files you shared and programmed it with Quartus 15.0. The DisplayPort input signal was created on my laptop with a USB C to DisplayPort converter. After programming the SOF file my laptop just freeze and the only way to resolve it was to disconnect the DisplayPort. So I found another computer with native DisplayPort output and finally I got dissent MSA log (see attached txt file). I also print the vesion in the attached file.

However I still get no image on the DP Tx output display.

Please advise if this looks like Hardware issue?

I'm trying to purchase a new Arria V SK but since this board was discontinued it is hard to find. we can purchase the Arria V Development kit, do you think I can use it in the same manner? how much extra work is the porting from SK to the DK?

thanks

Ariel

    Hi,
    The next step is to port our design and run it on the Arria V starter kit and check the msa log. I assume I'll need to add some Nios 2 components to our design. Hope you can support me with this action. Another idea is to output the msa failure signal and check if it fails after sometime with SignalTap or actual oscilloscope.
    I wonder if the bug you found on the 15.0 design example may appear on our design as well and even may be the root case to the failure we have?
    Thanks
