New ContributorI don't have a development board. This design targets our own custom hardware.
Regular ContributorHi,
Can you see any burn marks on your custom hardware ?
or there is any connection fail on the power cable ?

New ContributorHello.
There is nothing wrong with the board. Let me summarize again:
1. We have two FPGA designs that target the exact same board design.
2. FPGA design A supports 4 lanes of video which each run at 5Gbps. This design uses the PCIe Gen 2 x 8 core.
3. FPGA design B supports 4 lanes of video which each run at 10Gbps. This design uses the PCIe Gen 3 x 8 core.
4. The same physical board was used for all testing.
5. The PCIe Gen 2 x 8 build fails in various ways detailed earlier in this thread. I have done multiple DSE runs and all have a success rate of 30 - 40%, meaning some results work as expected. 13 out of 33 builds work.
6. The PCIe Gen 3 x 8 build always works 100%. I have done two seed sweeps of 10 and including base that means 22 builds work fine.
7. When I perform a seed sweep on the Gen 2 x 8 design using Quartus 17.1 all results work fine. 11 out of 11 work.
We need to understand what breaks the Gen 2 x 8 design in Quartus 22.3.
Thanks,
Mike
