AN881 reference design need to be upgraded for device 1SM21CH.

Hi Sir,

​

We did a lot of experiments, e.g. to reduce the required BAR space, to rule out BIOS issues, motherboard issues, and Linux OS issues.

Yesterday we find a reference design from Terasic, that design uses "PCIe hard IP hen3x8", and it works on our platform.

But the reference design is only PCIe and on-chip SRAM.

We still need a whole system like AN881 with HBM2.

​

Therefore, we strongly doubt that the root cause is some bugs in PCIe hard IP+ gen3x16 (Quartus V19.3).

Please help to forward the information to design author, and fix the issue of AN881 reference design.

​

Thanks.​
