Hi @zdzlin,


Thanks for reaching out to us.

Within the Stratix 10 Device Family, there are several device variants, including the Stratix 10 GX, Stratix 10 DX, and others. Given your requirement to support PCIe Gen 4.0, I believe you are targeting Stratix 10 DX FPGA. Each variant in the device family has slight feature differences from the others.


For the Stratix 10 DX 2800 FPGA, it comprises 4 P-Tiles. For each P-Tile, the P-Tile Avalon Streaming IP for PCIe can support Gen4 x8/x8 Endpoint configuration. That means it can support up to 8 EPs in total.

Following this, you would need to install Quartus® Prime Pro Edition Design Software to generate the PCIe IP and configure it according to your requirements.

For further information about the boards that match your requirements, please reach out to the Altera® Products local distributor or the sales team.
