HI,

Based on your description, looks like you are looking for feature support as highlighted in 40GBASE-CR4/KR4 as shown in attached Ethernet wiki page.

  • It also mentioned about support for Clause 72 and Clause 73 which is covered by Intel 40G IP

For Intel FPGA 40G Ethernet IP, we do support CR4 or KR4 setting selection that you can choose in the IP GUI. Pls checkout below 40G IP user guide for more detail.

Thanks.

Regards,

dlim

    Dear dlim,

    thank you for your answer. If the breakout is supported, how I can select which one among the 4 SFP+ should deliver the packet?

    I don't see any input in the Avalon-ST TX Datapath that can I use for this purpose.

    BR,
