    Hi,


    I believe the Max 10 dev kit has 2 RJ45 port so technically speaking it's capable to support 2 Ethernet ports.


    Yet, you mentioned your Quartus design has some timing closure issue ? Then this could be the reason why your Ethernet traffic data transfer is corrupted.

    • We need to ensure Quartus design meet timing closure to prevent it from facing potential functionality failure.


    Thanks.

Hi dlim,

thank you for your reply. As this issue has been solved internally, you can close the case. It was not related to sdc constraints. Talking about sdc regarding RGMII DDIO, the one delivered with the devkit are really tight compared those given by the Application Note 477. I don't think it necessary.

Again, thank you dlim

Best regards,

John
