Cyclone 10 GX 40GBASE support

Hello, I am designing a 40GBASE application with the Cyclone 10 GX. The XCVR transceiver user guide gives limited direction to setting up the platform designer with this protocol. First, is ther...

Hi,


It's unfortunate you have build C10 GX board.

  • I google around but I don't see any 40G ethernet IP solution that offered by any of the Intel design partner house


Pls see my reply below

  1. So there is support for the 40GBASE PHY but not the MAC? Do you no of any third party MAC IP providers? We already have the board design finished for the Cyclone.
  • You have mistaken with the 40GBASE preset in NativePHY IP. The preset just helped user to enabled transceiver skeleton design to prepare to intercept with Ethernet PHY design if user decided to create one.
    • The preset doesn't turn NativePHY IP to become 40G Ethernet PHY IP that equipped with Ethernet PHY function. You probably miss out NOTE 6 at the end of the table 3 that you show me
    • NOTE 6 - Link training, auto speed negotiation and sequencer functions are not included in the Native PHY IP. The user would have to create soft logic to implement these functions when using Native PHY IP.
    • In short, The NativePHY IP doesn't contain Ethernet PHY function
  1. Can the Arria IP be leveraged for us to create our own MAC or will this have to be done from scratch?
  • Sorry to say so but unfortunately you will have to build your own 40G Ethernet PHY + MAC IP solution if you decided to stick with Cyclone 10 GX device


Thanks.
