8 port 10/25G ethernet interface in Stratix 10

We have custom board made with Stratix 10 1ST085EN2F43I2LG. The board has 8 SFP28 ports the needs to talk to 10/25G ethernet devices. This board is used to test the connected devices by sending a fixed Ethernet packets and analyse the received Ethernet packets. 

The SFP ports needs to be selectable between 10G and 25G and enable/Disable RS-FEC. Also need the MAC statistics registers and PTP timestamping.

We could see two different IP cores available for this in the IP catalogue,

  1. 25G Ethernet Stratix 10 IP, and
  2. Ethernet Stratix 10 E-Tile Hard IP.

Which one is the right IP for this requirement.

    Hello,


    Your part number is 1ST085EN2F43I2LG. This is a Stratix 10 E-tile device (TX variant).


    The 25G Ethernet Intel FPGA IP supports Stratix 10 L- and H-tile devices only. Stratix 10 devices with both E- and H-tile transceivers are supported, but the IP core can only utilize the H-tile transceiver. Since your device is an E-tile TX part, this soft IP is not the right choice.


    The E-Tile Hard IP for Ethernet is the correct IP for your board. It is the hard IP designed for your E-tile device, natively supports 10G/25G dynamic reconfiguration, RS-FEC (on 25G), MAC statistics counters, PTP timestamping, and packet generation/checking, all the features your test board requires.


    Regards,
