100G Ethernet MAC : Transceiver configuration

Hi, I was looking at 100G low latency MAC Hard IP in stratix 10 FPGA. Here, I observed that 100G is achieved by 4 lanes of transceiver channels each running at 25Gbps. My understanding is Internall...

Hi HPB, The datasheet shown both spec for x6 and x24 but you are right, the spec is meant for CGB bonding configuration and you are not using it. Yes, as alternative, you can also refer to user guide chapter 3.9.4 Thanks. Regards, dlim

Hi @DeshiL_Intel​ ,

Is there any special skew calculation/estimation method for adjacent channels in a bank other than 3.9.4. Skew Calculations. In my view, the skew must be minimum between adjacent channels and increases with channel neighborhood. Correct me if my understanding is wrong.

With regards,

HPB

    ​Hi HPB,

    Sorry, we don't have other calculation method.

    Hi,

    I am trying to implement Soft Bonding feature to support my requirement with 20.625Gbps. I understand that I need to set TX Core FIFO mode to Interlaken to get the fifo control ports as mentioned in the Soft bonding flow in the Transceiver userguide.

    I am facing some problem while I configure L-tile native PHY in Interlaken mode. So, is it possible to share the native phy configuration required to use 100G Ethernet IP, so that I can use the same setting in my implementation?

    With regards,

    HPB
