Agilex 7 F-Tile 200G hard IP de-feature clarification

There is a point in the Agilex 7 known issues list in UG-683584 for some silicon revisions

The F-Tile Ethernet 200G Hard IP block is de-featured and cannot beused in production devices with OPNs that have no suffix (blank) or "B" suffix

Does this mean that 200G "bonded" hard-IP is not supported in those older OPNs, such as 200GE-4 / 200GE-8 ? Or does it mean that all parts of 200G hard IP is de-featured?

For example would FEC/PCS/MAC still work in 10/25/50GE-1 configurations?

    Hello,

     

    • 200GE modes (such as 200GE-2 / 200GE-4 / 200GE-8) are de-featured on blank-suffix and “B”-suffix production silicon.
    • The restriction is tied to use of the 200G Ethernet Hard IP configuration itself.
    • It does not imply that the entire Ethernet hard block (MAC/PCS/FEC for lower rates) is unusable.

    Therefore, configurations like:

    • 10GE-1
    • 25GE-1
    • 50GE-1

    should still be usable, including their associated MAC/PCS/FEC functionality.

     

    • 200GE-4 / 200GE-8 bonded configurations →  unsupported on blank or B suffix devices.
    • 10/25/50GE-1 using MAC/FEC/PCS → Remain supported.

      Hi Paveet, 

      Thanks for the clarification. Good that the other modes are still available.

      I have been reading this a bit further, and it seems that the 200G HIP block is de-featured, but the 400G block is still enabled. So can't we do 200GE-4/8 using the 400G HIP block?
