Shared reconfiguration controller for 2 (separate) transceivers

    Hi Zying,

    One small question. Is it correct that when I create 2 separate transceiver instances, I need a (single) reconfig-controller with the following settings: "Number of reconfig interfaces = 4" and "Optional interface grouping = 2,2" ?

    Kind regards,

    Arno

Hi arno_va,


Can you share your .qar file here? So that I can try debug the issue from my side.


Best regards,

zying

    Dear Zying,

    Thanks for your reply. I will provide the .qar-file as soon as I'm back at work (tomorrow).

    Just to clarify about what I'm trying to accomplish: I basically want to interface a single C5G board with 2 (fiber) transceivers to 2 other C5G boards (each with a single transceiver).

    Kind regards,

    Arno

    Dear Zying,

    Here's the qar-file you requested. Hopefully it helps in resolving the issue.

    ps. the transceiver/reconfig ip instances are at the bottom of the top-level.

    Cheers,

    Arno
