Kintex UP 100G Ethernet ip + GT ip

Hello,

I have a home made card woth a QSFP28 (100Gb) .

I used the 100G Ethernet IP (include GT subcore in core) ( to connect my card with a commercial NIC card.

Everything works well ( Rx-aligned , transfer data,......)

I want to split the 100G Ethernet IP (include GT subcore in example design) to have more control to the GT core (PRBS, PCSreset,....)

I follow the example design to implement the 100G + GT IP cores. It seems that clocks are ok, but the 100G never get the rx_aligned signal at '1'??

nb: (I can transmit data over the link , but I receive nothing, rx_aligned all the time '0')

Any idea?


Thanks

Dominique
