Hi, I have managed to get a small design working. I have set the Native Core for 8B/10B mode and I am using the tx_datak port to put the link in Control mode or Data Mode. I am also using 8B/10B Control Groups [K28.5, K5.6] for IDLE mode. Groups [K23.7, K23.7] for Carrier Extend mode. My transceiver will connect to a Fiber Transceiver SFP+ module. I'm making progress but have a problem with the received data. In my testbench connect the transmit serial data into the receiver serial data port. I am able to transmit a 16-bit count and I am receiving the data, but I am missing some count values.

I will attach my archived design and a screen shot.

If anyone has some experience with transceivers can you please look over what I have and run an Gate Level sim.

Thanks,

joe
