Jesd204b interface seems to misbehave after upgrading quartus from 16 to 19

Hi,

Thanks for your update. I have taken a look into the signaltap that you shared. I can see that the rx_dev_sync_n seems to be de-asserted which trigger a new round of link initialization. The lane alignment achieved but after sometime, the rx_dev_sync_n seems to be de-asserted again. From the signaltap, I could not spot any anomaly which could lead the rx_dev_sync_n de-assertion.

It could be either an unexpected reset to the IP or the XCVR lose lock. To facilitate further debugging, would you mind to add the following signals to the SignalTap to check on RX PHY:

rx_is_lockedtoref

rx_is_lockedtodata

rx_analogreset

rx_digitalreset

rx_analogreset_stat

rx_digitalreset_stat

rx_cal_busy

Please let me know if there is any concern. Thank you.
