Stratix 10 SX Low Latency 40G Ethernet IP

I am attempting to use the Low Latency 40G Ethernet IP in a 1SX280HN2F43I2LPAS chip using Quartus 20.4 Pro. I am unable to get the tx_lanes_stable signal to go high or establish a link through an opt...

Hi MBarn13,


The reasons that might cause tx_lanes_stable unable go high are as below:

  1. soft_tx_rst, tx_rst_n : Resets the IP core in the TX direction. Resets the TX PCS and TX MAC. This reset leads to deassertion of the tx_lanes_stable output signal.
  2. sys_rst, csr_rst_n : Resets the IP core. Resets the TX and RX MACs, PCS and transceivers. Note: csr_rst_n resets the Control and Status registers, except the statistics counters. sys_rst does not reset any Control and Status registers. This reset leads to the deassertion of the tx_lanes_stable and rx_pcs_ready output signals.


Best regards,
