Agilex 7 E-Tile 100G Ethernet Bringup Issue

Hi Zying,

Thanks for your reply!

So it turned out that the IXIA instrument we were using had FEC enabled by default. This was not easy to see or understand since the license for IXIA that we have does not include any Layer0/Layer1 functionality, but only Layer2 configuration. So I just made a guess that maybe the FEC is enabled by default, reconfigured my E-Tile Hard IP for Ethernet and E-Tile CPRI PHY Intel® FPGA IP to enable FEC and tried and the link came up. This also explains why my FPGA-to-FPGA connection came up fine, but not the FPGA-to-IXIA connection.

Maybe it's industry standard to always have FEC enabled on your 100G Ethernet link, but at least I was not aware of this.

Thanks for your support, and I'll be back with new posts if questions arise!

Best Regards,
Viktor
