Why does the E-Tile Hard IP for Ethernet Intel® FPGA IP fails to complete Auto Negotiation with Active Optical Cables? - Why does the E-Tile Hard IP for Ethernet Intel® FPGA IP fails to complete Auto Negotiation with Active Optical Cables? Description The E-Tile Hard IP for Ethernet Intel® FPGA IP does not support Auto-Negotiation, and Link Training with Active Optical Cables (AOC) as the IEEE Standard for Ethernet (IEEE 802.3) defines supports for the feature over backplanes and copper cable assemblies (Clause 73). Resolution Enable Auto-Negotiation and Link Training support for the E-Tile Hard IP for Ethernet Intel® FPGA IP only when using a backplane or copper cable as transmission medium. The E-tile Hard IP User Guide: E-Tile Hard IP for Ethernet and E-Tile CPRI PHY Intel® FPGA IPs will be updated to include detailed information.
