1.2.3. Connecting the Low Latency Ethernet 10G MAC to Avalon-ST, Avalon-MM, and XGMII PHY Interfaces

After generating the synthesis file for the Low Latency Ethernet 10G MAC IP core, you can replace the existing 10GbE MAC IP core synthesis file (<user_specified_ip_filename> .v) with the newly generated Low Latency Ethernet 10G MAC synthesis file. Due to the differences in the signal names between both cores, you must make sure these signals are connected correctly to the user and PHY interfaces.

Table 3.   Differences in Signal Names for Low Latency Ethernet 10G MAC IP Core and 10GbE MAC IP CoreThis table lists the signal names in the Low Latency Ethernet 10G MAC IP core with all 64-bit MAC interface adapters enabled and its corresponding signals in the 10GbE MAC IP core.
