Description

This pcore is a combination of Xilinx Vitex-5 Embedded Tri-mode Ethernet MAC (TEMAC) and an AXI4-Stream adapter. Incoming SGMII signals from AEL2005 are received by the TEMAC and finally transformed into AXI4-Stream. The TX side follows the exact same path but in the opposite direction. Although we use "Tri-mode" MAC, due to the limitation of AEL2005, only Gigabit Ethernet mode is supported.

The Virtex-5 Embedded Tri-mode Ethernet MAC is a dual-MAC hard IP. Hence, each pore has two independent groups of buses, corresponding to each MAC.

There is one additional AXI4-Stream bus for transmitting bad_frame signal provided by Xilinx TEMAC. For more information about NetFPGA Standard IP Interfaces, please see here.
