Hot swap between 10x10G and 4x25G versions of 100G Ethernet using hard MAC on Virtex UltraScale FPGAs—the video

The new 3.5-minute video below demonstrates the hot-swap ability of the hard, integrated 100G Ethernet MAC in Xilinx 20nm Virtex UltraScale FPGAs, which incorporate multiple hard 100G Ethernet MACs and the 30.5Gbps GTY SerDes ports needed for the job. The demo shows a Virtex UltraScale VU095 FPGA on a VCU107 Eval Board automatically switching from a 10x10G configuration to a 4x25G configuration as Xilinx Transceiver Technical Marketing Manager Martin Gilpatric first plugs a 10x10G CFP2 SR10 optical module into the board and then hot swaps that module for a 4x25G CFP2 LR4 optical module.


The test configuration in the Virtex UltraScale VU095 FPGA looks like this:

The blue MDIO block in the FPGA senses the module type and then the FPGA automatically adapts the 100G Ethernet MAC accordingly.


Here’s the video. Look closely. There’s nothing up Martins sleeves during this hot-swap demo. He’s wearing a short-sleeved shirt.




Note: The 20nm Virtex UltraScale VU095 FPGA has been shipping to Xilinx customers for nearly a year now.
