I recently posted a blog about videos of Teraspeed®’s Scott McMorrow explaining how he determined the materials to choose in order to achieve the best performance for a backplane system with a 25 Gbps+ operation.
Xilinx’s Xcell Daily Blog also reported on these videos, and they tell us more about the setup, including eval boards used (Xilinx VCU109) and the FPGA selected (Virtex UltraScale VU095), among other details. Check out the Xilinx blog here. I encourage you to check out Xcell Daily if you’re not familiar with it. There’s a lot of great info.
