The board is the Agilex 7 FPGA F-Series Transceiver-Soc Development Kit: https://www.intel.com/content/www/us/en/products/details/fpga/development-kits/agilex/si-agf014.html There is not a single, standard agilex-socdk board. There are currently three variants. In addition to the F-Series socdk, there are I-Series and M-Series devkits: https://www.intel.com/content/www/us/en/products/details/fpga/development-kits/agilex/si-agi027.html https://www.intel.com/content/www/us/en/products/details/fpga/development-kits/agilex/agm039.html > > But then, are they attached or you just creat the same board with > different configuration? The PCIe Root Port does involve a different FPGA configuration, but depending on the board, daughter cards and possibly cables are also involved. > > Best regards, > Krzysztof > > Thanks for the feedback, Matthew Gerlach
