WEBENCH power architect can also help design a power solution for FPGAs. Each Xilinx 7 Series FPGA is loaded into the WEBENCH database. Simply choose which FPGA is to be powered, and then choose which rails need to be powered. The current estimation is based on a worse-case model so the selected power supply will work under all operating conditions. All voltage rail requirements by each FPGA are shown here in the table. The designer can also add additional loads to power other circuits in the system. Simply click on the “add loads” icon, and an additional voltage rail will be added to the power architecture scheme. WEBENCH Power Architect supports Low Drop Out Regulators, power modules, DC/DC controllers with external FETs, and DC/DC converters with integrated FETs, depending on the preferences of the designer.
