FPGA projects require also CPU resources for the hardware build step (so-called synthesis). Keep in mind to budget enough CPU resources in order to run synthesis jobs in addition to pure CPU resources for FPGA execution jobs. A typical synthesis job for a medium sized design runs for 10 hours binding about 50 CPU cores (because of the high memory requirements). If you plan two synthesis jobs per day on average throughout the one year project runtime, you can estimate the CPU resources for synthesis jobs as: 10 hours per synthesis x 50 cores x 2*365 synthesis per project = 365.000 core-h or rounded up to 0.4 million core-h.
