Work out fpga power estimate instantly with clear inputs, formula shown and shareable results.
FPGA dynamic power scales with used resources, clock frequency and toggle rate, following the same C V squared f relation as any CMOS logic. Static power is substantial in large devices and is set by the part and junction temperature, not the design.
FPGA power
dynamic = resources x C x V^2 x f x toggle rate; total = dynamic + static
It is the activity factor. A design with 5% toggle rate uses less than half the dynamic power of one at 12% at the same clock frequency.
Lower the clock where possible, gate or disable unused blocks, reduce routing distance for high-toggle nets, and choose a lower-power speed grade.
