5.1.2. Static, Dynamic, and Standby Power

A combination of dynamic, static, and standby power determines the total power of an FPGA. However, a better understanding of the types of power can contribute to easier power optimization and improved cooling.
  • Static Power, or the leakage power, is a function of process node and temperature. FPGA resource usage has some impact on the static power, but that impact is minimal compared to the effects of temperature.
  • Dynamic Power is strictly a function of the resources used and is highly affected by their clock frequencies and toggle rates.
  • Standby Power is the power that is consumed without any FPGA activity, and is not a function of temperature. Standby power consumption cannot be reduced by optimizing the design or reducing temperatures.
Note: Static power consumption is not the same for every part. The distribution of static power across a given lot of parts is more like a bell curve, but the PTC reports the highest static power for each part, so the cooling and power system can encompass all parts.
