20.3.13 SmartPower Calculation Equations

SmartPower calculates the static power and the dynamic power of your design, for given operating conditions and operating modes:

Static Power: This value is a summation of the static power consumed by each element of the design. SmartPower provides a static power consumption of the array. This value is die-dependent. This value is also a function of the operating mode. For some families, SmartPower also considers a static power contribution per I/O bank. For specific I/O technologies like voltage referenced I/Os or differential I/Os, SmartPower also considers a static power contribution per I/O.

Dynamic Power: This value is a summation of the dynamic power consumed by each element of the design (nets, modules, I/Os, RAMs, FIFOs, PLLs, etc.).

Operating Conditions: SmartPower calculates power consumption in Worst, Typical, or Best operating conditions. SmartPower uses the following as general guidelines:

• It applies a voltage derating to dynamic power contributions. Higher voltage typically leads to higher power consumption.
• It applies a temperature derating to static power contributions. Higher temperature typically leads to higher power consumption.

• It applies no radiation derating.

Operating Modes: SmartPower calculates power consumption in Active, Static, Flash*Freeze, Sleep, and Shutdown operating modes, when applicable for your design.
