Power Consumption

The total power consumption of a Cyclone V device consists of the following components:
Static power—the power that the configured device consumes when powered up but no clocks are
operating.
Dynamic power— the additional power consumption of the device due to signal activity or toggling.

Dynamic Power Equation

Figure 10-1: Dynamic Power
The following equation shows how to calculate dynamic power where P is power, C is the load capacitance,
and V is the supply voltage level.
