Total DC Power (Resource)
Where,

The total DC power consumption for all the resources as per the design data is the Quiescent Power in the Power
Calculator.
The AC Power, on the other hand, is governed by the following equation.

Based on the above equations, if we wish to calculate the power consumption of the slice portion, it will be as
shown below.

Power Calculations
The Power Calculator is a powerful tool which allows users to estimate power consumption at three different levels:
For first level estimation, the user provides estimates of device usage in the Power Calculator Wizard and the tool
provides a rough estimate of the power consumption.
In the second level, a more accurate approach, the user imports the actual device utilization by importing the post
place and route netlist (NCD) file.
The third and final stage brings even more accuracy to the calculation, by importing the Trace (TWR) file to popu-
late the maximum frequencies (f
post simulation (VCD) file and calculating the activity factor and toggle rates of various components.
These power calculations are discussed in detail in the following sections of this document.
