The second and third columns, which are shaded blue in the tool, provide the DC (or static) and AC (or dynamic)
power consumption, respectively.
In case of the I/O, there are four columns that are shaded blue. These provide the DC and AC power for I/Os for the
core voltage, VCC and the I/O voltage supply, VCCIO.
The first three rows show the Quiescent Power for VCC, VCCAUX and VCCJ.These are DC power numbers for a blank
device or device with no resource utilization.
Some of the cells are shaded yellow in the tool. These cells are editable cells and users can type in values such as
frequency, activity factors and resource utilization.
The second tab or the Report tab is the summary of the Power View. This report is in text format that provides the
details of the power consumption.
The final pane or the lower pane of the window is the log pane where users can see the log of the various opera-
tions in the Power Calculator.
