Figure 11-4. Power Calculator Main Window (Type View)
The top pane of the window shows information about the device family, device and the part number as it appears in
the Project Navigator. The V
core voltage, V
provide the ambient temperature and the junction temperature is calculated based on that.
Users can also enter values for airflow in Linear Feet per Minute (LFM) along with heat sink to get the junction tem-
perature.
A table in the top part of the Power Calculator summarizes the currents and power consumption associated with
each type of power supply for the device. This also takes into consideration the I/O power supplies.
In the middle pane of the window, there are three tabs:
1. Power View: The first tab is the Power View. Under this tab, the Power Calculator tool has an interactive
spreadsheet type interface with all values in terms of power consumption mW.

The first column breaks down the design in terms of clock domains. The second and third columns, which
are shaded blue in the tool, provide the DC (or static) and AC (or dynamic) power consumption, respec-
tively. 

In case of the I/Os, there are four columns that are shaded blue. These provide the DC and AC power for
I/Os for the core voltage, V

The first three rows show the Quiescent Power for V
for a blank device or a device with no resource utilization.

CC
with +5% of the nominal value (or values). The option of selecting V
CC
used for the power calculation is also listed. Users have a choice of selecting the
CC
and the I/O voltage supply, V
