Using the PowerPlay Early Power Estimator
Power Analysis The Main section of the PowerPlay Early Power Estimator spreadsheet
summarizes the power and current estimates for the design. The Main
section displays the total thermal power, thermal analysis, and power
supply sizing information. The accuracy of the information depends on
the information entered. The power consumed can also vary greatly
depending on the toggle rates entered. The following sections provide a
description of the results of the PowerPlay Early Power Estimator.
Figure 3–5 shows the Thermal Power, Thermal Analysis, and Power
Supply Sizing areas in the Main section.

Thermal Power
Thermal power is the power dissipated in the device. The total thermal
power is shown in W and is a sum of the thermal power of all the
resources being used in the device. The total thermal power includes the
maximum power from standby and dynamic power.
1 The total thermal power only includes the thermal component
for the I/O section and does not include the external power
dissipation, such as from voltage referenced termination
resistors.
