Inputs The following sections of the user guide explain what values you need to
enter for each section of the PowerPlay Early Power Estimator
spreadsheet. The different Excel worksheets of the PowerPlay Early
Power Estimator spreadsheet are referred to as sections. Sections in the
PowerPlay Early Power Estimator spreadsheet calculate power
representing architectural features of the device, such as clocks, RAM
blocks, or embedded multiplier blocks.
Main Input Parameters
Different Cyclone II devices consume different amounts of power for the
same design. The larger the device, the more power it will consume
because of the larger die and longer interconnects in the device.
In the Main section, you must enter the following parameters for the
device and design:
■ Device
■ Package
■ Temperature grade
■ Power characteristics
■ Ambient temperature
■ Airflow
■ Heat sink used
■ Custom heat sink information
■ Board thermal model
■ Custom board thermal model information
■ Board temperature
