Support The PowerPlay Early Power Estimator User Guide provides full support for
the target Altera device families listed in
Table 1–2 .
General
Description As designs grow larger and processes continue to shrink, power becomes
an increasing concern. PCB designers need an accurate estimate of the
amount of power the device consumes to develop an appropriate power
budget, and to design the power supplies, the voltage regulators, the heat
sink, and the cooling system. You can estimate a Stratix
® , Stratix GX, or
Cyclone ™ device’s power using the Microsoft Excel-based PowerPlay
early power estimator available from the Altera web site or the
simulation-based power estimation feature in the Quartus
® II software.
You need to enter the device resources, operating frequency, toggle rates,
and other parameters in the PowerPlay early power estimator.

The PowerPlay early power estimator spreadsheets for Stratix,
Stratix GX, and Cyclone devices provide a current (I
CC
) and
power (P) estimation based on typical conditions (room
temperature and nominal V
CC
).
