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.

1 The PowerPlay early power estimator spreadsheets for Stratix,

Stratix GX, and Cyclone devices provide a current (I

) and

power (P) estimation based on typical conditions (room

temperature and nominal V
