General
Description

As designs grow larger and processes continue to shrink, power becomes
an increasing concern. Printed circuit board (PCB) designers need an
accurate estimate of the amount of power the device will consume to
develop an appropriate power budget, design the power supplies,
voltage regulators, heat sink and cooling system. You can calculate a
Cyclone II device’s power using the Microsoft Excel-based PowerPlay
Early Power Estimator spreadsheet available from the Altera website or
the PowerPlay power analyzer 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 spreadsheet.

This user guide explains how to use the Cyclone II PowerPlay Early
Power Estimator spreadsheet to estimate device power consumption.

These calculations should only be used as an estimation of
power, not as a specification. Be sure to verify the actual power
during device operation, as the information is sensitive to the
actual device design and the environmental operating
conditions.
