Power Consumption

Use the following methods to estimate power for a design:

■

the Excel-based EPE

■

the Quartus II PowerPlay power analyzer feature

The interactive Excel-based EPE is used prior to designing the device to get a

magnitude estimate of the device power. The Quartus II PowerPlay power analyzer

provides better quality estimates based on the specifics of the design after

place-and-route is complete. The PowerPlay power analyzer can apply a combination

of user-entered, simulation-derived, and estimated signal activities that, combined

with detailed circuit models, can yield very accurate power estimates.

f For more information about power estimation tools, refer to the Early Power Estimator

User Guide and the PowerPlay Power Analysis chapter in volume 3 of the Quartus II

Handbook.

Switching Characteristics

This section provides performance characteristics of Cyclone IV core and periphery

blocks for commercial grade devices.

These characteristics can be designated as Preliminary or Final.

■

Preliminary characteristics are created using simulation results, process data, and

other known parameters. The upper-right hand corner of these tables show the

designation as “Preliminary”.

■

Final numbers are based on actual silicon characterization and testing. The

numbers reflect the actual performance of the device under worst-case silicon

process, voltage, and junction temperature conditions. There are no designations

on finalized tables.
