Power Consumption
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.
