the Excel-based PowerPlay Early Power Estimator spreadsheet calculates
the power estimation and then provides a current (I CC ) and power (P)
estimation.
You can use the PowerPlay Early Power Estimator to estimate power at any
stage of the design process; however, Altera recommends that you use the
PowerPlay Power Analyzer, rather than the PowerPlay Early Power
Estimator, after the design is complete in order to obtain the most accurate
power analysis.
If you use the PowerPlay Early Power Estimator before you start your
design, you can specify device resources, operating frequency, toggle rates,
and other parameters. If you use it after you have created a design, you can
compile the design in the Quartus II software and then use the Generate
Power Play Early Power Estimator File command on the Project menu to
generate a power estimation file, which is a text-based file named <revision
name> _early_pwr.csv that contains power information for the current
device and design. You can then import this power estimation file into the
PowerPlay Early Power Estimator.
!
Using Early Power Estimations
Power calculations that are provided by the PowerPlay Early Power Estimator should
be used only as an estimation of power, not as a specification. Be sure to verify the
actual I CC during device operation, because this measurement is sensitive to the
actual device design and the environmental operating conditions.
