Altera offers two ways to calculate power for a design: the Excel-based PowerPlay
early power estimator power calculator and the Quartus II PowerPlay power analyzer
feature.
The interactive Excel-based PowerPlay Early Power Estimator is typically used prior
to designing the FPGA in order to get an estimate of 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 power analyzer can apply a
combination of user-entered, simulation-derived and estimated signal activities
which, combined with detailed circuit models, can yield very accurate power
estimates.
In both cases, these calculations should only be used as an estimation of power, not as
a specification.
