Supply Current and Power Consumption
Altera offers two ways to estimate power for your design—the Excel-based Early Power Estimator (EPE) and the Quartus® Prime PowerPlay Power
Analyzer feature.
Use the Excel-based EPE before you start your design to estimate the supply current for your design. The EPE provides a magnitude estimate of the
device power because these currents vary greatly with the resources you use.
The Quartus Prime PowerPlay Power Analyzer provides better quality estimates based on the specifics of the design after you complete place-and-
route. The PowerPlay Power Analyzer can apply a combination of user-entered, simulation-derived, and estimated signal activities that, when
combined with detailed circuit models, yields very accurate power estimates.
