Manually Entering Information
You can manually enter values into the PowerPlay early power estimator
in the appropriate section. White, unshaded cells are input cells and may

resource information from the Quartus II software power estimation file
into the PowerPlay early power estimator. Importing a file saves you time
and effort otherwise spent manually entering information into the

the values after importing a file.
To generate the power estimation file, you must first compile your design
in the Quartus II software. After compiling the design, click Generate
