Output tab displays various power result files. The Output tab contains the following settings:

Output Text File
For project documentation you may want to save the power estimation results. In other circumstances you may be experimenting with different mapping, placement, and routing options to close on performance or area constraints. Saving power results for each experiment will help you select the most power-effective solution when several experiments meet your requirements.
Output XPE file (for Xilinx® Power Estimator)
This file, when selected, saves all the environment information, device usage, and design activity in a file (.xpe) which you can later import into the Xilinx Power Estimator spreadsheet. This proves quite useful when your power budget is exceeded and you don't think that software optimization features alone will be able to meet your budgets. In this case, import the current implementation results into Xilinx Power Estimator, explore different mapping, gating, folding, and other strategies, and estimate their impact on power before modifying the RTL code or rerunning the implementation. You can also compare your assumptions in the Xilinx Power Estimator spreadsheet with these synthesis results and adjust XPE where appropriate.
Output RPX file
This file saves the power report in RPX format, which can later be opened in Vivado® Integrated Design Environment (IDE) by using open_report command.
