In a typical development process you will first perform power estimation in XPE to size the voltage supply sources, evaluate thermal power dissipation paths, and allocate the total power budget to the different blocks in the FPGA system. Later in the development cycle you will want to perform post implementation power analysis in XPower Analyzer to validate against your power and thermal goals. Instead of manually re-entering this environmental data into XPA you can export to a file and have XPA read it for your next analysis. This process exports all environment, thermal, and voltage settings which in turn helps getting realistic power estimations in XPA that can easily be compared between the two tools. For step-by-step export instructions, see Exporting XPE Results.
