You can review the total on-chip power and thermal properties as well as details of the power at the resource level to determine which parts of your design contribute most to the total power. For more information, see this link in the Vivado Design Suite User Guide: Power Analysis and Optimization (UG907).
Power Tip: Review and validate
the decoupling requirement of the completed Vivado
design against the current schematic/PCB. You can generate a .xpe file from Vivado tools
report_power using the following Tcl
commands:set_operating_conditions -process maximumset_operating_conditions -ambient_temp <max Ambient requested for
application is Celsius>set_operating_conditions -thetaja <the rise in junction temperature for
every watt dissipated, obtained from thermal simulation, C/W>report_power -xpe {C:/Design_Runs/Vivado_export.xpe} -name {Any_Name}
