Report Power - 2025.2 English - UG906

Generate the Power Report after routing to analyze power consumption based on the device’s operating conditions and the design’s switching rates. Power analysis requires a synthesized netlist or a placed and routed design.

Use the following instructions to prepare for power analysis:

• Use set_operating_conditions to define the device’s operating environment
• Use set_switching_activity to specify the switching behavior of the design

You can run the report power command when a synthesized design or an implemented design is open.

The Power Report estimates power consumption using inputs, such as the following:

• Thermal statistics, including junction and ambient temperature values.
  Note: You can set the junction temperature using the -junction_temp option of the set_operating_condition command. If not specified, the tool calculates it based on your design inputs.
• Board selection details, including number of board layers and board temperature
• Airflow and heatsink profile information
• FPGA current requirements by power supply source
• Power distribution analysis to support power-saving strategies
• Simulation activity files to improve power estimation accuracy
