Vivado Power Analysis - How do I get the most accurate results from report_power?

Description

How do I get the most accurate results from report_power?

Solution

To get the most accurate power analysis with report_power, provide the following:

  1. Provide very accurate thermal information (Process, Junction Temperature, & Environment Settings) (Xilinx Answer 63016)
     
  2. Provide pessimistic power supply voltages (worse-case or upper power supply voltage per rail) (Xilinx Answer 63017)
     
  3. Provide accurate clocking specifications (create_clock or create_generated_clock for all clocks) (Xilinx Answer 63018)
     
  4. Provide accurate switching activities for control sets (use the set_switching_activity command on all global/regional resets and clock enable signals) (Xilinx Answer 63019)
     
  5. Provide accurate switching activities for primary inputs (use the set_switching_activity and set_input_delay command on specific protocol or handshaking inputs and data ports) (Xilinx Answer 63020)
     
  6. Provide accurate switching activities for major components (use the 'set_switching_activity -type'  command on major components such as BRAM, DSP, etc.) (Xilinx Answer 63021)
