When power estimation is completed by the PDM, the Vitis™ or Vivado® tools design should be properly constrained using Power Constraints. The following are considered the minimum requirements:
-
set_operating_conditions -design_power_budget <Power in Watts> -
set_operating_conditions -process maximum -
set_operating_conditions -ambient_temp <Max Supported by Application> -
set_operating_conditions -thetaja <Increase in Tj for every W dissipated C/W>
Tip: When constraining the Vivado tools design, the design power budget should be the K26 SOM power
estimate and not the
Kria™
K26 SOM 5V power
estimate. Unlike PDM, Vivado report_power does not
estimate the on-board components power.
