After the board design is fixed, you must ensure that the design stays within
the constraints identified for power, power delivery, timing, and pinout to ensure the
design meets your requirements. At a minimum, Xilinx
recommends constraining the design for total power and providing maximum ambient and
Theta Ja for the most accurate estimation. Xilinx
allows you to constrain both the device power and the power delivery solution by
combining the power supplies that are connected to the same regulator and specifying the
maximum current for the regulator. You can use report_power
to check whether any supplies are overutilized. For more
information, see the
Vivado
Design Suite User Guide: Power Analysis and Optimization
(UG907).
Following are examples of device power constraints:
set_operating_conditions -process maximum
set_operating_conditions -ambient_temp 40
set_operating_conditions -thetaja 1.5
set_operating_conditions -design_power_budget 10.2
