Calculate power of ZCU102 board

Hello all,

I have a ZCU102 kit from Xilinx. I have designed a system which has a custom ip. I would like to calculate the accurate power consumption of the board.

I have gone through Xilinx Power Estimator (XPE), power estimator in Vivado, Maxim Powertool, Xilinx Power Advantage Tool.

 

I would like to know the exact total power consumption which is the summation of the power consumed by the FPGA device, off-chip devices like DDR, SDCard, etc.

 

1. Which one will be the best method to calculate the power consumption accurately? 

2. If I am using power estimator in Vivado, I will get power consumption say X watts. If my C program in SDK run for Y seconds, can I calculate the energy consumption directly as the product of X and Y (X*Y) joules? If not any other method to calculate the energy consumption for a given time of Y seconds?

3. Is it necessary to have an OS running on Zynq to use Xilinx Power Advantage tool or can I use this tool on baremetal system as well?

There is a post which gives information on power consumption using physical methods (https://forums.xilinx.com/t5/Embedded-Processor-System-Design/power-consumption-at-the-physical-level/m-p/830112/highlight/true#M37879). But I would like to use digital methods like XPE or power estimator in Vivado or Maxim Powertool.

 

Thank you all in advance!
