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?
