Zedboard power consumption

Question

I'm now working on a project about AES Hardware Trojan performance based on Zedboard FPGAs, and I need the exact data of the power consumption of the FPGA while it's running my AES algorithm. How can I get it?

Thanks!

Hello Allen,

I don't know of a way to monitor the ZedBoard power consumption 'directly'. Per the ZedBoard Users Guide:

A 10mΩ, 1W current sense resistor exists in series with the 12V input power supply. Header J21 straddles this resistor to measure the voltage across this resistor for calculating ZedBoard power. Power is the measured voltage squared divided by the 10mΩ resistance.

This jumper is not connected to the Zynq device for direct monitoring. You might be able to use the connection to create a monitor circuit. If you want to measure rail by rail you would need to remove the individual output inductors and supply power externally.
