Measuring Power on DE2-70

Hi all, How can I measure the FPGA core and I/O power on the DE2-70 board (physically or otherwise) while my running my design?

Replace the existing resistors with appropriate low-valued resistors and then measure the voltage drop over them.

First perform a power analysis of your design using Modelsim to get a VCD file, and then the Quartus power analyzer. Then use that estimate to determine the resistor size.

Thanks Dave.

I was just wondering why would I need to replace the resistors on the board themselves? They are low-valued resistors anyway. Replacing the 0ohm R127 and R128 seem fair but RS1 and RS2?
