5. Using the user input push buttons
6. Press the User_PB3 button to enable the output pins on the HSMC connectors J8
7. Press the User_PB3 button again to disable the outputs. LED7 turns off.
8. Set the POWER SELECT rotary switch SW6 to 7.
9. Repeat steps
The sum of power results from the two sets of I/O banks provides the total FPGA I/O
power.
For specific information about on-board measurements and the POWER SELECT
rotary switch, refer to the
To obtain power values by using a DMM, measure voltage across the sense-resistors,
R215, R218, and R214 on the board, then use the voltage measurements to calculate
power.
For best results, use a DMM with six-digit or greater accuracy.
FPGA I/O power is distributed by banks
components R218 and R214. For the I/O power calculation, use the sum of voltage
measurements across these resistors while outputs are enabled. For the FPGA core
power calculation, measure the sense resistor voltage across R215.

To obtain the power P in watts, measure the voltage across the sense resistors, V
and calculate the nominal power as follows:
