ZYNQ ZC702 measurements of current
R75 is the current sense resistor for VCCINT (0.005 ohms).  It is connected to instrumentation amplifier U46.  U46 has a 4.22K gain resistor for a gain of 1 + 100/4.22 = 25 (from INA333 datasheet).  This means that the output of U46 will be 0.005 * 25 = 0.125 volts per amp through R75.  The bandwidth should be somewhere around 10 kHz.  I'm not sure if there is an easily accessible test point for that signal.  It comes out of U46 on pin 6, then through R252 and into U32.  I would recommend soldering a fine wire onto the U46 side of R252 and connecting your scope probe to that.  R252 is probably a larger target than U46 pin 6.  

R222 is part of the voltage feedback for the switching converter.  It's marked DNP on the schematic; you should leave it that way.
