I have recently implemented AES on my ZedBoard and made it comunicate with the Chipwhisperer lite but I noticed an irregularity in my system. When I take power traces with H-Probe sometimes there are wierd spikes in the traces:
The abnormal case is the upper one and the normal is below him.
A picture of our setup in added above.
Additional information :
The zedboard is powered by 12V.
In the 20 pin connector the pins that are connected are:
Pin2(GND) to ZedBoard ground
Pin10(TIO1) is TX
Pin12(TIO2) is RX
Pin16(TIO4) gets trigger from zedboard
Do you have an idea what can cause this irregularity?
