Connecting ChipWhisperer-lite to Nexys Video Artix-7 FPGA: Trainer Board

Hello Guys!
I’m trying to connect my Nexys Video Artix-7 FPGA Trainer Board to ChipWhisperer, but it seems that I’m missing the 20-pin connector and the SAM port on the FPGA. Is there a way to bypass this using a converter, or perhaps I should consider changing the ChipWhisperer?



That looks to be a third party development board, so the lack of interface to ChipWhisperer is to be expected. If you do want to try doing power analysis on this board, you could route out the correct signals (clock, trigger, etc.) to one of the IO headers, connect them to the correct pins on the CW 20-pin and use an EM probe instead of a shunt resistor. That board looks like it has an adjustable IO voltage that you can set to 3.3V (like ChipWhisperer uses), which would make interfacing with the ChipWhisperer easier, though I’d be very careful that the IO voltages match to avoid damaging either board.
