I am planning to purchase the CW305 Artix FPGA Board in order to attack the AES with proposed method as demonstrated in the GitHub repository of yours. At the first place I was thinking to perform power measurements (SCA) utilizing the ChipWhisperer Lite and then also using a typical/conventional oscilloscope. I believe that both 7A35 and 7A100 FPGA parts perform decent for the suggest ECC implementation. So I was wondering if the selection of the shunt and capacitor is going to have such a big impact on my measurements? In other words, are my measurements going to be that noisy due to the resistor selection? I would be truly grateful if you could give some piece of advice.
Thank you in advance.
