I’m trying to use the TVLA assessment provided by Chipwhisperer on my FPGA board. (Clone of the repo tagged as 5.1.3) They provide the PA_TVLA_1-Performing_TVLA_Testing_for_Crypto_Validation.ipynb Jupyterplaybook for that. I modified it to initialize the FPGA but the rest of the flow is identical being the capturing of the traces and analyzing them.
The code which does the analysis and errors out.

I don’t really understand what is going wrong, it seems to be some kind of parameter passing, but it is in the library itself so I’m expecting that something changed?

Answer
