@Krzysztof Herman In macOS I had to use os.environ.get("HOME") to get user directory, as root is /User and not /home like the python script wants.

@F A we do not support macOS but since it is similar to linux this kind of workaround are pretty straightforward. Happy to hear that you make it work.

@Krzysztof Herman same thing with Windows: had to change the "/home/" to "/Users/" And to get username: os.environ.get("USERNAME")

In the BJT collector voltage sweep, what might cause the negative 50uA current at collector voltage = 0 v.? On the other hand, curves on the cmos converge at 0 v drain voltage.
