It is possible to simulate electronics with GnuCAP from Jupyter. First, you need to install a recent version of Gnucap as discussed in this GitBook. I installed Gnucap inside a Docker container derived from the Debian image.
See below some examples of the gnucap integration:
** simulation of pn junction Vds 1 0 DC +10V Vgs 2 0 DC +3V M1 1 2 0 0 nmos_enhance L=10u W=400u * model statement (Level 1 by default) .MODEL nmos_enhance nmos (kp=20u Vto=+2 lambda=0) ** output .print DC V(1) I(Vds) ** analysis .DC Vds 0V 3V 100mV
