Now you can manage and run SPICE simulation within GNU Emacs using ngspice.

*Code:* https://gitlab.com/atamariya/emacs/-/blob/dev/lisp/spice-mode.el

*Details:*

*Note: *Till I figure out a better way to override compilation-error rules,
you need to apply the following patch to jump to error location via
'next-error' command.

I recall that SPICE was nonfree software, in the 1980s.
What about nowadays?  Is it free?

According Wikipedia it’s now free-software, and that since back in the 
70s:

https://en.wikipedia.org/wiki/SPICE

That recalls me that in my electronic courses in college we used a 
graphical analog and digital electronic simulation software from the 80s, 
called respectively “analog” and “diglog”, from a “chipmunk” software 
suite, and that was so old (and unupdated since so much time) it directly 
dialogued with the X server and was licensed under the GPLv1…
