Re: [Ngspice-users] Creating inductors in ngspice

John, I would have hoped that either designation would be universally
accepted, but I had read and had also been informed that ngspice
expects node 0, so for spice simulation, instead of using the KiCad GND
symbol, the pspice library node 0 symbol should be used. Well, if
ngspice accepts "GND" as node 0, then either symbol ought to work. I
just put this to the test by changing the node 0 symbol on the voltage
source to the GND symbol and the simulation still worked as normal,
which would seem to prove your point that either designation is
acceptable. I guess sticking with node 0 probably makes sense for
backwards compatibility or compatibility with spice engines that
perhaps don't accept "GND". As it happens, that was not the issue here,
but an interesting observation nonetheless.
