ngspice

I have been learning about ngspice  - a circuit simulator

Circuits are defined in a text file by components and nodes.
So if you want to run ngspice on a netlist file it can be
as simple as cut and paste into a text file on your system
and then run         ngspice  sample-netlist.net          


Allaboutcircuits.com   was a resource that I used  to test a variety of models
that they described on the site.  It is a bit dated though so I have modified
a few of the netlists to work on ngspice.



I will post the modified circuits online once I figure out where.
