Circuit simulation

[Scott Bernardi]

The discussing on vocoders brings up another subject - circuit
simulation, so I don't have to build the whole thing to see the effects
of phase, Q, number of poles, etc. What do people use for computer
simulation (PSPICE, etc)? It would be nice to have something with a
graphical front end, but I don't want to spend much on it. I already
have a schematic capture and PCB layout program I like (from
http://www.labcenter.co.uk). For 30 pounds (about $50) their Aries and
Isis light have unlimited number of pins and the PCB layout pgm even has
an autorouter. However, no netlists unless you go to their professional
version. Its available as a trial download.
They do have a circuit simulation package also, but the "cheap" version
is too limited.
