[sdiy] Electronics Workbench

[Grant Richter]

I used Electronics Workbench extensively in the design of the Wiard. It is
very good for testing sub-circuit section to tweek resistor values and the
like. I even modeled a complete Buchla 258 oscillator with it, and it
oscillated! You can model the audio path with op-amps and tweek the
bandwidth using the Bode plotter. I have found it an extremely useful tool
and it saves a lot of tedious calculation.

Although it can be frustrating to get a simulation to run. And current
mirrors don't seem to work?
