I have posted yet another update. Fixed more bugs and stepped into
LTSpice's territory. I have added a very generic, general Pulse Width
Modulator that can be used as a building block for SMPS, there is also

SuperSpice, a very affordable Mixed-Mode
Windows Simulator with Schematic Capture,
Waveform Display, FFT's and Filter Design.
