Voltage regulator

Ummm, no xD Sorry but inductors shorting to ground make for bad regulators

If we are talking about the damped wave trains here... I have seen this before, as many of us have. I think it is an aberration of the simulator, that occurs when current readings are very low. Or near that neighborhood. I think that an increase of accuracy, of the math in the simulator, might have an effect of reducing the faulty reading being generated. For instance, instead of computations based on 3 significant figures... increase that to 8 or 10 significant figures of accuracy. The symptom might still exist, but at a level too small to display. Accuracy in the range of 3 significant are really old school. It is "slide rule accuracy" and outdated to the extreme. Floating point math to 16 digits is not uncommon these days. This range of accuracy could have a detrimental effect on the speed of computations, however.

The same symptom can be shown without the inductor. Remove the inductor, start the SIM and inject noise by shaking. I had to shake fairly hard to get enough noise to initiate the fault.
