Since capacitors are linear devices, the behavior becomes linear and the solver can get through the highly nonlinear behavior zones by taking them in small …

If SPICE was doing just fine and then lands *really* close to one of these points, it may find that it can't get to the critical point without making the internal timestep too small. This is one of those "by chance" situations where changing ...

There is a lot I have yet to figure out between settling time ( pretty obvious) number of samples, FFT size and minimum step. Vary these parameters and yo can get the same circuit with .0001% distortion, or 1%.
