I confirm that circuits like this can be well examined with a circuit simulator. Some points should be however considered:
- SPICE is modelling with typical component parameters, e.g. transistor current gain can vary over a larer range. If you circuit is sensitive against current gain variations, you should also test with marginal (minimal, maximal) current gain.
- SPICE models usually don't include maximum ratings and self-heating of components .
A possible way is to compare simulation with measured waveforms and find out what's different.
