Hi Kevin,
Wow, You put a lot of effort in answering my question. Thanks I really apricate it.
Even i with only two runs it saves time. The old way was to separate simulations with different ways, always checking separate simulations where exactly the same.
Or I made the same schematic in SiMetrix/Simplis. I do not know if you are familiar with this simulation software, But it is fast and I mean really, especially if it comes down to frequency response analyzing in the the time domain. Of course there is a down side to this program. Simplis has to find a periodic Operating Point. An that can be quite a challence. Thanks again
