Thanks a lot @maltelenz I appreciate your support! This proves: At least this model can be compared with parameterization for periodic results, and bring chaotic results with changing one parameter....

I have investigated 10 chaotic circuits up to now: [https://github.com/AHaumer/ChaoticCircuits](https://github.com/AHaumer/ChaoticCircuits) including Lotka-Volterra, van der Pol, Lorenz, Rössler, Chua, chaotic diode (Pham2016), chaotic oscillator (Tamasevicius2005), Colpitt, Shinriki, Jerk system. Some of...

@henrikt-ma I think you are right, we always can choose a very short time span for comparison. But for me the question is what is a better comparison: Either set...

Thanks a lot @casella , my example is much more complicated. Have a look at the alias variable w: I would expect 120 rpm = 2 1/s that's not the...

Thanks for your feedback @maltelenz As far as I see the time drift should be avoided by "strict = true". Here you have a comparison between the rectangle out of...

Now I am confused. Simulation with OM also reveals a time drift between the rectangle out of the circuit and the analytic solution.  This example is just a simple...

I converted this to draft since it needs more investigation, and I'm afraid that there should be changes applied to the IdealizedOpAmpLimited - for sure not for that release. If...

Yes @HansOlsson it is an issue in the IdealizedOpAmpLimited, and this needs some more investigation. There are 3 groups of examples: 1. The OpAmps-Examples {NonInvertingAmplifier, InvertingAmplifier, DifferentialAmplifier, Adder, Subtracter, Differentiator,...

Thanks a lot @maltelenz. That's really a pity, none of the results is correct: Either we get no output of the opAmps at all, or the solution drifts away. I...

Since this issue seems to depend of event generation of the specific solver: Why not try a regularization function which is nearly linear in the middle and saturates left and...
