I'm also definitely in favour of updating the parameters. We should not include in the MSL examples that are numerically challenged. Regarding switching the simulation algorithm, unfortunately we don't have...

Regarding the first issue with `Modelica.Electrical.Analog.Examples.OpAmps.SignalGenerator`, opAmp1.out.v should not have any spikes at all. This is the result obtained with OpenModelica: ![immagine](https://github.com/user-attachments/assets/ef25bebb-da0c-44c4-a5c2-38be76f1ea58) which looks like a perfectly legitimate square wave...

I worked a bit more on the topic, here are my findings, I'm available to discuss them in another meeting next week. It is true that we are late with...

Now, disregarding homotopy, which only matters for initialization, the current opAmp model has two modes of operation - strict = true: `smooth(0, noEvent(if V0*v_in>vps then vps else if V0*v_invps then...

Summing up, my proposal for MSL 4.1.0 at the moment is the following: - the current SignalGenerator example in the MSL is **numerically unreliable** and as such should not be...

@GallLeo everything should be ready for the new results generation

The [regression report](https://www.ltx.de/download/MA/Compare_MSL_v4.1.0/Compare/Modelica/testrun_report.html) looks good now on Modelica.Blocks. @GallLeo there are three new examples in Modelica.Blocks.Examples: 1. Modelica.Blocks.Examples.DemoSignalCharacteristic 2. Modelica.Blocks.Examples.DemonstrateContinuousSignalExtrema 3. Modelica.Blocks.Examples.DemoSignalCharacteristic We should generate new reference files for them...

The LTX server reports issues on two examples with random numbers: - https://www.ltx.de/download/MA/Compare_MSL_v4.1.0/Compare/Modelica/TestcaseReports/Modelica.Blocks.Examples.Noise.ActuatorWithNoise/testcase_report.html - https://www.ltx.de/download/MA/Compare_MSL_v4.1.0/Compare/Modelica/TestcaseReports/Modelica.Blocks.Examples.Noise.DrydenContinuousTurbulence/testcase_report.html OpenModelica passes the verification with the latest supplied reference values successfully. Not sure what is...

> [@GallLeo](https://github.com/GallLeo) isn't this resolved now? If yes, pls. close It will be once it's been checked that the ReleaseNotes mention EddyCurrentBrake.
