Clocked.Sampler.SuperSampleInterpolated possibly unwanted behaviour
Hi there, (I hope, this is the right place to post this) I have stumbled across some strange behavior in said class when trying to implement a time-discrete simulation. It seems like the integer variable "ticks" constantly is 1 greater than its intended value. This leads to a misalignment between the fraction used to calculate the interpolated output and the input. The interpolated output is therefore not as "smooth" as it should be. I tried solvers DASSL and CVODE in OpenModelica. Attached is a picture of the issue, where "Ueberabtastung_s_set" is an instance of the class.
I haven't found a proper fix for the issue. However, if I let "ticks" start at -1, I get nearly the desired behavior (the output should be offset by one step vertically). I.e.change line "Integer ticks(start=0);" to "Integer ticks(start=-1);" I attached a picture of this as well.
The proposed solution works well enough for me right now, but I wanted to report this anyway...
Best Julius
