Hi, Marcel:
?
In fact, it doesn't matter to add a '-' sign in time or s-domain.
It just changes the positive/negative, instead of the amplitude.

Best regards.

I think I found it. When the time-domain waveform is plotted from t=0 to t=50us, it
shows a *negative-going* exponential pulse reaching -5.037kV at 960ns. (The shape is
approximately waht your picture shows, the scale is not.) At 41us it is about -20V. I am
sure that when Simulink is told to use a sample-rate of 10ns and an accuracy of 10e-9
or better, it will show the same thing. As should LTspice.
