I agree, but you can already do that by repeating the original
voltage or current waveform with a VCVS or CCVS respectively,
across which you have a capacitor connected. The current of the
capacitor is your first derivative. However, for some unknown
reason I could not cascade this circuit to obtain 2nd derivatives
I got all kinds of numerical oscillations. Does anyone know why?
BTW: HSPICE can give you derivatives with the measure statement too.
What I wish is that they would not only give it at a requested time,
but also tell me at what time it was a certain value (like zero)...

I think that a feature to continuously measure the derivative of a nodal
voltage or current would be very useful in I/O buffer simulations.
