waveform.
4. Vtop: the voltage value from the flat top of the waveform to the GND.
Vbase: the voltage value from the flat base of the waveform to the GND.

is the number of points being measured.
9. Overshoot: the ratio of the difference of the maximum value and top value of
the waveform to the amplitude value.
10. Preshoot: the ratio of the difference of the minimum value and base value of
the waveform to the amplitude value.
