CFD method
The analysis method is in a stable state.
Shared with Miko and confirmed the current definitions
Current definitions:
Baseline: t_0 - 17.5 ns ~ t_0 - 15 ns (2.5ns range)
Underline: t_0 + 21.25 ns ~ t_0 + 22.5 ns (1.25 ns range)
Keep it as a main reference.
Digital CFD (dCFD) method
Studied with 3 different parameters (k, d, L)
Conclusion: Impossible to select parameters in this method.
Discussion:
dCFD method - it looks like it was used when the signal has always the same properties (amplitude, fall time, width ...).
Our case is not like that.
In this case, we have to study about this method:
Is it really used only for the constant signal?
Can dCFD method be improved if we split the signal width (fall time)?
