As I know, pocv calculates cell delay using follow function:

so, question 1 : How to get the nominal delay? if the cell is a multiple inputs cell, which input slew should I use to get the cell delay?

And question 2 please see below figure:
Figure 3: Delay distributions propagate through the timing graph as independent variables

It comes from document "PrimeTime Parametric On-Chip Variation Application Note" of solvnet,
I totally have no idea about it, could somebody explain it? thanks!
