[IBIS] Subtracting "Lead-in" Offset from V-t curves

Hi,

I have a question concerning the offset on V-t curves. I realize that most
simulators (e.g. Hyperlynx) have the option of automatically stripping the
"lead-in" offset.

However, if I do want to subtract the offset manually, is it necessary to
subtract the same offset amount to all of the rising/falling waveform
tables?

What is the effect of subtracting different offset amounts such that all the
waveforms rise/fall at the same point in time? Will this incorrectly model
the input to output delay of the buffer?

Thanks,

David
