Oops! I meant: for rise: time(Vhigh_slow) - time(Vlow_fast) > 1/bitrate
And for the falling V-T curves: time(Vlow_slow) - time(Vhigh_fast)

I have a few questions relating to Eckhard's observations quoted below:
1. When models have "unreasonable" lead-in time on V-T curves I guess
the solution is to uniformly (i.e. for all the corners) trim the V-T
data so as to only remain with the rise or fall data that sufficiently
captures the rise/fall time. If by doing that, however, the time range
of the resultant V-T curves [i.e. for rise: time(Vhigh_max -
time(Vlow_min) ]is greater than the bit-width, what would be the best
way to correct the model?
