Re: BIRD 68.1

Adam:

The rising and falling V-T tables do not have to
start at the same time as the input stimulus, but
they have to be offset by the same amount of time.

Then the buffers should simulate in an undistorted
manner - provided that the pulse width is wide
enough to capture the whole rising and falling
waveforms. The pulse width can be reduced if
a leading edge delay time removal algorithm is
used to remove equal delays in both rising and
falling waveform sets.
