Hello, YYLau,
 
It is strongly recommended to check IBIS files using ibischk4.  Ibischk4 has
improved checks for time correlation and DC endpoint checking of the V-t
tables.  These checks were NOT added to ibischk3.
 
Best regards,
Lynne

Subject: [IBIS-Users] Rising and Falling Waveform


Dear ALL,
 
 
Regarding these 2 waveforms, is there the starting point (rising) and ending
point (falling) should be '0' or nearly '0' ?
 
But I got 1 model with these 2 point far away from '0', and it still pass
the ibischk3. 
 
So, do the model wrong or correct? And what will cause the points not start
or end at '0'?
