Dear ALL,
 
 
Recently, my group member done some testing on the chip. And found overshoot and undershoot in the Input pins. But this is not shown in the IBIS model data.
 
Is it that mean the model that we built is not accurate? or there were some other effect need to take in to account?
 
ANother question here : How do the model looks when there were overshoot and undershoot? Can we know this by using IBISCHK?
 
 
Thanks
