RE: [IBIS-Users] Maximum current flowing in Clamp data

YY,
 
Assuming that your voltage sweep range is reasonable, you may wish to
check with your design team first, regarding how they model diodes.
Diodes in some process models can be too idealized; this could easily
result in massive currents at relatively low voltages.  Fixing the diode
model before the data is generated would be likely be preferable to (and
easier than) adjusting the IBIS tables after extraction.

Subject: [IBIS-Users] Maximum current flowing in Clamp data


Hi ALL,
 
 
Recently, my model having this maximum current flow at the GND clamp
data. The value reach 
-7A.
 
I think off manually modified these data (at the portion of negative
supply voltage range) to a smaller value. So , it won't exceed the max
output short current data in data sheet.
 
How do you think? PLease comment.
 
Thanks
