[IBIS-Users] Open drain buffer : Discrepency in IBIS model vs SPICE model simulations

From: Sandeep S K <sandeepsk_at_.....>
Date: Fri Sep 26 2008 - 06:03:56 PDT
Hi
    I am generating an IBIS model for an open drain buffer (I2C). The 
simulated waveforms match when I use a 50 ohm (which is what was used 
for V-t extraction) load connected to VCC, Whereas when a different load 
is used I see a mismatch in the waveforms. Attached are the ibis model 
and a snapshot of waveforms when 100 ohm load was used. Can you please 
suggest why.

Thanks and Regards
Sandeep
