Any ideas on this would be much appreciated...

The generation setup was attached. The buffer was disabled when generating the power/gnd clamps. Hope to get some advice.Thanks.

Andy, 

 

How did you generate the IBIS model? Pls share a little more details on how you generated may help in troubleshooting your issue. 

 

Thanks,

Subject: [POSSIBLE VIRUS:###] [IBIS-Users] Differential LVDS Model DC Level Mismatch


 

Hi,
I have generated the differential IBIS model but when it comes to doing the correlation, 
i found that the DC level for the generated IBIS model is smaller than Spice model.However,
the both wavefroms are pretty correlated in terms of their shapes. I have attached the 
screenshot of both waveforms.I am wondering what is the reason behind this? 
Could someone please shed some light in order to make the DC level correlated?
Thanks a lot.
- Andy
