RE: [IBIS-Users] Differential LVDS Model DC Level Mismatch

Andy,
 
Could you describe how the data was generated?
For one, I didn't see any attachment, but it
would be a little easier if you would summarize
it rather than expect everybody to read through
the setup code to figure it out...
 
Thanks,
 
Arpad

		Thanks Abdulrahman.
		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.

			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
