[IBIS-Users] question on including package models in IBIS file

From: CW - Doran David <davidd_at_.....>
Date: Thu May 12 2005 - 11:09:06 PDT
Below is a model for IVDS receiver containing a package 
model which I'm not sure makes sense to include.

In general, we have not included package in the ibis models because
packages differ from project to project.  If I include the package
model in IBIS, I worry that it makes the model specific to one design.

However, it seems that the package model is only under the 
component section and is only for that component, not for 
the LVDS models "LV16TR1P" and "LV16TR1N".

So perhaps it's OK to keep the package model inside this 
LVDS buffer since it's really associated with a component
"DDP3" rather than my LVDS models.

Please let me know ant comments or suggestions how this is 
generally handled - whether or not to include package model
in all IBIS models.

Thanks!
