Greg,
IBIS model is already done. This is the question from the customer. I am not able to understand what he means telling that he needs to simulate data lines in which ibis model need to be tri stated.

Girija

Girija,

IBIS uses the following syntax to identify a tri-state model:

Model_type      3-state

Are you making a new IBIS model or using one that's already made?  The IBIS community has free tools available for making IBIS models.  If you are new to IBIS, I recommend reading the original IBIS 1.1 specification and the Cookbook.
