RE: [IBIS] Open Drain models

read the IBIS specification. 

What does it mean to have an open drain input?

Subject: [IBIS] Open Drain models

Hi Experts,
                    Can the "open_drain" pin be treated  as input or
output only ? How can it be defined it in the ibis file? I have
generated Open_drain models and now I need them as input/output type
too.

Is the following syntax correct ?
model_type        Input_Open_drain ?
model_type       Output_Open_drain ?

with best regards,
Mithlesh
