The best way of assigning different characteristics to a pin in an IBIS model is using the [Model Selector] feature in IBIS. This lets the use select the various voltage, slew rates of drive strength available for a particular buffer in their application. It is possible to construct IBIS models that are developed for a specific voltage, etc. which makes the users job easier but then the model creator has to develop multiple models and this can get out of hand quickly with some parts. We have done this both ways depending on the characteristics of the part.

Hi all, If the buffers of a compenent work in 2.5V and 3.3V applications, How must I specify the different applications in the IBIS model? Must I specify by means of separated components? or Must I specify by means of [model selector] keyword?
