I was not aware that s2ibis would convert a spice connector model to an ibis model. Have you tried this?

These SPICE models can be used to model performance at high speed/frequencies. My question is if I was to create an IBIS model as oppposed to a SPICE model is there any limitations, for example? a) the highest frequency/shortest rise time possible b) how does it handle losses etc As I understand there is software to convert a SPICE model to IBIS format, would this be the best way to go or directly create an IBIS model from measurements?
