I think this isn't really an IBIS issue. It's a question to
take up with whoever makes your simulator. IBIS is a format
for models, not simulators.

My naive answer is that any simulator that handles IBIS models,
(probably) also handles SPICE models. So just use SPICE models
where appropriate, and IBIS models for those digital devices
that have them, in the same simulation.

If there is a simulator that accepts IBIS but not SPICE models,
I think I'd stay well away from it. I can't imagine that any
analog simulator would take IBIS models but not SPICE models.
