IBIS to Proprietary Simulator Model Conversion Tools

EDA Companies,

IBIS to proprietary model, conversion tools don't make sense to me. Why not
have your simulators use IBIS models directly? If your simulation tool does use
IBIS models directly (without a separate conversion utility), I would like to
know who you are.

Some of you even plan to charge outrageous (to me) amounts of money for such
conversion tools.

IBIS is the standard for exchange of information on I/O Buffers. You will need
to have IBIS capability to be a viable tool vendor in the future (at least for
signal integrity and timing analysis work). Why put an additional hurdle in the
way of your customers?

A proprietary model to IBIS conversion tool would make more sense to me than
converting in the other direction. Such a tool might be worth buying. The most
important model to IBIS conversion tool, from my perspective, is s2ibis, and I
believe it is free.

If you are one of the companies that make a variant of SPICE simulator, you
should be especially eager to provide IBIS compatibility. The use of IBIS
models will speed up your simulator and narrow the speed gap between you and
non-SPICE type simulators.

Am I missing something here? I'm aware that there are analog simulations to
which IBIS models may never be successfully applied, but for digital signal
integrity work, IBIS is the way of the future.
