Freeware tool for converting SPICE-to-IBIS

Hello,
Does anyone know of a free tool to convert SPICE to IBIS.
I found one, but it was developed 16 years ago and is no longer supported. While trying to use it, I encountered problems with Java.
Another option is T2B from Cadence Sigrity suite, but it isn't available as separate tool.
Thanks.

What about using a bunch of .meas commands and using those results to build the IBIS model?

Try to ask the chip manufacturer, if they don't have the model and if you really need to simulate it, I would try to find a similar component which would have model. Even if you convert it, are you going to fully trust it? I believe these two models are created based on different approaches, I am not sure how accurate the conversion can be.
I know it doesn't directly answer your questions, but maybe it can help.

The tool I mentioned allows you to create IBIS models for different components, such as MOSFETs for which, unlike BJTs, there is no default model in Altium.
Asking the chipmaker is another issue. I tried to get IBIS from Realtek for purely digital ICs, but failed: Realtek does not supply IBIS for its ICs.
