It is unlikely that any FinFET foundry has released
these to anyone without a NDA, and very likely that
the models are encrypted.
That being said, you might find at least I-V curves
and maybe fmax / fT numbers that could let you fit
a model "well enough" for whatever you're about.
Since that evidently does not include having a real
foundry PDK or relationship, it probably doesn't have
any chance of getting real enough that few-%
accuracy matters one bit.
