Another possible reason for the error-vs-warning differentiation, on top of those already mentioned....
When a mistake is easily avoidable and/or correctable, and not the result of variations from one (simulator) implementation to another, they would be errors.
A file name error is easily and permanently fixed.
On the other hand, an "AC" mismatch depends to some degree on the interpolation algorithm used by the simulator. Also, miniscule voltage errors can sometimes cause enormous percentage differences, but shouldn't prevent the model from being used (without an expert handy to tweak the tables).
Regards,
Andy
