Got a request for quoting IBIS model creation, and the potential
client sent his data in .STEP file format.

I have no clue what that is.

I've made IBIS models from PWL files (which I suspect .STEP might be a
form of) and, of course, Spice files.

Any ideas?

Yep, thats a CAD interchange format.
Maybe the schematic was drawn in a 3d cad package.
