If you mean that IBIS applies only to packaged parts, I suppose you
could say that it doesn't apply to ASIC libraries. But that's at
least partly because until a cell is instantiated on a chip it's
not functional. In the sense that a [Model] in isolation isn't a
valid IBIS file and would fail the parser, you're right.

If, OTOH, you mean that IBIS doesn't provide a means to ship libraries
you're wrong. An IBIS model library can be provided as an include file
which can be imported by multiple package-level IBIS models quite neatly.
