Description
What happens when you connect a vector to a gate terminal ?

The LRM does not say.

In the case of an input terminal, I can think of (at least) three
interpretations.

1. Use the least significant bit. (This seems to be what VCS does.)
2. Relate to it as 1 if non-zero, 0 if zero. (This seems to be what VXL and
NCV do.)
3. Expand the primitive to use all the bits, i.e., interpret
and (out, in1, in2[1:0]) as
and (out, in1, in2[1], in2[0])

Use of a vector for an inout or output terminal is also ambiguous.
