Re: [sv-bc] Type of a concat expression

Surya,

We have pointed out to you the rules that give the width, signedness and
4-stateness of the expression, and places that imply the range. That is
all the type information necessary to determine the behavior of the type
operator used on the expression. In the example you have given, that
type information does not match what it is being compared to, so the
compare is false. A tool that evaluates it as true is noncompliant.
