Vl-expr-resolved-p

Recognizes plain constant integer expressions.

Signature

(vl-expr-resolved-p x) → *

Arguments

x — Guard (vl-expr-p x).

We say an expression is resolved when it is just an atomic, integer value that is free of X/Z bits. We often expect to be able to resolve the expressions that occur in ranges like wire [3:0] foo; and in selects.
