Syntax

Vl-nettypename-p

Representation of wire (net) types, i.e., resolution function.

Note that Verilog/SystemVerilog net types like wire and wor essentially govern how multiple drivers get resolved, and are entirely distinct from the normal idea of a data type. See vl-vardecl for additional discussion.

This is an ordinary defenum.

Function: vl-nettypename-p

(defun vl-nettypename-p (x)
  (declare (xargs :guard t))
  (or (eq x ':vl-wire)
      (eq x ':vl-tri)
      (eq x ':vl-supply0)
      (eq x ':vl-supply1)
      (eq x ':vl-triand)
      (eq x ':vl-trior)
      (eq x ':vl-tri0)
      (eq x ':vl-tri1)
      (eq x ':vl-trireg)
      (eq x ':vl-uwire)
      (eq x ':vl-wand)
      (eq x ':vl-wor)))
