Vl-gatetype-p

Representation of gate types.

We represent Verilog's gate types with the keyword symbols recognized by (vl-gatetype-p x).

This is an ordinary defenum.

Function: vl-gatetype-p

(defun vl-gatetype-p (x)
  (declare (xargs :guard t))
  (or (eq x ':vl-cmos)
      (eq x ':vl-rcmos)
      (eq x ':vl-bufif0)
      (eq x ':vl-bufif1)
      (eq x ':vl-notif0)
      (eq x ':vl-notif1)
      (eq x ':vl-nmos)
      (eq x ':vl-pmos)
      (eq x ':vl-rnmos)
      (eq x ':vl-rpmos)
      (eq x ':vl-and)
      (eq x ':vl-nand)
      (eq x ':vl-or)
      (eq x ':vl-nor)
      (eq x ':vl-xor)
      (eq x ':vl-xnor)
      (eq x ':vl-buf)
      (eq x ':vl-not)
      (eq x ':vl-tranif0)
      (eq x ':vl-tranif1)
      (eq x ':vl-rtranif1)
      (eq x ':vl-rtranif0)
      (eq x ':vl-tran)
      (eq x ':vl-rtran)
      (eq x ':vl-pulldown)
      (eq x ':vl-pullup)))

Theorem: type-when-vl-gatetype-p

  (implies (vl-gatetype-p x)

               (if (not (equal x 't))
