Vl-repetitiontype-p

Representation of SystemVerilog assertion sequence repetition types, i.e., [*...], [->...], or [=...] style repetition.

See SystemVerilog-2012 Section 16.9.2.

• [* ...], [*], and [+] is called consecutive repetition
• [-> ...] is called goto repetition
• [= ...] is called nonconsecutive repetition

This is an ordinary defenum.

Function: vl-repetitiontype-p

(defun vl-repetitiontype-p (x)
  (declare (xargs :guard t))
  (or (eq x ':vl-repetition-consecutive)
      (eq x ':vl-repetition-goto)
      (eq x ':vl-repetition-nonconsecutive)))

Theorem: type-when-vl-repetitiontype-p

(defthm type-when-vl-repetitiontype-p
  (implies (vl-repetitiontype-p x)
           (if (symbolp x)
               (if (not (equal x 't))
                   (not (equal x 'nil))
                 'nil)
             'nil))
