Vl-gateinst-plainarglist-blankargs

Replace any blank arguments in a gate instance with fresh wires.

Signature

(vl-gateinst-plainarglist-blankargs args nf inst) 
  → 
(mv new-args vardecls nf)

Arguments

args — Arguments to a gate instance.
    Guard (vl-plainarglist-p args).

nf — Guard (vl-namefactory-p nf).

inst — For locations of new wires.
    Guard (vl-gateinst-p inst).

Returns

new-args — With any blank arguments replaced by fresh wires.
    Type (vl-plainarglist-p new-args).

vardecls — Declaration for the new fresh wires.
    Type (vl-vardecllist-p vardecls).

nf — Type (vl-namefactory-p nf).

This is simpler than vl-modinst-plainarglist-blankargs because we do not have to consider ports: we know that every "port" of a gate exists and has size 1. We just replace any blank arguments with fresh wires of size 1.
