Vl-parse-port-declaration-atts-2005

Verilog-2005 Only. Matches port_declaration in ansi-style port lists.

Signature

(vl-parse-port-declaration-atts-2005 &key (tokstream 'tokstream) 
                                     (config 'config)) 
 
  → 
(mv errmsg? value new-tokstream)

Arguments

config — Guard (vl-loadconfig-p config).

We force these to be complete declarations because, per Verilog-2005 Section 12.3.4, in this syntax "Each declared port provides the complete information about the port...", which strongly suggests (when paired with the description of "completely declared" ports on Page 174) that it should not be declared again.
