Vl-parse-genvar-declaration

Match genvar_declaration.

Signature

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

Arguments

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

Verilog-2005 and SystemVerilog-2012 agree on the following rules:

genvar_declaration ::= 'genvar' list_of_genvar_identifiers ';'
list_of_genvar_identifiers ::= genvar_identifier { ',' genvar_identifier }
genvar_identifier ::= identifier
