[sv-dc] RE: Revised proposal for 3398 and response to Shalom's comments

It seems to me that the net_port_type non-terminal should be extended to include user-defined nettypes.

Today we have for non-ANSI headers:

inout_declaration ::= inout net_port_type list_of_port_identifiers
input_declaration ::=
input net_port_type list_of_port_identifiers
| input variable_port_type list_of_variable_identifiers
output_declaration ::=
output net_port_type list_of_port_identifiers
| output variable_port_type list_of_variable_port_identifiers

and for ANSI headers:

ansi_port_declaration ::=
  [ net_port_header | interface_port_header ] port_identifier { unpacked_dimension } [ = constant_expression ]
| [ variable_port_header ] port_identifier { variable_dimension } [ = constant_expression ]
| [ port_direction ] . port_identifier ( [ expression ] )

net_port_header ::= [ port_direction ] net_port_type

where

net_port_type ::= [ net_type ] data_type_or_implicit

net_type ::= supply0 | supply1 | tri | triand | trior | trireg| tri0 | tri1 | uwire| wire | wand | wor

So maybe net_port_type should be changed to

net_port_type ::=
[ net_type ] data_type_or_implicit
| net_type_identifier

Since nets with user-defined nettypes can be ports, please see whether any changes are needed in the BNF for ANSI or non-ANSI port declarations and/or in the rules in 23.2.2.3.

Thanks,
Shalom
