[sv-bc] ansi interface port declarations

Hi,

I have returned to working on port declarations, particularly on integrating interface port declarations (i.e., port that is an interface, not a port of an interface), hoping we can approve something before the October 1 deadline, though I am in doubt whether I will be able to attend the September 12 meeting.

Anyway, Mantis 1619, which added default values to input net ports in ANSI style declarations changed the BNF from

ansi_port_declaration ::= [ net_port_header | interface_port_header ] port_identifier { unpacked_dimension } | ...

to

ansi_port_declaration ::= [ net_port_header | interface_port_header ] port_identifier { unpacked_dimension } [ = constant_expression ] | ...

The addition of the [= constant_expression] is appropriate for net_port_header, but does not seem so for interface_port_header. I think we should split them into two, like this:

ansi_port_declaration ::= [ net_port_header ] port_identifier { unpacked_dimension } [ = constant_expression ]
                                       | [ interface_port_header ] port_identifier { unpacked_dimension }
                                       | ...

Any comments?

Thanks,
Shalom
