RE: [sv-bc] .name and .*

Dave,

That is not completely correct.

12.1.2 says,

"When a list of port connections is given using the ordered port
connection method, the first element in the list shall connect to the
first port declared in the module, the second to the second port, and so
on. See 12.3 for a more detailed discussion of ports and port connection
rules.

A connection can be a simple reference to a variable or a net
identifier, an expression, or a blank. An expression can be used for
supplying a value to a module input port. A blank port connection shall
represent the situation where the port is not to be connected.

When connecting ports by name, an unconnected port can be indicated
either by omitting it in the port list or by providing no expression in
the parentheses [i.e., .port_name ()]."

The end of the 2nd paragraph talks about a blank port connected when
connecting my order. I understand that to mean that the port connection
list contains two consecutive commas, with a blank connection in the
middle.

The 3rd paragraph explicitly mentions omitting a name port connection.

That leaves only leaving off a port at the end of an ordered port list.

But the subject is more or less covered in 1364.

Shalom
