RE: [sv-dc] RE: new version 19 for 3398 proposal.

I think the note is informative, as it is a result of the earlier statement in the same subclause, "Table 6-7 defines the default value for data types of variables if no initializer is provided, those default values shall also apply to nets of user defined nettypes for valid data types of a net."

The note is to call attention to resultant behavior in certain cases that might surprise a user if not pointed out to him.

Since it references a statement in the same subclause, there is no need for a cross-reference either.

Regards,
Shalom

I agree with Shalom's comment about IEEE style for the formatting of notes. Notes in the IEEE standard are "informational" and not a requirement that must be followed. Is that the intent of this note? An informational note would work here if the requirement for the default value is stated elsewhere in the standard and this note is just a reminder about that, but then a cross reference to that other location would be helpful.

I think Francoise's sentence would cover that.
Note that the question would also be, I think, for a structure that contains a member of type logic (bit or vector).
In order to pass IEEE inspection, it would be easier if written as a separate paragraph, as:

"NOTE--..."

I think Shalom wanted it pointed out that it is x even if it is undriven, if it has no resolution function.

I removed the duplication.
At the end of the paragraph describing initialization of nets, I added the following note:
Note that the default value for a logic net of a user-defined nettype is x.

Is that sufficient?

Hi Francoise:

v20 still has two change sets for 7.2.2 (bottom of pg. 5 and top of pg. 6) where the first one is correct and the second is old and incorrect.

Was anything added to clarify the differences in initial values between a net and a net of a user-define nettype whose type is a single logic bit?

Thanks,
Scott

Thanks Shalom,
I uploaded version 20 which corrects these.

Minor editorial comments:

1. 6.6: "There are different kinds of net types: built-in or user-defined."
Add "two" before "different". I don't usually like adding numbers, but here I think it is better.

2. In net_declaration syntax, "delay_control" should be blue, not bolded.

3. In 28.12, delete "(Resolution of nets with user-defined nettypes)." That is not the name of subclause 6.6.7.

4. In the change to net_port_type syntax at the end of the document, the FROM part should be black, not blue. In both FROM and TO, there should be a blank, not an underscore, before "data_type_or_implicit".

Regards,
Shalom
