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

Hi, so far I think the new version is much tighter than the original.

However, I still have a problem with the following issue.

The text in 6.7 starting, "Certain restrictions apply to the data type of a net. A valid data type for a net shall be one of the following," does not say that it only applies to nets of non user-defined data types.

Regards,
Shalom

The following text in 6.7 needs to change:
"A valid data type for a net shall be one of the following:
a) A 4-state integral type, including a packed array or packed structure.
b) A fixed-size unpacked array or unpacked structure, where each element has a valid data type for a net.
The effect of this recursive definition is that a net is composed entirely of 4-state bits and is treated accordingly. In addition to a signal value, each bit of a net shall have additional strength information.
...
The default initialization value for a net shall be the value z."
.
This only applies to nets of non user-defined nettypes. Next sections 6.7.1 and 6.7.2 will define the legal datatypes for nets of user defined nettype
and their default initialization value. I added text at the end of section 6.7.2 to describe the legal data types for a net with a user-defined nettype.
