RE: [sv-cc] Item 313: PTF 296: Generate stmts will need change made in VPI

Charles,

I believe the proposal needs to make a clearer distinction
between the "gen var" and the corresponding implicitly
defined local parameters. The "gen var"

-- belongs to the the parent scope of the generate, and
as such has a vpiFullName that does not include the
name of the "gen scope"

-- carries no value once the design has been elaborated.

Each local parameter, on the other hand,

-- belongs to one of the generated "gen scopes"

-- has the same vpiName as the "gen var"

-- has a vpiFullName that includes the name of the
"gen scope" that it belongs to.

-- has a value in the elaborated design corresponding
to the value that the "gen var" had when the "gen scope"
was elaborated.

Also, I believe generates can be nested, so that it
should be possible for a "gen scope array" to be
embedded in a "gen scope".

Also, I believe (but am not sure) that a "gen scope"
for a generate-conditional or generate-case would
be embedded directly within a parent "module" or
"gen scope", rather than in an "gen scope array".

I apologize ahead of time if I've missed some earlier
resolution, since I'm relatively new to the PTF.

Regards,
Jim Vellenga
