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

One of our local engineers (Jason Woolf) pointed out to me
that the diagram does allow a "gen scope array" in a "gen
scope array". So that particular concern of mine can be
ignored.

Regards,
Jim V.

] 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.
