RE: [sv-bc] nested modules under generate construct

Maybe better approach is to forbid both classes and modules under generate -
this feature is worthless. Classes and modules may use type parameters to
became a template.
What are the benefits of allowing such constructs under generate?

PS: 
Why dont allow only localparams in packages, generate blocks and compilation
scopes, and print errors for parameters?

Aha, the old "describe parameters in the local parameter subclause" trick!
 
(The idea of parameters that aren't, is a crime against humanity of
inconsistent and poor language design started by 1364-2001 and made much
worse in SV!)
 
Unfortunately, even after Mantis 1851, the LRM still does not say there that
parameters in generate blocks and compilation scopes are local parameters.
Even in 6.20.4, the wording should have been "shall be synonyms". I'll file
a Mantis issue on that.
 
Going back to my original points:
 
I think  26.2 should be revised to include module/program/interface
declarations and timeunits declarations in the list of constructs that may
not appear in generate blocks.
 
Regarding parameter declarations, that should be removed from the list,
since they can appear even if their meaning is like localparams. Similarly,
Clause 25 mentions parameter declarations in packages. Remember that the
forbidden construct list came from 1364, where they indeed could not appear.
 
Shalom

In the last sentence of section 6.20.4:

 

Unlike nonlocal parameters, local parameters can be declared in a generate
block, in a package, or in a

compilation-unit scope. In these contexts, the parameter keyword can be used
as a synonym for the

localparam keyword.

Where does the LRM say that?

 

Shalom

 

Recall that within generate the 'parameter' keyword is a synonym for the
'localparam' keyword.
