RE: [sv-bc] Proposal to make it easier to use packages with port declarations

Brad,
 
That example is illegal.
 
You have to place the
 
  import shared_decls::*;
 
statement in $unit scope, somewhere
before the module declaration in the input stream.
 
The compiler needs to see any types etc. used in
port declarations before the ports are declared.
 
Regards,
Doug

	Following up on  http://www.eda.org/sv-bc/hm/2546.html .

	 

	Is it correct that a package "import statement affects
declarations in the scope that contains the import, regardless of the
relative order of the declarations and imports statements"?

	 

	If so, does a package import affect ANSI-style module port
declarations?  For example, 

	   module ( input [WIDTH-1:0] data, 
	            input instruction_t a, 
	            output [WIDTH-1:0] result 
	          ); 
	      import shared_decls::* // this defines WIDTH and
instruction_t used above 
	    ... 
	  endmodule
