RE: [sv-bc] .name, .* implicit port connections

  

I agree with your interpretation. The implicit net declaration is why we
have define before use rules for nets.

Subject: [sv-bc] .name, .* implicit port connections

 

Hi,

Regarding .name and .* port connections, I have a question.

These forms do not create implicit declarations.

I want to ask about a few cases:

 

Case 0:

mod1 mod1(.a(a));

wire a;

This does not work because the mod1 instantiation implicitly declares a,
and the explicit declaration becomes a duplicate declaration.

 

Case 1:

mod1 mod1 ( .a(a) );

mod2 mod2 ( .a);

This should work because the mod1 instantiation implicitly declares a.

 

Case 2:

mod1 mod1 (.a);

wire a;

This does not work because a is not yet declared when the mod1
instantiation is encountered?

 

Case 3:

mod1 mod1(.a);

mod2 mod2(.a(a));

This does not work because a is not yet declared when the mod1
instantiation is encountered?

 

Have I got this right?

 

Thanks,

Shalom
