Re: [sv-bc] how to access an interface paramter

In http://www.eda.org/sv-bc/hm/4269.html , Paul asks whether a
hierarchical name rooted at an interface-type port reference can be used
to access parameters in the connected interface instance.  For example,

 
    module cpu(interface bus);
        var logic [bus.N-1:0] scratch;
        ...

    endmodule:cpu

 

According to the current BNF, it can't.  Yet, as pointed out in
http://www.eda.org/sv-bc/hm/3348.html, there is a backdoor way to the
get the same effect.

 

So should the back door be closed, or should the BNF add a front door? 

 

Personally, I'd prefer to add the front door.  According to Dave in
http://www.eda.org/sv-bc/hm/4282.html, this front door would be safe.

 

I was unable to open a Mantis item about this, but will do so later.
