RE: [sv-ec] Upward referencing rules question

Daniel,

 

It is an error as approved by mantis 2217. Because a1 is visible as a
variable name where the reference occurs, the search does not continue
beyond the block oo.

Subject: [sv-ec] Upward referencing rules question

 

I cannot find rules for below reference in SV.I'm using reference to
a1.num in named block "oo". In this block there is object variable named
a1 but it has no "num" funcion 

The question is: Should seraching for matching function be stopped at
this level or should the search be continued into module scope - where
is "a1" instance which have "num" function.

So below case should return error, or it should compile and return "5"
in simulation?

 

 

module M;
 function integer num();
  num= 5;
 endfunction
endmodule

 

class C;
        reg r;
endclass

 

module top;
 M a1();

 

 initial begin : oo
 C a1;
 $display(a1.num());
 end
endmodule
