RE: [sv-ec] Upward referencing rules question

I think you mean, "Because a1 is visible as a scope name ...".

	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.

	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

	 

	DANiel
