[sv-bc] RE: [sv-ec] Is string valid data type for 'foreach' array

Yes. The foreach should iterate over a string variable. In this respect,
a string can be considered a dynamic array of byte's.

Subject: [sv-ec] Is string valid data type for 'foreach' array

 

Hi,
SV 1800-2008 draft LRM defines 'foreach' array as follows:
12.7.3 The foreach loop
The foreach-loop construct specifies iteration over the elements of an
array. Its argument is an identifier that designates any type of array
followed by a comma-separated list of loop variables enclosed in square
brack-ets.

Is 'string' type allowed as array. Is the following case valid?
module top;
    string s;
    initial begin
        foreach (s[i]) begin
        end
    end
endmodule
