In reply to cgales:
The variable reg_name is a string and only contains the methods appropriate for a string. You can’t use a string as another type of variable.
You will need to reference the register directly, or if you want to be flexible, you can use a string-based lookup to get the register.
Maybe Same question
When I ran the below code I got failed in other tool but Questa.
module top;
string s = "test[0]";
initial begin
if(s.match(".*[\\d].*") ) $display("MATCH");
else $display("NOMATCH");
end
endmodule

I got the below message

But when I ran with other tool, then I got error.
Is this Tool specific problem?
