($urandom,$urandom)

SystemVerilog

module test;
bit [31:0] addr1;
bit [64:0] addr2;

initial begin
addr1 = $urandom();
addr2 = {$urandom(),$urandom()}; //???

$display("addr1=%0d,addr2=%0d",addr1,addr2);

end
endmodule

Here
Is addr2 work like concatenation or any other method?

Thanks,

In reply to PJ:

Not sure what your question is. $urandom is a function that returns a 32-bit value. When you concatinate two 32-bit values, you get a 64-bit value.

You are better off doing

void'(randomize(addr2));

and not worrying about how big the value is that you are randomizing.
