Hi ,
could you please let me know why we need to mention name in super.new(name)


function new (string name);
super.new(name);

endfunction

In reply to srbeeram:

It depends on the constructor of the class you are extending from. SystemVerilog implicitly inserts a call to super.new() if you don’t put one in explicitly. However it the base class constructor has arguments without defaults, you must call super.new(supplied_arguments). For example

class base;
function new(string name="base"); // default supplied
endfunction
endclass
class ext1 extends base;
  function new (int i);
     // if no super.new, "base" is default argument
  endfunction
endclass
class ext2 extends ext1;
  function new();
    super.new(2); // must have super.new
  endfunction
endclass
