New() constructor function overriding

SystemVerilog

Hi,
Greetings

I would like to know how new() constructor function is being overridden as it is non- virtual in nature.
Thanks in advance.

In reply to satih devrari:

You can override any method that is non-virtual. For a constructor, you just need an explicit reference to the extended class type by using an extended class variable or class type

class A;
  function new;
    $display("constructing A");
  endfunction 
endclass
class B;
  function new;
    super.new();
    $display("constructing B");
  endfunction 
endclass
...
A a_h;
B b_h;
...
b_h = new;
a_h = B::new;

b_h = new;
a_h = B::new;

plz tell the operation of a_h = B::new;

plz read section 8.8 Typed constructor calls in the IEEE 1800-2012 LRM

What is meant by overriding a non virtual method ? How can we do that?

In reply to Gouthams:
I just showed you above how a non virtual function gets overridden. Please see my course on Systemverilog OOP where I show you you can override both virtual and non-virtual methods, and use them together.

I think class B needs to be extended from class A.

It’s not a override a non-virtual method.I am doing only a constructor calling.

Thankyou for replaying…
