Issue with calling this.randomize function

In reply to dave_59:

Please refer the below code


class A;
 rand  bit[3:0] j;  
  
 virtual function my_function();
    this.randomize();
  endfunction 
  
  virtual function build();
    my_function();
  endfunction

endclass
 
class B extends A;
 rand   bit [7:0] x;
  
  virtual function build();
    super.build();
  endfunction
   
endclass
 
module top();
 
  B b;
  initial begin
    b=new();
    b.build();
    $display(" b %p",b);
  end
endmodule

Output

vsim -voptargs=+acc=npr

run -all

b '{j:9, x:35}

exit

In this code,though we are calling only the build function which is internally calling this.randomize(); of class A,still, the variable of class B is getting randomized. My understanding is “this” should have a scope of only class A and should not have access to class B variables.
