Push real values into queue using parameterized class

In reply to rakesh2learn:

If you want the child class to be parameterized with real type and queue depth of 6, then you class definition should be

 class newStack extends stack #(real, 6);

The child class definition that you have written means that the child class is being extended from the base class with it’s default parameters i.e. (int, 10)

I have re-written the code which should work fine.


class stack #(type T = int, int depth = 10);
   T Q[$:depth - 1];
   
   task push_Q(T data);
      Q.push_back(data);
   endtask
endclass

class newStack extends stack #(real, 6);
   
    rand bit [7:0] bit_val;
    real temp;

    task put_real();
        temp = $btistoreal(bit_val);
        push_Q(temp);
        $display("temp in extended class = %0p", temp);	
	$display(" queue in extended class = %0p", Q);
    endtask
endclass

module top;

   newStack  ext_stkP_h;
   initial begin
       ext_stkP_h = new;
       for (int i2=0; i2<6; i2++) begin // push 6 elements in extended class with parameterization case.
           ext_stkP_h.randomize();
	   ext_stkP_h.put_real();
	end
   end
endmodule
