I’ve some inner DUT indicators which I would like to make use of in my Monitor. I attempted to bind the interface after which use the digital interface in monitor however the DUT values would not mirror on my interface.

testbench_top-

bind fifo1 : i_dut.fifo_inst.fifo1_inst exp_interface m1 (.fifo_out(out_dut1));
exp_interface exp_intf();

preliminary
     start 
       uvm_config_db#(digital exp_interface)::set(null, "*", "exp_intf", exp_intf);
finish

interface file-

 interface exp_interface (
        output fifo_in,
        enter fifo_out
    );
    endinterface

In monitor I’m making an attempt to entry using-

if(exp_intf.fifo_out==1)
          $show("hello0---------------------");

however I do not see the dut worth of out_dut1 (which is tied to 1) mirrored on the interface.
