I have all my files compiled well, but for simulation i have fail status because this message :  
NO HANDLE OF VIRTUAL INTERFACE IS RECEIVED

```verilog
initial begin 
            $timeformat ( -6, 3, " us", 10);
              uvm_config_db#(virtual ahb_interface) :: set(null , " uvm_root* ", " ahb_s0", ahb_s0 ) ; 
              uvm_config_db#(virtual spi_interface) :: set(null , "uvm_root*", " spi_m0", spi_m0 ) ;
            run_test() ; 
  end

```

I have this as a code, so can you propose me solution to resolve that ?

Replace “uvm\_root\*” with “\*”. Also, get rid of the spaces in your string names.

Thank you Sir,

I try to make it but i have always the same problem, so this is my last code :

```verilog
 $timeformat ( -6, 3, " us", 10);
              uvm_config_db#(virtual ahb_interface)::set(null, "*", "ahb_s0", ahb_s0);
              uvm_config_db#(virtual spi_interface)::set(null, "*", "spi_m0", spi_m0);
  run_test(); 

```

You will need to show us the code that does the config\_db::get and produces the error message.

Check the key in get() call, modify the key “vif” to “ahb\_s0”
