Uvm_config_db / uvm_resource_db for registering virtual interfaces

In reply to Vperrin:

First I have to correct ny Syntax:

module top
  apb_interface apb_tx_if(); // the keyword interface was wrong in this place
  apb_interface apb_rx_if();
 
initial begin
  uvm_resource_db #(virtual apb_interface) ("*", "apb_tx", apb_tx_if );
  uvm_resource_db #(virtual apb_interface) ("*", "apb_rx", apb_rx_if );

end
 
endmodule
