Hi,

I'm getting following error , can you help me on this.

function void build_phase(uvm_phase phase);
  ac_lpc_agent agent; 
  super.build_phase(phase);
   if ($cast(agent, get_parent()) && agent != null) begin
      vif = agent.vif;
   end
   else begin
     if (!uvm_config_db#(virtual ac_lpc_if)::get(this, "", "vif", vif)) begin          `uvm_fatal("ac_lpc_driver", "No virtual interface specified for this driver instance");
         end
     end
   endfunction

 

ERROR: uvm_test_top.env.driver [ac_lpc_driver] No virtual interface specified for this driver instance.
