Connecting register env

Till the previous stage we had defined and created everything required within the register environment. However which agent is responsible for driving these register transactions hadn't been defined.

class my_env extends uvm_env;
   `uvm_component_utils (my_env)
   
   my_agent       m_agent;   
   reg_env        m_reg_env;
   
   function new (string name = "my_env", uvm_component parent);
      super.new (name, parent);
   endfunction
   
   virtual function void build_phase (uvm_phase phase);
      super.build_phase (phase);
      m_agent = my_agent::type_id::create ("m_agent", this);
      m_reg_env = reg_env::type_id::create ("m_reg_env", this);
   endfunction

   virtual function void connect_phase (uvm_phase phase);
      super.connect_phase (phase);
      m_agent.m_mon.mon_ap.connect (m_reg_env.m_apb2reg_predictor.bus_in);
      m_reg_env.m_ral_model.default_map.set_sequencer (m_agent.m_seqr, m_reg_env.m_reg2apb);
   endfunction
   
endclass
