How to execute sequence from test?

In reply to UVM_LOVE:

You need to assign the value that you get for packets in your sequence.


class seq_from_test extends apb_basic_test;
  `uvm_component_utils(seq_from_test)
  
  apb_sequence  s_apb_sequence;
  
  function new(string name, uvm_component parent);
    super.new(name, parent);
  endfunction
  
  task run_phase(uvm_phase phase);
    phase.raise_objection(this, "s_apb_sequence");
    s_apb_sequence = apb_sequence::type_id::create("s_apb_sequence", this);
    if(!uvm_config_db#(int)::get(this,"","number_of_packets",s_apb_sequence.packets))
      `uvm_info(get_type_name(),"the getting of packets variable failed",UVM_LOW)
    s_apb_sequence.start(apb_environment.apb_agent.sequencer);
    phase.drop_objection(this, "s_apb_sequence");
  endtask
  
endclass
