各位：
   最近正在使用UVM搭建仿真平台，遇到一个改变default_sequence的问题。嗯，先上代码:

class wdma_base_test extends uvm_test;
wdma_tb       tb0;
vsequencer  vsqr;
vi_config vdo_cfg;
`uvm_component_utils(wdma_base_test)

function new(string name="wdma_base_test",uvm_component parent);
      super.new(name,parent);
endfunction : new

virtual function void set_default_sequence();
      uvm_config_db#(uvm_object_wrapper)::set(this,"vsqr.run_phase","default_sequence",wdma_1080p_ud_seq::type_id::get());
endfunction : set_default_sequence

virtual function void build_phase(uvm_phase phase);
      super.build_phase(phase);
      tb0=wdma_tb::type_id::create("tb0",this);
      vsqr=vsequencer::type_id::create("vsqr",this);
      vdo_cfg=vi_config::type_id::create("vdo_cfg");

      uvm_config_db#(vi_config)::set(this,"*","vdo_cfg",vdo_cfg);
      uvm_config_object::set(this,"tb0.vdo0*","cfg",vdo_cfg);

   set_default_sequence();

endfunction : build_phase

virtual function void connect_phase(uvm_phase phase);
      super.connect_phase(phase);
      vsqr.vdo_sqr=tb0.vdo0.master.sequencer;
endfunction : connect_phase

virtual task run_phase(uvm_phase phase);
      super.run_phase(phase);
      tb0.print();
endtask : run_phase
endclass : wdma_base_test

class wdma_1080p_30hz_test extends wdma_base_test;
`uvm_component_utils(wdma_1080p_30hz_test)

function new(string name, uvm_component parent);
      super.new(name,parent);
endfunction : new

function void set_default_sequence();
      uvm_config_db#(uvm_object_wrapper)::set(this,"vsqr.run_phase","default_sequence",wdma_1080p_30hz_seq::type_id::get());
endfunction : set_default_sequence

function void build_phase(uvm_phase phase);
      super.build_phase(phase);
      $display("30hz");
endfunction : build_phase

function void connect_phase(uvm_phase phase);
      super.connect_phase(phase);
endfunction : connect_phase

endclass : wdma_1080p_30hz_test

可是问题是，当我跑wdma_1080p_30hz_test时，启动的还是wdma_1080p_ud_seq，就好像wdma_1080p_30hz_test中改写的set_default_sequence()函数没有起作用一样。各位有什么办法解决呢？
