【UVM】include_coverage not located message

有時在simulation时遇到不明來歷的log message，如下所示：

include coverage not located
   did you mean a_cfg?
   

debug發現在create ral model 時引入的

if(uvm_xxx_ral_model == null)begin
  uvm_xxx_ral_model = ral_uvm_xxx::type_id::create("uvm_xxx_ral_model",this);
  uvm_xxx_ral_model.configure(null,"top.dut_i");
  uvm_xxx_ral_model.build();
  uvm_xxx_ral_model.lock_model();

end

solution：

if(uvm_xxx_ral_model == null)begin
  uvm_reg::include_coverage("*",UVM_CVR_ALL);
  uvm_xxx_ral_model = ral_uvm_xxx::type_id::create("uvm_xxx_ral_model",this);
  uvm_xxx_ral_model.configure(null,"top.dut_i");
  uvm_xxx_ral_model.build();
  uvm_xxx_ral_model.set_coverage(UVM_CVR_ALL)
  uvm_xxx_ral_model.lock_model();

end
