problem about multiple sequencers which have the same name

[mrforever]

Hi, experts,

I met such a problem. Here are the codes and the vcs reports:

-------codes--------

class my_env extends uvm_env;

   my_sub_env subenv[];

   ...

   // build phase

   function void build_phase(uvm_phase phase);

      ...

      subenv=new[10];

      for (int i =0; i <10; i++) begin

         subenv = my_sub_env::type_id::create(sformatf("subenv%0d", i), this);

      end

      ...

   endfunction: build_phase

 

   // connect phase

   function void connect_phase(uvm_phase phase);

      ...

 

      foreach(subenv) begin

        reg_R.a_map.set_sequencer(subenv.v_sqr.cfg_sqr, reg2apb);

      end 

      ...

   endfunction: connect_phase

endclass: my_env

 

class my_sub_env extends uvm_env;

   vsequencer v_sqr;

   ...

   function void build_phase(uvm_phase phase);

      ...

      v_sqr = vsequencer::type_id::create("v_sqr", this);

      ...

   endfunction: build_phase

   ...

endclass: my_sub_env

 

-------reports--------

The vcs reports such an error:

UVM_FATAL /EDA_Tools/synopsys/vcs1209/etc/uvm-1.1/uvm-1.1c/src/base/uvm_component.svh(1744) @ 0: v_sqr [CLDEXT] Name 'v_sqr' is not unique to other top-level instances. If parent is a module, build a unique name by combining the the module name and component name: $sformatf("%m.%s","v_sqr").

 

How can I build a unique name when the parent isn't a module. I mean I cann't build a unique name because there is only one v_sqr in class my_sub_env. I have built a unique name for each subenv, that is sformatf("subenv%0d", i). Does the reports mean that each object should have a unique name when there are multiple subenvs?

Could anybody help me to solve this problem?

Thanks in advance.

You can have one int variable ID to mark the component as the unique one. Then use uvm_config_db to pass specific value to it.
