Hi, all,
I met one problem when i configure sub-sequencers of virtual sequencer using uvm_config_db. Here are the codes and VCS reports:
-------codes-------
class my_subenv extends uvm_env;
...
function void build_phase(uvm_phase phase);
...
v_sqr = vsequencer::type_id::create($sformatf("v_sqr%0d", subenv_ID), this);
// configuration, set default_sequence as the virtual sequencer
uvm_config_db#(uvm_object_wrapper)::set(this, "v_sqr.run_phase", "default_sequence", vsequence::type_id::get());
...
endfunction : build_phase
function void connect_phase(uvm_phase phase);
...
uvm_config_db#(uvm_sequencer)::set(this, "v_sqr", "cfg_sqr", this.cfg_agt.cfg_sqr);
uvm_config_db#(uvm_sequencer)::set(this, "v_sqr", "str_sqr", this.str_agt.str_sqr);
...
endfunction : connect_phase
...
endclass : my_subenv
-------VCS reports--------

By the way, my_config_sequencer and my_str_sequencer are classes derived from uvm_sequencer, so I think the complex type should be compatible. And the codes are wriiten according chapter 4.8 of the uvm_users_guide_1.1.pdf document. Should there be some phrases like uvm_config_db#(uvm_sequencer)::get() in my_subenv or other places?
Thanks
