How to pass the value to the variable of uvm_sequence object

Hi all,

How to pass the value to the variable of uvm_sequence object?

1. use uvm_config_db

2. assign directly

When i use the first way, i found that maybe uvm_config_db::get() can only use in the uvm_component  class. Then i use the second way, I cann't pass the value to the variable successfully.

Does anybody know the reason? Thanks in advance.

pieces of code of the first way:

In top:

uvm_config_db#(uvm_bitstream_t)::set(uvm_root::get(), "*", "my_cpu_id", HOST_NUM);

In my_sub_sequence which extends from uvm_sequence:

void'(uvm_config_db#(uvm_bitstream_t)::get(this, "", "my_cpu_id", my_cpu_id));

Result: VCS reports error.

pieces of code of the second way:

In v_sequence:

    for (int i = 0; i < host_num; i++) begin
      inst_name = $sformatf("sub_seq[%0d]", i);
      //sub_seq[i] = my_sub_sequence::type_id::create(inst_name,,get_full_name());
      sub_seq[i] = new(inst_name);
      sub_seq[i].my_cpu_id = i;
    end

In my_sub_sequence:

int my_cpu_id;
...
virtual task body();
...
$display("my_cpu_id = %0d", my_cpu_id);
...
endtask

Result: every my_cpu_id's value display 0, not 0, 1, 2, 3.
