[uvm_factory] how to remove the previous type override rule?


Recommended Posts

All,

My question as listed below, hope some body could give me some hint and thanks!

class b extends uvm_sequence;
class d extends b;
class c extends uvm_sequence;

  task body();
  b bb;
  `uvm_do(bb) // run b
  b::type_id::set_type_override(d::get_type());
  `uvm_do(bb) // run d
  // I hope to run b again in the next line, what should I do here?
  `uvm_do(bb)
  endtask
endclass

You can't undo a factory type override, but you can simply override it with the original type:

b::type_id::set_type_override(b::get_type());

Is this a trivial example that does not accurately reflect what you are trying to do, because here you simply need to use variables of different types:

task body();
 b bb;
 d dd;
 `uvm_do(bb) // run b
 `uvm_do(dd) // run d
 `uvm_do(bb)
endtask

Thanks for Janick,

1. Not really the same, for my case it is similar to select type of wheels or engines before `uvm_do(building_a_car)

2. overriding by same type does not works, it only shows the following message.

UVM_WARNING @ LINE: reporter [TYPDUP] Original and override type arguments are identical: b
