cliffc Posted March 25, 2012 Report Share Posted March 25, 2012 Hi, All - I have a small example (test1, env, agent, driver, sequencer, sequence and sequence_item) coded with trans extended from uvm_sequence_item. All items are registered with the factory. The driver and sequencer are parameterized to trans, as is the sequence. The trans has a convert2string virtual function so I can display all of the transactions executed by the sequence. I coded a trans2 transaction extended from trans, with convert2string updates to show "trans2", and a separate test with a build_phase() that does: set_type_override_by_type(trans::get_type(), trans2::get_type()); But when I run the second test, I still see the trans1 messages. I also printed out the factory information in the test's end_of_elaboration_phase() and it shows that trans2 should replace trans. I then created a second driver, extended from the original driver, added an additional `uvm_info message to the run_phase() and a third test that does: set_type_override_by_type(tb_driver::get_type(), tb_driver2::get_type()); And when I run, the second driver messages appear, but I still do not see the trans2 messages. Again, printing the factory.print() shows that both the tb_driver and trans types should be replaced by tb_driver2 and trans2. Any hints as to why the transaction and transaction printing of the trans2 transaction do not seem to be working?
