Test stop [TEST_DONE] before the sequencer drop_objection

[enchanter]

I try to write my first UVM verification test environment, but I found the test is stopped before the sequencer drop_objection.

I highlight when the sequencer raise objection and when it drop it. But another highlight is [TEST_DONE] which happened before sequencer drop objection.

I have no idea why it happened and any could have a look to it.

Thanks.

hi,

switching on objection trace should tell you which object has been raising/dropping the objections (+UVM_OBJECTION_TRACE). eventually you have two parallel sequences running)
