How to Terminate UVM simulation?

In reply to Chandra Bhushan Singh:

Hi chandra,

i put some display() statments at end of each phase , all messages are displayed.
i put only raise/drop objection in test. the raising is happening but not drop_objection();

Following message displaying :

The total objection count is 1

---------------------------------------------------------

Source Total

Count Count Object

---------------------------------------------------------

0 1 uvm_top

1 1 uvm_test_top

---------------------------------------------------------

my last statements in test :

phase.phase_done.display_objections();
phase.drop_objection(this);
phase.phase_done.display_objections();

Thanks
