How to make sure the task is finished

UVM
1

I have a question about the task.

task task1();
while(size < 10000) begin
register_write(XXXX); <== this register_write() is also a task
end
endtask

task task2();
… // some other things to do
endtask

and in my test, I’d like to trigger task1 firstly and then task2. but I want to make sure all stuff in task1 is finished before task2 begins. How to handle this ? Thank you!

Tasks are blocking. If you call the tasks sequentially, the second task won’t start until the first task is complete. This changes if you use fork statements.

I am sorry the scenario I described is not correct. Please ignore my question above.

Here is what I asked for help.

task my_task1();
while(size < 10000) begin
my_sub_task();
end
endtask;

task my_sub_task();
my_trans tr;
tr.set_parent_sequence(my_seq);
tr.set_sequencer(my_sqr);
my_seq.start_item(tr);
my_seq.finish_item(tr);
tr.end_event.wait_on();
endtask

task my_task2();
…
endtask

I want to know how to make sure all transaction is finished in the task1 (or say in my_sub_task) before my_task2 is started.

Thank you !

My answer is the same. Is there something confusing in what I said?
