Hello, I was wondering if anyone had any ideas on why my test is hanging at the end of the run phase and how to resolve it correctly. The last of the output is listed below. The testbench has a series of agents, each including a monitor, producer driver, consumer driver, and scoreboard. At the end of the run phase when the test is hanging I'm able to step through code and see it's executing in a forever loop in the monitor and consumer driver. In both of these I'm never raising any objection. Tracing through the UVM code it seems it's waiting for all threads to exit before moving on. Some questions: Why should it wait for threads to exit if they never raised any objection? Do I need to kill these threads? What is the best practice? thanks!
