Dynamically Changing the timeout while test is running

[Bhargav Katakam]

Hi,

Is it possible to change the timeout in the middle of the test incase if the test requires more time to run in UVM Testbench. There is a option to overwrite the timeout in UVM but it is not working as expected.

Specify which version of UVM.

I assume you are asking about the maximum time to run the simulation overall vs. extending objections.

Also, tell us what you tried, what you were expecting versus what happened.

You should be very carefully when using set_draintime, becaus it stops your simulation when set. You'll never know how long your simulation is running exactly.

set_draintime is useful when you are running a series of tests maybe overnight. If one of the jobs hangs and does not come to an end the other ones wll never be executed.

If there is a concern about parts of the simulation hanging, I suggest learning about how to use the uvm_heartbeat. I know engineers that swear by it and will not do a large design without it.
