Correct way to kill sequences

@chr_sue,

The sequence stopping is being done for active reset testing where we yank the reset randomly somewhere in the main_phase to see if the DUT can handle a reset while traffic is running. This is routinely done for blocks that need this kind of verification.

If you are familiar with phase jumping and active reset testing, I beleive one has to stop_sequences at some point to achieve this. If you think that is not the case, can you shed light on how you have done it with some example code.

For example, this is one paper that talks about active reset testing and phase jumping. This one also uses the stop_sequences to do active reset testing.
