In reply to DVJoe:
The scenario you are describing can be implemented using run_phase only. You do not need any phase jumping.
You can run your main traffic and start a reset sequence by grabbing the main traffic sequence. Executing the reset and afterwards continuewith the main traffic. This is a very easy implementation.
For a code example see the code examples in the Verification Academy.
Wrt to the paper you are mentioning. This is another way of doing this. I my eyes it is not really easier than what I was proposing.
