Description

This (obviously) causes an infinite loop, so will need something analogous to the loop warping support to let us stop again.

Research direction

No file, test, or entry point is named. Start by locating the existing loop-warping support in the OTBN DV code and the branch-to-self coverpoint; done means the coverpoint is covered without leaving the simulation in an infinite loop.
