From: Wen Yang <redacted>
Add the Graphviz DOT specification of the tlob hybrid automaton to
tools/verification/models/. The model has three states (running,
waiting, sleeping), four transitions (switch_in, preempt, wakeup,
sleep), and a single clock invariant clk_elapsed < BUDGET_NS() active
in all states.
