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