Sequential example (cont'd): abstract control
Finite-state diagram
- States: 5 states
- represent point in execution of machine
- each state has outputs
- Transitions: 6 from state to state, 5 self transitions, 1 global
- changes of state occur when clock says it’s ok
- based on value of inputs
- Inputs: reset, new, results of comparisons
- Output: open/closed
