Synchronizers are introduced to improve the reliability of complex state machines. To
complete our the discussion, we present two additional state machine design methods: the twoassignment
PS/NS method and the hybrid PS/SN method. You can implement and download the
last complex state machine design example, to observe it working in hardware, if you so desire.
