This chapter covers finite state machine (FSM), which is a sequential circuit with “random” transition patterns. The representation, timing and implementation issues of FSMs are studied with an emphasis on its use as the control circuit for a large, complex system. | Finite State Machine RTL Hardware Design by P.
