Finite-State Machine (FSM) Design

1 Finite-State Machine (FSM) Design FSMs, an important category of sequential circuits, are used frequently in designing digital systems. From the daily used electronic machines to the complex digital systems, FSMs are used everywhere. For example, in a station the vending Machine which dispatches ticket uses a simple FSM. In the complex digital systems the controlling part is most of the times implemented using FSMs. FSMs are generally of two types. 1. MEALY Machine : MEALY circuits are named after G. H, Mealy, one of the leading personalities in designing digital systems. The basic property of Mealy circuits is that the output is a function of the present input conditions and the present state (PS) of the circuit. 2. MOORE Machine : MOORE circuits are named after E. F. Moore, another leading personality in designing digital systems.

How To Design A Finite State Machine Here is an example of a designing a finite state machine, worked out from start to finish. Step 1: Describe the machine in words. In this example, we’ll be designing a controller for an elevator. The elevator can be at one of two floors: Ground or First. There is one button that controls the elevator, and ...

an example use-case for the Moore machine FSM template. The FSM shown in Figure 1 is useful because it exemplifies the following: 1. The concept of an initial state.1 2. States with non-conditional outward transitions. 3. States with conditional outward transitions. 1There must always be an initial state for the FSM to start at after a Reset. 1
