8. Apply State Machines in Digital Circuit Design
State Machines, particularly Finite State Machines (FSMs), are essential digital logic models that illustrate system behavior driven by inputs and past events. The chapter outlines types of state machines, the components necessary for their implementation, and a defined design flow for creating FSMs. It highlights real-world applications and emphasizes the use of flip-flops and combinational logic for memory and transitions, respectively.

What we have learnt
- FSMs define predictable sequences of states in digital systems.
- Moore and Mealy models are two primary structures of FSMs.
- Memory components such as flip-flops and the use of logic gates or HDL are crucial for FSM functionality.
- The design process for FSMs enhances modularity and clarity in digital circuit design.
Key Concepts
- -- Finite State Machine (FSM)
- A digital logic model used to represent the behavior of systems that change based on inputs and past events, consisting of states, transitions, and outputs.
- -- Moore Machine
- A type of state machine where the outputs depend solely on the current state.
- -- Mealy Machine
- A type of state machine where the outputs depend on both the current state and the current input.
- -- State Diagram
- A graphical representation that illustrates states of an FSM and transitions between them.
- -- NextState Logic
- The logic that determines how to transition from the current state to the next state based on inputs.
- -- Output Logic
- The logic that drives the outputs of the FSM based on the current state.
