How can you write an FSM code in Verilog?

How can you write an FSM code in Verilog?

Basically a FSM consists of combinational, sequential and output logic. Combinational logic is used to decide the next state of the FSM, sequential logic is used to store the current state of the FSM. The output logic is a mixture of both combo and seq logic as shown in the figure below.

What is FSM design?

The definition of a finite state machine is, the term finite state machine (FSM) is also known as finite state automation. FSM is a calculation model that can be executed with the help of hardware otherwise software. This is used for creating sequential logic as well as a few computer programs.

What is FSM discuss types of FSM?

An FSM is defined by a list of its states, its initial state, and the inputs that trigger each transition. Finite-state machines are of two types—deterministic finite-state machines and non-deterministic finite-state machines.

What happens if the input is low in FSM?

What happens if the input is low in FSM? Explanation: There is no transition in the state if the input is low. If the system is in a particular state, it remains in that state only until the input becomes high.

Why is FSM needed?

A Finite State Machine, or FSM, is a computation model that can be used to simulate sequential logic, or, in other words, to represent and control execution flow. Finite State Machines can be used to model problems in many fields, including mathematics, artificial intelligence, games or linguistics.

How do you write a state machine code?

How to Design State Machine to Write a Bug-free Code

1. Identify initial state. Before you write a code, identify the first state of your application when it becomes a finished product.
2. Identify events. Events are what cause an application to move from a state to another – transition.
3. Determine transition.

Why do we use FSM?

What are the different types of FSM?

Finite-state machines are of two types—deterministic finite-state machines and non-deterministic finite-state machines. A deterministic finite-state machine can be constructed equivalent to any non-deterministic one.
