Fsm Based Digital Design Using Verilog Hdl Pdf Guide

A Finite State Machine is a mathematical model that can be in one of a finite number of states. It can change state based on input signals and produce output signals. FSMs are commonly used in digital design to implement sequential logic systems, such as counters, timers, and control units.

Let’s consider a simple counter FSM that counts from 0 to 7. The FSM has one input, clk , which is a clock signal, and one output, count , which is the current count. A Finite State Machine is a mathematical model
