Learn how to implement Finite State Machines (FSM) in Verilog with practical Moore and Mealy machine examples. Understand FSM components, state encoding, and synchronous reset handling.
Learn how to design FSMs in Verilog, including Moore and Mealy models, state encoding methods, and implementation techniques for sequential circuit design.
In this project, we designed a flight controller (FC) module in SystemVerilog to fly a quadcopter. We deployed our code to an Altera Cyclone II FPGA development board and installed the board on the quadcopter, along with other necessary hardware.
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.
Registered outputs can be incorporated into the Verilogcode by using nonblocking assignments within a sequential always block. The FSM can be implemented with either a single sequential always block or by adding a second sequential always block to the design.
It is very important to run a Verilog simulation of your code with enough input combinations to stimulate all FSM transitions. There are plenty of FSMVerilogcode examples on this site, and elsewhere, that might help in getting you started.
This document will show you how to write a Moore FSM in a template-based fashion. This “cookie-cutter” approach is designed to avoid Verilog’s bug-prone areas, while keeping your code as non-verbose as possible. Verilog is a means to an end.
RAM-Based Finite State Machine (FSM) Synthesis: Large Finite State Machine (FSM) components can be made more compact and faster by implementing them in the block RAM resources provided in Virtex® devices and later technologies.
