3.1 Introduction

 

This chapter provides techniques for designing sequential logic using Verilog HDL. Sequential logic circuits consist of combinational logic and storage elements, such as SR latches, D flip-flops, and JK flip-flops. They are specified as sequential because the operations of the circuit are executed in sequence. Since these circuits (or sequential machines) contain a finite number of internal states, they are also referred to as finite state machines. A state is a set of values that is specified at different locations in the state machine. ...
