基于有限状态机和HDL的交通灯控制器设计

The Design of Traffic Light Controller Based on Finite State Machine and HDL

本文用有限状态机（Finite State Machine，FSM）和硬件描述语言（Hardware Description Language，HDL）来进行交通灯控制器的设计与FPGA实现。文中讨论和比较了交通灯控制器的几种不同设计，得到了有益的启示。

This paper discusses in detail the design of a traffic light controller based on Finite State Machine （FSM） and Verilog HDL. Several different designs are presented and compared in the paper, drawing useful conclusions and giving helpful hints.
