基于CPLD的交通信号灯的实现

先设计序列发生器产生序列：1011010001101010；再设计序列检测器，检测序列发生器产生序列，若检测到信号与预置待测信号相同，则输出“1”，否则输出“0”，并且将检测到的信号的显示出来。(First design sequence generator sequence: 1011010001101010 redesign sequence detector to detect sequence generator sequence, if the same signal is detected with the preset test signal output " 1" , otherwise " 0" , and the detection display signal out.)

减1计数器 一、设计要求 用Verilog HDL语言设计一个计数器。 要求计数器具有异步置位/复位功能，可以进行自增和自减计数，其计数周期为2^N（N为二进制位数）。 二、设计原理 输入/输出说明： d：异步置数数据输入； q：当前计数器数据输出； clock：时钟脉冲； count_en：计数器计数使能控制（1：计数/0：停止计数）； updown：计数器进行自加/自减运算控制（1：自加/0：自减）； load_d-a counter a reduction, design requirements using Verilog HDL design of a counter. Asynchronous requests with counter-home/reset functions can be carried out by self and self-count reduction, cycle counting of 2 ^ N (N for binary digit). Second, the principle of design input/output Description : d : asynchronous home several data input; Q : The current counter data output; Clock : clock pulse; Count_en : Counting enable control (1 : Counting/0 : Stop counting); Updown : dollars several self-Canada/reduction Operational control (1 : Since the plus/0 : Since decrease); load_d
