基于Basys3的数字钟实例，主要用于Basys3、vivado开发环境入门。源码使用VerilogHDL(Based on digital clock instance Basys3, mainly for Basys3, vivado development environment started. Use Code VerilogHDL)

摘要：本文主要介绍以CPLD 芯片进行十字路口的交通灯的设计，用CPLD 作为交通灯控制器的主控芯片，采用VHDL 语言编写控制程序，利用CPLD的可重复编程和在动态系统重构的特性，大大地提高了数字系统设计的灵活性和通用性。 关键词：CPLD；VHDL；交通灯控制器 中图分类号：TP39 Abstract ：This paper introduces the electronic-traffic lamp, which is based on the VHDL and is completed by-Abstract: This paper introduces the CPLD chip to the traffic lights at the crossroads of design, traffic lights with CPLD as the master controller chip, the use of VHDL language control procedures, the use of CPLD re-programming and dynamic system reconfiguration in the features greatly enhance the digital system design flexibility and versatility. Keywords: CPLD VHDL traffic lights controller CLC number: TP39 Abstract: This paper introduces the electronic-traffic lamp, which is based on the VHDL and is completed by

实现了一个四层单电梯控制系统。门可以自动开关，也可以手动开关。代码可以集成，不超过驱动的现象。

四位全家器的VHDL语言模块，已经在ISE8.1上经过测试通过-family of four VHDL modules, has been tested on ISE8.1 through

---实现的部分VHDL 程序如下。 　　--- elsif clk1x event and clk1x = 1 then ---if std_logic_vector(length_no) >= “0001” and std_logic_vector(length_no) <= “1001” then -----数据帧数据由接收串行数据端移位入接收移位寄存器---rsr(0) <= rxda --- rsr(7 downto 1) <= rsr(6 downto 0) --- parity <= parity xor rsr(7) --- elsif std_logic_vector(length_no) = “1010” then --- rbr <= rsr --接收移位寄存器数据进入接收缓冲器--- ...... --- end if(--- achieve some VHDL procedure is as follows.--- Elsif clk1x event and then a clk1x = s--- if td_logic_vector (length_no))
