简单的全加器语言代码

Verilog投币式手机充电仪 清华大学数字电子技术基础课程EDA大作业。刚上电数码管全灭，按开始键后，数码管显示全为0。输入一定数额，数码管显示该数额的两倍对应的时间，按确认后开始倒计时。输入数额最多为20。若10秒没有按键，数码管全灭。(Verilog coin operated cell phone charger EDA major homework of digital electronic technology foundation course, Tsinghua University. Just put on the digital tube completely extinguished, press the start button, the digital tube display is 0. Enter a certain amount, the digital tube shows the amount of double the corresponding time, according to the confirmation began countdown. The maximum amount of input is 20. If there is no button in 10 seconds, the digital tube will die out.)

通过LED闪烁控制器的代码，使用Vivado工具配置定义一个IP核，在用户工程中可随意添加这个IP核作为设计的一部分，如同Vivado自带的IP核一样方便调用和集成。(Through the code of the LED scintillation controller, the Vivado tool is configured to define a IP core, and the IP kernel can be added as part of the design at random in user engineering. It is as convenient to call and integrate as the IP kernel with Vivado.)

说明：  图像去雾算法FPGA实现，使用xilinx Vivado开发环境(Image dehazing algorithm FPGA implementation using xilinx Vivado development environment)

说明：  该源码包是2.0版本的AMBA总线的Verilog语言模型，主要包括5个部分：AHB总线仲裁器，AHB-APB总线桥接器，AHB总线上从设备ROM模型，AHB总线上从设备RAM模型，参数定义。(This source code package is the model of V2.0 AMBA bus of ARM company, It mainly includes the following five parts: the AHB arbiter,AHB-APB bridge, AHB_Rom_Slave, AHB_Ram_Slave,Defines.)

verilog语言写的一个四层电梯程序，有优先级的判断。(verilog language of a four-story elevator procedures to determine priority.)

说明：  verilog编码器、计数器、加法器的程序(Verilog encoder, counter, adder procedures)

编码器信号的转换，用于控制打印机，UV平板打印机的喷头驱动输出信号，控制Y轴移动，需要将信号转换为运动控制器识别的信号才可以控制其运动。

超声波测距代码参考了网上的，数码管自己写的，我的是50mHz的晶振，测距不准可以自己修改一下。大佬勿喷。

10_100_1000 Mbps tri-mode ethernet MAC implements a MAC controller conforming to IEEE 802.3 specification. It is designed using less than 2000 LCs/LEs to implement full function. It will use inferred PADs to reduce technology dependancies. The whole project will be finished in TEN weeks inluding verilog coding,RTL level verification. A GUI configuration interface,created by tcl/tk script language,is convenient for configuring optional modules,FiFo depth and verifcation parameters. Furthermore,a verifcation system was designed with tcl/tk user interface,by which the stimulus can be generated automatically and the output packets can be verified with CRC-32 checksum.
