Verilog HDL语言编写的5分频电路。采用两路时钟相逻辑作用产生。-Verilog HDL prepared by the five-frequency circuits. Clock using two phase logic role.

利用Cadence Allegro PCB SI进行SI仿真分析(Performed using the Cadence Allegro PCB SI SI simulation analysis)

说明：   基于VHDL语言数字秒表设计,在FPGA实验平台下开发(Digital stopwatch design based on VHDL, FPGA experimental platform under development)

说明：  内有一PCI 主 和PCI从，PCI TARGET 都是公开代码的，是工程文件，有仿真工程，使用说明。觉得好的就推荐一下。 本PCI_HOST目前支持： 1、 对目标PCI_T进行配置； 2、 对目标进行单周期读写； 3、 可以工作在33MHZ和66MHZ 4、 支持目标跟不上时插入最长10时钟的等待。 ALTERA的PCI竟然收费的！！！软件里面调试仿真了半天，终于调通了，到了下载就突然弹出窗口说包含了有限制的IP CORE，是限制使用的(There is a PCI from PCI proprietors, PCI TARGET is open source, is the project document, there is simulation project, for use. Feel good about the recommendation. The PCI_HOST currently supports: 1, on the target configuration PCI_T 2, on the target for single-cycle read and write 3, can work in the 33Mhz and 66MHZ 4, to support the goals behind to insert a maximum of 10 clock hours of waiting. ALTERA the PCI even charges! ! ! Inside simulation software debugging for a long time, and finally had transferred to the download on the sudden pop-up window that contains a limited IP CORE, is to restrict the use of)

基于可编程逻辑器件FPGA的独立式键盘设计，内部具有硬件去抖动电路。值得一看-FPGA-based programmable logic device stand-alone keyboard design, the internal hardware to jitter circuit. Worth a visit

一位加法全加器，可以实现低位进位输入和高位进位输出。(full adder)

数字频率计~ VHDL 实现 可以实现频率的测量和现实的功能 8位-digtal frequency tester (use vhdl) can be used to test frequency (8bit)

基于VHDL的LCD显示程序,包含完整的源代码,锁脚文件以及下载文件,可直接下载使用-VHDL based on the LCD display program, including complete source code, locking pin, as well as download files documents can be directly downloaded using

VGA controller : Genarate a VGA signal from your inout information as color info of each pixel

介绍专用集成电路设计的一本书，很有参考价值，适合高年级本科生和研究生(Introduction ASIC design a book, a good reference for senior undergraduate and postgraduate)
