这是一个HDB3的译码器，实现从HDB3双极性码到高低电平二值序列的转化-This is a decoder of the HDB3, HDB3 bipolar from high-low-level code to the conversion of binary sequences

说明：  verilog开发的经典教材，详细介绍了语法，常见历程，以及通用的程序段(verilog development of the classic materials, detailed information on syntax, common history, as well as the common program segment)

本人初学VHDL时编的比较系统的VHDL源程序 巨实用 -I am learning more systematic series of practical VHDL source Giant

FPGA控制AD逐点采集信号，并将AD转换后的数据串行发送出去。-FPGA to control the signal sampling point by point AD, AD conversion and serial data sent.

数字钟，数字电子技术课程设计常用内容，基于basys3平台(Digital clock, digital electronic technology curriculum design commonly used, based on the basys3 platform)

verilog源码，可实现两位的加法器，在xillinx foundation 3.1下验证通过-verilog source, the two can achieve Adder, In xillinx foundation 3.1 certification through

实现基于matlab的QMFB的完全重建，是一篇经过仿真且经过测试的正确的代码，可用价值比较高。(Based on matlab QMFB the completely rebuilt, is a through simulation and tested the correct code, can be relatively high value.)

本文介绍了一个使用 VHDL 描述计数器的设计、综合、仿真的全过程，作为我这一段 时间自学 FPGA/CPLD 的总结，如果有什么不正确的地方，敬请各位不幸看到这篇文章的 大侠们指正，在此表示感谢。当然，这是一个非常简单的时序逻辑电路实例，主要是详细 描述了一些软件的使用方法。文章中涉及的软件有Synplicity 公司出品的Synplify Pro 7.7.1； Altera 公司出品的 Quartus II 4.2；Mentor Graphics 公司出品的 ModelSim SE 6.0。 -This article describes a VHDL description of the use of counter design, synthesis, simulation of the entire process, this time as my self-FPGA/CPLD summary, if what has not the right place, please see this article that, unfortunately, the heroes They correct me, wish to express my gratitude. Of course, this is a very simple example of sequential logic circuit is mainly a detailed description of a number of software usage. Article involved in the software company has produced Synplicity

ADS7844 AD转换芯片的VHDL控制器-ADS7844 AD converter chip VHDL controller

FPGA开发超声波测距，可改写工业探伤或倒车测距等系统，quartus2下选择EP2C5Q208C8（CycloneⅡ） 支持目前淘宝上能买到的所有4-5针超声波模块 应用cycloneⅡ自带除法模块 开发板为有光技术YG2.1 生成电路规模较小 ！！注意：移植程序仅需重新约束数码管和超声波模块的针脚 (Ultrasonic Ranging FPGA development, industrial inspection or reverse rewritable ranging systems, EP2C5Q208C8 (CycloneⅡ) under quartus2 4-5 needle ultrasonic module supports all currently scouring the treasure can buy Applications cycloneⅡ own division module Development board bright technical YG2.1 Small scale generating circuit ! ! Note: The migration program only re-constraint digital and ultrasonic modules Pin)
