频率计介绍了用VHDL语言编写的频率计的程序，详细编写了如何测频，如何计数频率。...

基于EDA技术中的对LED扫描电路的实验，程序能成功运行，能直接在开发板上看实验结果(EDA-based LED technology to scan the experimental circuit, the program can run successfully, can see directly in the development of on-board results)

this is verilog code for designing ALU in fpga.

书名：LDPC原理与应用。是国内第一本介绍用LDPC编、译码基本原理及应用技术的一本书。对用 vhdl 或verilog实现硬件编程LDPC的人开发无线通信是很好的资料(Title: LDPC Principles and Applications. Is the first book describes using LDPC Encoding and Decoding the basic principles and application of technology, a book. Right to use vhdl or verilog hardware programming LDPC people to achieve development of wireless communications is a very good information)

LDPC COded OFDM System

SPI verilog RTL code

a sequence generator

HDL verilog 电子密码锁 输入错误后有报警 输入正确后有提示(HDL Verilog electronic code lock input errors have prompted alarm input is correct)

很好的NAND Flash 硬件驱动语言，支持VHDL和verilog 语言方便移植，如果有想用FPGA直接驱动NAND flash而又不知如何下手的朋友肯定喜欢。(NAND Flash Controller Reference This reference design is used to interface a NAND Flash device and provides a simple host end interface. The host end interface of this design is user-configurable. It provides buffer select signal, buffer write enable signal, address bus, data bus, error status signal, control and handshake signals for the user......)

由VHDL 语言实现的D触发器利用的是QUARTUES环境已经得到验证-By the VHDL language using the D flip-flop is QUARTUES environment has been tested

数字示波器实验，利用AD、DA和VGA三个外设来实现简易示波器，DA外设发送正弦波给AD外设，AD外设解析成数字信号将数据送给VGA外设进行显示。在VGA上可以看到DA外设发送的波形、波形频率和波形峰峰值。(In the experiment of digital oscilloscope, AD, DA and VGA are used to realize simple oscilloscope. DA peripheral transmits sine wave to AD peripheral. AD peripheral resolves into digital signal and sends data to VGA peripheral for display. The waveform, waveform frequency and peak value of DA peripheral can be seen on VGA.)
