USB2.0的VHDL描述，很经典了，欢迎大家下载-USB2.0 the VHDL description, very classic, and welcomes everyone to download

原创，帧同步器的Verilog代码，在FPGA上验证实现过，无误。作为通信系统帧传输的仿真，有限状态机同步态和失步态的切换仿真。(Original Verilog code for frame synchronization, verify the implementation on the FPGA, and correct. Frame transmission as the communication system simulation, finite state machine synchronous state and the loss of the switching simulation of gait.)

基于AT89C51的密码锁（掉电可记忆密码）的程序(Based on AT89C51 lock (down to remembering passwords) program)

关于USB开发的verilog开发程序，非常的全面，学习FPGA开发时用得着。(About USB development verilog development process, very comprehensive, learning FPGA development time worthwhile.)

Designing a synchronous finite state machine (FSM) is a common task for a digital logic engineer. This paper discusses a variety of issues regarding FSM design using Synopsys Design Compiler. Verilog and VHDL coding styles are presented, and different methodologies are compared using real-world examples.

基于FPGA实现蜂鸣器播放音乐的功能 使用芯片为EP2C8Q208C8N,使用普通蜂鸣器，由于频率不同可实现放歌功能，本例设计的是《友谊地久天长》，使用Verilog语言编程，本例子有工程文件、仿真、波形，经过测试可以使用。(Play music based on FPGA buzzer functions using chip EP2C8Q208C8N, using ordinary buzzer, since the frequency of different functions can be realized sing, in this case the design is " Auld Lang Syne" , using Verilog language programming, this project examples files, simulation, waveform, tested can be used.)
