１３键键盘的ＶＨＤＬ顶层文件，我是初学着，希望对初学者有用...

在这个项目中我们使用 DE2 115 板上显示每次通过转移在左边按下某个键滚动你好。 这种架构使用管道和多路复用器

VHDL语言实现两个人掷骰子游戏，最多6次，大者胜则结束游戏并在点阵上显示，一直平手则一直进行直到达到6次。(Achieving the dice game between two people by using VHDL language.The maximum number of times is 6.The game will over when there is a biger one in one time,otherwise,the game will continue until the time of the game is up to 6.)

说明：  OFDM信号的发送与接收 ，需要自取。时域图，模糊图，削峰。(Sending and receiving of OFDM signal)

该工程是基于verilog hdl 语言编写的帧传输协议HDLC帧的发送端代码，会用QUATUSII的人都应该知道如何使用，希望能给你带来帮助-The project is based on the language verilog hdl frame transmission protocol HDLC frame of this generation- Codes will be used QUATUSII people should know how to use, in the hope of giving you helpful

FPGA实验，实现了蜂鸣器发出不同的音调，利用按键，很好玩的-FPGA experiment, realized the buzzer sounded a different tone, the use of keys, it is fun

LPDDR2 SDRAM memories compliant to JEDEC JESD209-2.

To increase simulation speed, ModelSim® can apply a variety of optimizations to your design. These include, but are not limited to, mergingprocesses, pulling constants out of loops, clock suppression, and signal collapsing. You control the level of optimization by specifying certain switches when you invoke the compiler.

对赛灵思7系列的三种型号的FPGA进行了综述(xilinx 7 productin overview)

使用verilog在fpga开发板实现流水灯，包括整个工程文件(This code is used for early learners to study verilog。)

使用uaf42设计的有源滤波器，高通滤波器的设计参数记录(Using uaf42 design active filters, high-pass filter design parameters recorded)
