说明：  设计一简易数字频率计，其基本要求是： 1)测量频率范围0～999999Hz； 2)最大读数999999HZ,闸门信号的采样时间为1s；. 3)被测信号可以是正弦波、三角波和方波； 4)显示方式为6位十进制数显示； 5）具有超过量程报警功能。 5)输入信号最大幅值可扩展。 6）测量误差小于+-0.1%。 7)完成全部设计后，可使用EWB进行仿真，检测试验设计电路的正确性。(The basic requirements of designing a simple digital frequency meter are: 1) The measuring frequency range is 0-999999 Hz. 2) The maximum reading is 999999HZ, and the sampling time of gate signal is 1 s. 3) The measured signal can be sine wave, triangle wave and square wave. 4) The display mode is 6-bit decimal number display. 5) It has alarm function beyond range. 5) The maximum amplitude of input signal can be expanded. 6) The measurement error is less than +0.1%. 7) After completing all the design, EWB can be used to simulate and test the correctness of the circuit.)

利用matlab，对偏振控制器进行仿真，最终在邦加球上进行显示(Using matlab, simulation of the polarization controller eventually be displayed on the Poincare Sphere)

梁祝音乐verilog code --适用于QUATUS II 开发环境下，适合于verilog入门学员(the verilog code of liangzhu )

本代码用verilog语言配合sopc和nios实现了串口调试的目的。软件编程用C语言描述，只是比较简单的例子，适合初学者做了解用，本人亲自在EP2C8Q上实践。(The code to use verilog language sopc and nios achieved with serial debugging purposes. Software programming using C language description, but relatively simple example for beginners to do with understanding, I personally EP2C8Q on practice.)

键盘按键消抖,短时间内的摁键键值采集，在规定时间内，如果存在按键的上升沿和下降沿，不予以采集，超过该时间，则采集为该键当前状态值

说明：  uvm lab代码以及uvm1.2源码，带有使用说明文档，可以照着文档一步一步深入了解uvm代码。(The code of UVM lab and the source code of uvm1.2 are provided with instruction documents. You can follow the documents step by step to understand the UVM code.)

This is a divider, which is depicted as well. It is a programming language Vhdl.

代码文件夹： ARVI_FSM.v为顶层文件，用于模拟时用。 dataHex.dat 为模拟输入文件（只有10行，象征的意思。实际我们模拟时，dataHex.dat文件足有1个多GB） dataFormat.dat为输入文件对应的带格式的文件 使用modelsim模拟时，将dataHex.dat名字改为CPUContext.txt 结果: result.txt (Code folder: ARVI_FSM.v for top-level documents used for the simulation. dataHex.dat for analog input files (only 10 line, the meaning of the symbol. actual simulation we, dataHex.dat documents have more than one full GB) dataFormat.dat for the input file the corresponding file with modelsim simulation used to dataHex.dat name to CPUContext.txt results: result.txt)
