使用VHDL语言编程，烧录在芯片运行的倒数5秒响4声短铃最后一声长音的数字钟...

说明：  FIFO: First in, First out 代表先进的数据先出，后进的数据后出。Xilinx 在 VIVADO 里为我们已经提供了 FIFO 的 IP 核, 我们只需通过 IP 核例化一个 FIFO，根据 FIFO 的读写时序来写入和读取FIFO 中存储的数据。(FIFO: first in, first out represents the first out of advanced data, and the last in data is the last out. Xilinx has provided us with the IP core of FIFO in vivado. We only need to instantiate a FIFO through the IP core, and write and read the data stored in FIFO according to the FIFO read-write timing.)

此实验例程适用于Actel Flash架构的ProASIC3/E系列FPGA，适合于FPGA及Verilog HDL的初学者，配套EasyFPGA030开发套件。-Routine application of this experiment in the Actel Flash architecture ProASIC3/E series FPGA, fit in the FPGA and Verilog HDL for beginners and supporting development kit EasyFPGA030.

Verilog的应用例程，包含了基本的硬件编程，加法器，触发器(Application of Verilog routines, including the basic hardware programming, adders, flip-flop)

这个我也太清楚是什么 反正师兄们说有用 发大家-I am also very clear that what is useful anyway, say senior U.S. fa

电子时钟，可以显示四位，两位显示分钟，两位显示秒，可以用按键控制清零，以及加减数(Electronic clock, you can display four bit, two bit display minutes, the second display seconds, can be used to control the key to clear, and the addition of subtraction)

VERILOG HDL pid算法 带仿真验证(pid by verilog HDL)

Used for Time shifting discrete signals, it can do both integral and fractional sampling period delay. Original.

基于FPGA的频率测量，能测量方波信号的频率、占空比、相位差。范围100mHz~200MHz，精度0.0001Hz(The frequency measurement based on FPGA can measure the frequency, duty cycle and phase difference of the square wave signal. Range 100mHz~200MHz, precision 0.0001Hz)

fpga Verilog 控制读写flash (fpga Verilog flash )

TCM解码，VHDL代码，是我在工作中做的工程代码，时序稳定，里面有syn以及软判决的算法，经典-TCM decoder, VHDL code, yes, I do work in the project code, timing stability, There are syn and soft-decision algorithm, classic!
