Xilinx的FPGA开发DEMO例程，功能相对来说比较全面，适合新手参考。...

说明：  该资料是用vhdl编写的按键消抖程序，按键消抖在使用按键的数字电路中非常重要，如果不对按键信号进行处理，有可能会出现大量错误的按键信号。文件key_xd.vhd是按键消抖程序，文件key_xd.vwf是仿真波形文件。该程序已经通过仿真测试，并且在电路板上调试通过，效果理想。(The information is written in the key consumer vhdl shaking procedures, key consumer shaking in digital circuits using the buttons is very important, if not key signal processing, there may be a lot of the wrong button signal. File key_xd.vhd is key consumer shake procedure is the simulation waveform file key_xd.vwf file. The program has been tested by simulation and debugging in circuit board by, the results are satisfactory.)

quick reference guide to verilog HDL

基于Basys3的数字钟实例，主要用于Basys3、vivado开发环境入门。源码使用VerilogHDL(Based on digital clock instance Basys3, mainly for Basys3, vivado development environment started. Use Code VerilogHDL)

说明：  基于altera fpga的fir IP核实现希尔伯特变换，有matlab仿真(Based on Altera FPGA fir IP core to achieve Hilbert transform, matlab simulation)

用verilog语言编写的4位算术逻辑单元ALU,功能参考74181，包含.v文件以及测试用.vwf文件-Verilog languages with four arithmetic logic unit ALU, functional reference to 74,181, including. V documents and testing. Vwf document

说明：  基於空間向量調變的開關法，在於載波做比較切出方波再送至開關讓馬達啟動(Based on the switching method of space vector modulation, the square wave is cut out for carrier comparison and sent to the switch to start the moto)

改VHDL代码可以实现超声波测距的功能，其精确度达到US级，可以用七段数码管显示其数值(sound ranging sound ranging sound ranging sound ranging sound ranging sound ranging sound ranging sound ranging sound ranging sound ranging sound ranging )

介绍了基于VHDL的可编程分频器在波形发生器中的应用的方法，利用这一方法， 可使波形频率在大范围内变化。()

有用的数字钟设计文档，有秒表、闹钟等模块，希望对大家有用！(JUST LEARN FROM IT!!ENJOY!)

通过MATLAB产生单脉冲信号的数据，存储下来作为verilog代码实现的DDS的数据源，用于验证DA数据的ddio的调试是否有问题。(The data of monopulse signal generated by MATLAB is stored as the data source of DDS implemented by Verilog code to verify whether the ddio debugging of DA data is problematic.)
