利用FPGA，产生三相SPWM波，与后继硬件电路配合，形成三相电源。高效，实用。(Using FPGA, produce three-phase SPWM wave, with subsequent hardware circuit with the formation of three-phase power. Efficient and practical.)

verilog代码实现的数字密码锁。通过4个并行的10位移位寄存器，分别记录在时钟上升沿时A,B,C,D的输入情况，比如某上升沿输入A，相应时刻A对应的移位寄存器输入1，其他三个移位寄存器输入都为0.另外4个并行的10位寄存器记录密码。这样，密码锁不仅可以识别字符数量，还可以判断出字符的输入次序。(verilog code of digital lock. By four parallel 10-bit shift register, respectively, recorded in the clock rising edge A, B, C, D of inputs, such as a rising edge of input A, the corresponding moments A 1 corresponding to the input shift register, the other three shift bit register inputs are 0. another four parallel 10-bit registers record the password. This lock can not only identify the number of characters, you can also determine the character of the input sequence.)

very good code for edge detection based on vhdl programming.

XILINX中LWIP协议例子应用指南，有实际例子(Examples of applications in LWIP agreement XILINX Guide, a practical example)

目前最新的OVL库，里面是标准的ASSERTION模块，支持VHDL刚Verilog，最近在做AXI协议验证的时候用到，分享下(The latest OVL(open verification library),including all standard module of assertions(VHDL and Verilog). It can be used into AXI Protocl Verification. Just share with you guys.)

数字频率计毕业论文 不是自己做的-Digital Cymometer thesis do not own. . Ha ha

应用背景交通信号灯，自动检测有无行人，根据检测的状态来调节灯的状态，完整VHDL代码外加模拟仿真时序图关键技术 设计一个交通信号灯，有A、B两条路，装置自动检测A路口和B路口是否有人，RST信号能够将交通灯的状态置到A路绿灯亮，B路红灯亮，5秒钟检测一个状态，当A路口有人时，A路绿灯保持，每隔5秒检测一次，当A路口没有人了，绿灯变为黄灯，5S后再变为红灯，同时B路口变为绿灯，再5S后检测B是否有人，有人保持绿灯，没人变为黄灯，再变为红灯，依次进行~~
