基于延迟线的数字脉冲宽度调制，用于电力电子设备的触发信号产生(puls wide modulator based on delayline)

verilog源代码，实现两种方法的模3运算。(verilog source code，to implement the calculation of mod-3 by two means.)

基于QuartusII环境下以模块化的形式做成的视频复合同步信号。-QuartusII-based environment to create the form of modular composite video sync signal.

说明：  串口通信vivado实现，带有仿真文件，可实现数据收发(the uart program based on vivado)

成功解决FPGA设计时序问题的三大点.word说明文档，很详细(FPGA design timing problems successfully solved the three points)

此文件给出了一个多功能交通灯的VHDL代码实现，可作为电赛的准备材料-This paper gives a multi-functional traffic lights to achieve the VHDL code can be used as electric materials Cup preparations

In the data management system a significant role of the Data link layer is to convert the unreliable physical link between reader and tag into a reliable link. Therefore, the RFID system employs the Cyclic Redundancy Check (CRC) as an error detection scheme. In addition for reader to communicate with the multiple tags, an anti-collision technique is required. The technique is to coordinate the communication between the reader and the tags. The common deterministic anti-collision techniques are based on the Tree algorithm such as the Binary Tree and the Query Tree algorithms.

说明：  FPGA数码管显示秒表实验 三种方法实现： 方法一： 对秒计数，得到（秒显示）0~9， 对（秒显示）计数，得到（分秒显示）0~5， 对（分秒显示）计数，得到（分钟显示）0~5， 注意进位时机 方法二： 对秒计数，得到（秒显示）0~9 对秒计数，得到（分秒显示）0~5 对秒计数，得到（分钟显示）0~5 方法三： 只对秒计数，分别取模 %60得到分钟显示 ************************ 余数%10得到分秒显示 （据说）取模运算占资源！！！！（也能接受？好像...） 再剩下的余数为秒显示 ************************(Experiment of Digital Tube Display Stopwatch Based on FPGA Three ways to achieve)

HLD开发语言ADHL介绍。ADHL是ALTERA公司开发的硬件描述语言，也是一种较为流行的开发工具。是介绍AHDL的入门培训资料。-HLD development language ADHL introduction. ADHL is ALTERA developed hardware description language, but also a more popular development tools. AHDL is the introduction of induction training information.
