篮球24秒可控计时器设计

用于实现锁相光子计数技术的累加器，verilog语言(Accumulator achieve specific cases for accumulator lock detection of photon counting technique)

verilog数字系统设计，一本很好的verilog学习的书籍，很适合初学者(verilog digital system design, a good verilog learning books, it is suitable for beginners)

设计制作一个检测4*4矩阵键盘的按键编码的实验，把实际按键的键值的八位编码先转换成从0000—1111的编码，再译成数码管能识别的八位编码，在数码管动态显示时，4*4矩阵键盘的第一行对应00—03，第二行对应04—07，第三行08—11，第四行对应12—15。(Design a 4* 4 matrix keyboard key coding experiments to detect the key the actual key octet coded first convert from 0000-1111 encoding, and then translated into digital tube to identify the eight coding, digital tube dynamic display, the first line of the 4* 4 matrix keyboard corresponding to 00-03, the second line corresponds to 04-07, the third line of 08-11, the fourth line corresponds to 12-15.)

说明：  用Verilog编写的简单的运算单元（ALU），可实现加、减、与、或、异或、非、左、右移等功能(Verilog prepared with simple arithmetic unit (ALU), can be add, subtract, and, or, exclusive-OR, non-, left, and other functions shifted to right)

排队电路设计，适用于EDA大作业，大学生适合使用，初学者，仅仅是vhdl的语言，可以借鉴(Queuing circuit design, suitable for EDA operation, college students suitable for use, beginners, only the language of VHDL, can learn from)

同步与异步FIFO的verilog实现，包括源代码，testbench，测试以及综合通过，还有相关参考资料(Synchronous and asynchronous FIFO verilog achieve, including source code, testbench, test and integrated through, as well as related references)

基于verilog的RS编码器 绝对实用(Based on the RS encoder verilog absolute utility)
