多功能数字钟，在quartusII软件平台上实现的verilog源代码。大家试试看。(Multifunctional digital clock in quartusII software platform to achieve the verilog source code. We try.)

FPGA实现反正切功能，工程原件，包括测试文件，能够很好实现该功能(FPGA implements arctangent function, original engineering)

用FPGA实现OFDM系统，硬件语言为Verilog，环境为xilinx，详细介绍了接收机和发射机各个模块的源代码(OFDM system with a FPGA implementation, hardware language Verilog, environment xilinx, details of receiver and transmitter modules source code)

说明：  能实现输入0.5 1 5块钱的累加，然后对应购买的商品价格进行比较，显示找的钱数或错误灯(MY English is very good)

说明：  实现24小时计时，因为位数不够，这里是12进位，可自行调整进位数(Realize 24-hour timing, because the number of digits is not enough, here is 12 carry, you can adjust the carry number by yourself.)
