135个经典VerilogHDL源码和说明文档，入门的好资料

costas载波恢复算法 锁相环路，注释很清楚(costas carrier recovery algorithm PLL)

在EDA实验课上面，自己编写的NCO程序，可以产生出比较真实的正弦波、三角波以及锯齿波，用VHDL程序编写，有modelsim仿真textbench程序(On EDA experiment, oneself write the NCO program, can produce more real sine wave, triangular wave and sawtooth wave with VHDL programming, have the modelsim simulation textbench program )

数字钟vhdl实现，在线测试无误，具有闹钟，对表功能(Digital clock vhdl implementation, online testing is correct, with alarm, the table function)

5分代码及说明，verilog代码，几乎所有的IC面试都会问到这个问题，所以总结了一下发了上来，共同学习！-5 pm code and explanations verilog code Almost all the interviews will IC asked this question, summed up in the ranks about fat, learn together!

altera的关于对数计算的IP core。-altera calculated on the logarithm of the IP core.

说明：  这个事VHDL基础知识，内面主要内容是编码器的插V过程，值得下载学习！(it is really useful for those who never touch it!)

VHDL小程序（本人的一些小成绩哦，希望对大家有帮助）-VHDL small programs (some of my small achievements Oh, we want to help)

使用Verilog编写的正弦波生成工程，使用ROM核产生，利用mif文件(Written using Verilog sine wave generation projects using ROM nuclear generation, use mif file)

FPGA中嵌入8051的核 并且实现控制128*64的液晶显示-FPGA embedded in 8051 and to achieve control of the nuclear 128* 64 LCD

说明：  关于地铁售票的一些功能 基于自动买票的VHDL设计程序 比较经典(Subway ticket on some of the features of the VHDL-based auto-buying classic design procedure)
