i2c总线的工程实现，可以用在altera环境下验证-i2c bus project implementation can be used in altera verification environment

Programmable IIR Filter written in Verilog and its respective modules.

可以实现DDS 的正负线性扫频以及在线参数设置(DDS ad9914/ad9915 code)

电子设计自动化中的计数器的实现程序，基于VHDL语言完成的-Electronic design automation in the realization of counter procedures, based on the VHDL language completed

simple code based on verilog shifter , cla ,clg

verilog编写的数字信号发生器NCO用CORDIC方法实现产生sin cos信号，流水线结构，简单实用。(verilog prepared by the digital signal generator NCO using CORDIC method implementation generate sin cos signal, pipelined architecture, simple and practical。)

VHDL库，仿真时使用的，包括打印，类型转换等实用的操作(Practical operation VHDL library, using simulation, including print, type conversion, etc.)

这是一个利用verilog语言编写的信号发生器的例子，值得参考(this is a code about signal generator by VIERILOG LANGUAGE!)
