北大verilog课件，数字集成电路设计入门，从HDL到版图

一般网站上都有i2c master模块的代码,但很少有slave的代码,这里就是slave的代码,非常有用.-general website have i2c master module of code, but very few slave code, This is the slave code, very useful.

使用FPGA控制AD9288，方便移植，可以拿来直接使用，适合新手学习(Use FPGA control AD9288, easy migration, can be used to directly use for novices to learn)

  基于FPGA(Field-Programmable Gate Array)的OFDM(Orthogonal Frequency Division Multiplexing)信号传输系统VHDL源码 use IEEE.std_logic_unsigned.all; package outconverter is constant stage : natural := 3; constant FFTDELAY:integer:=13+2*STAGE; constant FACTORDELAY:integer:=6; constant OUTDELAY:integer:=9; function counter2addr( counter : std_logic_vector; mask1:std_logic_vector; mask2:std_logic_vector ) return std_logic_vector; function outcounter2addr(counter : std_logic_vector) return std_logic_vector; end outconverter; package body outconverter is function counter2addr( counter : std_logic_vector; mask1:std_logic_vector; mask2:std_logic_vector ) return std_logic_vector is variable result :std_logic_vector(counter"range); begin for n in mask1"range loop if mask1(n)="1" then result( 2*n+1 downto 2*n ):=counter( 1 downto 0 ); elsif mask2(n)="1" and n/=STAGE-1

vhdl 实现fpga 闪灯控制 流水线闪灯 还用signalTAP进行检测，给初学者参考(vhdl fpga flash control lines to achieve flash is also used signalTAP testing, to advanced users)

ep2c5 实现 段寄存器,实验一 verilog语言，quartus 2 仿真-Register ep2c5 achieve above experiment a verilog language, quartus 2 Simulation

包含32为乘法器的设计，用verilog语言实现，包括booth编码的实现，booth乘法器的实现，3_2压缩器的实现，4_2压缩器的实现，华伦斯树的实现，以及两个testbench文件用于测试。(Contains 32 multiplier design, verilog language, including booth encoding implementations, booth multiplier implementations, 3_2 compressor implementation 4_2 compressor to achieve and realize China Clarence tree, and two testbench file with the to the test.)

用Vrilog产生一个混沌信号，并用MATLAB仿真，画出波形。(With Vrilog generate a chaotic signal simulation using MATLAB, draw the waveform.)

一位LED显示的VHDL程序，挺简单的，买的开发板里面带的-An LED display of the VHDL program, quite simply, to buy development board inside the zone

自动售货机，根据所要的东西，自动收费，并进行找零(Vending machine, according to what you want to automatically charge and conduct Keep the change)

说明：  qpsk的fpga实现，包含调制和解调部分，使用verilog语言(FPGA implementation of QPSK)
