ep2c5 实现 逻辑门 verilog语言，quartus 2 仿真

这是一个讲究的的 介绍VB在犀牛软件里的 很好的东西 你会满意的 相信我(you will be glad)

说明：  1、能正确显示输入信号频率； 2、测量频率范围为1Hz ~ 999999Hz； 3、测量结果以十进制数字显示； 4、能测量幅值较小的信号频率； 5、有自动刷新输出数据的功能（如5s刷新一次）； 6、有自检模块（如产生100Hz的校准方波）；(1. It can correctly display the input signal frequency; 2. The frequency range of measurement is 1Hz ~ 99999hz; 3. The measurement results are displayed in decimal; 4. It can measure signal frequency with small amplitude; 5. It has the function of automatically refreshing the output data (e.g. once in 5S); 6. Self checking module (such as generating 100Hz calibration square wave);)

这是一个用VHDL语言描述的I2C自动配置模块，使用了来自opencores.org的I2C核，已在altera的cyclone芯片上调试通过-This is a VHDL language used to describe auto-configuration of the I2C module, the use of the I2C from opencores.org nucleus, the cyclone in the altera-chip debugging through

multisim 程序 使用教程 详细明了清楚(multisim tutorial program uses more clearly understand)

针对兆瓦级风电并网逆变器主电路研制中存在的并联扩容、开关频率较低和LCL滤波器难以优化设计等问题，提出了采用交流侧串接电感再进行并联的均流方案，采用载波移相技术提高变流器的等效开关频率，提出了LCL滤波器的设计原则，并给出了上述设计的理论依据和实现方法。通过对2兆瓦风电变流器主电路的仿真验证了上述技术方案。(MW-class wind power for grid-inverter main circuit of the parallel development of existing capacity, a lower switching frequency and LCL filter design difficult to optimize the problem, a series inductor AC side in parallel are further flow program, the use of carrier phase-shifting technology to enhance the equivalent converter switching frequency, a LCL filter design principles, and gives the above-mentioned theoretical basis for the design and implementation. 2 MW of wind power converter main circuit simulation program to verify the above-mentioned technology.)

FFT VHDL code

设计的结构是纹波进位加法器，但执行的操作是加法和减法，两种操作都是32位的，具体取决于控制信号。如果控制信号为“1”，则选择减法，然后选择“0”，然后选择加法
