verilog实现pwm波

说明：  16位右移位寄存器 下面描述的是一个位宽为16位的右移位寄存器，实际具有环形移位的功能，是在右移位寄存器的基础上将最低位的输出端接到最高位的输入端构成的。其功能为当时钟上升沿到达时，输入信号的最低位移位到最高位，其余各位依次向右移动一位。(16-bit right shift register The following description is a right shift register with a bit width of 16 bits. It actually has the function of circular shift. It is based on the right shift register, which connects the lowest bit output terminal to the highest bit input terminal. Its function is that when the rising edge of the clock arrives, the lowest displacement of the input signal reaches the highest position, and the rest of you move one bit to the right in turn.)

第十章的代码。 本书通过100多个模块实例，详细地讲解了Verilog HDL程序设计语言，全书共分13章，内容涉及VerilogHDL语言基本概念、建模、同步设计、异步设计、功能验证等，实例包括各种加法器/计数器、乘法器/除法器、编码器/译码器、状态机、SPIMaster Controller、I2C Master controller、CAN ProtocolController、Memory模块、JPEG图像压缩模块、加密模块、ATA控制器、8位RISC-CPU等及各个实例模块相应的Testbench，所举实例具有很强的实用性和代表性，每个实例均给出了介绍、功能分析、程序代码和结果演示(Chapter X code. This book by more than 100 module instance, explain in detail the Verilog HDL programming language, the book is divided into 13 chapters, covering basic concepts VerilogHDL languages, modeling, synchronous design, asynchronous design, functional verification, etc. Examples include a variety of additions device/counters, multipliers/dividers, encoders/decoders, state machines, SPIMaster Controller, I2C Master controller, CAN ProtocolController, Memory modules, JPEG image compression module, encryption module, ATA controller, 8-bit RISC-CPU etc. and the various instances of the corresponding module Testbench, The examples are highly practical and representation, each instance of it all gives the introduction, functional analysis, program code and the results demonstrate)

基于NIOS2的VGA接口IP核，具有很好的借鉴性和参考性(NIOS VGA IP)

利用VHDL语言编写的4*4键盘扫描程序，经过测试，可以放心使用。(Using VHDL language 4* 4 keyboard scanning procedures, tested, safe to use.)

说明：  fpga实现相关滤波算法中的CSK算法，采用仿真的方式验证结果 fpga是xilinx 仿真工具是vivado2018.2 语言是verilog(The CSK algorithm is implemented in FPGA, and the results are verified by simulation FPGA is Xilinx The simulation tool is vivado 2018.2 Language is Verilog)

本项目可以使用ip产生正弦或余弦信号核心.if你需要像fsk或psk一样的调制，你可以根据需要改变输入我需要这个如果需要，nco可以产生sin或cos信号。
