VHDL源代码包

利用Cadence Allegro PCB SI进行SI仿真分析(Performed using the Cadence Allegro PCB SI SI simulation analysis)

SPI串口的内核实现（vhdl）,可以用qII等软件直接加到FPGA或者CPLD里面.-the SPI Serial Kernel (vhdl) can be used directly qII software foisted CPLD or FPGA inside.

SDRAM基础性控制核 很有用的 VHDL状态机实现-SDRAM control of the nuclear basic useful VHDL state machine implementation

vhdl random numbergenerater

用Verilog HDL编写的PID程序代码，成功调试，运行良好。(The source code of PID in Verilog HDL.Simulation was successful.)

说明：  32位/33M 从模式(target)PCI接口参考设计，Lattice提供。由于PCI时序较复杂，此设计仅能供参考(32/route from the model (target) PCI reference design, Lattice provided. Because PCI timing more complicated, and the design for reference only)

这是本人自己编写的可用于256*256大小的图像进行sobel边缘检测的vhd文件，可在QuartusII或MaxplisII下综合和仿真，并在FPGA上测试过。可以进行修改支持其他大小图像的sobel边缘检测，同时还可以实现其它的图像模块化处理算法，例如高斯滤波，平滑等。(this is my own preparation for the 256* 256 size of the image segmentation Edge Detection vhd document in the next QuartusII or MaxplisII integrated and simulation, and the FPGA tested. Can be adapted to support other size image segmentation edge detection, It can also achieve other modular image processing algorithms, such as Gaussian filtering, smoothing and so on.)

基于Verilog的串口通信源码 ，实现串口通信功能(Verilog source code based on serial communication)

FPGA——IP_RAM实验： 创建IPRAM核，单端口，10位地址线（256字节），8位数据线（每字节8byte），读写使能 input [9:0] address; input clock; input [7:0] data; input wren; //置1则写入 output [7:0] q; LNXmode：控制LEDC显示 1：mode1，从k1~k3输入data的低4位，ledb计时，从0~f，计时跳变沿读取k1~k3的值，存入RAM 8个数之后，从RAM输出数据，用leda显示，同样每秒变化一次(The experiment of FPGA-IP_RAM: Create IPRAM core, single port, 10 bit address line (256 bytes), 8 bit data line (8 byte per byte), read and write enablement)
