VERILOG比较器设计

verilog代码实现的数字密码锁。通过4个并行的10位移位寄存器，分别记录在时钟上升沿时A,B,C,D的输入情况，比如某上升沿输入A，相应时刻A对应的移位寄存器输入1，其他三个移位寄存器输入都为0.另外4个并行的10位寄存器记录密码。这样，密码锁不仅可以识别字符数量，还可以判断出字符的输入次序。(verilog code of digital lock. By four parallel 10-bit shift register, respectively, recorded in the clock rising edge A, B, C, D of inputs, such as a rising edge of input A, the corresponding moments A 1 corresponding to the input shift register, the other three shift bit register inputs are 0. another four parallel 10-bit registers record the password. This lock can not only identify the number of characters, you can also determine the character of the input sequence.)

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)

说明：  基于CycloneV FPGA与电阻网络的数模转换器代码，能够实现键控更改频率，通过ROM IP核存储波形数据。(Digital to analog converter code based on cyclonev FPGA and resistance network can realize keying change frequency and store waveform data through ROM IP core.)

说明：  针对XILINX 7系列FPGA 中MTG的驱动代码，代码的接口部分主要分为两个部分，一是控制DDR的DMA大小，选择读写，每次DMA的起始地址；二数据部分为AXIS。 已经在多个工程中使用。(For the driver code of MTG in XILINX 7 series FPGA, the interface part of the code is mainly divided into two parts, one is to control the DMA size of DDR, select read and write, the starting address of each DMA; the second data part is AXIS. It has been used in multiple projects.)
