XCZ7035的硬件平台使用说明 包括USB接口(XCZ7035 hardware platform instructions Including USB interface)

8b10b编码方式，verilog语言实现，有测试程序。能成功编码。没有环回验证，读者可自行编写环回验证测试程序。(8b10b encoding, verilog language, test procedures. Successful encoding. No loopback verification, readers can write your own loopback verification test procedures.)

有用的数字钟设计文档，有秒表、闹钟等模块，希望对大家有用！(JUST LEARN FROM IT!!ENJOY!)

FPGA上的VERILOG语言编程。通过查找表实现直接数字频率合成。在主控部分通过键盘选择正弦波，方波，三角波，斜波，以及四种波形的任意两种的叠加，以及四种波形的叠加；通过控制频率控制字C的大小，以控制输出波形频率，实现1Hz的微调；通过地址变换实现波形相位256级可调；通过DAC0832使波形幅值256级可调；通过FPGA内部RAM实现波形存储回放；并实现了每秒100HZ扫频。(FPGA on the verilog language programming. Lookup table through direct digital frequency synthesis. In part through the control of the keyboard to choose sine, square, triangle wave, sloping wave, and four arbitrary waveform two superposed and the stack of four waveform; by controlling the frequency control word on the size, in order to control the output waveform frequency, 1 Hz to achieve the fine-tuning; Address transform through waveform phase adjustable 256; DAC0832 so through waveform amplitude adjustable 256; FPGA through internal RAM to the waveform storage intervals; and achieve a 100 per second sweep 9999.)

MAX+plus II编译的模30加法计数器，简单的与非门组成！-MAX+ Plus II compiler module adder 30 counters, a simple composition with the non-door!

说明：  实现ARP、ICMP、UDP、TCP、IP和MAC全过程的传输，对TCP的连接、接收、发送、断开均经过测试，功能正常(Realize the transmission of ARP, ICMP, UDP, TCP, IP and MAC in the whole process, test the connection, reception, transmission and disconnection of TCP, and the function is normal)

PLL 锁相环verilog程序 可以直接使用(The PLL can be used directly good use)

基于sopc的7352的ad模块的nios软核多通道编写,verilog 写的(The sopc 7352 AD module nios soft core multichannel write. Rar )

资源描述VGA视频图形阵列（VGA）接口是一三排15针de-15连接器。15针VGA接口是许多视频卡，发现电脑显示器，以及一些高清晰度电视机。在笔记本电脑或其他小型设备，迷你VGA端口有时用于全尺寸的VGA接口的地方。
