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

用VHDL语言编写的LDPC码硬件实现语言，相对于verilog的，比较简单-Using VHDL language LDPC code hardware implementation language, compared to Verilog, and relatively simple

说明：  简单的一个Verilog小程序，适合刚接触的人群(A simple Verilog small program, suitable for people just contact)

that file is different I2S example

verilog代码，串口发送接收代码，含有源代码和测试文件，准确可用(verilog code for serial port transmit and receive code, with source code and test files, and accurate available)

A 4 bit twisted ring counter is a sequential circuit which produces the following sequence of output values: 0000, 1000, 1100, 1110, 1111, 0111, 0011, 0001 and then repeats. Design a circuit for a 4 bit twisted ring counter that uses four D flip flops. Draw a state transition diagram, a state table and a schematic for your circuit. Design an alternate implementation using just three flip flops and draw a state transition diagram, state table and a schematic for your circuit. If your designs are extended to implement an n bit twisted ring counter, how many flip flops are required using each of the two approaches. In what situations would you prefer the first method? In what situations would you prefer the second?

verilog jtag源码及原理，还有debug模块。边界扫描等(verilog jtag source and principle, as well as debug module. Boundary-Scan, etc.)

测量周期,此程序已经在EP2C板子上成功实现(mesure cycle)

QuartusII简介手册+中文版 本手册针对的读者是 Quartus II 软件的初学者，它概述了可编程逻辑设计中 Quartus II 软件的功能。 不过，本手册并不是 Quartus II 软件的详尽参考手 册。 相反，本手册只是一本指导书，它解释软件的功能以及显示这些功能如 何帮助您进行 FPGA 和 CPLD 设计。-QuartusII brochure+ Chinese version of the manual is aimed at readers of Quartus II software for beginners, it provides an overview of programmable logic design in Quartus II software. However, this manual is not the Quartus II software, a detailed reference manual. Instead, this manual is a guide book, which explained the functions of the software and show how these features help you to FPGA and CPLD design.

VHDL实现了IIS接口程序，在Quartus II 6.0上编译通过，在板子上可以读取IIS数据-IIS VHDL interface procedures, the Quartus II 6.0 compiled by the board can read data IIS
