Verilog 编写的网卡DM9000A的IP核，altera公司寄的DE2系统中的源程序核...

设计一个简单的FIR滤波器，并按要求确定滤波器的系统函数。(Design a simple FIR filter, and determine the filter according to the requirement of system function.)

包含UART口的VERILOG源程序，该程序在FPGA上验证通过，可作为芯片设计，或FPGA设计的一个完整IP核，硬件设计的兄弟们可参考一下。-include UART port of VERILOG source, the program tested in FPGA, as chip design, or FPGA design of a complete IP cores, hardware design brothers can make reference.

基于fpga的物理不可克隆函数（PUF）模块的实现(A PUF Design for Secure FPGA-Based Embedded Systems)

基于FPGA的UDP硬件协议栈， 全部用SystemVerilog写的，不需CPU参与，包括独立的MAC模块。 支持外部phy的配置，支持GMII和RGMII模式。 以下是接口 input clk50, input rst_n, /////////////////////// //interface to user module input [7:0] wr_data, input wr_clk, input wr_en, output wr_full, output [7:0] rd_data, input rd_clk, input rd_en, output rd_empty, input [31:0] local_ipaddr, //FPGA ip address input [31:0] remote_ipaddr, //PC ip address input [15:0] local_port, //FPGA port number //interface to ethernet phy output mdc, inout mdio, output phy_rst_n, output is_link_up, `ifdef RGMII_IF input [3:0] rx_data, output logic [3:0] tx_data, `else input [7:0] rx_data, output logic [7:0] tx_data, `endif input rx_clk, input rx_data_valid, input gtx_clk, output logic tx_en(UDP hardware stack, written in system verilog, do nt need CPU.Projgect includes MAC Layer,support phy configuration.support gmii and rgmii mode. the interface is as the follows: input clk50, input rst_n, /////////////////////// //interface to user module input [7:0] wr_data, input wr_clk, input wr_en, output wr_full, output [7:0] rd_data, input rd_clk, input rd_en, output rd_empty, input [31:0] local_ipaddr, //FPGA ip address input [31:0] remote_ipaddr, //PC ip address input [15:0] local_port, //FPGA port number //interface to ethernet phy output mdc, inout mdio, output phy_rst_n, output is_link_up, `ifdef RGMII_IF input [3:0] rx_data, output logic [3:0] tx_data, `else input [7:0] rx_data, output logic [7:0] tx_data, `endif input rx_clk, input rx_data)

关于vhdl的一些例子-on some of the examples of VHDL

基于IP核RAM的同步fifo设计，工程使用Xilinx的开发软件ISE(RAM-based synchronization fifo IP core design, engineering, software development using Xilinx ISE)

高通滤波器的仿真（由matlab和simulink两种方法实现）源文件以及图片示例(Simulation of the high-pass filter (implemented by the two methods matlab and simulink) source files as well as images example)

用fpga芯片使用vhdl语言对AD转换芯片ADC0809进行控制(Using the fpga chip use language of VHDL AD transform chip ADC0809 control)

FPGA开发PCIe的源码，采用VHDL语言，通过此源码，能更好的掌握PCIe总线，使开发者少走弯路，
