很好的fft学习程序感兴趣的同学可以看哈，下载一下。(it is very good )

Test for VHDL just a student version

VERILOG HDL pid算法 带仿真验证(pid by verilog HDL)

最大值求解是利用System Generator平台实现的比较方便不用自己写verilog代码就可以在Xilinx平台下使用，非常方便实用！

说明：  实现主干道交通灯显示，以状态机程序实现，并用数码管进行红绿灯倒计时的显示，内置计数模块，交通灯控制模块，数码管显示模块，并对各模块用电路图的方式进行连接。对于学习VHDL语言有所帮助。(The main road traffic light display is realized by the state machine program, and the digital tube is used to display the traffic light countdown. The counting module, the traffic light control module and the digital tube display module are built in, and each module is connected by the circuit diagram. It is helpful for learning VHDL.)

verilog hdl 编写的64点fft代码，适合很多芯片(coded by verilog hdl that implement 64 point fft, suite to many core)

用verilog实现对三个16位数进行相加乘法器(Three 16-digit sum of the multiplier Verilog)

异步串行传输的verilog hdl 功能文件以及测试文件(The verilog hdl source and the testbench of asynchronous serial transmission )

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)
