UVM SV阶段

本程序是VGA256色方块显示的verilog HDL代码，包括XILINX系列virtex5 FPGA芯片的约束程序，用相应的板子连上VGA接口到显示屏上可以实现显示，显示分辨率1024×768，包括行场同步信号消隐程序、有效区域显示和256色VGA显示程序，代码安全可靠。

一个9层电梯的代码。每层电梯入口处，要求开关1，电梯内设有乘客到达的停止开关的水平。（没有下降的按钮，一楼九楼没有上行键）

The red arrow showed the output became 8 when the measured temperature changed to 11°C. As shown by black arrow, the maximum output was 28. The program was run according to the proposed method.

HDMI做为视频输出输入接口已经广泛使用很长时间，主要通过TMDS差分编码传输。本实验通过在HDMI屏幕上显示彩条和输入输出环通实验，来练习视频的时序和视频颜色的表示，为后面视频处理实验做个基础。(HDMI as video output input interface has been widely used for a long time, mainly through TMDS differential coding transmission. In this experiment, by displaying color bars and input/output loop experiments on HDMI screen, video timing sequence and video color representation are practiced to lay a foundation for video processing experiments later)

verilog语言实现的cordic算法，计算sin cos三角函数

基于xilinx公司的Basys2开发板开发的FPGA数字钟，实现了时钟、闹钟和秒表等功能,同时包含了测试程序。使用Verilog语言编写，开发软件为Xilinx ISE Design Suite 13.4。

ADS7809是Burr-Brown公司推出的高精度AD采集芯片。它采用5V单电源供电,内含16位 逐次逼近寄存器,采样精度高,功耗小。 用Verilog实现其配置(ADS7809 is a Burr-Brown Introduces High Precision AD capture chip. It uses a single 5V supply, with 16-bit successive approximation register, sampling and high precision, low power consumption. To achieve its configuration with the Verilog)

主要编写了一组二进制数据通过根升余弦滤波器后的波形，但并没有使用ISE内部的FIR滤波器内核，该程序相当于编写了一个根升余弦滤波器。(Mainly prepared a set of binary data through the root raised cosine filter waveform after, but did not use the ISE internal FIR filter kernel, the program is equivalent to the preparation of a root raised cosine filter.)

ASK调制信号的verilog VHL设计，在ise中实现了ASK信号的调制解调。(ASK modulation signal verilog VHL design, in ise to achieve the ASK signal modulation and demodulation.)
