VGA基础彩条测试实验

说明：  组合时序电路的小例子，移位和数据选择器的代码，以及测试文件(Small examples of combinational sequential circuits, code for shift and data selectors, and test file.)

Quartus环境下使用Verilog编写的HDB3编解码程序，RTL和时序仿真已过(Quartus under the environment of a HDB3 protocol procedures written in Verilog, RTL and timing simulation has be passed)

verilog开发FPGA，实现RS485串口通信(RS485 driver for FPGA )

用VERILOG实现一个被除数为8位、除数为4位的高效除法器(With VERILOG implement a dividend for the 8-bit, 4-bit effective divisor divider)

AHB BUS 的一些接口代码， verilog, 希望对初学AHB总线的兄弟有所帮助。 里面包含 ahb decode, ahb_mux and ahb2mem. 以及相应的验证环境， 此代码只用于学习，如果用于项目，仅供参考。

FPGA 学习实例 动态时钟、面积、速度优化相关代码(Codes related to dynamic clock, area and speed optimization for learning examples of FPGA)

有限状态机工作原理、设计方法、步骤等精要说明(Finite state machine working principle, design method, such as Essentials of steps to explain)

关于I2C总线协议的verilog代码，里面包括了3个verilog代码(I2C bus protocol verilog code, which includes three verilog code)
