原创，帧同步器的Verilog代码，在FPGA上验证实现过，无误。作为通信系统帧传输的仿真，有限状态机同步态和失步态的切换仿真。(Original Verilog code for frame synchronization, verify the implementation on the FPGA, and correct. Frame transmission as the communication system simulation, finite state machine synchronous state and the loss of the switching simulation of gait.)

开关数据加载到寄存器并显示的设计与实现.3． 设计一个可以把4个开关的内容存储到一个4位寄存器的电路，并在最右边的7段显示管上显示这个寄存器中的十六进制数字。我们使用到去抖动模块clock_pulse， 用btn[0]作为输入；8位寄存器模块，用btn[1]作为加载信号；7段显示管上的显示模块x7segbc；分频模块clkdiv，用以产生模块clock_pulse和x7segbc的clk190时钟信号。(Design of switching data is loaded into the register and display the.3. design and implementation of a 4 switch content storage circuit to a 4 bit register, and in the 7 section of the most on the right shows the register in the sixteen decimal digital display tube. We used to go to the jitter module clock_pulse, with btn[0] as the input 8 bit register module, as the loading signal by btn[1] 7 segment display module on the x7segbc pipe frequency module clkdiv, clk190 clock signal for generating module clock_pulse and x7segbc.)
