基于VHDL的点阵控制

用vhdl实现脉冲宽度可控的一简单程序 仿真环境MAXPLUS-(use VHDL to achieve controllable pulse width of a simple process simulation environment Segments-)

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.)

采用VHDL语言编写，此题为全国大学生电子设计竞赛题目，产生一个伪随机信号，并用时钟提取模块提取时钟，最终能在示波器上获得眼图，验证实验结果。此程序已经经过本人亲自验证，完全可用，可用于电赛培训之中。
