说明：  quartus vitual jtag代码使用接口，通过该接口模板方便使用者通过jtag在线读取FPGA的数据。(The quartus virtual JTAG code uses an interface, through which users can read FPGA data online.)

说明：  利用Verilog语言实现PID增量式控制，输出占空比(Using Verilog language to realize PID incremental control and output duty cycle)

以上是VHDL硬件描述语言写的一个简单锝路流水灯程序,希望对刚接触VHDL的朋友有一定帮助-These are the VHDL hardware description language written in a simple flow path lights technetium procedures,刚接触VHDL want to have some friends to help

全自动洗衣机的控制器。 1.洗衣机的工作步骤为洗衣、漂洗和脱水三个过程，工作时间分别为：洗涤10秒，漂洗5秒，脱水5秒； 2.用一个按键实现洗衣程序的手动选择：A、单洗涤；B、单漂洗；C、单脱水；D、漂洗和脱水；E、洗涤、漂洗和脱水全过程； 3.用显示器件显示洗衣机的工作状态（洗衣、漂洗和脱水），并倒计时显示每个状态的工作时间，全部过程结束后，应提示使用者； 4.用一个按键实现暂停洗衣和继续洗衣的控制，暂停后继续洗衣应回到暂停之前保留的状态； (Automatic washing machine controller. 1 washing machine work steps for the laundry, rinsing and dehydration three processes, working hours are as follows: washed for 10 seconds, rinse for 5 seconds, dehydrated five seconds 2 with a button to manually select the program to achieve laundry: A, single-washing B, single rinse C, a single dehydration D, rinsing and dehydration E, washing, rinsing and dehydration the whole process 3 with a display device display the working status of washing machine (laundry, rinsing and dehydration), and each state countdown show working hours, after the whole process should prompt the user 4 laundry with a button to pause and continue control of laundry, laundry should be back after a pause pause before continuing to retain the state )
