摘　　要：用VHDL语言在CPLD器件上实现了一种模拟跑步机的状态控制,能够用LCD显示屏实时显示各种状态信息.介绍了跑步机电路的设计方法,用状态机的方式实现和转换跑步机各种功能,并给出了状态机的功能仿真波形图.将跑步机功能的设计集成在一块CPLD芯片上,具有体积小、可靠性高、功耗低的特点.由于采用模块化的设计,对功能的修改和增加只要修改VHDL源程序,而不必更改硬件电路,从而实现数字系统硬件的软件化.A state control of simulated treadmill was implemented using VHDL in the CPLD, and the information of all states could be displayed on LCD screen in real-time. The design method of treadmill circuit was introduced. The state machine was used to achieve and converse the functions of treadmill and the functional simulation waveform was also given. The functions of treadmill were designed on a CPLD chip, which has the characteristics of smaller, higher reliability and lower power consumption. Owing to modular design, VHDL program could be amended to add functions without changing hardware circuits, so the digital system could be realized by software.
