摘要
为了克服传统中小规模电路进行数字电路实验时所用元器件多、效率低的问题,设计了基于EDA技术的数字电路实验系统,其主芯片采用EPM240T100C5,外围电路包括系统复位电路、蜂鸣器接口电路、4个独立按键接口电路、4个流水灯电路、2位数码管电路、VGA接口电路和RS232串口电路,该系统能实现组合逻辑电路和时序逻辑电路及常见的数字系统,同中小规模电路数字电路系统相比可以有效提高实验效率.
In order to overcome the weakness of much component and lower efficiency medium and small scale integrated circuit in experimentation, a digital electric circuit system is designed based on EDA technology. EPM240T100C5 is used in the system as main chip,and it contains system reset,buzz- er,4 independent keys,4 Water lamp,2 Nixie tube,VGA interface circuit and RS232 interface circuit. The assembly logic circuit and the sequential logical circuit can be realized by the system. The efficiency is improved in this system than that in the medium and small scale integrated circuit in traditionary.
