摘　　要：为了降低装备维修器材的筹措难度,提高应急条件下维修保障的实时性、快速性,研究适合在部队维修分队推广使用的集成数字器件通用代换技术。采用超小型或小型封装的可编程器件CPLD,焊接到特制的DIP封装的托座上,形成待编程的集成电路。在ISP Lever开发环境下结合原理图和硬件描述语言设计各种常用数字集成电路,完成数据库的开发。这样便可以在应急条件下根据现场需要调用数据库中目标文件,将其下载到可编程芯片中,使之替换损坏的原集成数字器件。In order to reducing the collection difficulty of repair equipment,improving the real time and speediness of servicing,the replacement technology of digital integrated device is researched based on army servicing.The study introduced the subminiature and pint-size encapsulation CPLD,which was welded to the tailor-made seat of DIP encapsulation,and formed the integrated circuit that pending programmed.Based on the ISP Lever and introduce the principium chart and hardware description language,various digital integrated circuit and form the data-base are designed.So in the emergency,the bad device can be replaced by download the data-base procedure to the CPLD.
