摘　　要：逆向工程在科技发展和商业用途上都发挥着重要作用。本文针对在电子、电机和信息领域广泛应用的可编程逻辑器件进行逆向工程研究,首先根据设计中可实现的逻辑结构特征对可鳊程逻辑器件进行分类,分析论证使用非破坏性方法对可编程逻辑器件进行逆向还原、再造的可能性,然后理论证明可编程逻辑器件逆向工程的可行性,最后给出逆向工程分析中所涉及的关键技术。Reverse engineering technology is very important in the development of science and technology and commercial applications. Techniques of reverse engineering of programmable logic devices （PLD） are discussed which are commonly used in electronic, electrical and information industries. First, programmable logic devices are divided into different types according to the designed logic structure. Second, a methodology is developed to demonstrate the feasibility of non-destructive technique for reverse engineering PLDs. Finally, some key techniques in the reverse analysis are presented.
