本文首先提出了软件复用是当今提高ＩＣ－ＣＡＤ领域中软件的高效率和实用性的一种重要方法，叙述了它在ＩＣ－ＣＡＤ领域中的应用前景；接着在此基础之上给出了一个ＩＣ软件复用系统的模型，并认为ＩＣ－ＣＡＤ领域中的软件标准化可以通过这样的系统而得以实施与推广。然而，本文就软件复用实施过程中的三个瓶颈问题──外来软件实例的理解和软构件的特征提取、软构件库的结构和软构件的获取、系统在软构件基础之上的综合过程，给出了它们在ＩＣ－ＣＡＤ领域中的可行的途径。这些方法已经部分在ＩＣ－ＣＡＤ软件工具开发及系统集成的集成化环境ＩＣＳＤＥ（ＩＣ－ＣＡＤＳｏｆｔ－ｗａｒｅＤｅｖｅｌｏｐｍｅｎｔＥｎｖｉｒｏｎｍｅｎｔ）系统中实现。
This paper first proposes that software reuse is an important method to improve the efficiency and practicability of software in the field of IC-CAD and describes its application prospect in the field of IC-CAD. Based on this, An IC software reuse system model, and that the software in the IC-CAD standardization can be implemented through such a system and promotion. However, this paper discusses three bottlenecks in the implementation of software reuse: the understanding of foreign software examples and the feature extraction of software components; the structure of software component libraries and the acquisition of software components; the synthesis process of system based on software components , Given their feasible ways in the field of IC-CAD. These methods have been partially implemented in ICSDE (IC-CADSoft-wareDevelopmentEnvironment) of IC-CAD software tool development and system integration.
