随着超大规模集成电路的时钟系统结构日趋复杂，如何清晰明了地表示时钟结构和相互关系成为了业界关注的焦点。本文提出一种图形化显示分析时钟系统结构的方法，在一个图形窗口内即能显示时钟系统的整体结构：利用树型时钟列表表示时钟之间的相互关系；利用标尺指示时序信息和逻辑层次；在显示单元连接关系的时钟结构中，利用符号突出特征单元和特征属性，支持不同颜色高亮显示检查结果以及关键字的查询结果。模块化的抽象方法采用过滤了复杂时钟系统中的次要信息，突出时钟的代表性结构特点，从而有效地化简了主窗口的显示内容。

With the increasing complexity of VLSI clock system, how to display and analyze the clock structure clearly and easily becomes the focus of the industry. This paper presents a methodology of graphical display and analysis of the whole clock system structure in a single GUI window： tree-style clock list region presents the relations among clocks; ruler regionprovides the indication of timing and logic level information; clock structuresare displayed using symbol and modularity, to show the clock prominent features and characteristics, with support of different colors highlight for analysis results and keyword query results. Modular abstraction methods have been adopted, which have greatly simplified the main window display contents.
