实用化逻辑图快速显示及部分图形管理关键技术的研究

摘要

提出了三级图形缓冲显示技术，不仅有效地解决了大规模逻辑图的快速显示问题，而且保证了图形滚动的连续性；还论述了部分图形管理功能的实现方法，针对逻辑图的特点，提出了将矢量存储与逻辑符号图形库相结合的存储策略，解决了逻辑图存储中占用空间大、不易存彩色等问题.%The display technique with three|level buffer proposed in this paper has not only solved the problem of high|speed display for large schematics but also ensured scrolling smoothly. The implementation of graphics management is also discussed. Combining the vector storage with graphics library of logic cell can save the storage space and reserve the color.
