    • In a graphic layout compaction system for compacting a layout where components and routes are placed on a two-dimensional space, a terminal graph generator prepares terminal graph data indicative of terminal graphs having component terminals as nodes. The terminal graph generator calculates, as a movement amount for allowing a first component terminal to come near a second component terminal, a movement limit area within which the first component terminal can move in any directions towards the second component terminal in consideration of a route bandwidth interposed therebetween. A component compactor moves the first component terminal on a position where the first component terminal is not interfered with the movement limit area. A rerouting unit shapes routes into shaped routes having configurations including oblique parts to reroute the shaped routes in a space between the first and the second component terminals.
    • 在用于压缩其中组件和路线放置在二维空间上的布局的图形布局压缩系统中,终端图生成器准备表示具有组件终端的端子图作为节点的终端图形数据。 端子图生成器计算作为第一分量终端接近第二分量终端的移动量,考虑到路线带宽,第一分量终端可以朝向第二分量终端向任何方向移动的移动限制区域 插入其间。 部件压实机将第一部件端子移动到第一部件端子不受移动限制区域的干扰的位置。 重新路由单元将路线形成为具有包括倾斜部分的配置的成形路线,以在第一和第二组件终端之间的空间中重新路由成形路线。
