摘要： Roughly described, while manually dragging shapes during IC layout editing, editing operations determine which edges of which shapes are moving at what speed ratios. Based on the edge information and the DRC rules, the system calculates and keeps track of the minimum of the maximum distance the edges are allowed to move with the cursor without violating DRC rules, in four linear directions and all corner directions. Once a next cursor destination point is known, a DRC clean destination point is calculated based on the linear and corner bounds. If the next cursor position is beyond a the push-through distance ahead of the new DRC clean point, the editing objects are moved to the user's destination point. Otherwise, the editing objects are moved to the new DRC clean destination point, thereby stopping movement at that point.

摘要： Roughly described, a design rule data set is developed offline from the design rules of a target fabrication process. A design rule checking method involves traversing the corners of shapes in a layout region, and for each corner, populating a layout topology database with values that depend on respective corner locations. After the layout topology database is populated, the values are compared to values in the design rule data set to detect any design rule violations. Violations can be reported in real time, while the user is manually editing the layout. Preferably corner traversal is performed using scan lines oriented perpendicularly to edge orientations, and scanning in the direction of the edge orientations. Scans stop only at corner positions and populate the layout topology database with what information can be gleaned based on the current scan line. The different scans need not reach each corner simultaneously.

摘要翻译：粗略描述，设计规则数据集是从目标制造过程的设计规则离线开发的。设计规则检查方法涉及遍历布局区域中的形状的角，并且对于每个角，使用取决于各个角位置的值来填充布局拓扑数据库。填充布局拓扑数据库后，将值与设计规则数据集中的值进行比较，以检测任何设计规则违规。当用户手动编辑布局时，可以实时报告违规。优选地，使用垂直于边缘取向定向的扫描线并沿着边缘取向的方向进行扫描来执行拐角穿透。扫描仅在角位置停止，并根据当前扫描线填充布局拓扑数据库，并获取可以收集的信息。不同的扫描不需要同时到达每个角落。

摘要： Roughly described, a system enables quick and accurate depiction to a user of multi-patterning layout violations so that they may be corrected manually and in real time, and without interfering with normal manual editing process. In one embodiment, the system involves iteratively building tree structures with nodes identifying islands and arcs identifying multi-patterning spacing violations between the connected islands. The system detects coloring violations during the building of these tree structures, using the relationships previously inserted. The coloring violations preferably are reported to a user in the form of visual indications of the cycles among the candidate spacing violations, with the candidate spacing violations also themselves indicated visually and individually. The user can see intuitively how to move the islands around, and in which directions and by what distance, in order to remove a multi-patterning spacing violation and thereby break the cycle.

摘要： Roughly described, a design rule data set includes rules on derived layers. The rules are checked by traversing the corners of physical shapes, and for each corner, populating a layout topology database with values gleaned from that corner location, including values involving derived layers. After the layout topology database is populated, the values are compared to values in the design rule data set to detect any design rule violations, including violations of design rules defined on derived layers. Violations are reported in real time during manual editing of the layout. Preferably corner traversal is performed using scan lines oriented perpendicularly to edge orientations, scanning in the direction of the edge orientations. Scans stop only at corner positions on physical layers, and populate the layout topology database with what information can be gleaned based on the current scan line, including information about derived layers. The scans need not reach corners simultaneously.
