摘要： Particular embodiments generally relate to automatic routing of a bus in an integrated circuit design. In one embodiment, a method includes receiving a description of a circuit design. Buses are automatically detected based on pin adjacency in terms of distance between pins and routing layer of the pins. A bus routing area is determined by the bounding box of first group of source pins and a second group of destination pins. Bus routing guidance is then generated by an automatically search engine in the bus routing area. The bus routing guidance models a bus as a skinny wire with large spacing, and it does not violate design rules. Real bus wires are generated based on the bus guidance. A bus is then automatically routed between a first group of source pins and a second group of destination pins based on the bus routing guidance.
摘要翻译：具体实施方案通常涉及集成电路设计中总线的自动布线。在一个实施例中，一种方法包括接收电路设计的描述。根据引脚和引脚的布线层之间的距离，基于引脚邻接自动检测公共汽车。总线路由区域由第一组源引脚的边界框和第二组目标引脚确定。然后由总线路由区域中的自动搜索引擎生成总线路由引导。公共汽车路线指导将总线建模为具有大间距的瘦线，并且不违反设计规则。根据总线指导产生实线总线。然后，基于总线路由引导，总线在第一组源引脚和第二组目标引脚之间自动布线。
