【摘要】 针对当前EDA工具存在的弊端,提出了一种审查PCB设计正确性的方法和实现方案。根据实现方案,设计了审查通用数据结构。PCB数据结构的建立实现了异构EDA工具数据的融合和规范化。此外,针对PCB版图特有的复杂性,提出了一种面向审查的分区算法。通过在Cadence/Allegro与Innoveda/PowerPCB上的跨平台试用,验证了该数据结构的建造及审查实现算法非常实用和高效。更多还原

【Abstract】 To overcome the limitation of the current EDA tools,a way for verifying the PCBs after placement and routing is put forward.According to the way,the datastruct based on the verifying is designed.The construction of the PCB data structure makes different data of all kinds of EDA tools unified and shared.At the same time ,a new blocking algorithm is described according to the complexity of the PCBs.The experiment result proves that the data structure and the blocking algorithm are of high practicality and effectivity.更多还原
