摘要
随着当今电子行业的发展,对SoC芯片,尤其是数模混合芯片的要求越来越高。和传统的DEF/GDS数据交互方式相比,Mixed Signal Open Database(MSOA)RapidPDK可以帮助设计人员通过相同的PDK更好地完成数字工具Innovus和模拟工具Virtuoso之间的数据传递。首先描述了5 nm MSOA RapidPDK生成方式,其次使用生成的PDK实现5 nm IP物理实现,同时验证MSOA flow对5 nm设计在版图完成和交付方面的速率提升。
Success in today′s electronics market place,most SoCs currently being developed have analog or mixed signal blocks,many so-called analog blocks actually have digital-control logic.Virtuoso-innovus flow with MSOA RapidPDK allows for all or parts of the physical hierarchy to pass back and forth between Virtuoso and Innovus easily without having to generate a DEF/GDS file.In this paper,we firstly describe the way to generate 5 nm RapidPDK,then use this PDK with digital flow to finish 5 nm IP design with custom lib.Additionally,this Virtuoso-innovus flow provides our analog designers with advanced techniques for 5 nm floorplanning,pin optimization,track generation and auto place&routing with RC extraction and timing analysis aware which will simplify the flow to enable virtuoso users to run 5 nm layout implementation,and also could help us to do full chip STA analysis.
