摘要: 隨著當今電子行業的發展,對SoC芯片,尤其是數模混合芯片的要求越來越高。和傳統的DEF/GDS數據交互方式相比,Mixed Signal Open Database(MSOA) RapidPDK可以幫助設計人員通過相同的PDK更好地完成數字工具Innovus和模擬工具Virtuoso之間的數據傳遞。首先描述了5 nm MSOA RapidPDK生成方式,其次使用生成的PDK實現5 nm IP物理實現,同時驗證MSOA flow對5 nm設計在版圖完成和交付方面的速率提升。

Abstract: 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
Key words : MSOA RapidPDK;5 nm;Virtuoso;Innovus

隨著芯片工藝的發展,數模混合芯片中的數字和模擬模塊(Block)已經沒有明顯的區分界限,很多情況下,模擬模塊的內部會包含數字模塊,隨之而來的問題是需要大量時間和精力解決在數字和模擬模塊之間數據交互的問題和彼此database的兼容性。同時先進工藝下隨著double pattern等特性的引入,模擬版圖的實現變得更加復雜,而如何提高效率,保證數據準確性也變得更加重要。
