Abstract

The invention relates to a method for extracting connection relationships of different modules in a layout, which is realized by extracting connection relation information between modules through validation tool Calibre LVS, The method mainly comprises the following steps: two or more modules which need to extract connection relation are called in and opened by using integrated circuit layout editing tool; the label inside the module adopts distinguishable label and ensures that its interior passes through LVS; A connection line between each cell of the module is added in the operation interface; the label inside the module is copied to the position corresponding to the connecting line between the modules; the calibre authentication tool is started to perform the LVS check; Based on the result of this check, the script file is written with the file top.LVS.report.shorts, which can be used to count and extract the connection relationship between the modules mentioned above. The method used in the invention has high efficiency and accuracy.

Description

technical field [0001] The invention relates to the field of integrated circuit layout design, in particular to a method for extracting the connection relationship of different modules of the layout. Background technique [0002] The integrated circuit board diagram is an intermediate link between the circuit system and the integrated circuit process, and is an indispensable and important link. Through integrated circuit layout design, the three-dimensional circuit system can be transformed into a two-dimensional plane figure, and then restored to a three-dimensional structure based on silicon materials after processing. [0003] The Caliber verification tool, when comparing the layout with the design drawing, usually thinks that a connection (net) has a unique label (label). If different labels appear on the same connection, the caliber verification tool will think that you put two The connections that should not be connected together are wrongly connected together. This m...
