Integrated circuit semi-custom physical design penetration signal line automatic planning method

Abstract

The invention discloses an integrated circuit semi-custom physical design penetration signal line automatic planning method, comprising the following steps: Step S1: Obtain the original design data and judge the correctness of the original design data. If the judgment is passed, the step S1 is executed; otherwise, the step S1 is executed repeatedly. 2, carry out automatic planning of that pas signal line according to the original design data. 3, derive a through signal line planning result file accord with that format prescribed by the EDA tool and a report file for subsequent analysis, judging whether the through signal line plan result file conforms to the requirement, and executing a subsequent flow if the judgement is passed, otherwise repeatedly executing the step S1. The invention discloses an integrated circuit semi-custom physical design penetration signal line automatic planning method, which has the characteristics of short FeedThrough path, moderate number of sub-module pins, good FeedThrough symmetry and the like, and can improve the design efficiency of penetration signal line.

Description

technical field [0001] The invention belongs to the technical field of integrated circuit design automation, and in particular relates to an automatic planning method for integrated circuit semi-customized physical design through signal lines. Background technique [0002] As the scale of the chip becomes larger and larger, a top-down design method has to be used to divide the chip into different sub-modules, so that the original timing path is distributed in different sub-modules, causing each sub-module to be different from the Other submodules generate connection relationships. Since there will be millions of connection lines between different sub-modules in the chip, the FeedThrough (through signal line) planning of the chip is an important part of the entire back-end design process. [0003] At present, various design companies do not optimize the design during the FeedThrough planning process, which leads to problems such as poor design results and long design cycles,...

Problems solved by technology

[0003] At present, various design companies do not optimize the design during the FeedThrough planning process, which leads to problems such as poor design results and long design cycles, which eventually lead to delays in the development cycle of the project or even unacceptable

In the conventional FeedThrough planning method, there is no effective general method to improve the result quality of FeedThrough planning, so it is a technical problem that needs to be urgently solved in the current status of semi-customized back-end design
