Abstract

The invention discloses an integrated circuit semi-custom rear end ECO (electron-coupled oscillator) design method which includes the steps: S1 distinguishing an ECO design requirement into functionalECO design or non-functional ECO design by a rear end design tool, executing a step S2 if the ECO design requirement is the functional ECO design, and executing a step S3 if the ECO design requirement is the non-functional ECO design; S2 judging whether optimization is needed or not according to original ECO data and incremental ECO data, sequentially executing automatic optimization, manual optimization and outputting of a functional ECO design result if optimization is needed, and sequentially executing manual optimization and outputting of the functional ECO design result if not. Accordingto the integrated circuit semi-custom rear end ECO design method, integrated chip rear end design efficiency is improved, invalid working is effectively avoided, design iteration frequency is reduced, a chip design period is shortened, and the method is suitable for rear end design projects with different design requirements and has good universality and integrity.

Description

technical field [0001] The invention belongs to the technical field of design automation EDA in the integrated circuit design industry, and in particular relates to an ECO design method for semi-customized back-end design of integrated circuits. Background technique [0002] In the whole design process of integrated chips, designers usually need to continuously verify the design. For early design problems, designers can solve them by modifying the RTL code. However, in the later stage of design, such as nearing the final signoff (signoff), it needs to be implemented through an engineering change order (ECO, Engineering Change Order) technology. [0003] Therefore, the ECO design stage of chip design is an important part of the entire semi-custom back-end design process, but the current conventional ECO design method has defects, mainly due to poor design quality and too long iteration time. Therefore, it is necessary to propose an efficient ECO design method to improve the...
