Copper-deficiency automatic supplementing method with no need of repeatedly avoiding copper

Abstract

The invention discloses a copper-deficiency automatic supplementing method with no need of repeatedly avoiding copper, and relates to the technical field of EDA. On the basis of cadence software, deficient copper of a Shape is automatically supplemented through a Skill program interface of Allegro software; the method comprises the main steps that 1, attribute setting is performed on deficient holes of the Shape; 2, each deficient hole is detected step by step, and whether a via exists in each deficient hole or not is determined; 3, the Shape with the deficient holes needing to be supplemented is determined and selected, and all the deficient holes with no via are supplemented. The method is beneficial to rapidly designing a PCB, redundant workloads brought by manual multistep operations in design are effectively avoided, and the designing speed of the PCB is increased.

Description

technical field

[0001] The invention relates to the technical field of EDA, in particular to a method for automatically filling copper deficiency without repeating copper avoidance. Background technique

[0002] With the development of society, people's requirements for electronic products are getting higher and higher. In order to cater to and satisfy the public's psychology, the electronic information industry is also conducting continuous research and practice, developing new electronic products, and promoting the development of the information age. . The upgrading of electronic products promotes the rapid development of the electronic industry. As the cornerstone of development, PCB board design requires continuous improvement and innovation. Cadence software has very rich and powerful functions, and it has good operability. It can edit its database, so as to realize some functions that the program does not provide, and improve the efficiency of layout work. However, i...
