AI Technical Summary

Technical Problem

Existing technologies fail to effectively classify obstacles, leading to push failures or violations of design rules during printed circuit board routing, and lack effective recovery mechanisms, thus reducing routing success rates.

Method used

By classifying obstacles by their shovelability, shovelable objects are distinguished from non-shovelable objects, geometric occupancy areas are constructed, and safety clearances are monitored in real time during the offset process. Path backtracking and replanning are used to ensure that the wiring complies with the rules.

Benefits of technology

It improves the safety and robustness of the cabling process, ensures that the cabling results meet electrical connectivity and design rules, and increases the cabling completion rate.

Abstract

The invention relates to the technical field of electronic design automation, and provides a printed circuit board wiring method and device, equipment, a medium and a program, and the method comprises the steps: classifying an obstacle as a pushable object or a non-pushable object; based on the relative position relationship between the initial path and the pushing object, constructing a geometric occupied area of the pushing object, and performing path offset on the pushing object according to the geometric occupied area; in the deviation process, if the distance between any deviated object capable of being pushed and any deviated object not capable of being pushed is smaller than a preset safety distance, further deviation is stopped, and the deviated object capable of being pushed is reversely returned along the deviation track of the object until the distance between the object capable of being pushed and the object not capable of being pushed is larger than or equal to the safety distance; and re-planning a final path of the signal line according to the position of each pushable object after returning, and outputting a wiring result according with a wiring rule. The method is used for optimizing and completing signal path optimization and distribution in an environment with obstacles.
