AI Technical Summary
Technical Problem
Traditional printed circuit board (PCB) circuit design is time-consuming and labor-intensive, prone to errors, and makes it difficult to guarantee layout quality and stability, affecting signal integrity, thermal management, and EMI, leading to performance and reliability issues.
Method used
A routing method is adopted, which divides the area to be optimized into several nested ring areas and quadrants, calculates the routing density, selects the quadrants to be corrected, and connects the global shortest path to lay out the route, thereby achieving automated optimization.
Benefits of technology
It enables automated optimization of printed circuit board design, saving labor costs, improving design quality, and ensuring performance and reliability.

Abstract
This application relates to a routing method applied to printed circuit board (PCB) design. First, the area to be optimized for routing on the PCB is divided into several annular regions. These annular regions are then further divided into quadrants. Next, all quadrants within the annular regions that require correction are selected. A global shortest path is obtained by connecting all the quadrants in the global shortest path. Finally, the routing is performed sequentially from the inside out on the quadrants included in the global shortest path corresponding to each annular region until the routing of the area to be optimized on the PCB is complete. This routing method enables automated analysis and processing of the routing area to be optimized, thereby achieving routing area optimization. This not only significantly reduces manpower input in the PCB design process and saves manufacturing costs, but also effectively improves the circuit design quality of the PCB, thus ensuring the performance and reliability of the PCB.
