Efficient Automation Strategy for Package Substrate Routing
DescriptionThe existing automatic routing tools often produce design rule violations and fail to meet the required routing completion rate when dealing with the complex electrical connection and constraints. In this work, an algorithm of determining auxiliary point is introduced to guide the auto-routing tool to generate a preliminary layout for FCBGA substrate, and then the preliminary layout is optimized by Residual Neural Network and Decision Transformer model. The auxiliary point corresponding to die pad is disposed in proximity to the die edge and its coordinate is determined by the corresponding die pad coordinate, signal type and design rules, such as the minimum trace width and spacing. Experimental results demonstrate the proposed method effectively achieves high routing completion rate and enhances layout defects including detour and dense routing.
