Late Breaking Results: Unified PCB Routing Considering Pair-Spacing and Width-Range Constraints
DescriptionModern printed circuit boards (PCBs), especially high-power PCB designs, impose diverse design requirements that demand automated routing. Although grid-based data structures can enforce design rules, they often incur excessive via usage and long runtimes due to insufficient global planning. This paper presents a constraint-driven routing framework that systematically addresses these challenges. Our framework features three key techniques: (1) a crossing-aware global routing method that models and enforces pair-spacing and width-range constraints, (2) a spatial-order preservation strategy that expands the solution space by avoiding premature pruning of alternative routing states, and (3) a piecewise net-sizing technique that allocates net widths according to routing resources while maintaining rule compliance. Experimental results demonstrate the effectiveness of our proposed framework while satisfying all design rules.
