SUMMARY:Late Breaking Results: Advanced PCB Placement with Irregular Compo
 nents for Efficient Collision Detection and Routability Optimization
DESCRIPTION:Chien-Hao Tsou, Zhu-Xun Lee, and Yao-Wen Chang (National Taiwa
 n University)\n\nThis paper introduces an automated placement framework to
  optimize component positioning on modern printed circuit boards (PCBs), a
 ddressing challenges posed by heterogeneous components, irregular geometri
 es, and complex design rules. The framework employs three key techniques t
 o enhance placement quality and efficiency: (1) a global placement approac
 h integrating collision detection via the Separating Axis Theorem to handl
 e exact component contours and board shapes, (2) a multi-stage force-direc
 ted method that dynamically adjusts attractive and repulsive forces to mee
 t clearance and routability constraints, and (3) a scanline-based legaliza
 tion technique to resolve overlaps and enforce spacing requirements. Our m
 ethodology effectively adapts to diverse design limitations and accelerate
 s the process while preserving placement quality. Experimental results dem
 onstrate that our placer significantly improves routability over state-of-
 the-art solutions, demonstrating robust performance on industrial PCB desi
 gns with complex and irregular constraints.\n\n
