Physics-Guided Geometric Diffusion for Macro Placement Generation
Researchers introduce MacroDiff+, a physics-guided diffusion model that improves macro placement in VLSI chip design by combining graph neural networks with transformer architecture, achieving 6.1-6.2% wirelength reduction and superior scalability on large-scale designs compared to existing methods.
