Physics-Guided Geometric Diffusion for Macro Placement Generation

In three linesMacroDiff+ is a physics-guided geometric diffusion framework for macro placement optimization in VLSI physical design. Using a dual-domain architecture (heterogeneous GNNs + Transformer) and physics-guided gradient-based sampling, it achieves 6.1-6.2% wirelength reduction on ISPD2005 benchmarks with superior stability on large-scale designs.
