CoEvoP&R: Co-Evolving Placement Objectives with Routing Feedback via Large Language Models

Ruogu Chen, Weihua Xiao, Ramesh Karri, Jie Han

Analytical placers rely on differentiable objective functions to guide placement, typically combining intermediate surrogate metrics such as half-perimeter wirelength (HPWL) and cell-density penalties. However, these placement-stage surrogates remain misaligned with downstream ro…Read more
