EDISCO: Equivariant DIScrete Diffusion for Euclidean Combinatorial Optimization
Ruogu Chen, Jie Han
Euclidean combinatorial optimization problems (ECOPs), such as the Traveling Salesman Problem (TSP) and Capacitated Vehicle Routing Problem (CVRP), possess inherent symmetries unde…
PPAPlace: Differentiable Cross-Stage Objectives for Chip Placement Optimization
Ruogu Chen, Jie Han
Macro placement significantly affects a chip's post-route performance, power, and area (PPA). Most placement methods optimize half-perimeter wirelength (HPWL) as the primary object…
CoEvoP&R: Co-Evolving Placement Objectives with Routing Feedback via Large Language Models
Ruogu Chen, Weihua Xiao, Ramesh Karri +1
Analytical placers rely on differentiable objective functions to guide placement, typically combining intermediate surrogate metrics such as half-perimeter wirelength (HPWL) and ce…
An Architectural Error Metric for CNN-Oriented Approximate Multipliers
Ao Liu, Jie Han, Qin Wang +2
As a potential alternative for implementing the large number of multiplications in convolutional neural networks (CNNs), approximate multipliers (AMs) promise both high hardware ef…
