NeuroSteiner: A Graph Transformer for Wirelength Estimation
NeuroSteiner: A Graph Transformer for Wirelength Estimation
A core objective of physical design is to minimize wirelength (WL) when placing chip components on a canvas. Computing the minimal WL of a placement requires finding rectilinear Steiner minimum trees (RSMTs), an NP-hard problem. We propose NeuroSteiner, a neural model that distills GeoSteiner, an optimal RSMT solver, to navigate …
