Researchers have developed HGRP, a novel heterogeneous graph neural network designed to improve the prediction of circuit routability. This model effectively captures multi-level circuit semantics by representing cells, nets, and routing grids as distinct node types, enabling better information interaction and feature fusion. Experiments on the CircuitNet dataset demonstrated that HGRP significantly enhances congestion prediction performance, achieving an 18.69% relative improvement in F1-score over existing state-of-the-art methods. The source code for HGRP is publicly available. AI
