Researchers have developed CLDRoute, a novel framework for estimating routability in physical design by treating it as a conditional generation problem. Unlike previous deterministic methods, CLDRoute models congestion and DRC violations as structured fields, enabling sample-based inference that provides both a mean prediction and an estimate of spatial uncertainty. This approach offers a more practical view of routability during the placement stage, yielding improved metrics on the CircuitNet 2.0 dataset. AI
