Hybrid ML for Lightweight Pre-Route Delay Estimation in Open-Source IC Design proposes a lightweight machine learning approach that combines a decision tree with linear regression to improve pre-routing delay estimations for the open-source RTL-to-GDSII tool OpenLane. The model reduces error by 80% compared to OpenLane’s estimates and improves performance by 71% even without using OpenLane-specific parameters. It is over 300 times smaller, twice as fast, and offers higher explainability than traditional delay propagation techniques and more complex ML models.

LevelSyn introduces a physical-aware logic synthesis framework that uses a level-asynchronous Graph Neural Network to predict accurate gate coordinates by learning the structural and directional semantics of And-Inverter Graphs. It incorporates a level-aligned subgraph partitioning strategy to handle large designs and integrates these spatial insights into a new synthesis engine within the Berkeley ABC framework. Experiments on the EPFL benchmark suite show significant improvements, with an average power reduction of 6.89%, a timing delay improvement of 27.48%, and a 99.59% reduction in design rule check violations.

The paper introduces STEP‑KD, a Sequential Timing Evaluation via Progressive Knowledge Distillation framework for predicting post‑routing timing from early‑stage design data. By training teacher models at post‑routing, post‑placement, and post‑floorplan stages and sequentially distilling their knowledge to a post‑synthesis student model through representation alignment, STEP‑KD bridges the abstraction gap that hampers existing machine learning approaches. Experiments on diverse circuits show that STEP‑KD reduces the weighted mean absolute percentage error of Total Negative Slack prediction to 19.78% versus 74.84% for the industry‑standard Static Timing Analysis tool.
LevelSyn is a physical-aware logic synthesis framework that uses a level-asynchronous Graph Neural Network to predict high-fidelity gate coordinates by learning the structural and directional semantics of And-Inverter Graphs. It incorporates a level-aligned subgraph partitioning strategy to manage industrial-scale designs and integrates these spatial insights into a new synthesis engine within the Berkeley ABC framework. Experiments on the EPFL benchmark suite show LevelSyn outperforms state-of-the-art methods, achieving an average power reduction of 6.89%, a timing delay improvement of 27.48%, and a 99.59% reduction in design rule check violations.

ReDIL-GNN is a framework for resynthesis domain‑incremental learning in circuit graph neural networks. It adapts a fixed prediction or representation head as new synthesis styles appear and evaluates retention across all previously seen domains. The method introduces the Resynthesis Adaptability Index (RAI), a pre‑adaptation score that combines adaptation need, source‑equivalence recoverability, structural coverage, and update compatibility to decide whether to adapt, reuse, or defer updates.
