Machine Learning Applications in Electronic Design Automation

Machine learning is reshaping electronic design automation by offering data‐driven models that accelerate and enhance every phase of integrated circuit development. At design time, regression and classification algorithms predict performance metrics such as delay, power consumption and routing congestion, reducing reliance on iterative tool runs. During physical design, deep neural networks and graph‐based architectures capture connectivity and spatial features to forecast detailed routing violations, timing slack and IR-drop hotspots. Reinforcement learning agents automate stimulus generation for functional verification, while surrogate models speed up static timing analysis and engineering change order (ECO) closure. Collectively, these techniques deliver faster time-to-market, lower development costs and improved reliability, addressing the exponential complexity of modern semiconductor nodes and three-dimensional integration.

MLCAD: A comprehensive survey has categorised machine learning usage in CAD flows, distinguishing design-time optimisation (exploring architecture and floorplanning) from run-time parameter tuning (voltage-frequency trade-offs). It highlights well-explored domains such as regression for timing prediction and underexplored areas like generative models for layout synthesis, outlining open challenges in data scarcity and model interpretability.

Machine-Learning-Based Multi-Corner Timing Prediction for Faster Timing Closure: This work introduces a strategy to select dominant corners for static timing analysis, using regression models to predict non-dominant corner results from a small subset of runs. On standard benchmarks and industrial designs, it achieves over 98 % prediction accuracy while halving runtime, demonstrating that targeted ML surrogates can streamline multi-corner timing closure without compromising sign-off quality.

TSTL-GNN: Graph-Based Two-Stage Transfer Learning for Timing ECO Analysis: Addressing the costly process of timing engineering change orders, this approach employs graph neural networks with a two-stage transfer learning pipeline. The first stage predicts transition times; the second predicts path delays, reusing features learned earlier. Experiments on open-source and industrial designs report R² scores above 0.995 and reduce path-delay prediction time by up to 80×, offering a generalisable framework for rapid ECO iteration.
