SwiftCTS: Fast Cross-Design Prediction and Pareto Optimization of Clock Tree Metrics via Few-Shot Calibration

In three linesSwiftCTS is a physics-informed surrogate framework for Clock Tree Synthesis. Trained in under 5 seconds on CPU with sub-millisecond inference, it uses K-shot multiplicative calibration to adapt predictions to unseen architectures without retraining. Evaluates 100,000 CTS configurations in 10 seconds with <0.5% errors on power and wirelength.
