SUMMARY:Late Breaking Results: Training-Free CCS Library Generation via Vo
 ltage Domain Transformation and PCHIP Interpolation
DESCRIPTION:Meng-Hsuan Ho (National Yang Ming Chiao Tung University); Hung
 -Ming Chen (Institute of Electronics, National Yang Ming Chiao Tung Univer
 sity); and Hsuan-Ming Huang and Jiun-Cheng Tsai (Mediatek)\n\nAccurate tim
 ing-library generation across PVT conditions has become increasingly expen
 sive in advanced technology nodes. This paper introduces a robust, trainin
 g-free method for inferring CCS library entries at target PVT corners by i
 nterpolating voltage waveforms, rather than currents, using shape-preservi
 ng interpolation. By working in the voltage domain, the approach avoids th
 e instability and outliers often seen in ML-based current prediction and p
 roduces physically consistent results. Experiments on the ASAP7 and CAD Co
 ntest datasets show that our method outperforms leading ML regressors, red
 ucing CCS error by more than 100×. The result is faster, safer digital sig
 noff with minimal additional characterization overhead.\n\nTrack: Student\
