Charge Trapping in Semiconductor Devices: From Device Level Modeling to Circuit Analysis
Charge capture and emission by defects (traps) close to the Dielectric-Semiconductor interface is a major source of noise in modern MOS devices. It also causes Bias Temperature Instability (BTI). A comprehensive physics-based modeling and simulation approach for BTI, RTN and low-frequency noise is reviewed, discussed and summarized. It allows for the derivation of analytical formulations for 1/f noise (frequency domain), RTN (time domain) and BTI (aging) using a single modeling framework, where model parameters are the same in frequency and time domain. Noise and BTI levels can vary by several orders of magnitude in deeply scaled devices, making variability a major concern in advanced MOS technologies. To ensure proper circuit design in this scenario, it is necessary to identify the fundamental mechanisms responsible for variability in noise and BTI. Time domain analysis is relevant for the analysis of digital and mixed-signal circuits. In digital circuits, the RTN chronological statistics, especially trap occupancy switching, have direct impacts on circuit performance and reliability, as degradations like jitter of signals happen when a trap switches state. The area scaling of RTN induced jitter (phase noise) and its variability is detailed and discussed, aiming to support circuit designers in transistor sizing towards a more reliable design. The applicability of the model here presented to the evaluation of logic gates and circuits is also discussed.

AI-Fused Prediction for Shift-Left Design Automation
The shift-left paradigm in Electronic Design Automation (EDA) seeks to move physically aware analysis into earlier design stages to improve quality, reduce iteration cost, and enable predictive digital twins. A key challenge is determining where early prediction is both accurate and impactful. This lecture presents AI-fused shift-left methodologies across critical stages of the EDA flow, from pre-RTL design to signoff, covering both digital and analog circuits. Examples include physically aware timing models integrated into logic synthesis, macro connectivity–aware optimization for improved routability, fast timing estimation tightly coupled with ECO processes for accelerated closure, and large language model–assisted analog circuit sizing. The lecture concludes with opportunities and challenges in accuracy, generalization, and toolchain integration, offering practical insights into how AI-enabled prediction can reshape modern design automation workflows.

From Papers to Physical Designs: Empowering LLM with Integrated Datasets
In the realm of circuit logic and machine learning models (LLMs), the availability and quality of datasets play a pivotal role in advancing research and development. This talk explores the critical importance of datasets in driving circuit LLM, focusing on a diverse array of datasets ranging from academic papers to commercial device specifications and physical designs. We delve into specific techniques, such as converting images to netlists, web crawling for extracting paper content, and computer vision for extracting data from figures. By leveraging these datasets and techniques, we enhance the accuracy, efficiency, and applicability of LLM in circuit design and analysis.
