張耀文特聘教授 Yao-Wen Chang Distinguished Professor 講題：Physical Design for Heterogeneous Integration: Challenges, Solutions, and Opportunities 簡報下載 國立台灣大學電機工程學系 Department of Electrical Engineering, National Taiwan University ABSTRACT： Achieving power, performance, and area (PPA) targets in modern semiconductor design increasingly relies on More-than-Moore heterogeneous integration, as the economic benefits of More-Moore on-chip scaling continue to diminish. The escalating costs of advanced technologies, driven by EUV lithography, mask sets, fabrication, design, and EDA tools, further reinforce this shift. Heterogeneous integration combines separately manufactured components into higher-level assemblies, such as CoWoS or multiple packages on a PCB, to deliver enhanced functionality and improved operating characteristics. Unlike conventional on-chip designs with relatively uniform components and interconnects, the physical design of heterogeneous systems must accommodate irregular component and board geometries, varying metal line widths, and diverse spacing rules among components, wires, and pads. Moreover, it must address cross-domain effects spanning system-level, physical, electrical, mechanical, thermal, and optical considerations, challenges not well captured by traditional chip design flows. In this talk, we introduce mainstream heterogeneous integration technologies and design options, discuss their layout modeling and associated physical design challenges, review key published solutions, and highlight promising directions for future research in heterogeneous physical design. Keywords: Power, Performance, and Area (PPA); More-Moore; More-than-Moore; Heterogeneous Integration; Physical Design; Layout; Electrical, Mechanical, Thermal, and Optical Effects; EDA Research Interests：

講題：From equations to emulators: Recent advances in accelerating fluid dynamics prediction with data-driven methods 國立臺灣大學應用力學研究所 ABSTRACT： Recent advances in data-driven techniques have driven a surge in the development of data-driven methods for predicting fluid dynamics. Unlike traditional computational fluid dynamics (CFD), which numerically solves partial differential equations governing flow behavior, data-driven approaches aim to accelerate flow prediction using modern statistical and AI techniques, resulting in surrogate or emulation models. These surrogate models generally fall into three categories: data-fitting, multi-fidelity, and projection-based methods. While data-fitting methods focus on point-to-point predictions, this talk will highlight our recent work in the second and third categories. In the multi-fidelity category, I will present two models: a multiscale modeling framework for granular flows using active learning, and a tensor-based neural network for turbulent flow modeling. The former leverages Gaussian Processes to connect microscale and macroscale simulations, while the latter improves the accuracy of low-fidelity turbulence models using neural networks. In the projection-based category, we introduce a flow emulator for predicting the spatiotemporal evolution of turbulent wakes behind blunt bodies. This model combines spectral proper orthogonal decomposition with kriging techniques. Following this overview of our recent progress, I will discuss key challenges and future directions in the development of data-driven flow prediction models. Research Interests：

講題：Computational plasticity for bio-inspired structural materials 國立臺灣大學土木工程學系 ABSTRACT： Bio-inspired structural (BIS) materials are synthetic composites designed by imitating the microstructural features of biological materials, offering attractive properties and significantly better performance than their constituents. Among BIS materials, the cellular material is one kind of man-made material with the cellular microstructure. It is inspired by many natural materials such as wood, cork, and bone, which is renowned for its stiff yet lightweight characteristics. To explore the mechanical behavior of the cellular materials, many investigations have been conducted, and these strengthen the performance of the cellular material. In this study, we investigate the plastic behavior of 2D cellular materials and especially focus on the yield surface evolution of 2D cellular materials. The finite element simulation of cellular materials with different microstructures is adopted, and the representation block approach is selected to study the initial and subsequent yield surfaces of cellular materials. To establish the proper finite element model of cellular materials, the size effect analysis and the boundary effect analysis are conducted, and the yield point determination is proposed. For the detection of initial and subsequent yield surfaces, the probing path and the preloading path are designed. In addition, in order to study their plastic behavior accurately, we propose an elastoplastic constitutive model that incorporates anisotropy, tension-compression asymmetry in yielding, and nonlinear anisotropic hardening, along with its associated plastic integration scheme. The integration, called return-free integration, is based on the internal symmetries of the model, which relies on Lie algebra and Lie group theory, and efficiently solves the nonlinear coupled ODEs for stress while automatically satisfying the yield condition. The proposed model and integration method have been successfully implemented in the user material subroutine (UMAT) of the finite element software ABAQUS. Using this finite element framework, we conduct the simulation to detect the yield point of cellular materials under different loadings and then to investigate their yield surface evolution. Furthermore, the same methodology has been applied to the investigation of the yield surface evolution of cellular composites. The influence of the microstructures on the yield surface evolution of both cellular materials and cellular composites is carefully explored in this study. Keywords: Plasticity, Return-free integration, Bio-inspired structural materials, Cellular composites, Yield surface evolution. Research Interests：

吳清森教授Ching-Sen Wu Professor 講題：Scale-resolved Simulations of Gravity Currents Transport Processes: Insights from Turbulent Eddies to Engineering Solutions 國立宜蘭大學土木工程學系 ABSTRACT： The prediction of suspended sediment motion in fluvial systems serves as a key technology for understanding the gradual sediment transport and deposition processes. Gravity currents, as flow phenomena driven by density differences, constitute the core turbulent transport mechanisms controlling suspended sediment dynamics in riverine environments. In this talk, we employ scale-resolved simulations based on high-resolution large eddy simulation (LES) that bridge fundamental turbulent eddy dynamics analysis with practical engineering applications. Unlike commonly used depth-resolving models in engineering applications, our approach captures three-dimensional turbulent characteristics that these models cannot easily resolve. The research addresses specific engineering challenges in reservoir desilting during non-typhoon periods. During these periods, gravity currents not discharged through desilting conduits become susceptible to energy dissipation before probabilistic settling due to topographical constraints. Through high-fidelity numerical modeling, this study analyzes the interaction mechanisms between gravity current turbulent structures and underwater obstructions, quantifying their effects on momentum flux characteristics and sediment-carrying capacity. Based on both qualitative and quantitative analysis, we develop underwater structure configurations that more effectively enhance reservoir desilting efficiency. Overall, this research captures multi-scale turbulent characteristics, from high-energy large-scale eddies that dominate momentum transport to small-scale dissipative motions, controlling suspended sediment transport processes. By analyzing the small-scale evolved vortical structures in simulations, we propose an alternative engineering solution, providing practical strategies for water resource management in reservoir. Keywords: Gravity currents, Large eddy simulations, Turbulent transport process Research Interests：
