This research explores full-wave simulation techniques to facilitate the application of such tools to high-performance VLSI system design. It also investigates new design methodologies for system-level power delivery structures and on-chip interconnects for next-generation VLSI design. Computational work builds on an advanced full-wave simulation method: finite-difference time-domain (FDTD). The research focuses on 1) full-wave simulation algorithms to enable VLSI system-level full-wave simulation, 2) effective use of the full-wave simulation engine to investigate power fluctuation and signal integrity issues for VLSI interconnects, 3) exploration of time-of-flight effects, frequency-dependent behavior, and electrical and magnetic cross-coupling at the chip level, 4) investigation of power dip/ground bounce for the purpose of identifying design blocks that are vulnerable to power fluctuations, 5) evaluation of the impact of decoupling capacitors on power delivery.

本研究探索全波仿真技术，以促进此类工具在高性能 VLSI 系统设计中的应用。它还研究了用于下一代 VLSI 设计的系统级功率传输结构和片上互连的新设计方法。计算工作建立在先进的全波模拟方法之上：时域有限差分 (FDTD)。研究重点是 1) 全波仿真算法，以实现 VLSI 系统级全波仿真，2) 有效使用全波仿真引擎来研究 VLSI 互连的功率波动和信号完整性问题，3) 探索飞行时间效应、频率相关行为以及芯片级的电气和磁性交叉耦合，4) 研究功率骤降/接地弹跳，以实现 识别易受功率波动影响的设计模块，5) 评估去耦电容器对功率传输的影响。
