Advanced methodologies and computer aided design tools for signal integrity analysis of high-speed circuits and systems

近年来，对高频和微型设计的强烈驱动一直处于微电子、通信和计算系统的仿真和验证方法新发展的前沿。设计要求变得非常严格，要求更高的工作速度，更尖锐的激励，更密集的布局和低功耗。因此，电路/EM/机械和热设计考虑之间的传统界限正在迅速消失。如果在设计阶段没有正确解决串扰和衰减等高速效应，可能会导致逻辑毛刺，使制造的数字电路无法工作，或者它们可能会使模拟信号失真，使其无法满足规格。为了解决上述困难，提出了一个新的研究计划，包括以下举措，以开发针对高速模块的新一代计算机辅助工具和方法：（a）开发快速/准确的信号和电源完整性分析工具，（B）开发以信号完整性为重点的并行电路模拟和优化工具;（c）混合域和多域计算机辅助设计工具和方法纪律分析。

During the recent years, the intense drive for high-frequency and miniature designs has been at the forefront of new developments in simulation and verification methodologies focused on microelectronics, communication and computing systems. The design requirements are becoming very stringent, demanding higher operating speeds, sharper excitations, denser layouts and low power consumption. Consequently, traditional boundaries between the circuit/EM/mechanical and thermal design considerations are rapidly vanishing. High-speed effects such as crosstalk and attenuation, if not addressed properly during the design stage, can cause logic glitches which render a fabricated digital circuit inoperable, or they can distort an analog signal such that it fails to meet specifications. To address the above difficulties, a new research program with following initiatives is proposed to develop new-generation computer-aided tools and methodologies targeting high-speed modules: (a) Development of fast/accurate signal and power integrity analysis tools, (b) Development of parallel circuit simulation and optimization tools with emphasis on signal integrity and (c) Computer-aided design tools and methodologies for mixed-domain and multi-disciplinary analysis.
