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.

近年来，高频和微型设计的强烈动力一直位于仿真和验证方法中的新发展的最前沿，这些方法集中在微电子，通信和计算系统上。设计要求变得非常严格，要求更高的运行速度，更清晰的激发，密集的布局和低功耗。因此，电路/EM/机械和热设计方面之间的传统边界迅速消失。高速效应，例如串扰和衰减，即使在设计阶段无法正确解决，可能会导致逻辑故障，从而使制造的数字电路无法操作，或者它们可能会扭曲模拟信号，使其无法满足规格。为了解决上述困难，提出了一项具有以下计划的新研究计划，以开发针对高速模块的新生成计算机辅助工具和方法：（a）开发快速/准确的信号和功率完整性分析工具，（b）在信号完整性和（C）计算机设计工具和方法论中，并将其重点放在平行电路仿真和优化工具上，以进行计算机设计工具和方法。
