摘要: 3D异构集成技术是未来电子行业的关键技术,促使电子系统朝着高性能、低延迟、小尺寸、轻质量、低功耗和低成本的方向发展。然而,随着信号传输速率和带宽的提高,异构集成系统各层级之间的相互干扰愈发显著,亟需多层级的协同仿真技术来捕获这种干扰,从而避免多次迭代造成的经济和时间成本增加。多层级协同建模和仿真技术可实现跨芯片-封装-系统领域的多层级协同开发以及跨电学、热学、机械学的多物理场协同分析,是实现3D异构集成的重要保障。介绍了异构集成协同仿真的基本概念,详述了协同仿真关键技术的发展和研究现状,总结了协同仿真的挑战和发展趋势。

Abstract: 3D heterogeneous integration is the key technology in the future electronic industry, which promotes the electronic systems to higher performance, lower signal delay, smaller size, lighter weight, lower power dissipation and lower cost. However, the mutual interferences between multi-levels in heterogeneous integration are becoming more and more serious. Multi-level co-simulation technology is needed to capture these interferences, thus enormous economic and time costs caused by multiple iterations can be avoided. Co-simulation and modeling technology can realize the co-analysis referring to die-package-system levels and electromagnetic, thermal and mechanical fields, and becoming a significant factor to guarantee the implementation of 3D heterogeneous integration. Basic concepts of co-simulation technology for 3D heterogeneous integration are introduced. And the developments and current situations of some key technologies such as modeling and parameter extraction, power distribution network (PDN) analysis and thermal-mechanical co-analysis are demonstrated in detail. The challenges and development trends in co-simulation technology are proposed.

Key words: 3Dheterogeneousintegration, multi-levelco-simulation, parameterextraction, signalintegrity, thermal-mechanicalco-analysis
