本研究旨在开发有效的技术，用于建模和仿真的复杂系统上的芯片与数以百万计的晶体管，其中包含混合的模拟和数字电路，甚至混合技术的设备（微机电，光学，微流体等）。重点是探索行为建模，简单而准确的数学建模，电路的行为。一种基于符号网络分析的系统方法正在开发中，以产生从电路网表的行为模型。传统的符号网络分析应用于大型电路是阻碍了指数增长的产品条款的数量与电路的大小，一个问题被称为术语爆炸。本计画借由探讨决定性决策图（DDD）技术来解决术语问题。 为了生成高效的可模拟代码，该项目探索了编译技术来编译行为模型并选择合适复杂度的模型。一种新的并行和分布式仿真模式正在开发中，以利用最大的货币和延迟在混合模拟/数字和混合技术系统。

This research aims at developing efficient techniques for modeling and simulation of complex systems-on-a-chip with millions of transistors, which contain mixed analog and digital circuits, even mixed-technology devices (microelectromechnical, optical, microfluid, etc). The focus is to explore behavioral modeling, simple-yet-accurate mathematical modeling, of a circuit in terms of its behavior. A systematic method based on symbolic network analysis is being developed to generate behavioral models from a circuit netlist. Application of traditional symbolic network analysis to large circuits is hindered by the exponential growth of the number of product terms with the size of a circuit, a problem known as term explosion. This project addresses the term problem by exploring determinant decision diagram (DDD) technology. To generate efficient simulatable code, this project explores compilation techniques to compile behavioral models and to select models of right complexity. A new paradigm for parallel and distributed simulation is being developed to exploit the maximum currency and latency in mixed analog/digital and mixed-technology systems.
