This research has two complementary tracks; automatic generation of analog macromodels, and algorithms for analog multi-level simulation. The focus of the first track is on integrating macromodel optimization techniques with algorithms capable of generating macromodel topologies. Algorithms for generating analog macromodels from circuit level representations are being sought. Software embodying the algorithms is tailored to fit into an ordinary simulator's description language (e.g. SPICE3). A set of macromodels for common analog functions is being constructed. The critical problem for analog multi-level simulation is the inclusion of behavioral models in a simulation environment. Issues being addressed are: the use of "C" language, simulation synchronization, and circuit partitioning. A second problem is the inclusion of digital blocks in the multi-level simulation system. Here signal conversion from one domain to another is being explored. One approach being investigated is obtaining an extension of conventional Boolean algebra to real valued signals. This offers a simple way to include both analog and digital functions in a unified simulation environment.

这项研究有两个互补的轨道；自动生成模拟宏模型和模拟多级仿真算法。 第一个轨道的重点是将宏模型优化技术与能够生成宏模型拓扑的算法相集成。 人们正在寻求从电路级表示生成模拟宏模型的算法。 体现算法的软件经过定制，适合普通模拟器的描述语言（例如 SPICE3）。 正在构建一组常见模拟功能的宏模型。 模拟多级仿真的关键问题是将行为模型纳入仿真环境中。 正在解决的问题是：“C”语言的使用、仿真同步和电路分区。 第二个问题是在多级仿真系统中包含数字模块。 这里正在探索从一个域到另一个域的信号转换。 正在研究的一种方法是将传统布尔代数扩展到实值信号。 这提供了一种在统一仿真环境中包含模拟和数字功能的简单方法。
