集成电路设计已经发展到在单个芯片上或作为集成芯片组实现大型、复杂的模拟和数字功能的阶段。除了设计的混合信号特性外，模拟部分还包括连续时间和离散时间组件。因此，对于这些集成模块的分析，需要所有包含的仿真功能，不仅要解决混合模拟-数字电路的瞬态分析，还要解决频域分析。在本文中，我们提出的机制，多级和混合域模拟系统的模拟与混合模拟数字仿真。然后，我们描述了一个开放式的和可扩展的仿真框架，iMACSIM的形式实现。一个仿真背板是用来提供一个通用的事件处理和调度框架，将各种必要的算法，在不同的分析制度的各类电路的仿真。
Integrated circuit design has evolved to the stage where large, complex, analog and digital functionalities are implemented on a single chip or as an integrated chip set. Besides the mixed signal nature of the designs, the analog sections also include continuous-time and discrete-time components. Thus, for analysis of these integrated modules, all encompassing simulation capabilities are required that address, not only transient analysis of mixed analog-digital circuits, but frequency domain analysis as well. In this paper, we present mechanisms for multilevel and mixed-domain simulation of analog systems tied in with mixed analog-digital simulation. We then describe the implementation in the form of an open-ended and expandable simulation framework, iMACSIM. A simulation backplane is used to provide a general event-processing and scheduling framework that ties together the various algorithms necessary for simulation of various classes of circuits in different analysis regimes.
