New Simulation Methods for Accelerated Mixed-Signal Simulation

它在微电子领域的不断发展使单个芯片上的多组件集成度越来越高。为了可靠地验证模拟电路与数字电路之间的相互作用，混合信号电路的验证需要特殊的方法。目前，传统仿真方法的性能已不能满足日益增长的混合信号系统级仿真的要求。本研究项目是基于加速模拟电路模型混合信号仿真的自动模型生成方法和相关的瞬态分析仿真方法。研究取得了良好的效果，大大加快了模拟/数字混合系统仿真的速度。到目前为止，目前的方法仅限于分段恒定输入刺激。这个项目的一个基本目标是扩展新的仿真方法，使额外的输入信号类型。该项目的另一个目标是将新的仿真方法集成到传统的仿真环境中。因此，可以实现集成混合信号系统验证的显着加速。目前，仅对模拟部分抽象程度较低的小型混合信号电路进行了评估。由于传统仿真环境的支持和集成，可以实现系统验证的加速。在此之后，应该分析模拟器属性的性能。这些检查应在其他模拟环境内外进行。

Its continuous development in microelectronics enables an increasing integration of multi components on a single chip. In order to reliably verify the interaction between analog and digital circuit, the verification of mixed-signal circuits requires special methods. Today the performance of traditional simulation methods are insufficient to meet the increasing demands of the present mixed-signal system-level simulation. This research project is based on an approach for the automated model generation for accelerated mixed-signal simulation of analog circuit models and the associated simulation methodology for a transient analysis. Studies have shown good results, which make a significant acceleration in the simulation of mixed analog/digital-systems.Up to now, the current approach is limited to piecewise-constant input stimuli. One of the fundamental goals of this project is an extension of the novel simulation methodology that enables additional input signal types. A further aim of the project is to integrate the novel simulation methodology into conventional simulation environments. Thus, a significant acceleration in verification of integrated mixed-signal-systems can be achieved.At present, merely small-sized mixed-signal circuits at a relatively low level of abstraction of the analog part are evaluated for this approach. Due to the support and integration of conventional simulation environments an acceleration of a system-verification can be reached. Subsequent to this, the performance of the simulator properties should be analyzed. These examinations should be performed within and outside of other simulationenvironments.
