New Simulation Methods for Accelerated Mixed-Signal Simulation

微电子技术的不断发展使得多个元件集成在一个芯片上成为可能。为了可靠地验证模拟电路和数字电路之间的相互作用，数模混合电路的验证需要特殊的方法。传统的模拟方法的性能已经不能满足当今混合信号系统级模拟日益增长的需求。该研究项目是基于一种方法的自动模型生成的加速混合信号模拟电路模型和相关的瞬态分析的仿真方法。研究表明，该方法具有良好的效果，大大提高了模拟/数字混合系统的仿真速度。该项目的基本目标之一是扩展新的仿真方法，使更多的输入信号类型。该项目的另一个目的是将新的仿真方法集成到传统的仿真环境中。因此，一个显着的加速验证集成混合信号系统可以实现。目前，只有小尺寸的混合信号电路在一个相对较低的抽象层次的模拟部分评估这种方法。由于传统的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.
