This report describes, first, a waveform relaxation-based coupled lossy transmission lines circuit simulator DESIRE3T+. First, the generalized mehtod of characteristics (GMC) is reviewed, which replaces lossy transmission lines with equivalent disjoint networks. Next, the generalized line delay window (GLDW) partitioning technique is proposed, which accelerates the transient analysis of transmission lines circuits. Furthermore, GMC model and GLDW technique are implemented in DESIRE3T+, and the performance is estimated.Moreover, a multi-level simulator for analog/digital mixed circuits with behavioral models is prescnted. Analog circuits have been analyzed by the detailed circuit simulator such as Spice. Since the detailed circuit simulation is very compute-intensive, the necessity of simulating large and comples circuits has prompted the development of multi-level simulation with behavioral models. Our simulator has been developed based on SPLIT and enables to analyze all of the subcircuits in a body with the consideration of the coupling effect between subcircuits. This methodology aids the concurrent design of analog circuits and analog/digital mixed circuits.

本报告首先介绍了一个基于波形松弛的耦合有损传输线电路模拟器<$RE3T+。本文首先回顾了用等效不相交网络代替有耗传输线的广义特征线法。其次，提出了广义线延迟窗（GLDW）划分技术，加速了传输线电路的瞬态分析。在此基础上，本文还利用GMC模型和GLDW技术在ARMRE 3 T+上实现，并对其性能进行了评估，提出了一种基于行为模型的模拟/数字混合电路多电平仿真器。模拟电路已经被详细的电路仿真器如Spice分析。由于详细的电路仿真是非常计算密集型的，仿真大型和复杂的电路的必要性，促使了多层次仿真与行为模型的发展。我们的模拟器已经开发的基础上分裂，并能够分析所有的子电路在一个机构与子电路之间的耦合效应的考虑。该方法有助于模拟电路和模拟/数字混合电路的并行设计。
