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.

该报告首先描述了一个基于波形放松的耦合输电线路模拟器Desire3T+。首先，审查了广义的特性MEHTOD（GMC），该特征（GMC）用等效的脱节网络代替有损耗的传输线。接下来，提出了广义线延迟窗口（GLDW）分区技术，该技术加速了传输线电路的瞬态分析。此外，在Desire3T+中实现了GMC模型和GLDW技术，并估算了性能。此外，一种用于行为模型的模拟/数字混合电路的多级模拟器。已经通过详细的电路模拟器（例如香料）分析了模拟电路。由于详细的电路仿真非常密集，因此模拟大型和COMPLES电路的必要性促使使用行为模型开发了多层模拟。我们的模拟器是基于拆分开发的，并可以通过考虑子电路之间的耦合效应来分析体内的所有子电路。这种方法有助于同时设计模拟电路和模拟/数字混合电路。
