本文研究的是MOS（金属氧化物半导体）的模拟 集成模拟和数字元件的电路。 他 提出了一种大规模网络划分算法， 电路分成许多小规模的子电路， 相互隔离。 该算法创建了一个 电路的单向信号路径图。 一旦这样 完成后，将全局电路仿真解耦为单个 根据图中的深度级别进行子电路分析。 模拟的一部分使用事件驱动松弛，这是一个 事件驱动模拟和波形松弛的组合。 他正在研究一种特殊用途的模拟仿真器， 模拟行为 另一个问题是算法，它使用片段- 明智的线性时序分析， 估计数字支路响应。

This rewsearch is on simulating MOS (metal oxide semiconductor) circuits which integrate analog and digital components. He proposes an algorithm which partitions a network of large-scale circuits into numerous small-scale subcircuits which are resistively isolated from each other. The algorithm creates a unidirectional signal path graph for the circuit. Once this is done, the global circuit simulation is decoupled into individual subcircuit analyses by following the depth levels in the graph. Part of the simulation uses event-driven relaxation, which is a combination of event-driven simulation and wave-form relaxation. He is investigating a special purpose analog simulator to analyze analog behavior. Another problem is algorithms which use piece- wise linear timing analysis to efficiently and accurately estimate digital subcircuit response.
