摘要
高速多芯片组件(MCM)广泛用于高复杂度的系统中,而其中的同步开关噪声(Simultaneous Switching Noise)是影响系统功能的重要因素.本文采用二维电磁模型模拟MCM电源、接地板同步开关噪声;文中提出一种新的时域电磁问题的数值方法—特征法,并用于求解上述问题,所得结果与FD-TD计算的结果和文献报道一致.
High speed Multi-Chip Module (MCM) has been widely adopted in the complex system, where simultaneous switching noise is one of the key factors affecting the system function. In this paper, two dimensional electromagnetic model is used to simulate power/ground plane simultaneous switching noise in MCM. A novel numerical method for the time-domain electromagnetic problems, named method of characteristics, is presented and used to solve the above problem. The results obtained are in accordance with that by the method of FD-TD and that reported by literature.
