Secondly , a network based on multi - terminal components modeling methodology was applied to model mems at system - level by the analogy and mixed - signal modeling tool of vhdl - ams , for the system - level model of mems is a mixed signal model , which has attributes of multi - energy domains coupling , multi - signals mixed and interacting between discrete - event subsystems and continuous - time subsystems . with this method , the whole system can be divided into some subsystems defined as multi - terminal components ; the behavior of the subsystems depends only on their terminal signals ; the information exchange between subsystems was done by the signals at their terminals . the continuous - time systems or discrete - event systems can be modeled and simulated with this method , which satisfied the requirements of nonlinear systems and large signals analysis 同时,针对mems的系统级模型是一个混合信号模型,具有多能量域耦合、多信号混合、离散事件子系统与连续时间子系统交互的特点,使用vhdl - ams作为混合信号模型建模的工具,采用多端口组件网络建模方法建立了mems系统级模型,把微型机电系统分解为多个子系统或组件,各子系统被定义为多端口组件,子系统的内部行为通过其端口行为来描述,子系统间的能量与信号的交换通过组件的端口映射来实现,从而实现了对连续时间系统和离散事件系统的建模与仿真,满足了非线性系统以及大信号分析要求。
