一种模型化系统，包括一处理器，编程为用以分析一电路，以判断此电路对于射频信号的响应，作为设计、制造或测试此电路之依据。一转接板模型存储于非暂时性电脑可读存储媒体，并可供处理器所存取。转接板模型经电脑处理后输出代表硅通孔电极对射频信号之响应的数据。转接板模型包括复数个硅通孔电极模型，每个硅通孔电极模型都有其相对应的三端口网络，每个三端口网络其中一端口皆为浮动节点，每个三端口网络的上述浮动节点都连接在一起。

A computer implemented system comprises a processor programmed to analyze a circuit to determine a response of the circuit to an input radio frequency (RF) signal, for at least one of designing, manufacturing, and testing the circuit. An interposer model is tangibly embodied in a non-transitory machine readable storage medium to be accessed by the processor. The interposer model is processed by the computer to output data representing a representing a response of a though substrate via (TSV) to the radio frequency (RF) signal. The interposer model comprises a plurality of TSV models. Each TSV model has a respective three-port network. One of the ports of each three-port network is a floating node. The floating nodes of each of the three-port networks are connected to each other.
