采用 ABCD矩阵法对传输高速信号的背板上具有频变参数的互连线建立等效时域网络模型 ,并给出接插件等效传输线模型和端接的 I/O缓冲器 IBIS瞬态行为模型 ,利用这些模型对实际电路进行仿真 ,其结果与 Ansoft公司的 PNC软件仿真结果相吻合 ,仿真效率有明显提高。
An equivalent time-domain network model of interconnect with frequency-varying parameters on the backplane of high-speed signal is established by ABCD matrix method. The equivalent transmission line model of connector and IBIS transient behavior of terminated I / O buffer are given. The simulation results show that the simulation results are in good agreement with the simulation results of Ansoft PNC software and the simulation efficiency is obviously improved.
