ADS PCB仿真

我用ADS 仿了一个功分器，在ADS原理图导入到PCB后，隔离电阻没作用了，Momentum RF仿真出来的S11 S21 S31 还行 但S22 S33 S23 都差得离谱，初步分析是隔离电阻没有参与计算，请问高手器件怎么和PCB同时在Momentum RF里面仿真?
第二个问题
我将Momentum RF仿真后的数据，再导入到原理图进行仿真，为什么没有看到ref的参考点，只有几个端口?

谢谢！

要用原理图版图联合仿真吧。先把PCB生成原件。再回到原理图取出PCB原件再加电阻

自己顶下

这个错误又怎么解决[/COLOR]

期待

联合仿真报错，请教下怎么解决,谢谢！
