I have started the design of a high speed digital design multi-gbps interfaces. I would like to use Altium designer for PCB analysis (signal integrity). But I am wondering if altium uses the IDEAL model of a capacitor for simulation. The impedance/frequency response of typical capacitors is something like the below figure
So the impedance/frequency characteristic is quite different than an IDEAL model (There is a parallel issue with inductors and partly resistors too). My Questions are:
1-Does Altium use ideal models for signal integrity analysis?
2-If the answer to 1 is Yes then why? To what degree results are valid?
3-What is the policy of HyperLynx in this situation?
