How to simulate spiral inductor by HFSS ?
I don't know how to set boundary condition and excitation.
So I am not sure the simulation result correct or not.
Anyone have experience to share with me.
At first you have to create the 3D model of your spiral, afterwords place exitation as lumped ports and radiation boundary cond. at air box. Use driven terminal solution to calculate S-parameters.
Some tricks should be used for the accurate results of spiral inductor in HFSS simulation. It is better to use Ansoft Designer/ IE3D/Momentum, etc, for 2.5D structure.
