Hi guys,

Hope you're doing fine. I'm now working with the design of a wideband amplifier. It's operating frequency range is 3-7GHz. I'm using assura rcx for parasitic extraction. Unfortunately, I don't have the provision for extracting parasitic inductance with that tool. The amplifier has an input matching network (utilizing chebyshev network) which includes long metal traces. Since I'm working in that frequency range, I think, I need to consider the effect of parasitic inductance along with parasitic resistance and capacitance.

Can anyone suggest me what to do now?

You can simulate the long metal traces in EM software and include them in your cadence simulation.

Probably Assura RCLx definition does not cover Inductance information..
As psmon said, Assura RCLx extraction can not see precisely the inductances.You should simulate these with EM simulator. At that frequency don't trust too much Assura..

In my lab, some people use HFSS V9 for antenna simulation. I want to import gds2 data in hfss to simulate so. The guys using hfss don't have the idea to do so.

Can you please say in details how to do that? I'm beginner in hfss.

Hafiz.
