Need help for ADS layout

I am designing a SPDT switch. But i cannot simulate capacitors/inductors (With/without artwork) in layout momentum along with the design. How can i simulate RLC components in layout.Is it necessary to simulate momentum for my design. Kindly comment thankyou

You can use a layout component.
Layout Components for Momentum - ADS 2009 - Agilent EEsof Documentation Center

U can either use the layout components or u can do EM co-simulation..

To do momentum simulation for a simple SPDT depends on what is the frequency of operation?

How using ADS to created DGS

Just subtract the 2 objects created to get ur required DGS..

Is there any information about How to use ADS to creat DGS
