ADS 2011 EM Basics (v2 October 2011)
LAB EXERCISE 2 EM Basics (Momentum)
Topics:  EM simulation in ADS, focusing on Momentum, including substrate and
port tups, 3D viewing, visualization, and more.
Audience:  Engineers who have a basic working knowledge of ADS 2011, have completed the prerequisite cour, or who require EM training.
Prerequisites:  Completion of the cour, Workspaces and Simulation Tools  or equivalent experience, including ADS layout skills.
Objectives: Be able to t up and run EM simulations from ADS layout,
including creating a substrate and defining Technology layers and materials.

1. Create a New Workspace and Layout
a. In the ADS Main window, u the wizard to create a new workspace:  File > New > Workspace or u the icon.  Name the workspace and library: My_EM_wrk  - add only the Analog/RF  library as shown here and finish.面瘫是什么原因引起的
b. Create a new layout using the default cell name: cell1, as shown here.
c. In the Layout window, lect Options > Technology > Material Definitions . When the dialog appears, lect the Dielectrics  tab – notice it is empty.  Of cour, if you are using a PDK or library with substrates already tup, then you might be able to e some materials listed here. This lab will show you how
to create materials for u with a substrate.
2.Define  Dielectric Materials:  Technology File
a.Click the Add Dielectric button and a default name (Dielectric_1) will be
added.  Next, change the Real value = 6 (Permittivity) as shown here and click Apply.  You could t other values but this is enough.
click on Alumina from
the list of pre-defined
dielectrics.  Click OK
and your two dielectrics

Notice that you can change
the type, but leave it as
Svensson/Djordjvic.

3. Draw a layout: 2 metal strips and a via
a. In the layout window, draw this simple design  using three layers and the values in mils  shown here.  Change the entry layer as needed to draw two rectangles (u Cond and Cond2) and a centered circle (u Hole). Note that

b. Save the layout when you have finished – you will add pins/ports later.
4. Open the EM Simulation Setup
a. Select the EM Simulation Setup icon in layout to open the EM Setup dialog (shown here).
b. Notice the yellow  caution signs next to the Substrate and Ports icons. This means that the two items have not been
specified and you cannot run the simulation yet.  Read through the Setup Overview quickly  then clo the EM tup. Next, you will open the
Substrate editor and define a substrate for your layout.
5. Add a new Substrate
a. NOTE on substrates: You can u or copy substrates from any飘扬近义词
library in your workspace.  But for this workshop you will create a new substrate so that you are more familiar with how the editor works.  b. In the Layout window, click the Substrate Editor  icon and click OK.  Then click OK  again to u the default name (Substrate1) for your substrate.
c. Notice that a Template for 25 mil Alumina will be ud – this is a starting point.
