ADS 2011 New Capabilities: Easy EMSetup, Multi-technology, and more....

Easily simulate modules and multi-chip designsEasily select models for simulationMore efficient EM setupADS 2011 retains the same ADS personality. What’s the same? …

OverviewADS 2011 delivers many exciting new features for all ADS users with breakthrough newcapability for multi-technology (adsoverview) co-design like that inherent in RF modulesand system-in-package (SiP) designs.

ADS 2011 builds upon the recent ADS releases, expanding Agilent’s completeMMIC/Module Desktop Flow to deliver the industry’s leading, complete, integrated, end-to-end product realization RF design solution.

ADS has changed to meet the needs of increasing complexity and integration.Commercial wireless and Aerospace/Defense Industries are rapidly moving fromsingle-packaged MMICs to larger, more complex ICs in multi-chip RF modules.Today's flows combine multiple, poorly integrated tools, which are not able toaddress multiple technology design and verification.The IC, laminate, package and PCB system need to be designed together,interactively.Electro-magnetic interactions between substrates need to be modeled.

Although most of ADS 2011 looks and feels the same, some important changes have beenmade to support the breakthrough technology in this release. Your initial success andproductivity with the release will be greatly enhanced by viewing a short introductorytutorial. We highly recommend viewing this before you start using the new release.

ADS 2011 Quick Start Video Tutorial

Easily Simulate Modules and Multi-Chip DesignsWe have incorporated Workspaces (adsoverview) and Libraries (adsoverview) into theADS environment to support simulating modules and multi-chip designs.

ADS users are no longer restricted to a single project folder. This makes it easy to createmulti-technology designs and designs containing IP from multiple engineers. You cancreate designs that use components from multiple processes (PDKs). The designs will usethe technology defined in the library/PDK. Duplicate component names are supported aslong as the parts are in different libraries.

Easily Select Models for SimulationYou can now easily simulate variations of a design without activating and deactivating.This concept, called Dynamic Model Selection (adsoverview), means you can simulate thesame design with different models. For example, you could have different versions of thesame filter, such as one using micro-strip elements, another that is the layout and usesMomentum simulation, and another using lumped components. With one right-click ofyour mouse, you can swap between these different models using the same simulationsetup, or you can automate how designs are simulated with a policy.

More Efficient EM SetupADS 2011 has a redesigned EM user interface for both Momentum and FEM which providesa more streamlined use model for creating Substrates (adsoverview), defining Ports(adsoverview), and generating EM Models (adsoverview). EM setups (adsoverview) areeasier to configure and can be reused.

Circuit Simulation at a Glance What is the Same

In most cases you will see no change to how simulations are setup and run in ADS2011.You should be able to convert your project to a workspace, open the schematic, andsimulate.When creating new designs, if you use the system default names for views("schematic") the system will behave very much like previous releases.Data display has the same use model with a few popular enhancements like SmithChart zoom.

What is DifferentUsers now have more flexibility in dynamically selecting models for simulation.You can have more than one schematic associated with your design. The netlist iscontrolled by the hierarchy policy.Libraries make it easy for multiple users to work on the same design. Names onlyneed to be unique within the library.


11

Layout at a Glance What is the Same

You will find that most of the user interface in the layout window has stayed thesame.You should be able to migrate projects into workspaces and start editing the layout.When creating new designs, if you use the default view names ("schematic" and"layout") the system will behave very much like previous releases.The same physical verification tools are available in ADS layout (ADS Desktop DRC,ADS Desktop LVS, Check Nodal Connectivity, Check Physical Connectivity, DesignSynchronization, and the 3D Viewer).

What is DifferentObject handles make it much easier to edit shapes.You have the option of creating multiple layout views of the same design.Design synchronization is now based on instance-name comparison, so you cancompare any two schematic/layout views.

Workspaces, Libraries, Cells, and ViewsAdvanced Design System (ADS) now uses the workspace, which is a folder/directory, tostore and organize your design work. It is a replacement for the ADS Project used in ADS2009 Update 1 and earlier versions. A Workspace is similar to but not the same as an ADSProject. A workspace contains design data, simulation results, data display files, and otherdata files. The main difference between a Workspace and a Project is that, for aWorkspace, your design work is stored in libraries instead of the networks directory.

Workspace > Library > Cell > View Hierarchy

NewStructure

Description

Workspace A workspace is a folder similar to a project. A workspace contains your schematics (but nowwithin libraries), data displays, preferences, and configuration files.

Library A library is a folder that groups cells (defined below) that have a common technology library.When you create a workspace, you define its libraries by specifying the path and you can alsospecify the technology (layers, units, etc.) to use. Adding two or more libraries to yourworkspace makes it easy to handle multi-technology designs such as RF system-in-packagemodules.

Cell A cell is a folder and replaces a design file in the old networks directory. Cells act as a collectorfor schematics, layouts, symbols and other view types. A cell is in a library and usually containsdifferent views of a design including layouts, schematics symbols, EM setups, and EM models.When you create a new schematic or layout, you can name the cell.

View A view is one of the representations or models of the cell. For simulation, you can switchbetween views using Dynamic Model Selection. There are several types of view. A cell cancontain zero or more of each type. Some common ones are:Schematic is circuit schematicLayout represents the physical structureA symbol represents all views in the cell. Usually a single symbol is all you need for the cell,but multiple symbols can be useful. You can click on a symbol to determine which view youwant to see or simulate.emSetup contains the EM simulation parameters for the cell.emModel contains EM simulation results that can be used as a model of the cell in a higherlevel schematic

ADS Project Vs. ADS Workspace

If you designed a project in ADS 2009 Update or earlier, and wish to use it in ADS 2011,you will first need to convert your project into a workspace (adsoverview).

In this flow, only the circuit simulation of the multi-tech flowhas been emphasized.

In this example, the following PDKs are used in LNA and SPDT design:

Non-Linear DemoKit DemoKit_Non_Linear: is used in MMIC LNA design1.DemoKit DemoKit_V3: is used in MMIC SPDT design2.Antenna and Power Amplifier designs are created in “Antenna_lib” and “PA_lib”3.libraries respectively.Finally the four designs used from four libraries are integrated to see the overall4.performance of the designs in “Antenna_SPDT_LNA_PA_lib” library.

The Antenna_SPDT_LNA_PA_wrk workspace demonstrates usage of multiple PDKsincluded in different libraries, which have some components with the same name. Makesure you have attached the right PDKs DemoKit_Non_Linear and DemoKit_V3 to MMICLNA and MMIC SPDT respectively. Below diagram shows the pictorial view componentsthat have been designed for the front-end transceiver circuit.

Using LibrariesLibraries help organize designs that share a common technologyLibraries prevent name collisions with PDKs and system librariesLibraries make it easy to reference designs created by other people

FeaturesYour Libraries

When creating a new workspace you will be asked to create a library.Selecting the technology for this library is an important step, because all of thedesigns stored in this library will inherit this technology definition.When you create new designs they will reside in this library.

System LibrariesYou need to include the ADS system libraries if you want to use componentsthat ship with ADS.ADS libraries are selected by default when new workspaces are created.

Process Design KitsYou need to include a foundry library if you want to use components from aPDK.Design kits are no longer "installed" and "uninstalled".Each workspace specifically includes the design kits that it needs.Once you specify the location of a PDK, the system remembers it as a FavoritePDK.

Applications for LibrariesA workspace can contain multiple libraries (test benches and design data).A workspace can reference multiple PDKs for multi-technology assemblydesigns.A workspace can reference other people’s libraries for design integration.

UsageAdding a Library

From the main window execute DesignKits>Manage Favorite Design Kits...Select Add Library Definition File...Browse to the <library>.defs.The library will now be listed as a favorite and can be selected when you createa workspace.You can drag and drop parts using the Component Library dialog.

Converting Projects to WorkspacesEasily convert projects to workspacesWorkspaces are similar to projects in that they help organize simulation anddesign dataWorkspaces are an improvement over projects in that they use libraries fortechnology scoping

FeaturesMigration

Bring your data into ADS 2011 by browsing to your project. When you attemptto open the project, the system will automatically ask if you wish to convert theproject to a workspace.The Convert Project to Workspace Wizard steps you through the process ofconfiguring your new workspace.During project-to-workspace conversion, designs from the networks directoryare converted to cells and placed in the new library in your workspace.A pre-scan is performed to identify missing components. Libraries and PDK'smust be added during conversion: Adding them later will not repair componentsthat were not successfully converted.New designs created in ADS 2011 cannot be converted back to the *.dsnformat.

PreferencesADS 2011 has an improved organization for user preferences.User preferences are stored in the workspace (grid display on/off).Technology-related settings (units, layer definition) are now stored in thelibrary.

Some technology related settings (such as color) can be overridden in theLayer Preferences dialog. An settings file will be stored in the workspace forthese overrides

Unarchiving WorkspacesArchived projects have the extension “.zap”.Archived workspaces have the extension “.7zap”.ADS 2011 can directly open archived projects and will automatically begin theworkspace conversion process.

Setting up Multi-Technology DesignsADS 2011 supports creating multi-technology schematics and layouts. Components fromdifferent libraries/PDKs can be placed in a design, and ADS will use the technology fromthe library when performing a simulation and rendering the artwork.

Libraries also provide name scoping. Libraries prevent component-name collisions andallow you to easily assemble work created by different designers.

In the substrate editor, multiple substrate technologies can be combined with othertechnologies. For example

IC in a Package1.IC in a Module2.Module on a PCB3.IC in a Module on a PCB4.

The substrate editor supports multiple stacking levels, flip chip, wire bonding, andbackside mounting.

Multi-Technology Module design is fully supported for EM simulation and the 3D Viewer.Momentum and FEM simulations can be performed on multi-substrate structures.

Multi-Technology for Circuit SimulationThis tutorial will step you through the process of creating a multi-technology moduledesign.

Managing Projects of Different Technologies in a Single Workspace

For circuit based MTM flow, designs based on different technologies are managed inseparate libraries. If the designs are in different workspace, then libraries of thoserespective designs along with the necessary PDKs are added in the current workspace.

Follow the steps below to add a library definition file from the PDKs to a workspace:

From the ADS Main Window, choose DesignKits > Manage Libraries to open the1.Manage Libraries dialog box.Click Add Library Definition File to add lib.defs file, from the PDK library.2.

Follow the steps below to add a library of a design to a workspace:

From the ADS Main Window, choose File > Manage Libraries to open the Manage1.Libraries dialog box.Click Add Library to open the Add Library dialog box.2.Specify the workspace and its respective library that needs to be added.3.Click OK to add the library.4.

Note

To add a particular library of designs to a workspace, you should use Add Library option rather1.than Add Library Definition File.The Add Library Definition File option will add all the libraries of a workspace to the current2.workspace.

In this way, different technologies can be used in a single workspace with the help oflibrary feature and further the designs can be integrated to check the overall performanceof the multi-technology design.

An example is designed to illustrate the benefits of including the libraries in Multi-Technology feature in ADS 2011. Click here (adsoverview) to refer the Multi-TechnologyTutorial for Circuit Simulation (adsoverview).

Multi-Technology for EM SimulationMulti-technology designs can be simulated using Momentum or FEM solvers. Subdesignscan be placed on the base design in the same layout as the nested technology. ADS willsupport any number of stacked technologies. Components at the same level (side-by-side)need to share the same technology.

Below are the steps required to setup a design for multi-technology simulation.


56

Managing Projects of Different Technologies in a Single Workspace

For MTM flow, designs based on different technologies are managed in separate libraries.If the designs are in separate workspaces, then the libraries of that respective designsalong with the necessary PDKs are included in a single workspace. For this you need toadd lib.defs file from the PDK.

Follow the steps below to add a library definition file to a workspace:

From the ADS Main Window, choose DesignKits > Manage Libraries to open the1.Manage Libraries dialog box.Click Add Library Definition File to add lib.defs file, from the PDK library.2.

If a PDK is included in a workspace, it will automatically migrate its substrate in Read onlymode. In order to make any modifications, you need to make a copy of the substrate.

Prepare Sub Design to use as a Nested Technology

Sub design is a design, which is integrated with the base design as a nested technology.

For Momentum simulation, substrate of sub design can be used directly in the base1.design. Additional modifications are required for FEM simulation. For FEM simulation,to limit the design size finite in X-Y direction, substrate layers are represented withfinite size of dielectric via.In the layout view of sub design, it is required to change the artwork as nested2.technology. By using nested technology, the original layout is used and supportslayer mapping. This enables you to use an instance of this layout inside a differenttechnology.

Choose File > Design Parameters in the layout to open the Design1.Parameters dialog box.Select View-Specific Configuration tab.2.Select the Artwork Type as Nested Technology.3.

Creating Multi-Technology Definition from Base Technology

In base technology substrate, sub design substrate is added as nested substrate. Nestinga technology allows you to place a design from another technology into a design of basetechnology. This could be used to place surface mount components on the top or bottomof a printed circuit board. It could also be used to place a flip-chip integrated circuit into amodule. For more information about creating a Nested Technology, see Nested Technology.


57

Follow the steps below to create a nested substrate:

Open the base design layout and choose Options > Technology > Nested1.Technology.The Nested Technology tab is selected by default. Click Add to add a default2.technology top0.

Select top0 and click Open to open the Nested Technology dialog box.3.

In the Nested Technology dialog box:4.Select the sub design library, which will be used as nested technology.1.Select the Orientation and vertical position to place a nested substrate in the2.base substrate. The following table describes the four possibilities:Orientation and VerticalPosition

Symbol Description

Above an interface Places the nested substrate above an interface ofbase substrate

Below an interface with thedesign flipped

Places the nested substrate below an interface ofbase substrate with design flipped

Above an interface with thedesign flipped

Places the nested substrate above an interface ofbase substrate with design flipped

Below an interface Places the nested substrate below an interface ofbase substrate

To use the layers from the nested technology, it is required to specify its equivalent5.layer in this technology. After this, the system treats the two layers as one. Forexample, if you need to make an electrical connection to a layer in the nestedtechnology, you should add an equivalent layer for it. Here it is not required to mapall the layers of sub design, only layers on which Pins, bondwires or other electricalconnects are needed, can be added as an equivalent layer. Click Add EquivalentLayer in the Nested Technology dialog box to add a layer.


58

5.

Adding Nested Substrate in Base Substrate

After defining the nested technology and mapping equivalent layers of sub design intobase design, place the nested technology substrate in base design substrate. In ADS2011.01, the nested substrate can be placed either above or below an interface of thebase substrate. Follow the steps below to place the nested substrate:

In the Substrate Editor dialog box, select the top interface of base substrate and1.right click to select Insert Nested Interface.

On the right hand side of the substrate editor, all the defined nested technologies2.along with their respective substrates will be available in the drop-down menu. SelectNested Technology and Substrate of the sub design from the drop-down menuunder Nested Substrate.

Adding Sub Design in Base Design

After defining the nested substrate, sub design is placed in the base design. You caneither drag-drop the sub design directly layout in the base design layout or place it fromthe Component Library. All mapped layers of nested technology should be listed in layerpreference. Now Pins, interconnecting bondwires and transmission lines can be placed incombined design for FEM or Momentum simulations.
