The following are issues you need to address when migrating from a Cadence® AWR Design Environment®
platform v14 release to an AWR Design Environment platform v15 release. Not all topics
apply to every user. If you are not familiar with a topic or program feature included here, it
probably does not apply to your use of the software. You should read about all of the issues
before developing your migration strategy. You can contact
Technical Support for AWR Products with any
questions. The path to the <Appdatauser> files referenced in this document is operating
system dependent. To view the directory path to your <Appdatauser> files, choose
to display the Directories dialog box, then
Generalized load pull measurements (measurements beginning with "G_") now require the LPL-100 Advanced Load Pull license feature. See Load Pull Licensing Change in Version 15 for details on enabling this feature.
The AWR Design Environment platform v15 software no longer supports Windows 7 and Windows Server 2008 R2 operating systems.
Cadence no longer includes HSPICE in future purchases, maintenance renewals, or term deals. If you are using HSPICE, please work with your local Sales team to investigate alternative options.
The default value for the Circuit Options dialog box APLAC Sim tab Stability Options > Impedance Points for Stability Envelope option is increased to 360. The previous default of 50 is insufficient in many cases.
In v15, IPC socket is introduced as an alternative transport type for remote computing. This new transport type is preferred over the original pipe transport since sockets do not require Windows credentials. When you add a new remote host with transport type as "auto-detect", sockets is now the default transport type.
When migrating the AWR Design Environment platform from v14 to v15, Job Scheduler settings and remote host tables from v14 also migrate from v14 to v15. Remote hosts that migrated over from v14 have pipes set as the transport type. To update the transport type to socket on both user machines and scheduler nodes:
Chooseto open the Job Scheduler Admin dialog box ,or open it from the menu AWRDE program folder.
In the Remote Hosts table, double-click on the remote host entry.
Change the Transport from awr_pipe_ipc to awr_socket_ipc.
Clickto check the connection between the machines. Click to close the Host Verify dialog box, and again to close the Host Details dialog box.
Repeat the steps for each entry in the Remote Host table. When all entries are updated, click , then .
Measurement variables, introduced in the AWR Design Environment platform v14, are not compatible with v13 or earlier versions. Before saving a project as v13, you need to remove measurement variables from measurements.
The data file format for AMP_F and NL_F is expanded, and the two blocks are now interchangeable. Both blocks are backwards-compatible, but the newly added data file tags are not. When back-saving to an older version of the AWR Design Environment platform software, see the documentation for that version for the correct data file format.
The items in this section address moving files and settings from one software version to another. Some of these files and settings are automatically migrated. If the previous software version is not found, up to three major versions back are searched. For example, if migrating to the AWR Design Environment platform v15, AWR Design Environment platform v14, AWR Design Environment platform v13, and AWR Design Environment platform v12 software are searched.
NOTE: Ensure that your Windows® Explorer program is set to show hidden and system files.
Appdatacommon folders must
be in their default locations for files or directories to auto-migrate. Changing their
default locations would involve creating a
redirect.ini file in the
program directory, and is not common.
The migration of Appdatacommon is triggered based on the existence of the
mwoffice.ini file in the
for the newly installed version.
If there is an existing
mwoffice.ini file, no files or
folders are migrated.
mwoffice.ini file does not exist, it is copied from
the previous location if found.
mwoffice.ini file does not exist and an older
version is not found, a new file is created.
The path to each PDK is stored in the
mwoffice.ini file and is
available for any user of that computer. The installation location of foundry libraries is
typically version-independent; the default installation locations are not dependent on the
AWR Design Environment version. These paths are used when opening a project using a PDK or by choosing
All additional files and directories at this location are not copied since they should not be used with the new version of the software.
The migration of Appdatauser is triggered based on the existence of the
user.ini file in the
Appdatauser folder for
the newly installed version. If there is an existing
no files/folder are migrated. No existing files or folders are overwritten.
The following files/folders are migrated:
.ini files located at the top level directory of
user.ini file contains environment settings, custom layout
modes, and other environment defaults.
All XML files located at the top level directory of
Appdatauser. This includes:
customizations.xml - contains your hotkey settings.
UICustomizations.xml - contains your menu settings.
You can reset the menus to the AWR Design Environment platform v15 defaults.
UIDockingLayout.xml - contains settings for how
different windows are docked in the AWR Design Environment platform.
UIToolBarLayout.xml - contains your toolbar settings. You
can reset the toolbars to the AWR Design Environment platform v15 defaults.
materialdefs.xml - There are several pre-set
materials such as FR4, alumina, and GaAs available in the EM interface. If you
modify these settings, the changes are stored in
scripts - Global (available in any project) Visual
models/model64 - Custom models used in the AWR Design Environment
cells/cells64 - Custom cells used in the AWR Design Environment
symbols - Custom symbol files created in the AWR Design Environment
em_models - User-filled X-model tables.
XML - XML libraries installed in the default location.
All additional files and directories in this location are not copied since they should not be used with the new version of the software.
TARGET: License Administrators
AWR Design Environment platform v15 software requires a new license file. You can request
an updated license file by sending an email to
firstname.lastname@example.org with your
company name and a copy of your current license file.
Your AWR Design Environment platform v15 license file is also backwards-compatible to
AWR 2006. If you use a floating license server, your
lmgrd.exe must be version 11.15.0 or later.
TARGET: Users who have local XML libraries (anything outside of the AWR web library)
Many users either choose to install a local copy of the XML libraries or add to
the default installation with other vendor-specific XML libraries. The default
location is the
<Appdatauser> folder. If your XML is in
this location it can be migrated automatically (see “Files Automatically Migrated ”).
Starting in v11, the correct location for these libraries is
Environment\V11.0\XML. There are top level folders for
Circuit Elements and
Blocks. Any XML file located in these top level directories is
automatically used in the AWR Design Environment platform WITHOUT the need to edit files in the
The best way to migrate these libraries is to open your current
sys_lib.xml files in the
Library folder of your old installation and search for any
paths you added to this library (perhaps compare with v14). Find those
libraries and move the top level XML file to the directory listed above to break the
cycle of needing to edit these install XML files.
When model changes are identified, the project can use a model compatibility flag. When you open an old project in a newer version of the AWR Design Environment platform software, the simulation results from the previous version do not change. You can change the model compatibility setting to see simulation results with the old and new model implementation. A dialog box similar to the following displays when you open your design in a newer version if there are models with a compatibility setting in your design.
You can switch between model versions in the Circuit Options dialog box by choosing AWR Sim tab, clicking the button, and then selecting the desired modeling version in Model compatibility version., then clicking the
TARGET: AWR software installers
Most users keep AWR Design Environment platform v14 software installed when upgrading to AWR Design Environment platform v15 to ensure their designs upgrade properly before converting permanently to the latest version.
When you install AWR Design Environment platform v15 software, both versions run. Uninstalling any version may result in registry problems; therefore, when you uninstall, Cadence recommends that you also repair your active installation. One way to repair your installation is to open the Control Panel and then click on the Apps group. Under Apps & features, locate your AWR Design Environment platform installation and select it. Click thebutton to display a dialog box with options for repairing or uninstalling the software. Select the option and follow the prompts.
TARGET: Users of any type of file redirection (changing the default locations for any of the folders used by the AWR Design Environment suite)
In networked environments, some users may choose to change the default location for certain files.
Complete information on redirection is available in the
Guide under "Configuring Program File Locations". If you use this
capability, ensure that you make the same changes in AWR Design Environment platform v15
software that you set up for AWR Design Environment platform v14.
