Choose Advanced Design System > Release Notes: 2008

Note the Changes in ADS 2008

Important If you have systems running older versions of ADS, see Changes in ADS 2008 for a brief description of changes in the latest ADS versions and their impact on systems with older versions installed.

Changes in ADS 2008

Update and Maintenance Software Releases

Update releases provide specific new features plus all the defect repairs normally found in a Maintenance Software Release (MSR). Since the Update release contains all the defect repairs of the MSR, MSRs will no longer be available.

An Update release is an entirely new installation of ADS and is installed in its own directory. Therefore, if disk space is an issue, uninstall your previous version of ADS before installing an Update. If disk space is not an issue, you can install an update release in its own directory. Although your ADS 2008 licenses will work with ADS 2008 Update releases, you may need additional licenses to run multiple releases concurrently.

Check the System Requirements

Be sure your hardware and software configuration meets the following minimum hardware and system requirements to install and/or run ADS, including RAM, disk space, operating systems, patches and updates, etc. Keep in mind that minimum requirements are just that, and they may not provide adequate performance and responsiveness. For the latest system requirement information, refer to the UNIX and Linux Installation document on our website at:

http://www.agilent.com/find/eesof-docs

System Requirements

User Complied Models

For dynamic User Compiled Models, recompilation is required only for platforms where the compiler has been upgraded. If you are doing 32-bit models, going from 2006 Update to 2008, the compilers have been upgraded for Sun and Linux so recompilation is required.

For static User Compiled Models, recompilation is required for every upgrade.

The following table shows the required compilers for the current release and back to ADS 2004A:

Checking the Operating System

To determine the version that you are currently running, at the system prompt type:

uname -r (All UNIX and Linux platforms)

Get Codewords for ADS 2008

You must obtain new FLEXnet license codewords to run ADS 2008. You will be able to run only those items for which you have codewords. Before requesting codewords, please review the information in Special License Issues.

Note As with most EDA software, each copy of Agilent EEsof software operating simultaneously requires a license for the features being used. This is true whether the software is being run on separate computers, different processors within one computer, or different cores within a processor: each concurrent copy requires a license.

You can request codewords on the Web at:

http://www.agilent.com/find/eesof-support

Scroll to Business Support/EEsof Codewords and select EEsof Codeword Request.

The codewords are then emailed to you in a license file called license.lic.

The hardware key is generally shipped with the software disks. If you do not have one, contact Agilent EEsof Business Support at 1-800-507-6274.

For details on both methods of securing codewords refer to Setting Up Licenses.

For details about license codewords required for simulators, design libraries, components, and other ADS products, see the following table.

License Codewords

Special License Issues

Please consider the following issues before requesting a license.

Linux Systems

If you will be using your LAN card's Ethernet ID to run the FLEXnet licensing system on your PC and you have more than one network card (such as a permanent LAN card and a removable WLAN card) inform your Agilent sales representative to assist you in selecting the correct ID when you request licenses. Use the following command to read the ID, and copy the address returned for Ethernet HWAddr. Then ask the Agilent EEsof Business Support to tie this ID to your ADS codewords when you submit your Codeword Request Form.

/sbin/ifconfig

Back Up Data from Previous Installations

You can retain earlier installations of ADS and ADS 2008 in separate directories on the same machine, but you cannot install version 2008 over a previous ADS installation. This also applies to an Early Access (Beta) 2008 version.

Before you delete a previous installation:

• Copy your projects, customized configuration files, and other data.
• Copy your license file from the <install_dir>/licenses directory.

For details on running multiple ADS versions, refer to Using Multiple ADS Versions.

Check Available Memory

You need a minimum of 512 MB of memory installed on your system. More memory results in better overall system performance for some design work.

Linux Systems

To check the amount of memory on your system, enter the following command at a command prompt:

/bin/dmesg

Look for the Memory line which includes the amount of available memory.

Solaris Systems

To check the amount of memory on your system, enter the following command at a command prompt:

/usr/bin/dmesg | more (Solaris)

Look for the avail mem= and mem= lines.

This command lists the messages displayed during the last boot of the system.

Check Available Disk Space

The amount of disk space required depends on the ADS products that you want to install. Approximately 3.5 GB of disk space is required to install all ADS products. To display the available disk space, at the prompt enter the command for the workstation you are using:

Note ADS requires at least 20-30 MB of free disk space under /tmp and var/tmp to work properly.

Checking Swap Space

The recommended minimum swap space is 300 MB. Very large designs, and designs with many hierarchical levels, could require more.

To check the current amount of swap space on your system, enter one of the following:

Defining an Install Location

Be sure you have permissions to write to the disk drive on which you want to install ADS.

• You do not need to install as root, although you may need root privileges to mount and unmount the installation DVD.
• If installed as root, all ADS files should have at least read permission for all users.

You can re-run the installation program to install items you chose not to install the first time through.

For details on install steps and options, refer to Installing Advanced Design System.

Note The installation program does not support cross-platform installations. Use the correct platform-specific installation disk or download for your system.

Dataset Types

Due to a change that removed the former limitation on dataset file sizes, datasets created by ADS 2008 (and subsequent releases) are not readable by earlier versions of the ADS. However, two new command-line programs are available that can identify (and if necessary change) the type of a given dataset.

dstype

The dstype program identifies the type of one or more specified datasets.

Usage:

dstype <dataset_filename> ...

This program displays the type of the specified dataset filename(s). The filenames must include the .ds dataset file extension. UNIX wildcards may be used in dataset filenames. More than one filename can be specified on the command-line. Example:

$ dstype test.ds hbtest.ds junkfile.ds
test.ds: Agilent EEsof dataset, Release 2008 format
hbtest.ds: Agilent EEsof dataset, Release 2006A format
junkfile.ds: unknown file type (not a valid dataset)

The types are referred to as Release 2006A format and Release 2008 format. Release 2006A format applies to a dataset produced by any version of ADS before 2008. The Release 2008 format applies to a dataset produced by ADS 2008 or later versions.

dsconvert

The dsconvert program performs type-conversion between the two data set types.

Usage:

dsconvert [-f] <from_dataset> <to_dataset>

Where <from_dataset> and <to_dataset> are the source and destination dataset filenames, respectively, including the .ds extension. Only one file can be converted at a time; do not use wildcards with the dsconvert program.

To prevent accidental overwriting, the destination dataset must not exist, unless the -f option is given. The -f option forces the overwrite/deletion of an existing destination dataset.

Conversion can be in either direction:

• If <from_dataset> is in Release 2008 format, the program converts it to the Release 2006A format.
• If <from_dataset> is in Release 2006A format, the program converts it to the Release 2008 format. (However, it is not actually necessary to perform this type of conversion, as ADS 2008 is capable of reading datasets created by earlier versions.)

Supported Features on 64-bit Operating Systems

The following simulators are supported when ADS is installed on a 64-bit Solaris or Linux operating system:

• 64-bit Analog/RF
• 64-bit Momentum
• 64-bit Ptolemy

If you want to run these simulators in 32-bit mode or you want to use features that are not available on a 64-bit operating system, you can launch ADS in 32-bit mode. See Using 32-bit Simulators on a 64-bit Operating System.

The following tables provide details about the supported features when ADS is installed on a 64-bit operating system:
