About Cadence Installation Software

Cadence uses the following installation programs for various delivery and platform options:

• InstallShield installs on Microsoft Windows platform.

• InstallScape installs on UNIX and Linux platforms.

Although these two installation programs are different, they follow the same basic format:

1. Mount or locate your installation media.

2. Run the installation program.

3. Follow the on-screen instructions to install the Cadence software.

4. Perform any post-installation tasks described in your product documentation.

Software Delivery

Cadence uses the following software delivery methodology:

• Individual files are grouped into larger collections called kits. These kits contain additional information used for tasks such as configuration control and file integrity checking.

• Kits are combined in various ways to create products and allow products to share functionality.

• Each kit may contain special configuration code supplied by the product team.

Cadence has developed utilities to manage these kits and the relationships of these kits between the different products.

The Cadence installation software applies updates to the software using the Update/Hot Fix process (for information regarding Update and Hot Fix , see step 2 on page 11). By managing the inter-product and intra-product dependencies, the installation software updates all products in a coordinated fashion.

Installing Software Online

If you are authorized for electronic software distribution, you can download a DVD image using either FTP or HTTP. Alternatively, you can install Cadence software over the Web using InstallScape. See download.cadence.com for more information.

If you are installing Cadence software using a downloaded DVD image, each DVD downloaded is a tarfile, which must be unpacked with the tar (or equivalent compatible) command. The tarfile is not compressed. After you have unpacked the files, use InstallScape or InstallShield to install the Cadence software on UNIX or Windows systems, respectively. See step 7 on page 16 for more information.

If you are installing Cadence software over the Web using InstallScape, refer to the InstallScape documentation located at download.cadence.com.

Important Reminders

• Always use Cadence installation software to install and update your Cadence application software. If you modify or install application software without using the Cadence installation software, the data files used to determine the status of each product can be made obsolete.

• Always use the installation software shipped with the application software you are installing. Older versions might not work with the latest control files.

• Always install products from different releases into separate directories. To ensure that different releases do not corrupt the installation data files, the Cadence installation software does not let you install products from different releases into the same directory.
