2007: Proteus products on the Sun SPARC Solaris platform

Dear Synopsys Customer:

If you are using the Synopsys Proteus products on the Sun SPARC Solaris platform please read this letter carefully.

Due to the decline in the demand of the Sun SPARC Solaris platform for Proteus, the Synopsys Proteus product release Y-2006.09-SP3, scheduled for September 2007, will be the final shipping release for this platform. Subsequent new releases will no longer support the Sun SPARC Solaris platform. Older releases of the Synopsys Proteus product family will continue to support the Sun SPARC Solaris platform.

By providing you with this notice, we hope to help minimize your inconvenience in implementing this change. If you are affected by this change, Synopsys is available to assist you in the migration of your Synopsys products to another supported compute platform.

By providing you with this notice, we hope to help minimize your inconvenience in implementing this change. If you are affected by this change, Synopsys is available to assist you in the migration of your Synopsys products to another supported compute platform.

General information on compute platforms and versions supported by Synopsys products is available at the Synopsys web site.

Please refer to the Proteus product family documentation for product specific information concerning compute platform support.

If you have any further questions or need assistance, please feel free to contact your local Synopsys CAE or Account Team.

Thank you for your continued support.

Sincerely,
