Solid Edge About Siemens Advanced Licensing Technology (SALT) and Siemens License Server (SLS)

This is a guide to help you get started with understanding, configuring and managing the Siemens Advanced Licensing Technology (SALT) and Siemens License Server (SLS).

Siemens PLM customers may still access the legacy Siemens PLM Licensing software to support previous product releases.

Beginning with the forthcoming SALT 2.0.0 release, all Siemens Digital Industries Software products will begin migrating to SALT over the course of a year.  The customer may choose to adopt the Siemens License Server (SLS) in advance of these migrations or as product requirements dictate.  Please refer to your product's Release Notes for more information.

Siemens Digital Industries products are moving to a new licensing model. This includes new licensing software, new license files, and new ways of setting up licensing (i.e. SALT).  This change affects both Siemens EDA (Mentor) and Siemens PLM tools.

SALT includes the following:

• A complete licensing model based on Revenera's FlexNet and customized functionality that support Siemens Digital Industries applications.
• A new licensing API for Siemens EDA and PLM applications for utilisation.
• Support for applications to use the SALT API with mgcld, ugslmd and saltd vendor daemons and licenses.
• A license server - Siemens License Server (SLS) and installer that supports both legacy Mentor and Siemens vendor daemons (mgcld and ugslmd) and a new vendor daemon (saltd).
• A license delivery model using Siemens Support Center.
• Utilities to support the administration of the SALT environment (e.g. LMTOOLS, lmutil, getcid, etc.)

The Siemens License Server installs the saltd vendor daemon to support Siemens Digital Industry Software products. The saltd vendor daemon is implemented with the Common Vendor Daemon functionality that enables it to serve the following vendor daemon license files:

• Common Licensing Toolkit (CLT) - (ugslmd)
• Mentor Standard Licensing (MSL) - (mgcld)
• Simcenter STAR-CCM+/SPEED/STAR-CD/BDS- (cdlmd)
• Simcenter HEEDS - (RCTECH)
• SALT - Siemens Advanced Licensing Toolkit (saltd)

The installer will install the license daemons (lmgrd and saltd), license utilities and documentation into a common location depending on platform, import any license files you have for the supported vendor daemons and start the license manager for SALT.

The default installation location on Linux is /opt/Siemens/LicenseServer.  The default installation location on Windows is C:\Program Files\Siemens\License Server.

Installation instructions are found in the "Siemens Digital Industries Software License Server Installation Instructions".

Once your Siemens License Server (SLS) is installed and configured, your applications will be directed to checkout licenses from SLS based on one or more environment variables, depending on the licensing implementation on which they are built.  In short, applications built with legacy CLT APIs will continue to use their respective environment variables for licensing  - SPLM_LICENSE_SERVER (PLM), SE_LICENSE_SERVER (SOLID EDGE) - to point to the license manager daemon (lmgrd).  For applications built with SALT, these will use the SALT_LICENSE_SERVER environment variable.  Managing multiple versions of Mentor and Siemens applications in the same environment will entail setting multiple variables for licensing.
