Install SCL

Summary of the necessary steps, which are detailed in Synopsys Licensing QuickStart Guide

  • Download the installation file for Synopsys Common Licensing (SCL) from the Synopsys SolvNet portal.

  • Install the SCL application.

    • Run the installer with Administrator privileges. You can do this by right-clicking the file and choosing Run as administrator.

    • You need to enter your site ID - it can be found in your license key file.

  • Customize the license key file to reflect your environment and place it in the expected location.

    • Remember to specify the port number in the VENDOR line, so that it is not randomly assigned at each start.

  • Open the two ports in the firewall: the SERVER and VENDOR ports should be open for incoming and outgoing TCP traffic.

    • Client users need to know the SERVER port number.

  • Start the license server and verify that it is running correctly.

    • If this is not the first time you start SCL, make sure to shut down snpslmd before proceeding:

    • At any time, you can check if SCL is running by starting the lmutil program, and typing lmstat in the resulting terminal.

Note

During the setup of the license server you may get the error message shown in the image below. You can safely ignore it - the license server should be configured correctly.
