  • Adequate file descriptors (65535 or higher)
  • For WAN servers, a physical machine is recommended  


  • Certain other OS platforms are supported (see table below), but are recommended only for LAN servers with small quantities of licenses
  • Virtual machine setup is not recommended over a WAN as this can impact server performance
  • Docker, Singularity, and other containers are not compatible with SCL
  • Redundant server setups are not recommended
    • If used, they should be used only on LANs
    • If used, the PRIMARY_IS_MASTER keyword should be added to the end

  • Synopsys builds its products on a selected "base" version of each operating system.
  • Operating system vendors guarantee that applications compiled on a lower minor version of an operating system will be binary-compatible with higher minor versions of the same operating system. This means that an application supported on OS version X.Y should run on OS version X.Z. For example, a tool supported on CentOS or RHEL 7.3 should also run on CentOS or RHEL 7.9.
  • Synopsys relies on the OS vendors' binary compatibility claim and supports running higher minor versions.
