SCL Supported OS

For SCL, Synopsys recommends single (not redundant) license servers with the following system hardware & configuration:

  • SCL 2018.06-SP1
  • Recent AMD or Intel x86_64 processor
  • OS: CentOS or Red Hat Enterprise Linux 7.6
  • Multiple cores (modern CPU with four or more cores)
  • 2 GHz CPU speed or better
  • 8 GB of RAM
  • 2 Gbps Ethernet card & switch
  • ext3 or ext4 filesystem
  • Adequate file descriptors (typically 8192 or higher)
  • A physical machine is recommended over a WAN


  • Other OS platforms are supported (see table below), but are recommended only for LAN servers with small quantities of licenses.
  • The btrfs and reiserfs filesystems are not supported.
  • 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.

  • 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 6.6 should also run on RHEL 6.9. And a tool supported on CentOS or RHEL 7.3 should also run on RHEL 7.6.
  • Synopsys relies on the OS vendors' binary compatibility claim and supports running higher minor versions.
