  • Other OS platforms are supported (see table below), but are recommended only for LAN servers with small quantities of licenses.
  • Docker, Singularity, and other containers are not compatible with SCL.
  • Virtual machine setup is not recommended over a WAN as this can impact server performance.
  • Redundant (triad) server setup is not supported over a public or private cloud
  • Redundant server setup is not supported when the SCL server is a virtual machine

  • 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 7.6 should also run on CentOS or RHEL 7.9.
  • Synopsys relies on the OS vendors' binary compatibility claim and supports running higher minor versions.
