  • 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.
