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

• Recent x86_64 or SPARC processor
• OS: 64-bit Red Hat Enterprise Linux 4.8/5.x or Solaris 10
• Multiple CPUs or cores
• 2 GHz CPU speed or better
• 4 GB of RAM
• 2 Gbps Ethernet card & switch
• Adequate soft file descriptors (typically 8192)

Note:

Other platforms are also supported, but are recommended only for small quantities of licenses. For details on Synopsys recommendations, see the SCL Combined Vendor Daemon Migration Checklist.

Supported SCL Platforms by Operating System & Platform Keyword

For a list of Operating Systems supported under SCL 11.x, see the table below.

IMPORTANT:
SCL 11.3 or later is required to serve cvd-format licenses for tools based on the arcd or mwflexd daemons.

SCL 11.2 or later is required to serve cvd-format licenses for tools based on the Coware, Synfora, or VaST daemons (cowared, synforad, vastlmd).

SCL 11.1 or later is required to serve cvd-format licenses for tools based on the Synplicity synplctyd daemon.

The following limitations apply:

• For ARChitect and MetaWare tools, use only 32-bit versions of SCL for Solaris and Linux platforms.
• For CoWare, Synfora, and VaST tools, use only 32-bit versions of SCL for Solaris and Linux platforms.
• For Synplicity tools, if you are using a Solaris SPARC platform, use only the 32-bit "sparcOS5" binary.
