Configuring Linux License Servers Chapter 3: License Configuration
Configuring Linux License Servers
Linux servers use a USB security key as part of the software licensing mechanism.
Once you have installed the key and the corresponding driver, you can
set up the Linux license server as described here:
• Updating the License File for Linux Servers, on page 3-13
• Setting the LICENSE_FILE Environment Variable, on page 3-14
• Starting the License Manager Daemon on Linux Servers, on page 3-15
When you use a Linux machine as your license server, note the following:
• Not all versions of the Synopsys FPGA tools are compatible with the
Linux license server daemon. See the Synopsys web site for Synplicity
products (http://www.synplicity.com/products/products_licensing.html)
for compatibility information.
• For redundant server configurations, it is best not to combine Linux
servers with other servers.
Updating the License File for Linux Servers
You can set up a Linux machine to manage server-based node-locked or
floating licenses. The license clients can be Linux, Windows, or Solaris
machines. The first step in configuring a Linux machine as a license server is
to set up the license file.
1. Create a license file.
– Create a license.dat file in any directory EXCEPT in the Synopsys FPGA
software installation directory (install_dir). If you put your license file in
this directory, the file will be overwritten by future installations and
upgrades to the software.
– Cut and paste the emailed licensing information or enter the
information from the Authorization Form into the license.dat file.
2. Update the SERVER line in the license.dat file with the host name of your
server.
The syntax of a SERVER line entry varies, depending on the dongle you
are using:
