Installation is completed for the Libero SoC tools from Microchip, and those tools
are ready for use. If you plan to use the bundled third-party tools, such as Siemens
ModelSim ME Pro and Synopsys Synplify Pro, note that in addition to the
LM_LICENSE_FILE variable, which applies to all vendors,
Synopsys license can be set using two vendor-specific variables (see the following
table).
Important: Libero SoC versions 12.2 and
later do not impose any restriction with the Synplify Pro tool. For Libero SoC
versions 12.1 and earlier, Synopsys tools do not work beyond the distance of 50
miles or beyond the geographic locations.
