What is a floating or server license?
What are the various parts of the license?
A network floating license allows you to use a license from any machine that can access the identified license server.
An encrypted "key" is locked to a license server host that runs the FLEX license server daemon.
The license is "counted," meaning that the FLEX license manager keeps track of the number of "seats" hosted by that server.
Network Floating Licenses are locked to a license server host running the FLEX license server daemon.
A floating license is counted, which means there is a quantity entered in the "count" field of the FLEX license equal to the number of "seats" hosted by that server.
A license is checked out per unique user.
Therefore, if Joe and Bob are running PAR on two different machines at the same time, two ISE seats will be checked out.
For example, the license below allows for 10 seats of the PlanAhead tool, the ChipScope Pro tool, and/or the ISIM tool to be run simultaneously.
The following table explains the parts of a floating license file.
