Licensing - What will XLCM tell me about Xilinx license keys that it finds?


What information will the Xilinx License Configuration Manager (XLCM) tell me about Xilinx license keys that it finds?


XLCM provides the following informational fields for each license key found:

  • Feature - The feature, increment, or package name of the license key.
  • S/W or IP Core - Indicates weather the license key is for a Xilinx Software application or enables the use of a LogiCORE IP Core.
  • Version Limit - Indicates the cutoff date (year and month) for released software and updates. The license will not enable a software update released after the date. Older LogiCORE IP Core licenses will have a single number, for example,'1.0' indicating that the license is good for that specific version of the LogiCORE IP Core only.
  • Expiration Date - Indicates when the license expires. Typically used for trial or evaluation licenses.
  • License Type - Indicates if the license is a Floating or a node-locked license.
  • Count - Indicates the number of seats enabled for the license feature. Because node-locked license keys are only valid for a single computer, they will generally be uncounted.
  • Licenses in Use - The number of seats currently checked out for this feature.
  • Information - Echoes the value of the VENDOR_STRING line in the license file. This string might give more detailed information about the feature, when it was generated, and who it was generated for.
  • Server Name - For floating licenses, this field indicates the port number and server name where the license key was found.
  • File Name - For node-locked licenses, this field indicates the directory and file name where a license key was found.
  • Host ID - Indicates the Host ID to which the license key is locked.
  • Host ID Matches - Indicates whether the license key Host ID matches a Host ID connected to the machine running XLCM.
  • License CRC - Indicates if the license key appears to be valid for use on the current machine. NOTE: The license expiration date is not considered in this calculation.
  • Search Order - The order in which Xilinx License keys were located.
