What are the search order and locations / paths that ISE Design Suite software tools (other than CORE Generator) look for a license?

For the IP core license search order, see (Xilinx Answer 42508).

For Vivado license search order, see (Xilinx Answer 62334).

Solution

ISE software applications (including XLCM) look for FLEX licenses in the locations and order listed in the following table:

Order

Linux Location

1

All the places listed by the environment variable XILINXD_LICENSE_FILE, if set.

All the places listed by the environment variable XILINXD_LICENSE_FILE, if set.

Location cached for XILINXD_LICENSE_FILE

3

All the places listed by the environment variable LM_LICENSE_FILE, if set.

All the places listed by the environment variable LM_LICENSE_FILE, if set.

8

%XILINX_EDK%/data/core_licenses/*.lic (for each entry in %XILINX_EDK%)

XILINX_EDK/data/core_licenses/*.lic

9

All the places cached in %HOMEDRIVE%\.Xilinx\license_info.cache, created when you click 'Set' to save the XILINXD_LICENSE_FILE value in xlcm.

  • The location of %HOMEDRIVE%\.xilinx on a Windows Operating Systems; this is typically C:\.xilinx.
  • The entries in the environment variables can be files, directories, and/or PORT@HOST values.
  • Directories will be searched for *.lic
  • Licenses found in the same directory are searched in alphabetical order.
  • License features within a single file are searched in the order in which they appear in a license file.
  • The XLCM Manage Xilinx Licenses tab has a search order column that numbers each license key according to the precise order in which it was located.

Note: The search order does not necessarily determine what license will be used first when there are multiple licenses for the same feature. 

See (Xilinx Answer 44024) for the rules of license precedence.
