Description

What are the locations / paths that Vivado software tools check when looking for a license, and what is the search order?

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

Trusted Storage on local machine (Activation based Licenses)

2

%HOMEDRIVE%\.Xilinx\*.lic $HOME/.Xilinx/*.lic

4

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

6

  • To use a license for both ISE DS and Vivado, the license should be in trusted storage:
    Located in %HOME%\.Xilinx or $HOMEDIR/.XILINX or pointed to with the XILINXD_LICENSE_FILE or LM_LICENSE_FILE environment variable.
  • 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 location of %HOMEDRIVE%\.xilinx on a Windows Operating Systems is typically C:\.xilinx
  • The VLM 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.
