There are two types of license: floating license and node-locked license. The VAI Pruner finds licenses using an environment variable XILINXD_LICENSE_FILE. For floating license server, you need to specify the path in the form port@hostname. For example, export XILINXD_LICENSE_FILE=2001@xcolicsvr1. For node-locked license file, you need to specify a particular license file or directory where all the .lic files located.

To specify a particular file:
export XILINXD_LICENSE_FILE=/home/user/license.lic
To specify a directory:
export XILINXD_LICENSE_FILE=/home/user/license_dir
If you have multiple licenses, you can specify them at the same time, each separated by a colon:
export XILINXD_LICENSE_FILE=1234@server1:4567@server2:/home/user/license.lic

For node-locked license, it can also be installed by copying to $HOME/.Xilinx directory.
