The Vitis AI pruner finds the license using an environment variable called XILINXD_LICENSE_FILE. There are two types of license:

Floating license
To install, specify the path in the port@hostname format. For example, export XILINXD_LICENSE_FILE=2001@xcolicsvr1.
Node-locked License
To install, specify a particular license file or directory where all the .lic files are 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, specify them at the same time separated by a colon:

export XILINXD_LICENSE_FILE=1234@server1:4567@server2:/home/user/license.lic

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