Vitis AI Optimizer License - 3.0 English

If you have previously purchased a license, you can generate the required license file in your Xilinx licensing account. The Vitis AI pruner finds the license using an environment variable called XILINXD_LICENSE_FILE. There are two types of licenses:

Floating License

To install, specify the path in the port@hostname format. For example, export XILINXD_LICENSE_FILE=2001@xcolicsvr1.

Note: This is the step for the client side. For server side operations, run lmgrd to start the license server, as documented in Vivado Design Suite User Guide: Release Notes, Installation, and Licensing (UG973).

Further details related to license server installation and usage can be found in the Xilinx Licensing Solution Center.

Vivado Design Suite User Guide: Release Notes, Installation, and Licensing (UG973), while intended for Vivado installations, provides additional detailed instructions that are also relevant for installation of the Vitis AI Optimizer license.

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, separate them with 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.
