hosting remotely. |
| DAEMON lattice daemon_path |
VENDOR lattice |
Current licenses use a VENDOR statement. The daemon path
may still be specified, particularly on Linux systems. |

Quick Installation Guide for Windows
Follow the steps for your license type. For full installation instructions, please visit the respective Software pages and refer to the installation guide.
Node-Locked License
Licensed to a single machine.
- Save the .dat or .lic file to your software install folder (e.g. <sw_install>\license\license.lic).
- Point your environment variable to that file:
LATTICE_LICENSE_FILE = <sw_install>\license\license.lic
- Open the Radiant tool. Once the license checks out, the tool opens.
Get a Node-Locked License |
|
Floating License
Served to multiple clients from a license server.
- Edit license.lic to set the client-connection port
(e.g. SERVER this_host 123456789098 7788).
- On the server, save the attached file to your software install folder
(e.g. <sw_install>\license\license.lic).
- Open LMTOOLS.exe at <sw_install>\ispfpga\bin\nt64. Complete the Config Services tab,
then start the server in the Start/Stop/Reread tab.
- On the server and client, set LATTICE_LICENSE_FILE to port@server_name.

License Server Setup for QuestaSim Lattice Edition
For a QuestaSim/ModelSim license, edit the QuestaSim/ModelSim DAEMON line, replacing put_server_name_here with the server's hostname and path_to_mgcld or path_to_saltd with the
path to the QuestaSim Lattice Edition vendor daemon. For QuestaSim, the path is:
<install_path>/questasim/license_server/saltd
