License File
- To use QuestaSim with Radiant 2024.1 and Diamond 3.14 or later, ensure that you have the feature "latticeqsim" in your license file. If none, it is included in the Radiant free license and Diamond free license.
- For floating license, edit your license file to indicate the SERVER and DAEMON details of both "lattice" and "saltd". See the example below.
- If in case that you have a license file with "DAEMON mgcld..", you can replace "mgcld" with "saltd" then add the path to saltd. SALTD daemon supports both QuestaSim (latticeqsim) and ModelSim (latticemsim).

Environment Variables
- Ensure that you have the "SALT_LICENSE_SERVER" environment variable set up with the correct license path (applicable to both node-locked and floating licenses).
- LATTICE_LICENSE_FILE supersedes LM_LICENSE_FILE. If you are having license checkout errors but believe that you are pointing to the correct license, double-check LATTICE_LICENSE_FILE in Registry Editor.
