In the Questa* FPGA Edition simulator and Questa* FPGA Starter Edition simulator version 2024.1, you might see this error or the following error if you are using the MGCLD daemon v11.16.4
“Unable to checkout a license. Make sure your license file environment variable (SALT_LICENSE_SERVER, MGLS_LICENSE_FILE, LM_LICENSE_FILE) is set correctly”
To avoid this error, upgrade to the Siemens* Flexlm (SALTD) daemon v11.19.5
Download the daemon from the download page
There is a change to the Siemens* License in v11.19.5.0. If you’re running a floating license server for Siemens* licenses, manually change the VENDOR daemon line in the license file from mgcld to saltd, for
example: VENDOR saltd <path to saltd>
Note: Do not change any of the INCREMENT lines. Leave the INCREMENT lines with the original vendor daemon name (mgcld).
