LICENSE FILE TROUBLESHOOTING
83 ■ ALTERA SOFTWARE INSTALLATION AND LICENSING ALTERA CORPORATION
Unable to Check Out License
If you have a floating license and the mgcld license daemon is expired or not
compatible with the required ModelSim-Altera mgcld daemon, you will
receive a fatal error message that the license cannot be checked out.
To resolve this problem, you must use the mgcld daemon in the <ModelSim-
Altera installation directory>\win32aloem instead of the mgcld daemon
that is included with the Quartus II software version in the <Quartus II
installation directory>\win directory. If you require the mgcld daemon for
a different operating system, download the appropriate file at the License
Daemon Downloads on the Altera website.
You might encounter a similar error if the lmgrd and lmutil daemon
versions are not compatible with the ModelSim-Altera software. You can
find the compatible daemons in the <ModelSim-Altera installation
directory>\win32aloem directory. However, for the Quartus II software,
you must use the daemons in the <Quartus II installation directory>\win
directory.
ModelSim-Altera Edition Software on a
PC for Versions Prior to 5.5e
The ModelSim-Altera Edition software for versions prior to 5.5e licensing
requires additional steps for a PC license, which are not required for UNIX
workstations, or versions 5.5e and later, in which case the
LM_LICENSE_FILE environment variable setting is sufficient.
In the applicable software versions, the PCLS utility runs during the
software installation and allows you to specify the license file for the
ModelSim software. If the license file was not properly set up when the
software was first installed, run the PCLS utility after installation to correctly
specify the license file. To run the PCLS utility after software installation, run
the setup.exe file located in the <ModelSim installation directory>\
drivers\pcls directory.

ModelSim-Altera Editions
ModelSim-Altera Edition software (version 6.4a and later) corresponding to
the Quartus II software versions 9.0 and later supports both VHDL and Verilog
HDL simulation. However, the OEM software tool does not support mixed-
language simulation.
