SETTING UP THE LICENSE FILE

ALTERA CORPORATION ALTERA SOFTWARE INSTALLATION AND LICENSING ■ 52

The ModelSim-Altera Edition software supports licenses using the Mentor

Graphics license daemon mgcld. You can find the mgcld daemon in the

following directories:

Windows: <ModelSim-Altera system directory>\win32aloem\

Linux: <ModelSim-Altera installation directory>/linuxaloem

<Quartus II system directory>/linux/linuxaloem (when installed

using the Altera Complete Design Suite for Linux DVD)

Before starting the ModelSim-Altera software, you must set the

LM_LICENSE_FILE environment variable to the location and file name of

the ModelSim-Altera license file. For example, LM_LICENSE_FILE

(<ModelSim-Altera installation directory>/licenses/eda/license.dat) or

with the <port>@<host> notation (1900@set), Where <port> is the license port

number and <hostname> is the server’s host name as defined in the

“Modifying the Network License File” on page 49.

To set the LM_LICENSE_FILE environment variable to the location and file

name of the ModelSim-Altera license file for Windows or Linux, refer to

“Specifying the License File Using the LM_LICENSE_FILE Environment

Variable” on page 43.

The ModelSim-Altera Edition software license expires 15 months after the

date of purchase, at which point you can no longer use the software. You

must obtain an updated Quartus II software subscription license file from

the Self Service Licensing Center of the Altera website at www.altera.com/

licensing every 15 months to renew your license for the specific ModelSim-

Altera Edition software version that you purchase. You can use only the

version of ModelSim-Altera Edition software that you purchase with the

updated license.

After receiving the updated Quartus II software license file, you must

perform the procedure described earlier in this section to specify the license

for the ModelSim-Altera Edition software.
