Guidelines & Information on Questa-Intel FPGA Edition Software



To the Intel Community, 


As you may aware, Modelsim-Intel FPGA Edition will be replaced by Questa-Intel FPGA Edition Software (including Starter Edition) starting from Intel Quartus Pro Edition 21.3 and Intel Quartus Standard Edition 21.1 onward. 


Does the Questa-Intel FPGA *Starter Edition Software requires a license?

One thing to take note that Questa-Intel FPGA *Starter Edition Software requires a license (free cost) whereas Modelsim-Intel FPGA *Starter Edition does not require a license. To get the license, we will need to generate the license from Intel® FPGA Self Service Licensing Center (SSLC). The license is free for one-year and perpetual. Once the license expires, regenerate the license to continue using the latest Questa-Intel FPGA *Starter Edition Software.


Why does the SSLC GUI changed? 

For those whom have used SSLC before, you may notice that the SSLC has changed to a new GUI recently. If you have never access the SSLC previously, the above URL webpage may ask you to register an account in Intel FPGA SSLC. Click Next: Verify and wait for an email confirmation. Once you receive the email confirmation, do log out your Intel account and login again to generate the license required in SSLC.  


If you don't have access to the Intel® FPGA Self Service Licensing Center (SSLC), register to get an account by clicking the URL here - Register for Intel® FPGA Self Service Licensing Center (SSLC) 


How to generate license in the SSLC? 

In the SSLC, select the Questa*-Intel® FPGA Starter Edition SW-QUESTA and fill in the number of seats required. Once you have read the license terms of use, click the "I have read and agree to the terms of use of this license as listed below".

Proceed to click Get License.  A window will pop out to ask which computer should the license assigned to.

To check the computers list, you may use the new License Assistant available at the . Choose Regenerate license by Primary ComputerView all computers and select to view the computers list. 
Or in the Computers and License Files tab, you can check your current active computer list.

How to set up license for the Questa-Intel FPGA *Starter Edition Software?

For Windows: 

1. Get a license.dat file first
2. Go to "My PC", right click properties
3. Click Advanced System Setting.
4. In the "Advanced" tab, click environment variable. In the "System Variable", create a New variable with name= LM_LICENSE_FILE, set value=<license.dat path name>

5. Click OK and restart the Questa software. 


Alternatively, a shortcut you can use is - open command prompt and key in below command to set up the LM_LICENSE_FILE environment:

setx LM_LICENSE_FILE <license.dat path name>

For Linux, this can be done in the shell using the using the setenv or export command depending on the shell.

export LM_LICENSE_FILE=<path_to_license_file>

setenv LM_LICENSE_FILE "path_to_license_file"

Hi, there seems to be a bug on your website when trying to generate a Questa license in the SSLC.

When pressing the Create a New Computer button the following error message pops up:


Edit: This bug seems to be present when running Google Chrome 95.0.4638.69 . It does seem to work in Microsoft Edge.

Can you share how to create a floating license for multiple desktops?


I am trying to use Questa starter edition on about 50 desktops and can't seem to get it to work.
I created a license server. Set the NIC ID of the license server and put that in SCLC and got a license.dat file. But the it is not working.


Thanks for any help.

Hi @nonenonenone 


If you have a new question, I recommend to file a new thread for support as this thread has been transition to the community and you may not get the support from the Intel. 

Anyhow, since I noticed your questions, I will be help to answer. 

You will need to set the License Type to 'Float' if you want to create a floating license. 

You can check this in the Computers and License Files > All Computers
