Quartus 20.1 and ModelSim 20.1? - Quartus 20.1 and ModelSim 20.1?
Hello Support Q1: I am currently teaching Digital Logic Design 2 with Verilog and VHDL. I requested DE10-Lite donations from Intel. I believe the transition from Intel back to Altera FPGA may have been delayed. My concern is that I am unable to complete the form. The fields 'Course' and 'Quality' are blank. Please advise when you can. Image of request for Quartus and or new versions of ModelSIM? <attache> Terasic mentioned requesting the DE10-Lite board, we can have the school purchase it at our academic pricing, but we will ask for donations for the Spring semester. Q2: I initially had my students download QL 22.1 and MS 20.1; they worked during the summer as I prepped. When I ran the program, I encountered errors and was advised to downgrade to QL 20.1 and MS 20.1. This resulted in some success programming the device in QL; for MS, the simulations were not successful, and I could not verify the timing. "Which versions should I use that produce fewer errors? We will use the DE10-Lite and another board, not sure. It has been several frustrating sessions, and it has been a bit confusing. We are currently using Quartus Prime 20.1 and ModelSim 20.1, Intel FPGA Starter Edition 2020.1. Q3: Regarding ModelSim, is there a reference user guide? As we move forward, please advise, and thank you for your time. Image of the request for donations:

It is not advised to reply to the email altera-community@us.khoros-mail.com. I believe this is a system-generated address that only sends you notifications when there is a reply or an update to the specific topic you are following. If you need to respond, please post directly in the topic thread on the forum. Regarding the issue with configuring the ADC or PLL IP in Quartus Lite 25.1, if you need further help on debugging, please kindly create a new topic in the forum so the community and Altera support team can better assist you. For Questa, Altera recommends downloading the version that is bundled with your Quartus installation to ensure compatibility. You may choose to use a newer version, but please do so at your own risk.

Thanks Richard last semester students struggled with QL 25.1 the ADC was challnege one of student oyur staff and confirmed the latest version has issue configuring th IP for ADC and PLL? he was advise to download 23.xx so that did work. The question: do we need to get a Questa MS for this version? as I Questa license working fine. Please advise thanks Jeff email below bounced: Email to Richard bounced?

Half of the class installed 23.x, and it appeared to work. Please advise: since we have licenses for Questa-Model Sim, do we need to apply for another license, or will the one we have be sufficient? Advise when you can, and thanks for your time. Jeff Canion Also, we requested (10) boards through the university program, the DE-10 (standard) We purchased the DE10-Lite and (2) appear to be damaged th others are ok

I recommend using the Quartus Installer to install the software. To verify that the tar file is correct, please check the SHA1 hash of the downloaded file and compare it with the value provided on the webpage. Regards, Richard Tan

My students are using the DE10-Lite MAX 10 device I will need to install Questa 23.1 Please confirm the latest version does not support the DE10-Lite. Thanks

Yes, the students can install it on their laptop. They will need register an Intel account in the SSLC and generate the Questa no-cost license. You may need to guide them through the license setup process using the user guide I provided. Please note: there is a typo in the document regarding the environment variable. Use SALT_LICENSE_SERVER instead of SALT_LICENSE_FILE. I believe you’re planning to install Quartus as well. Please ensure that your system meets the hardware and software requirements as stated in the user guide. https://www.intel.com/content/www/us/en/docs/programmable/683472/25-3/system-requirements-and-prerequisite.html Regards, Richard Tan

Thanks, Richard. I will have my IT dept install on the Lqb Workstations. Can my students install on their laptops? Yes, and I will install on my personal laptops and work laptops. I watched a few videos, and its interface looks the same as ModelSim's, but it's faster and better.

Yes, as indicated in the KDB, the Questa Starter Edition software requires a no-cost license, which is different from the ModelSim Starter Edition that does not require a license. The license is valid for one year and must be renewed annually through the Self Service Licensing Center (SSLC). To check whether the license is generated correctly, you can open the .dat license file and look for the license feature "intelqsimstarter". KDB: https://www.intel.com/content/www/us/en/support/programmable/articles/000088418.html To learn how to generate and set up the license file, please refer to the document below: https://www.intel.com/content/www/us/en/docs/programmable/683472/25-3/and-software-license.html To learn more about the Questa tool and its benefits, you may refer to the webpage https://www.altera.com/products/development-tools/quartus-prime/questa For installation, ensure that the operating system is supported for Questa, as listed on the following webpage: https://www.altera.com/design/guidance/software/os-support#editorialTableBlade-23 Additionally, the installation of Questa* Altera® FPGA Edition installs the Microsoft Visual C++ 2019 Redistributable Packages automatically. https://www.intel.com/content/www/us/en/docs/programmable/683472/25-3/software-requirements-24995.html Regards, Richard Tan

Thanks, Richard. As I will be teaching this same class next semester, we will try Questa Standard (free). Does it require a license? Our IT department has not yet resolved the installation issue; Windows rejects the expired certificate. There was a workaround for the BIOS. But still left some workstations not installed correctly? Our last resort was to install ModelSim on the laptops, but it had issues. 1. Questa

Hi, additional: User guides can be found in the ModelSim or Questa docs/pdf folder. I see that there may be a reason to stay with Quartus/ModelSimASE 20.1 for your courses to avoid license installation issues. Regards Frank

Hi jcanion-csn , 1. For any inquiries related to the Altera University Program, please contact university@altera.com directly. The forum is intended for technical support only. https://www.altera.com/newsroom/news/press-release/altera-university-launch 2. It is recommended to use the simulator tool version bundled with the corresponding Quartus version (e.g., Quartus 20.1 with ModelSim 20.1). Did Terasic specify any recommended Quartus version for their board? MAX 10 devices appear to still be supported in the latest Quartus Lite/Standard version 24.1. Altera always recommends using the latest supported Quartus/Questa version, ensuring that the operating system used is also supported.
