Re: Agilex 5 – Critical HSSI Error in JESD204B Example Design
Could you try in the latest Quartus Pro version 26.1 (released publicly last week on 7th Apr) and see if the issue still persists? If the issue persists, please share the QAR file (In Quartus, go to Project → Archive Project) as a .zip file. Unfortunately, the forum does not support direct .qar file attachments. Regards, Richard Tan6Views0likes0CommentsRe: CORDIC ATan2 Failed to Generate
I tested this using Quartus Prime Pro 25.3.1 on an Agilex® 5 device, running on a Linux system, and did not encounter any issues on my side. Could you please let me know which device and operating system you are using? Try to upgrade to Quartus Pro 25.3.1 (this version only support Agilex devices) or the latest version 26.1, and see if the issue persists. Regards, Richard Tan5Views0likes0CommentsRe: Issues with downloading
Oh no, you need to use the file name for the installer. Example: qinst-standard-windows-24.1std-1077.exe In your case, it should be: qinst-standard-windows-24.1std-1077.exe -sp"--cacert C:\cacert\caert.pem" You get the filename when you download it. Alternatively, the filename is also stated in the Quartus Download Center. https://www.altera.com/downloads/fpga-development-tools/quartus-prime-standard-edition-design-software-version-24-1-windows As a reference, this is another forum thread with the same issue: https://community.altera.com/discussions/quartus-prime/unable-to-download-quartus/351334?before=MjYuMnwyLjF8aXwxMHwzOTowfGludCwzNTE2MjksMzUxNDMz&topicRepliesSort=postTimeDesc Regards, Richard Tan9Views0likes2CommentsRe: Error Modelsim-Altera for integer type ports in adder

Always verify implementations in your specific environment and consult official Altera documentation for production deployments. Introduction Licensing issues are one of the most common reasons FPGA tools fail to start. The good news is that most problems are configuration related and can be fixed quickly by following a simple, step-by-step approach. Sections 1: Start with the Error Message (Most Important!) Always look at the first licensing error message shown by the tool. This is usually the real issue. Any errors that appear later are usually caused by the first problem. Here’s are common error messages and what they usually mean: Invalid hostid → License does not match your machine ID Cannot find license file → Invalid or missing license path Unable to checkout a license → License not found, in use, or server issue 300: License version is outside the range of the contract → license file generated with blank FLEXlm error: Vendor daemon version is too old → daemon used mismatch or too old Cannot checkout uncounted license in Windows Terminal Services → Questa does not support remote desktop. Most common errors already have known fixes. Try searching the error message or key issue at: Altera Knowledge Base: https://community.altera.com/category/top/kb/knowledge-base Altera Community Forums: https://community.altera.com/category/forums For floating licenses, you can also check the FlexNet error code list: Error Code Descriptions Don’t try to fix everything at once. Fix the first error, then retry. In many cases, the rest will disappear automatically. 2: Check Your License (.dat) File Open the .dat license file using a text editor (for example, Notepad) and verify the following. i. Machine ID (NIC / HOST ID) The license is locked to a specific machine ID. Example in the license file: # Primary Machine ID-NIC ID 12AB34C56EF7 If the Host ID doesn’t match your machine ID, the license will not work. Helpful Tips 1: ----------------------------------------------------- START ----------------------------------------------------- Quartus software can automatically detect the Machine ID. To view this, go to Tools → License Setup, then check Local System Information and select one of the detected NIC IDs. ------------------------------------------------------ END ------------------------------------------------------ ii. License Type Licenses are set up differently, so confirm which type you have.Look for one of these lines: # Fixed Node License → Nodelocked license # Floating Server License → Floating license Nodelocked: Locked to one machine Floating: Served from a license server and shared Make sure you’re following the setup steps that match your license type. iii. Product License Summary Find the Product License Summary section and confirm it lists the tools/IP you’re planning to use. Examples: Quartus® Prime Software (Standard / Pro) Questa® FPGA Starter Edition (SWQUESTA) If a tool or IP is not listed here, it won’t be able to check out a license—even if the license file setup successfully. iv. License Expiration & Maintenance Licenses can look similar but behave very differently. We have: a. Perpetual License Has a Maintenance Expiration date You can use tool versions released before that date Example shown in license file: # Maintenance Expiration of 2026.06 # No license expiration date b. NonPerpetualLicense Has a hard expiration date License stops working after this date Example shown in license file: # License Expires 20Jun2026 Always doublecheck the license expiration & maintenance date before moving on. 3. Verify Environment Variables The tools use environment variables to find the license. If these are wrong, the tools may not find your license—or may use an old license file. Common environment variables: Different tools use different environment variables to locate the license. LM_LICENSE_FILE → Quartus® Prime SALT_LICENSE_SERVER → Questa* FPGA Edition Depending on the license type, they should point to: Nodelocked license: Full path to the .dat file Floating license: port@hostname Examples: LM_LICENSE_FILE=C:\licenses\license.dat LM_LICENSE_FILE=25000@licenseserver Next verify the environment variable. Open Command Prompt and run: echo %LM_LICENSE_FILE% If nothing is printed, the environment variable is either not set or the changes have not taken effect. If it is the latter, close and reopen the command prompt after making the changes. If the variable points to an incorrect location, update it accordingly. Note that outdated or incorrect environment variables are a very common source of issues. Helpful Tips 2: ----------------------------------------------------- START ----------------------------------------------------- There is a quick way to set using command line. Open Command Prompt and run: Windows: setx LM_LICENSE_FILE <path_to_license_file> Linux: setenv LM_LICENSE_FILE "<path_to_license_file>" ------------------------------------------------------ END ------------------------------------------------------ 4. Check the License Server (Floating Licenses Only) If you’re using a floating license, verify the server. On the client machine: Server hostname resolves correctly Network is working Firewall is not blocking the license port On the license server: License server process is running Vendor daemon is running Server log shows no fatal errors Licenses are available (not all checked out) If the server isn’t running properly, clients won’t be able to get licenses. 5. Scenario / Walkthrough i) A floating license setup walkthrough (Know-How: Set Up a Floating License) is available to guide you through the complete process of configuring a floating license. Know-How: Set Up a Floating License (Step-by‑Step Walkthrough) | Altera Community - 352000 ii) If you generate a license but do not receive the license email within 5 minutes, you can manually download the license file using the steps below: Log in to SSLC. Navigate to Computers and License Files. Click the Primary Computer ID. Go to the ENTITLEMENTS tab. Select the relevant license (for example, LR‑****). Click the license file link to download the license file. Example shown below: Conclusion Licensing issues are almost always setup or configuration problems. Following this guide step-by-step starting with the error message will resolve most issues. If you’re still stuck after trying all the steps, feel free to post your issue on the Altera Community Forum (https://community.altera.com/category/forums) for help. When posting, please try to include the following: i. Error Details The exact licensing error message, copied as is If there are multiple errors, include the first one shown ii. Tool Information Product name (example: Quartus/Questa) Tool version (example: Quartus Pro 25.3/ Questa Altera FPGA Edition 2025.2) Operating system (Windows or Linux, version if known) iii. License Information License type: Nodelocked (fixed)/ Floating (network) Purchased / Evaluation license If possible, a copy of the license file (.dat) iv.

#sharing #debug #altera #alldevices #license Disclaimer: This article is provided as-is for educational purposes only, without warranty of any kind. Use the information at your own risk. Always verify implementations in your specific environment and consult official Altera documentation for production deployments. Introduction This guide explains how to set up a floating license for Altera® FPGA tools. The instructions and screenshots are based mainly on the Windows* operating system, but the same concepts apply to Linux systems. Overview: What You Need Before Starting Before you begin, make sure you have the following: A valid floating license file (.dat) - For the examples below, this file will be referred to as float.dat. Access to the license server machine The license server’s hostname and NIC ID / Host ID Steps Step 1: Generate the Floating License File (SSLC) i. Log in to the Self Service Licensing Center (SSLC). ii. Select your product entitlement, for example: - Quartus Prime - Questa iii. Choose one of the following: - An existing computer with FLOAT license type - Or select + New Computer, in the Create Computer, choose FLOAT license type, and enter the license server NIC ID / Host ID 4. Generate and download the license file (.dat). Step 2: Edit License File i. Open the downloaded license file and update it based on the instructions provided in the User Guide Section 6.4.4.1: Setting Up a License File in the License Server: Altera Documentation and Resources Center Helpful Tips 1: ----------------------------------------------------- START ----------------------------------------------------- To find the license server hostname - Open a Command Prompt and run: hostname - Install only the latest license daemons. Remove all older versions, and keep only the most recent ones. Required daemons: FlexNet License Daemon for FPGA software (64‑bit) Includes: alterad (Altera daemon), lmgrd, lmtools, lmutil (These are used later in Step 3.) FlexNet License Daemon for Siemens ModelSim / Questa FPGA software (64‑bit) Includes: saltd (Siemens Advanced Licensing Toolkit Daemon) Download link: Flexlm License Daemons for FPGA Software | Altera *If you’re running a floating license server for Siemens licenses, you need to manually change the VENDOR daemon line in the license file from mgcld to saltd. It is optionally to put user-defined port numbers for the alterad and saltd daemons unless you have specific port numbers that allow firewall access. In this case, I left it empty. ------------------------------------------------------ END ------------------------------------------------------ ii. At the end of Step 2, your license should looks similar like below (Windows): Important to note: Use “” if there is space in the path. Step 3. Launching the Licensing Server The requisites to configure a new license server are: System administration (Administrator) privileges. A valid license.dat floating license file. (Linux only) To run the FLEXlm lmgrd license server manager, make sure that the /usr/tmp directory exists. There are two methods to launch the license server: a) Using the Command Line Interface (CLI) i) Open a Command Prompt (Windows) or Terminal (Linux). ii) Change to the directory where the lmgrd executable is located. iii) Start the license server by running command: lmgrd -c <license.dat> Example: lmgrd -c float.dat This command starts the license server using the specified license file. You will see a few windows pop up showing that the daemons are running. Helpful Tips 2: ----------------------------------------------------- START -----------------------------------------------------To make things easier - skipping the a) ii) step, you can add the path directory that contains lmgrd to your system’s Path environment variable. Once it’s added, you can run the lmgrd command directly from any directory in the Command Prompt. ------------------------------------------------------ END ------------------------------------------------------ iv) To verify the license status. Run: lmutil lmstat –c <license.dat> Example: lmutil lmstat –c float.dat How to Read the above info: Line Note License server status: 1234@<hostname> This contains the license server name needed for the license environment variable setup. It is displayed in the form of <port number>@<hostname> License file(s) on <hostname>: <License Path> : This showed which license file is being used. This is where you make sure the license file you are using is correct. <Hostname>: license server UP (MASTER) v11.19.6 This mean the license server is up successfully. Vendor daemon status (on <hostname>): This showed the vendor daemon status and the daemon version you are using. Make sure the version used is the latest version available. v) Stop the license server: lmutil lmdown -c <license.dat> Example: lmutil lmdown –c float.dat Helpful Tips 3: ----------------------------------------------------- START ----------------------------------------------------- The above command just display the overall status of the license. You can add -a option in the command to report out the verbose list of available licenses and its total numbers of seat, example: lmutil lmstat –a –c <license.dat> Example: lmutil lmstat –a –c float.dat To check a specific feature: lmutil lmstat –c <license.dat> -f <feature name> Example to check the Questa Altera FPGA Edition license: lmutil lmstat –c float.dat -f intelqsim View command options: lmutil lmstat -help ------------------------------------------------------ END ------------------------------------------------------ b) Using the Graphic User Interface (GUI) 1. Right‑click lmtools and select Run as Administrator. 2. In the Service / License File tab, select Configuration Using Services. 3. Switch to the Config Services tab and configure the required fields below: 4. Click Save Service. 5. Go to the Start / Stop / Reread tab and click Start Server to launch the service. 6. Click Stop Server to shut it down. Helpful Tips 4: ----------------------------------------------------- START ----------------------------------------------------- The GUI performs the same actions as the command line, but is easier to visualize. For debugging, the CLI provides more detailed output. If something fails, always check: - Server Status - Debug Log Diagnose license or feature issues using CLI: - lmutil lmdiag -c <license.dat> <feature_name> If using GUI, you can run diagnostics from the Server Diags tab. ------------------------------------------------------ END ------------------------------------------------------ Conclusion This guide provides a complete walkthrough for setting up a floating license server for Altera FPGA tools. Following these steps should help ensure a reliable and functional license environment.47Views0likes0Comments
