Empty License for Questa Starter Edition
I've requested a license from the self-serving center and implemented it according to the manual. However, when I tried to simulate my circuit in Quartus through Questa, I got an error saying that the license could not be checked out. When I checked the license file, all of the lines of code were just comments. After searching around old posts, the issue seems to stem from Intel's license generator itself. I need to use Questa for my research, so can I request a license directly?Solved1KViews0likes6CommentsWhat to do if I recharged a wrong number?

Steps to Get a Refund:SolvedIs Quartus Prime Pro 22.4 Compatible with Stratix 10 NX Series Device 1SN21CEU2F55E2VG?
Hello everyone, I'm wondering if Quartus 22.4 supports the Stratix 10 NX series devices. My chip model is 1SN21CEU2F55E2VG. I've installed Quartus 22.4 along with the Stratix 10 device library, but I can't seem to find any options related to this chip. Has anyone else encountered this issue or knows if this version supports the Stratix 10 NX series? Any help or guidance would be greatly appreciated! Thank you!39Views0likes3CommentsWhat if I did wrong recharge in Jio?

I just tried to generate a new Questa Starter license through the Self Licensing Center but the license file I got is corrupted (it does not contain the "increment" statement and hence it actually does not contain a license). I tried generating the license several times but I always got such a corrputed file. You can find the corrupted file attached. The problems seems to apply for Questa Starter only. Other free features (e.g. Agilex-5 support) could be licensed correctly (contained an increment statement). How can I generate a Questa Starter License? I am maintaining the Open Logic FPGA Standard Library - also officially supporting Altera. So I'd hope there should be some mutual interest of fixing the issue.22Views0likes3CommentsCan I get a refund if I accidentally recharged the wrong number?

Hi, I am aware that Cyclone I is a legacy device, but we are maintaining a long-life product and would appreciate any insights from experienced engineers. [ Environment and System Configuration ] I am maintaining a legacy system developed 20 years ago. I am facing inexplicable configuration and boot issues that depend on the programming environment (PC/location) and the sequence of file versions written. FPGA: Cyclone EP1C3T100C8 Configuration Device: EPCS4SI8 Software: Quartus II 9.1sp2 Web Edition OS: Windows 7 Professional SP1 Download Cable: Terasic USB Blaster Setup Locations: A) Design Office (Me): 2 boards (with JTAG access), PC "A" B) Factory: Multiple boards (AS mode only, no JTAG), PC "B" [ Description of Phenomena ] Phenomenon 1: Spontaneous Mode Change (Factory / 2-year-old board) In Dec 2025, a board worked correctly. In March 2026, it behaved as if it were in a different operation mode. Details: The mode is hard-wired within the internal logic and should not transition. Action: Re-writing the same POF file restored normal operation. Note: This happened within only a few months of storage. Phenomenon 2: Failure to Transition from Initial State (Office / 10-year-old board) A JTAG-enabled board was stored for one year. Now, it fails to function even with known-good files. Details: Even writing the original SOF that worked in Feb 2025, the FPGA stays in its initial state and fails to perform state transitions. Quartus reports "Success," but the hardware logic does not execute. Phenomenon 3: Sequence-Dependent Success (Factory / New 2026 boards) When writing a Dec 2025 POF to five new boards: Behavior A (3 boards): Initially stayed in the initial state. However, after writing an older Feb 2025 POF, they started working. Over-writing them with the Dec 2025 POF then resulted in success. Behavior B (2 boards): Worked perfectly from the first attempt. Why would a specific version history be required for some boards to work? Phenomenon 4: Lack of Compatibility (Office vs. Factory) A POF verified to work when written by Factory PC (B) does not work when written by Office PC (A). Details: When written by PC A, the board stays in the initial state and fails to transition, identical to Phenomenon 2. [ Discussion and Questions ] Incomplete Initialization: Is it possible for the configuration to reach "Done" while internal registers fail to initialize correctly due to power supply slew rates or noise? Silent Data Corruption: Are there known issues with Quartus 9.1sp2 and Terasic Blasters where bit errors occur during programming without being caught by the verification process? EPCS4 Residual State: Why would writing an older version "prime" the board to accept a newer version? Could this be related to EPCS sector erase issues? Since these are legacy devices, any insights would be greatly appreciated. Regards, HKana175Views0likes0CommentsQuartus/Signaltap complains about wrong version
Hello, we are using Quartus prime V24.1.0 for a rather large project. We have various signaltap files stored within git for analysis. Now, from time to time, it happens that quartus throws the following warning/assertion. Obviously, this assertion can be suppressedwith ENABLE_VHDL_STATIC_ASSERTIONS OFF, and everything is working. However this is no soulution as we want to have ENABLE_VHDL_STATIC_ASSERTIONS ON Error (22148): VHDL error at sld_ela_control.vhd(1263): Failure: "The design file sld_ela_control.vhd is released with Q uartus Prime software Version 24.1.0. It is not compatible with the parent entity. If you generated the parent entity us ing the Signal Tap megawizard, then you must update the parent entity using the megawizard in the current release.": exi ting elaboration File: c:/intelfpga_pro/24.1/quartus/libraries/megafunctions/sld_ela_control.vhd Line: 1263 If I remove the signaltap(file) entirely, and readd it, everything works. However, this is very annoying and time consuming. Q1. Why is this assertion triggered in the first place? We do not use any other versions. Q2. How do I "update the parent entity using the megawizard"? I'm unable to find an "update" option. To me deleting signaltap and re-creating it is not an update....

In a world where technological complexity is rising, standards are evolving, and differentiation is critical, customers need partners who can move fast, stay focused, and innovate without compromise. At Altera™, operating as an independent pure play FPGA solutions provider is more than a corporate structure. It’s a strategic advantage. For more than four decades, Altera has been at the forefront of FPGA innovation, helping customers push the boundaries of what’s possible across the most demanding applications. With our recent operational independence and singular focus on pioneering FPGA innovations, we are uniquely positioned to deliver FPGA solutions that enable customers to differentiate, innovate, and grow in rapidly changing markets. Why Demand for FPGAs is Accelerating The FPGA industry is entering a period of strong, sustained growth, driven by powerful forces across cloud, networking, and edge applications. As enterprises race to process and monetize exploding volumes of data, FPGAs have become a critical enabling technology, uniquely suited for workloads where flexibility, re-programmability, and real-time performance matter most. Over the next five years, the market is expected to grow at roughly 10% CAGR, expanding from an estimated ~$7B in 2025 to more than $13B by 2030¹. Demand is accelerating across data center and networking, telecom, aerospace and government, industrial automation, robotics, medical, and beyond. Growth is being driven by AI infrastructure modernization, 5G-Advanced and early 6G deployments, and the rise of physical AI and real-time, low-latency edge computing. At the same time, escalating development costs for ASIC and ASSPs, longer development cycles, and the need for post-deployment flexibility are pushing more customers toward programmable solutions that reduce risk while maintaining performance and differentiation. Altera is uniquely positioned to help drive this next phase of growth. As the largest independent, pure-play FPGA solutions provider, our agility and focus allow us to move faster, invest deeply in a thriving ecosystem, and deliver differentiated, end-to-end solutions backed by strong customer support. By partnering closely with customers, we enable them to seize opportunities across AI, cloud, networking, and edge applications.
