Quartus Prime 25.1 installation issue
Hello to the community. I had some problems while installing Quartus Prime. Though in the end I finally succeeded, maybe someone will point out what I've done wrong. Here are the steps: I started installation by executing the setup.bat command file. Left the configuration all default as well as the installation directory. The software successfully unpacked the files and started installing the help component. After a while it reported that it was done by the "Installation Completed" message and full progress bar. I waited for a while and then forced this window to close. It displayed some error message and quit. No further progress was observed after some time, so I killed that process too. After that I played a little with installation directories, turning on and off the antivirus, but nothing helped. In the end I came up with the following solution: Again, execute the setup.bat. Disable help installation. Wait until come other component reports it's done and do not responding. Kill that process and see some error window. Wait until installation is done. Install the help. I'm attaching a few screenshots depicting this behavior for the Ashling RiscFree component below. Though in the end I did obtain the software, it is still quite annoying and time-consuming. Maybe there is some tweak to make it smooth? I'm using Windows 10 version 10.0.19045.6466. Thanks in advance.Once again about CTRL+L
Hello. Consider this message as mere feedback. I moved from Quartus 20.1 to 25.1 and discovered that now what Ctrl+L does depends on the focus: it deletes a line if in the text editor and starts the compilation in other cases. That's quite inconvenient, if you ask me. And there was already a thread dedicated to this peculiarity. From my standpoint, the keyboard shortcut must do one and only one thing. :-) Maybe developers will take that into account for that in the future. Also, if there is a possibility to fine-tune shortcuts — point me in that direction. I failed to find that.
When you double click on a word, the other instances do not highlight due to the Find Box being open
When I am using Quartus and I happen to have the Find Box open and nothing is in it and I double click on a word in a file, the other instances will not highlight due to the fact that I have the Find Box open. You must close the Find Box before the other instances of a word will highlight again. Specs: OS = Windows Enterprise 11 Software = Quartus Prime Version 25.3.0 Build 109 09/24/2025 SC Pro Edition Patches Installed = 0.27 Steps to recreate 1. Open Quartus program 2. Open a file (HDL or Verilog, doesn’t matter) 3. Left double click on a word within the file and observe how other instances are highlighted 4. Open the Find Box (Ctrl+F) 5. Remove any word that is in the Find Box 6. Left double click on a word within the file expecting other instances to be highlighted 7. Observe that they are not highlighted due to the fact that the Find Box is still open 8. Close the Find Box 9. Left double click on a word within the file and observe how other instances are highlighted again now that the Find Box is closed This is a bug with the functionality of the Find Box.
Agilex 7 boot from config flash over JTAG
Hello. I'm trying to do remote programming/rebooting of an FPGA's flash config. After I've programmed the flash chip via the standard Quartus Programming, does the FPGA automatically load and run this bitstream (truly reading from the flash chip)? Or is there a "Boot from Configuration Memory Device" JTAG function I can induce?USB-BlasterII mounts as "USB-Blaster variant"
Hello! My company uses the USB-BlasterII pods with Quartus. Many times, when the Blaster is plugged in, it is detected by Quartus as "USB-Blaster variant" instead of "USB-BlasterII". When this happens, the JTAG clock frequency is not settable, and the pod will not operate correctly. The problem occurs equally with Quartus Prime 16.1 and Quartus Standard 24.1. I have not tried other versions of Quartus. This appears to be the same root issue that AdamLevine experienced in a previous Altera forum post: USB Blaster II | Altera Community. To answer the questions he was asked, Yes, we experience this issue on all the PCs we have tried the USB-BlasterII on. My company is running Windows 11. We tried numerous boards, but similar to Adam, the problem occurs whether a board is connected to the Blaster or not. The issue appears to be with the driver for the Blaster and how it is detected when it is connected to the PC. This problem has been occurring more lately than it used to, but we have had significant failure rates with this for the past two years almost. I know our JTAG pin connections are correct because the USB-BlasterII works perfectly IF AND ONLY IF it is detected with the correct device name but cannot work at all if it shows up with the wrong name in Quartus. Our conclusion is that the drivers for the USB-BlasterII have a problem. I suspect that the driver caches the Blaster devices that have been connected and encounters an error if the cache is not cleared by ejecting all the Blaster devices. Just a guess. Has anyone found the issues with the drivers? Is anyone from Intel available to look into this behavior? If not, would Intel supply my corporation with the driver source code so our engineers can fix it? Thanks!
Warning at Standard 25.1 by Arria 10
Hi all. recent Queatus Prime Pro 25.3.1 drops Arria 10 support. (no Arria 10 support files in individual download page) But latest Standard 25.1 warns at compile Arria 10 project, by these message Info (24153): Support for Arria 10 devices is deprecated in the Quartus Prime Standard Edition software. For new Arria 10 designs, use the Quartus Prime Pro Edition software. For existing Arria 10 designs, continue to use the Quartus Prime Standard Edition software. Is this due to the difference in release dates between 25.3.1 and 25.1? Will we no longer see this warning when Standard 25.3 is released in the near future?
error in JTAG server (error code 35) and autodetect (unable to scan device chain) Quartus 18.1
Hello fellow members, I have a Max10 FPGA Evaluation Kit board (10M08SAE144C8G) which i want to flash via JTAG. For this, i have installed Quartus Prime (18.1 version) and have USB Blaster 2 as an interface. After connecting the hardware, the LEDs on the board are stable. When i execute autodetect on the programmer , i get a dialog box stating "unable to scan device chain . Hardware is not connected"(screenshot attached). In the hardware setup , i coulkd see the usb blaster variant is added but still this error occurs. Similary when i try to run the .pof file , the diagnosis show "unexpected error in JTAG server -- error code 35" (screenshot attached). I checked the driver and it seems the USB blaster driver is also updated. On the command prompt, it shows 1) USB-Blaster variant [USB-1] Unable to lock chain - Hardware not attached Has someone encountered this issue before. Any help or suggestion would be highly appreciated. The screenshots can be seen in the attachments. Thanks. Best Regards, Ali
Quartus Dark Theme on Linux - Solution
I have a solution for setting up a dark theme for Quartus Prime 25 on Linux (Mint) and setup a Github repo. The program modifies the stylesheet using a Rust program. https://github.com/saturn77/quartus-dark-linux This repo allows running Altera Quartus on Linux with a dark theme, providing a modern look while being easy on the eyes for Linux users. There are some dark stylesheets for Windows, but those simply will not work on Linux. Quartus's argument parser intercepts -stylesheet before Qt can process it on Linux. This project uses a small Rust LD_PRELOAD library to hook QApplication::exec() and inject the stylesheet directly via Qt's setStyleSheet() API. Tested with Quartus Prime Pro 25.3.1 (Qt 6.5.7) on Linux Mint 22.3 Cinnamon.
Quartus Eda_Writer keeps crashing
Quartus Prime v25 keeps crashing at the eda_writer step during the flow on Windows 11. I have tried different Quartus versions (II v13.1, Prime Lite v25, Prime Standard v25). All of them crashed at this step multiple times. Is this an issue with the design that I am trying to implement? I searched for this error on Google and I found a message that said it was a bug that was fixed in version 21.1. Strange that its still occuring now in v25 standard.
