S10 hps fpga2sdram bridge low speed
Hello, i have some problems I have a project with stratix 10 with hps I need to use ddr4 with hps, so I enabled 3 fpga2sdram bridges with 128 bit width Via u-boot smc configured and enabled them, but measured speed is not enough. When I use onle one bridge my speed is approximately 32 gbit/s (bridge and master frequency 350 MHz) But when I use all 3 bridges it becomes 20 gbit/s I use avmm bridge to connect to axi fpga2sdram bridge with 128 bits width, max pending writes 16, max burst size 128, use only write to bridge ECC in emif (hmc) is disabled I tried to use QoS for bridges, set them to bypass P.S. If i use the same board with firmware without hps, i get 130 gbit/s (with disabled hps) Quartus Pro 21.4 Any help would be useful!20Views0likes2CommentsConnecting Intel Agilex FPGA to DE1-SoC via Hub
Hello, I have an Intel Agilex FPGA with QSFP-DD 10 GbE PHY, a DE1-SoC board with 1 GbE PHY, and an Ethernet Hub 1 GbE. I want to connect the Agilex to the DE1-SoC through this hub. I understand the DE1-SoC only supports 1 GbE while the Agilex PHY is capable of 10 GbE. I would like to know the best way to communicate between these boards. Is it possible to configure the Agilex Ethernet IP and PHY to 1 GbE so it can communicate directly through the hub without a physical adapter? If not, would a media converter or adapter be needed to downspeed from 10 GbE to 1 GbE? Are there any recommended best practices for connecting an Agilex to a slower device like the DE1-SoC via Ethernet? Any guidance or experience would be greatly appreciated. Thank you!14Views0likes2CommentsQuartus 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.43Views0likes3CommentsNIOS SDK SBOM/FOSS info
Hi, Regarding CRA, more and more customers are approaching us with inquiries about FOSS (Free/Libre Open Source Software). Do we have FOSS information or a SBOM (Software Bill of Materials) for the NIOS SDK that we can share with customers? Br, Korbinian105Views0likes5CommentsAshling IDE scripted project creation
On Windows, is there a way to script the Ashling IDE project creation (or import an existing project)? I'm trying to clean my project down to the bare minimum for CM/repo purposes (deleting .metadata), and then have an automated way to recreate the project up to the point I can open Ashling RiscFree IDE, point to my (newly recreated) workspace, and then the project is already imported and ready to build, with all my previous settings (include paths, optimizations). Right now, the only way I can get this to work is if I manually click File -> Import and go through that dialog to import my sources from the repo. I need a hands-off way to do this. I looked at the Ashling RiscFree IDE manual, but couldn't find anything.99Views0likes4CommentsOnce 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.47Views0likes5CommentsWhen 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.34Views0likes7CommentsAgilex 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?23Views0likes0CommentsUSB-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!185Views1like8CommentsWarning 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?85Views0likes10Comments
