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.
jtagserver.exe causing BSOD together with ftdi driver
Dear developers in the same shoe like me, I am facing a strange issue, and would like to ask others whether they have similar problem: Quartus Prime Pro 25.3.0 was installed first and in use with USB Blaster III (evalkit) After some time (probably windows pulled some newer driver components) each time when I plugged in the evalboard it was crashing the system. With WinDBG analyzing the minidump it turned out the responsible was jtagserver.exe calling some unknown function in ftdibus.sys "PROCESS_NAME: jtagserver.exe SYMBOL_NAME: ftdibus+f4d4 MODULE_NAME: ftdibus IMAGE_NAME: ftdibus.sys STACK_COMMAND: .cxr; .ecxr ; kb BUCKET_ID_FUNC_OFFSET: f4d4 FAILURE_BUCKET_ID: 0x139_a_GUARD_ICALL_CHECK_FAILURE_ftdibus!unknown_function OSPLATFORM_TYPE: x64 OSNAME: Windows 10 --> this is windows 11 FAILURE_ID_HASH: {3a7c8e82-5c61-9acf-ceb5-61656fa0b04c}" And here comes the strange part: Reinstalling the driver with dp_inst.exe from Quartus directory helped until next restart or at least for 1-2 hours. Then power cycling evalboard caused a crash again. When I fresh reinstalled driver and plugged in again the evalboard again everything was fine. When I updated to the latest quartus, the driver package in it was causing crash again. And I mean here reinstalling driver from the 25.3.1 quartus version did not change a thing. Anybody facing similar issue: I recommend installing Windows SDK and use WinDBG there for crashdump analysis to confirm this. I am looking forward for any feedback or stable solution idea. Kind regards, PeterAgilex3 - unknown IDCODE
Hi everyone We are bringing up an Agilex3 A3CZ100BB18A based board where IDCODE is unknown for the Quartus Programmer. Currently the attached NOR flash is empty. This would be the first time configuration. The labels/texts on the chip seems right and correct and the same part we are trying to use. Quartus Programmer has proper access to the JTAG chain, but the IDCODE contains some 0xF nibbles jtagconfig.exe --debug (JTAG Server Version 25.3.0 Build 109 09/24/2025 SC Pro Edition) F36FF0DD (IR=10) Captured DR after reset = (F36FF0DD) [32] Captured IR after reset = (001) [10] Captured Bypass after reset = (0) [1] Captured Bypass chain = (0) [1] JTAG clock speed 1 MHz IDCODE should be 0x4365B0DD As you can see there is only minor difference, only some sub ID’s are wrong. F36FF0DD 4365B0DD I need ideas what could have gone possibly wrong as in documentation I did not find any explanation to this symptom. The JTAG interface seems electrically right. Testing the IDCODE 1000x in JTAG chain debugger of Quartus gives back consistently this very same IDCODE at any startup. Thank you for your help in advance! Kind regards, Peter
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.

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?
Correct way to use mSGDMA with a NIOSV/m processor on a MAX10 FPGA
Greetings all ALTERA Experts, Can somebody please provide some guidance (e.g. links to example designs and App notes etc.) showing how to implement an mSGDMA based system using a NIOSV/m processor on a MAX10 FPGA? The first problem is where to find the best and most up to date Documentation and any example designs actually using the mSGDMA. With clear descriptions of how the data and control flow works, hopefully describing how descriptors are created and then used by the mSGDMA IP cores. Another area of concern is how to wire up mSGDMA IP cores correctly in a Qsys platform (to both data and descriptor memory etc.), and with both the prefetcher and burst mode enabled. I want to use one mSGDMA with an AVALON MM -> AVALON ST flow and a second for AVALON ST -> AVALON MM Flow. Then the next area of concern is how to write a HAL based driver with the NIOSV/m processor to interact with mSGDMA IOP cores. Thanks for any help, Dr Barry H
University Program IP for NiosV
There seems to be no way to post to the University Program forum and this looks the next best place. Now that Altera is back in command, will the University Program IP blocks be converted to the NiosV platform and when. We are currently trapped on 18.1 due to a dependence (they make great learning tools) on this IP.
Available replacement for the discontinued P/N: MK-A5E065BB32AES1 ?
Hello, PDN: https://www.mouser.com/PCN/Intel_Corporation_PDN2513.pdf?srsltid=AfmBOoqEg4CcKdQVpDMH8g2nQDlihxYoQoJwu3Bcg91PBuKx__G1W-Mf is suggesting P/N: MK-A5E065BB32AEA (Future) as replacement for the already discontinued P/N: MK-A5E065BB32AES1 A customer is desperately searching for this old or the new board, or an alternative that would be immediately available for an important project. His previous order was not considered any more, unfortunately. Can you possibly help to get hold of one of these boards, or would you know a reseller who might still have stock? Thank you very much Best regards Adnan (ref: Q1CDFE8)
