Re: Signal Tap - *** Fatal Error: Segment Violation
Yes, having the report will help the developer debug the issue. Usually, being able to duplicate the issue makes it easier to narrow down the root cause. If the issue cannot be duplicated, the developer will need the report to see what can be done. In terms of severity, it depends: if this internal error does not occur very often and does not block development or production, I would consider the severity to be low for now. If it does block development or production, then the severity would be high. Don't worry, this is the right forum to report bugs. Thanks, Kenny1View0likes0CommentsRe: When you double click on a word, the other instances do not highlight due to the Find Box being open
I make a comparison between this case and the previous one: Table 1: https://community.altera.com/discussions/quartus-prime/highlight-similar-instances-of-a-selected-word-fails-when-scrolling/337284/replies/350951 Aspect Your Original Issue (selection jump & mass deletion risk) Find Box state Closed with non‑empty search term left in it Trigger After closing Find, start selecting (click‑hold‑scroll) or scroll with wheel Observed behavior Scroll re-selects previous Find term- Click‑hold‑scroll selection can jump to top (unintended large selection) → risk of mass deletion Table 2: https://community.altera.com/discussions/quartus-prime/when-you-double-click-on-a-word-the-other-instances-do-not-highlight-due-to-the-/351004 Aspect New Steps (double-click doesn’t highlight when Find is open & empty) Find Box state Open and empty Trigger Double‑click a word expecting “highlight all instances” Observed behavior Double‑clicking a word does not highlight other instances while Find box is still open- Once Find is closed, highlight‑all behavior returns. Let me know if this is incorrect, can you also send us the video for this issue? Please note that I have reported the table 1 bug to engineering to fix it. Thanks, Kenny0Views0likes0CommentsRe: Highlight similar instances of a selected word fails when scrolling
Currently, based on your video, i manage to duplicate the issue with below: When using the Quartus Prime Pro Edition text editor (VHDL/Verilog), the editor selection logic behaves incorrectly after performing a Find (Ctrl+F) operation with the search term left in the Find box when the Find dialog is closed. This results in: Unexpected re-highlighting of the previous search term when scrolling. Selection “jumping” to the top of the file during click‑hold‑scroll actions. Risk of unintentionally selecting large portions of the file and accidentally deleting user code. Possible loss of work if the user doesn't immediately notice the unintended selection. Steps to Reproduce 1. Open Quartus Prime Pro Edition 25.3 (with patch). Create a new VHDL (or Verilog) file. Add repeated occurrences of a token (e.g., event_plan). Highlight one occurrence and press Ctrl+F → Find dialog appears and all matches are highlighted. Close the Find dialog without clearing the search term. Now attempt either: Case A — Scroll after single-click: Click anywhere else in the file to place the caret. Scroll with mouse wheel → selection unexpectedly reverts to the last Find-matched word. Case B — Click-hold-scroll selection: Start a selection (e.g., click-hold at line 50). Drag or wheel-scroll downward. The selection unexpectedly jumps to the top of the file, selecting everything above. Pressing Delete removes large unintended sections of code. If anything is not covered above, can help create a new case and attach a new video? If it is already covered, you do not need to create a new thread.

We do not support DO_254, you may need to contact our partner like the Aldec for the support. https://www.aldec.com/en/solutions/do_254_compliance/fpga_level_in_target_testing We do however support functional safety, https://docs.altera.com/r/docs/683247/25.1.1/quartus-prime-pro-edition-user-guide-block-based-design/block-based-design-flows-revision-history you may check here.2Views0likes0CommentsRe: Highlight similar instances of a selected word fails when scrolling
I try the below steps and cannot find the problem, did i do anything wrong? Can you send us the video on what you did? Step-by-Step Instructions for Highlighting Issue in Quartus Prime Pro 25.3 1. Open Your File in Quartus Launch Quartus Prime Pro 25.3. Open the text file you want to edit in the built-in text editor. 2. Confirm Editor Settings Go to the text editor preferences. 3. Test Highlighting Double-click a word in your text file. All similar instances should initially highlight? 4. Scroll to Observe the Bug Scroll using your mouse wheel. Notice that all highlighting disappears as you scroll, i dont see the 3 highligh. Keyboard Navigation: After double-clicking, use the arrow keys or PgUp/PgDn to move through the text. This sometimes preserves the highlighting. (stuck at 3) Find Box: Press Ctrl+F and enter the word you want to highlight. This will highlight all instances and usually persists when scrolling. (stuck at 3) Thanks, Best regards, Kenny Tan9Views0likes7Comments
