ContributionsMost RecentMost LikesSolutionsRe: VHDL Conditional analysis example I too have observed this phenomenon emerge spontaneously around Jan 11. I believe it is part of the constellation of symptoms, one of the intermittent failure modes, caused by a broadly affecting Quartus Pro bug discussed in the following thread: https://community.altera.com/discussions/quartus-prime/quartus-pro-25-3-crash-using-rhel78/349584/replies/349607 Re: Quartus Pro 25.3 crash using rhel7/8 Thank you, ShengN_altera. Can you please provide an estimated time frame for the patch? Thanks, -Roee Re: Quartus Pro 25.3 crash using rhel7/8 I too am seeing similar issues that seem to have cropped up out of nowhere in the past 48 hours. Intermittent crashes of Quartus Pro (running in shell mode) occurring seemingly at random at varying stages of the flow, and also intermittent failures immediately upon launch of Quartus Pro (in shell mode) resulting in an identical error message and stack trace to those shown in the original poster's screen shot quartus_4.PNG. I'm seeing this occur with multiple versions of Quartus Pro (24.2, 25.1, 25.3.1) running on several different machines and different operating systems (RHEL 8 and RHEL 9), all of which were working perfectly up until the past couple of days. -Roee Re: IOPLL non-dedicated feedback option doesn't work correctly @AqidAyman_Intel, The issue has not yet been addressed. It has only been scheduled to be addressed. I'd like to leave this thread open please until the issue has actually been addressed, which by your estimate would happen around 2024Q4 - 2025Q1. Thanks, -Roee Re: IOPLL non-dedicated feedback option doesn't work correctly Thank you. Re: IOPLL non-dedicated feedback option doesn't work correctly Hi @AqidAyman_Intel , Please clarify about "24.3.1". Normally, a Quartus Pro quarterly release like the upcoming 24.3 would be versioned as 24.3.0. Is there a planned "update 1" for 24.3 sometime after the initial release of 24.3? Is that what you mean? Or what is 24.3.1 exactly and when can we expect it? Thanks, -Roee Re: IOPLL non-dedicated feedback option doesn't work correctly Hi @AqidAyman_Intel , Which upcoming Quartus release would that be? 24.3? Re: IOPLL non-dedicated feedback option doesn't work correctly Hi @AqidAyman_Intel , I'd like to make sure that I clearly understood your response: The internal team acknowledges that this mode doesn't actually work correctly, but they don't intend to fix it? Is that correct? Are they simply going to document the fact that it doesn't work? Are they going to remove this non-working optional mode from the IP and Quartus tool chain as well as the documentation? If I do "request a patch" to satisfy Intel's internal triage processes, will they then fix it just as a point-solution patch for me only? Or will they then fold the fix into the subsequent mainline releases? Please clarify. Thanks, -Roee Re: FMC connector on DK-DEV-AGF014EA dev kit? @Jeet14, it's been over 3 months now and still no correction has been made. The web site still shows the same false and misleading information. Re: IOPLL non-dedicated feedback option doesn't work correctly Hi @AqidAyman_Intel , Thank you for getting back to me. No, it is not blocking me at this time. And no, I'm not requesting a patch. It will suffice if your internal team gets to the bottom of it and fixes the problem in an upcoming release. Please keep me posted on their progress. Thanks, -Roee
