Re: Unable to Generate .sof File in Quartus Prime Standard Edition 15.1 – 30‑Day Evaluation Mode
No — the 30‑day evaluation mode of Quartus Prime Standard Edition does not support generating programming files, including .sof. https://www.macnica.co.jp/en/business/semiconductor/support/faqs/intel/118773/ Since the evaluation itself does not permit .sof generation, there are only two valid options: -Option A — Use Quartus Prime Lite Edition (Free): Quartus Lite does allow .sof generation and does not require a license, provided your design does not use licensed IP. This is the recommended method for evaluation requiring programming. -Option B — Use a Licensed (Non‑Evaluation) Quartus Standard Edition: A valid Standard (or Pro) Edition license will allow full .sof generation. The 30‑day evaluation mode alone will not. Regards, Richard Tan24Views0likes0CommentsRe: Quartus/Signaltap complains about wrong version
A few things you can try to troubleshooting: 1. Run Quartus (and Signal Tap) with Administrator privileges. 2. Check whether any security software, antivirus, or endpoint protection could be blocking Quartus from generating or accessing the SLD files. 3. Delete the db/ and incremental_db/ folders, then recompile. Regards, Richard Tan8Views0likes1CommentRe: Shift Register Inference on Intel FPGAs – LUT-based Implementation Similar to Xilinx SRL?
Good observation — that behavior is expected. Quartus will infer RAM‑based shift registers when the RTL is compatible with the device memory architecture. In particular, adding a reset to the shift chain typically prevents inference into MLAB/M20K and leaves the implementation in flip‑flops. The Quartus document below explicitly call out that coding styles like asynchronous resets can block RAM inference and force FF implementations: https://docs.altera.com/r/docs/683641/25.3.1/quartus-prime-pro-edition-user-guide-design-optimization/guideline-remove-fitter-constraints?tocId=tmmzgVOTMhoEtv7TLENcLA Additionally, on HyperFlex devices (Stratix 10 / Agilex), inference thresholds are higher to preserve Hyper‑Retiming.

Our team is still working on the fix, and at the moment we don’t have a confirmed completion date. Could you please try retrieving the license again in about two days? If the issue is resolved earlier, I will notify you right away. Thank you for your patience and understanding. Regards, Richard Tan54Views0likes1CommentRe: Repeat of a Questa License Issue
