Please, do not release another version of Quartus until you fix the file length problem in windows
- 1 month ago
Are you referring to the maximum file path length? If so, this is a Windows limitation.
Windows limits the combined length of a file name and its path to 260 characters. If your project path exceeds this limit, Quartus may be unable to access the required IP or design files.
Additionally, the Quartus Prime Pro 26.1 installer includes an option to enable Windows Long Path Support by default. Older installers may not provide this option.
Alternatively, you can refer to the KDB below for instructions on enabling long path support in Windows.If the issue persists after enabling long path support, could you share more details, such as the exact compilation error message or logs?

Thank You. I guess my point was, knowing it is a limit of windows, why create automated generated file names like this...
..\baseline-a55\ip\hps_subsys\emif_io96b_hps\emif_io96b_hps_emif_io96b_hps_420_pcm7idi\synth\emif_io96b_hps_emif_io96b_hps_420_pcm7idi\emif_io96b_hps_emif_io96b_hps_420_pcm7idi.v
I couldn't get the Golden reference to build unless I had it right at the c drive. I guess that was really what I was getting at. But looks like there is a check box at start up I missed at installation
Hi dscoope,
Thank you for the clarification.
Platform Designer generates these filenames to preserve the unique hierarchy and instance identity of the generated IP. To help reduce Windows path-length issues, you may:
1. Enable the Windows Long Path Support option during Quartus installation.
2. Avoid placing the Quartus Prime project in a directory far from the drive location.
We also appreciate your feedback regarding the lengthy and repetitive folder and file names. While we cannot guarantee changes will be implemented, we will document the feedback for future consideration.
Thank you for your understanding!
