Occasional ContributorQPP 26.1 fails to generate PLL IP
Hello,
I'm unable to generate a simple PLL IP on a particular Win 11 machine. It works fine on a different Win 11 machine. Below is a partial log that shows the error. Note that I replaced my own user name with <username> below.

When I run the same PLL generation on a different Win 11 machine, I don't see mention of add_fileset_file in the log.
Below are the Generation settings.
I confirm that the problem of not being able to generate a PLL IP in QPP 26.1 went away when I used a different Windows 11 account that did NOT have a space in the user folder name under "C:\Users\". Note that this was change was made on the same PC that had the reported error above.
Therefore, it appears that Quartus has a bug in the Parameter Editor generate process that it can not handle spaces in the path it creates under the user's Temp folder during the generate IP process.
Please let me know how I can track this bug report and potentially know that it's fixed in a future QPP version or patch.
Thank you.

Hi,
Please confirm if my understanding is correct.
Did the issue you observed occur only on one specific Windows 11 machine, or are multiple of them failing?
Other than this IP, are there any other IPs that failed to generate?

Robert_PIN_ASAPHello Aqid.
Yes, that's correct. QPP 26.1 is only failing this way on one particular Win 11 machine for this Agilex 3 project. The same problem is NOT observed on our other Win 11 machine or two different Ubuntu Linux machines.
The Agilex 3 project uses four IPs, and only the PLL fails to generate. We also use QPP for a complex Cyclone 10 GX project, and there have been no observed failures to generate IP blocks on any machines.
Thank you.

Hello Robert,
Thank you for the detailed information.
Does this error also happen with any other QPP version that you have? Also, have you tried changing the other Agilex 3 devices? Or perhaps another device family? I appreciate your input on this.
In parallel, I will report this internally to further investigate this.Regards,
Aqid

May I know what you have changed in non-working window 11 machine compared to working window 11 machine?
- Robert_PIN_ASAP
Hello. As far as I know, there is nothing different about the Win 11 machines or the Quartus installation. I have re-installed QPP 26.1 twice, but the results are the same.
We have a much more complicated project for the Cyclone 10 GX, and there is no problem with the IPs on this machine for this project.
We're going to try different IPs for the Agilex 3 on this particular machine to see whether we can get a better idea of what is causing this problem. Thank you for your help.

Could you try recreate a new project and see?
- Robert_PIN_ASAP
Yes. Will do. I'll reply in a couple of days after we try a few more things here. Thank you.
