I am in IT and I am seeking help / discussion with Quartus software developers.
I am not familiar with how to use your tool - again, I am in IT. The user experienced an issue and I knew the reason, so I am here trying to get help on addressing it from your side.

Subject: unable to generate quartus ip intel_rtile_cxl_top_cxltyp2_ed with quartus/24.1

So here is the cause of the problem with 24.1. We in IT handles the tool installation requests. We follow strict policy to chmod permission to remove write access (chmod -R ugo-w) of the install directory after the installation is done to prevent accidentally changes. We apply this to all the EDA tools we install - although, there has been a couple tools with exceptions.
The problem is when the user run 24.1, your tool performed a recursive copy of some kind from the <install path>/ip/altera directory. The files and directories inherit the source content permission. (r-xr-xr-x for directories, r--r--r-- for files) Because the source directory "avmm_ic" has no write permission, after the content is copied to /tmp, the directories and files retains the original permission except making the user the owner of the files/directories, but the process tries to write a tcl file in there and fails because the directory has no write permission.
The user has also stated the same routine runs perfectly fine with 23.4 - the issue only happens with 24.1. We remove write access for both versions so why does it work with 23.4 and not 24.1? Would it be possible your copy routine has changed from 23.4 to 24.1? Theoretically, the tool should not assume the permission to be write-able and perform a chmod +w after a directory copy - this is what I need your help to look into because it does not make sense for us to change the directory owner permission to writeable for the sake of a copy process so the engineer - who takes over ownership of the copied directory, and is not using the same login as the installer id

Hi there,
The current case has been assigned to the CXL IP domain. Although I have not encountered this issue before, I have a few points to confirm:
- Does the customer have the permissions to use CXL in version 24.1? Since this IP is restricted, I need to clarify whether the customer's 24.1 includes the CXL IP license.
- The mentioned script contains an error, but it does not appear to be generated by Quartus, as there is no corresponding error ID. Could the customer try performing the above operation in the Quartus GUI and provide feedback on the error?
Best regards, WZ

Thanks for replying.
1. I looked at the license file and it appeared to be a 3-month eval license. That may explain why the users haven't asked for additional directories to add write permission.

2. I don't know how to answer that. I just relay what I was told - that the issue didn't happen on v23 but on v24.1. If you are saying Quartus does not have a routine that does a copy process from the IP install area to the /tmp area, inheriting the owner's permission, I will have to ask the original user submitting the ticket on your side and mine to work with you. Then again, your support system is so difficult to work with, it took almost 2 months to reach this point, I suspect the eval would have expired before we can get to the bottom of this.

Hi there
- For issues regarding Quartus license, you can find the relevant IP license in Quartus -> Tools -> License Set Up. It seems the customer is using the CXL_type2 IP, so you can check if there is a license labeled "CXL IP for Device Type2..." or similar. Alternatively, you can compare the license files between versions 23.4 and 24.1 to identify any differences.
- The log shows that you raised the issue in mid-June, but I am not sure where the remaining time has been spent.
- You can ask the customer to use the Quartus GUI to generate the error description and attach the error report.
Best regards,
WZ
