    It's a UNIX command that shows the user id information (user id and group id information).

    If you don't want to share that, try using:

    chmod o+r /home/MSRF_Low_Power/PDK/Cadence_OA/tn65cmsp007k3_1_7a/skill/64bit/tsmcN65Tool.cxt
    chmod o+r /home/MSRF_Low_Power/PDK/Cadence_OA/tn65cmsp007k3_1_7a/skill/tsmcN65Tool.cxt

    (as user "1966") and then see whether it works. I'm just trying to ensure that you have read permission on the files.

    OK, so that's the problem. The file is owned by a user with uid=1966, and gid=1965, and only users with that uid or gid can read the file. You are uid=1009 and gid=1009, so there's no "world" or "other" access to the files. The chmod was trying to fix this, but you need to do this as a user that has UNIX permission to change the permissions (either uid=1966 or as root).

    It's a pure UNIX permission issue here, nothing really to do with Cadence tools.

    i have installed the pdk  in the root, but  other users can acess the file and read it.

    so what permission i need to change then ??  can you please suggest , i  can make the changes in the root as i have password.

  • in reply to rtyuy

    Well, clearly the permissions are not correct for these files as I said. You need to run the "chmod" commands that I mentioned before (as root) - this will change the permissions to -rw-r--r-- (note the r in the final "other" triplet). That's what the "o+r" is doing - it's adding "read" access for "others".
