    Calibre LVS


      Hi all,


      I am trying to run Calibre LVS but each time I get a message error window with the following message "Layout export failed or was cancelled"

      I am ussing the Linux x86 platform and I have tried with different versions of Cadence. IC5141 USR5, USR4, USR3.

      My coworkers have no problem running it.

      Thank you for your help


      Here is a copy of the transcript:

          Hi Said,


          I think some other people have seen this but I'm not aware of a final conclusion or complete answer. Some have suggested it appears to be a problem with the Cadence installation that happens on multiple versions.


          Are you using 64bit mode? You may be successful with 32bit mode in this case.


          One thing I think is interesting... the error message refers to "auCore.cxt" but I wonder if there is a typo somewhere... was it supposed to be "auCore.txt" instead? Does a file with a similar name exist at that path?




          or ?

            Hi Chris,



            The first time I ran into this problem, I was a bit puzzled. I was not using the 64bit mode and yet it was looking into the 64bit folder for the auCore.ctx.

            I looked around and found the auCore.cxt at the following location: "/tools/cds5141usr5/tools.lnx86/dfII/etc/context/"

            but not  in the 64 bit folder:"/tools/cds5141usr5/tools.lnx86/dfII/etc/context/64bit/" where it is looking for.

            I am tempted to just copied it and see what happens.

            Thank you for your time.
