    Calibre - PEX pre-trigger issue


      Hi everyone,


      I have recently started using Calibre PEX and have faced this issue and I just cannot figure out how to fix this issue.


      Everything from Calibre DRC and LVS is working perfectly. However, when I try to run PEX, this statement as shown below pops up and I cannot figure out why it is happening:




      I have tried following to fix this problem:

      1) Check to make sure that $MGC_HOME and $CALIBRE_HOME is setup properly

      2) Check the environment setup like this:

      3) Make sure $PATH is properly setup

      4) Check pre-trigger itself



      One thing I was able to noticed was that if I remove the phrase "pre_reduction", PEX runs, but returns wrong result. So... it seems like this phrase "pre_reduction" is the issue, but I really am out of ideas of how to fix this problem.



      If anyone can give me any kind of suggestions (and I mean any), please do so.


      Thank you very much,

          1) Specify the complete PATH for your script.


          2) check if your script is an executable file

            Hi Jean,


            You were correct. It was the $PATH issue. In case if anyone has the problem as I did, the solution to fix it is you need to specify the path in your .bashrc (at least for me) where your "pre_reduction" script lies in (this is the key part, as I didn't know pre_reduction was a script).


            So for my case, this script was residing in a directory called


            /apps/65cmoslib/$DKROOT/bin ($DKROOT will be different for everyone, just think of it as your design kit directory place holder)


            Therefore on my .bashrc, I included


            PATH=other cadence path:$PATH

            PATH=other stuff:$PATH


            export PATH


            and after that, I recreated my library and created new layout cell view. Then PEX started working.


            Hopefully this helps !
