    Calibre DRC error

    cnjhw99

      Hey guys, I am new to Calibre verification tools. I just got error message after I run DRC (it pops out when DRC RVE starts):

      "Format error at line 8

      Line too long or other failure."

       

      The DRC check was completed successfully. I checked the result file (ASCII format). The first few lines are:

      "pre_drv 1000
      DRAWN_OFFGRID

      ..."

       

      You can see the line 8 is blank... I have no idea how the error comes. The DRC RVE did not display the drc errors line by line...  So guys please help me out. Thanks for any idea...

          The question is still there. Any comments?

           

          BTW, I did LVS with the same cell, everything was just fine. Calibre LVS RVE displayed the LVS errors, so I can correct them one by one...

            I see something that may be a little odd in that example. I'm going to try a quick experiment and let you know if I come up with anything.

              My experiment ran okay, I did not see the same error as you when I tried to recreate it.

               

              I was suspecting something with the TITLE statement, especially with that blank line, but I was able to load results with a similar title in my experiment.

               

              Still, since the line reported in the error is right there near the title, you might consider an experimental run where you comment out the TITLE line in your rulefile in case it helps or changes the behavior for you.

                Hey Chris,

                 

                It's amasing!!!! The error message just gone and everything works like perfect after I comment out the TITLE line in the rule file! Thank you so much!

                 

                Have a nice weekend!
