IC5141 - LEFOut failed.

kb how

Hi,

I'm working on old process which using still IC5141. Trying to lefout a very simple layout (just with shape and pin only), but encountered error as below. I'm having difficulty in troubleshooting. 

May need some advice for those whom encountered the same issue to point me the problematic part.

Version: "@(#)$CDS: layoutPlus.exe version 5.1.0 02/02/2009 09:56 (cicln04) $"

Thanks a lot.

  • Hi How,

    What version of Linux are you running on? Perhaps it is too new (RHEL6?) I'm not sure but there are changes between, say, RHEL4 and later releases regarding colour, for example the location of rgb.txt in RHEL5 is /usr/share/X11/rgb.txt rather than /usr/lib/X11/rgb.txt according to a case I found...

    I don't know if this helps, but try looking at your setup to see if this file might be the culprit?  ALso, your .cdsenv contains things from a later release that IC5141 does not know about, either move it aside, or create version specific cdsenv files.

    Regards,

    Lawrence.

  • Hi Lawrence,

    Thanks. I'm working on RH5 machine but submit job to lsf (RH4) machine to get my work done. Will this causing the LEF to failed since i already doing the job in RH4 machine?

    Let me try remove .cdsenv file anf try again.

    By the way, it this related to anything that we need to set in techfile?

     

  • Hi,

     I managed to generated the LEF file of a simple design. What i do is to added prRules section into the techfile. Yeah!

    But, the output lef is has only technology information. All design related info such as MACRO, SITE is missing from the left file. Do i need to add any property like prCellType and prCellClass into my layout view in order to get it work? I tried it but failed also.

    You advice is value for me. Thanks

  • I got this error.

  • Did you generate the cell list at the bottom of the LEF form? Without this it will only output technology LEF.

    Regards,

    Andrew.

  • Hi Andrew,

    Thanks. I managed to get the LEF-out works by adding properties information in the cell as below.

       prCellType     "macro"
       prCellClass    "core"        
       maskLayoutSubType "abstract"

     Now the lef-out is working fine, Thanks for the help.
