Assura LVS using: setenv OA_UNSUPPORTED_PLAT linux_rhel40_gcc44x

bartman

I am having an LVS problem and I noticed this post.  I am not sure if anyone is still around (based upon the 2010 responses) to reply.

At the end of the lvs report I have the following message:

Preprocessing layout network phase 2
*ERROR* Device 'pfet(Generic)' on Schematic is unbound to any Layout device.
*ERROR* Device 'nfet(Generic)' on Schematic is unbound to any Layout device.
*ERROR* UnBound devices found.
Info: All devices must be bound or filtered for comparison to be run.
Exiting nvn.

It implies that I have devices in the schematic which cannot be matched to a layout device.  I have tried this in calibre and succeeded in getting a clean LVS; so I know the layout and schematic do match.  I would like to have assura working as well.  One possible issue is in the use of multiplicity; m>1 for every transistor in the schematic.   The LVS checks using assura for devices which have m=1 have worked.  Is it possible to fix this problem ?

    Hi Alan

    I totally agree with you that Assura should also give the same LVS match results as Calibre.

    Would you please upload the .cls file (e.g. design.cls) in the run directory? This is the LVS report file.


    Best regards
