Assura LVS using: setenv OA_UNSUPPORTED_PLAT linux_rhel40_gcc44x

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 Quek,

Unfortunately, I can see that there is a way to upload media; but not an ascii file. So, I have copied it.

best regards,

alan
