is it possible to run LVS when the layout and schematic are in different library?

SL,

It tends to help if you say what LVS tool you're using. My guess is that it's Assura, based on the "*.vlr" reference above. Are you running Assura from the command line, or integrated into Virtuoso? If in Virtuoso, you can just do Assura->Run LVS and then you can specify the lib/cell/view of both the schematic and layout (assuming the input is dfII in both cases).

Andrew.

 Hi Andrew,

Sorry for the confusion. I'm using ASSURA LVS. I've tried the integrated LVS in Virtuoso and it works. What I'm trying to do here is I would like to use command line to perform the same operation as the integrated LVS. I've already able to use the command line to run the LVS for which the layout and schematic located in same library. Now i would like to try to run it for layout and schematic in different library. 

 For the LVS which layout and schematic in same library. The method i use is create the rsf file and then use the assura *.rsf to run the LVS.

For layout and schematic in different library, I do not know how can i do it. Hope I can get some guidance here. Thanks

Thanks,

SL

SL,

In the RSF file you have:

avParameters(
  ?inputLayout ( "df2" "opamp090" )
  ?cellName "adc_sample_hold"
  ?viewName "layout_final"
  ?workingDirectory "./drclvs"
  ?technology "gpdk090"
  ?techLib "./assura_tech.lib"
...

The ?inputLayout line is specifying the library that the design is coming from, together with ?cellName and ?viewName

Also, in the RSF file you'd have:

avCompareRules(
schematic(
netlist( dfII "/scratch/andrewb/IC612_Whatsnew/design/drclvs/adc_sample_hold.vlr" )
)
bindingFile("/scratch/andrewb/IC612_Whatsnew/share/gpdk090_v3.9/assura/bind.rul")
)

or similar - i.e. a path to a "vlr" file. Inside the vlr file:

;----------------------------------------------------------------------------
; vldb RSF file
; Created by the Assura UI
;----------------------------------------------------------------------------

; form additions
avSimName = "auLvs"
avDisableWildcardPG = nil
avLibName  = "ether"
avCellName = "adc_sample_hold"
avViewName = "schematic"
avViewList = "auLvs schematic symbol"
avStopList = "auLvs"
avVldbFile = "/scratch/andrewb/IC612_Whatsnew/design/drclvs/adc_sample_hold.sdb"

Here you can see the lib, cell and view name of the design - as you can see I have a different library name. 

Regards,

Andrew.

Hi Andrew,

 Thanks for your help. I've manage to run the task that i wanted. Thanks!

Hi Andrew,

         I have also same problem(layout & schematic are different libreries) so that I followed your all suggestions.Now it's running clearly. 

When i ran lvs with assura in virtuoso, *runname.lrs file will be generated. From this file we can see all lvs report like net mismatches, mal-formed devices..etc.

But when i was ran lvs with commandline, *.lrs file is not generated. So, How can i get lvs errors  information....

Please help me on this.

Regards,
