ASSURA LVS PROBLEM FOR AMI C5 PDK

Hi checkmate

When running using DFII schematics, we cannot have both "dfII" and "cdl" inputs in the avCompareRules section. If you check your rsf file using the "View rsf" button on the lvs form, you should be able to find something similar to:

avCompareRules(
   schematic( cdl ".../box.cdl")
   ...
)
...
avCompareRules(
   schematic( dfII ".../yourDesign.vlr")
   ...
)

Your current files are good for running Assura using cdl/verilog inputs. Here is how you can resolve the problem:
a. Comment out the line in following line in compare rules using a semi-colon. E.g.
;schematic( netlist( cdl strcat(getShellEnvVar("AMI") "/tech/ami500hakx/current/cdl/box.cdl" ) )

b. In the lvs form, press the "Netlisting Options" button. A form appears, at the end of the form, there is a field for adding cdl netlists. Please add "box.cdl" file using this form.

c. Now run lvs. It should be ok now. If you examine the "design.vlr" file in the run directory, you should see something similar:

avSimName = "auLvs"
avDisableWildcardPG = nil
avLibName  = "myLib"
avCellName = "myDesign"
avViewName = "schematic"
avViewList = "auLvs schematic symbol"
avStopList = "auLvs"
avVldbFile = "/myPath/avLVS/myDesign.sdb"
avReadCDL( "/myPath/box.cdl" )

By the way, if it is possible, please upgrade to the latest version of Assura. Assura31 is too out-dated. : )

 Hello Quek,

I am little bit confused!

 When you mentioned that "Comment out the line in following line  in compare rules using a semi-colon."

 So, this is my new compare.rul file:

;#####
; avCompareRules (AMIS Technology Development)
; $AMI/tech/common/current/assura/compare.rul (AMIS)
; 03/26/2002 Updated BRD
; 04/20/2002  DAS  Fixed path to box.cdl
; 04/22/2002  BRD  Restored path to box.cdl
; 05/15/2002  BRD  noMerge series caps, merge parallel
; 07/08/2002  BRD  added back bind.rul
; 09/05/2002  BRD  added swapPins for caps
; 09/13/2002  BRD  added filterDevices for presistor and pcapacitor
;                  to filter from schematics
; 10/16/2002  BRD  Set bind.rul path from beta to current
; 11/06/2002  BRD  added ls,ml,om,qo swapPins
; 12/18/2002  BRD  changed compare percents to 0.5 from 0.005
;                  added pdiode filter
; 01/08/2003  DBM  Jake tested the changes to follow. 
;           added cdl versions of pdiode and pcap
;           added commented out versions of a filter
;           statment and bindfile as well as the
;           listXRef() and upped the autoPinSwap().

) ; end of avCompareRules (AMIS Technology Development)

So,  basically commented out everything except the avCompareRules line in compare.rul.

I also added the cdl netlisting in the Netlisting Option window.

Then when I ran the LVS, then it works fine.

 I just want to double check is that you wanted me to do.

Or did you want me to  just comment out the "schematic (netlisting(cdl strcat(getShellEnvVar("AMI")"/tech/ami500hakx/current/cdl/box.cdl"))" line and leave the others uncommented.I tried that but then LVS gives me errors.

 Please let me know.

Thanks

Hi checkmate

Yes, I meant only to comment out the line containing box.cdl. May I know more about the new erros which you have encountered?

Best regards

 Hello,

 IF I only comment out this line in compare.rul file.

;schematic( netlist(cdl strcat(getShellEnVar("AMIS") "/ami500hakx/Rev6.17/cdl.boc.cdl"))

I get the following errors:

*Error* eval: undefined function -  mergeSplitGate

*Error* load: error while loading file - "/home/jhasan/MAI_C5/LVS_RUN/TEST.rsf"

*Error* load: error whule loading file - "*loadstring*"

Errors exist in master control file "home/jhasan/AMI_C5/LVS_RUN/TEST.rsf".

Also, I am attaching my TEST.rsf file.

Please let me know.

 Thanks

Hi checkmate

Sorry that I made a mistake in my previous mails. We should not comment out the entire line, only the "netlist..." part. So it should be:

schematic( ; netlist(cdl strcat(getShellEnVar("AMIS") "/ami500hakx/Rev6.17/cdl.boc.cdl"))

Best regards

Hello,

Yes, LVS is finally working after the changes you suggested in your last e-mail.

Thanks
