VerifyGeometry not parsing all the sub area

AnandThibbaiah

Hello Everyone,

I am adding decaps after routing optimization using "addFiller -doDRC false -honorPrerouteAsObs false -cell {}"

After that performing verifyGeometry -error 100000

While doing the above step verifyGeometry is stopping after checking one subarea

<CMD> verifyGeometry -error 1000000

 *** Starting Verify Geometry (MEM: 11229.1) ***

 

  VERIFY GEOMETRY ...... Starting Verification

  VERIFY GEOMETRY ...... Initializing

  VERIFY GEOMETRY ...... Deleting Existing Violations 

  VERIFY GEOMETRY ...... Creating Sub-Areas

                  ...... bin size: 1600

  VERIFY GEOMETRY ...... SubArea : 1 of 1

  VERIFY GEOMETRY ...... Cells          :  0 Viols.

  VERIFY GEOMETRY ...... SameNet        :  0 Viols.

  VERIFY GEOMETRY ...... Wiring         :  0 Viols.

  VERIFY GEOMETRY ...... Antenna        :  0 Viols.

  VERIFY GEOMETRY ...... Sub-Area : 1 complete 0 Viols. 0 Wrngs.

VG: elapsed time: 0.00

  Cells       : 0

  SameNet     : 0

  Wiring      : 0

  Antenna     : 0

  Short       : 0

  Overlap     : 0

End Summary

 

  Verification Complete : 0 Viols.  0 Wrngs.

 

**********End: VERIFY GEOMETRY**********

 *** verify geometry (CPU: 0:00:00.2  MEM: 1.0M)

 Can anyone tell me the reason for it ?? 

 

  • There is only 1 sub-area it has to check:

         SubArea : 1 of 1

     The bin size of each sub area is 1600.

  • Hey Brian,

    Thank you for the reply. The area of the block is more than that actually.

    What i am trying to do is add decaps using "addFiller -doDRC false -honorPrerouteAsObs false <decap_cells>"  

    After doing this i check for drc using verifyGeometry -error 100000.

    And after this whereever there are drc issues i remove decaps using "addFiller -cell <decap_cells> -fixDRC"

    But verifyGeometry is not doing the way i expected it to do it.

    Is it by default checking on a specific area ?

    Is there any variable to be set to verify drc over the whole block ? 

     

  • Can you explain why you believe it is not checking the whole block? Run getVerifyGeometryMode to see if the -area option is set. Run "setVerifyGeometryMode -reset" to set it to the defaults.

    Brian
