LVS not running

Hi all,

1)         I got following error in log file when I run LVS. Is there any need of schematic change or Compare rule file change.

         ** Parallel MOS combined:
  1st MOS: L = 3e-08 W = 4e-07 m = 1
  2nd MOS: L = 3e-08 W = 2e-07 m = 1
  Resulting: L = 3e-08 W = 6e-07 m = 1
*Error* times: can't handle ("1" * 6e-07)
*ERROR* User supplied SKILL routine failed: '(compareMOS)'. SKILL interpreter could not execute this SKILL function.
    Probably usage of the function is not correct. Try to revise the syntax:
    (compareMOS('(nil l 3e-08 w 6e-07 m 1) '(nil m "1" l 3e-08 w 6e-07)))


*****  nvn fork terminated abnormally  *****\

In compare rule file for comparision of mos devices:

  procedure( compareMOS( layPlist, schPlist )
    prog( (missingLay missingSch)

; IF m (m factor) IS MISSING, SET IT TO 1

      when( !layPlist->m  layPlist->m = float(1) )
      when( !schPlist->m  schPlist->m = float(1) )

; IF W or L IS MISSING GENERATE A PARAMETER MISMATCH
            
      foreach( prop '( w l )
        unless( get( layPlist prop )
          missingLay = cons( prop missingLay )
        ) ;unless
        unless( get( schPlist prop )
          missingSch = cons( prop missingSch )
        ) ;unless
      ) ;foreach

; REPORT ALL MISSING PARAMETERS

      when( ( missingLay || missingSch )
    when( missingSch
       sprintf( msg1 "Sch MOS missing parameters: %s"
             buildString( missingSch ","))
    ) ;when
    when( !missingSch
       sprintf( msg1 "Sch MOS W/L/m %g %g %g"
     float(schPlist->w) float(schPlist->l) float(schPlist->m) )

         buildString( missingLay ",") )
    ) ;when
    when( !missingLay
       sprintf( msg2 "Lay MOS W/L/m %g %g %g"
     float(layPlist->w) float(layPlist->l) float(layPlist->m) )
    ) ;when
    sprintf( msg "Err: %s ; %s" msg1 msg2 )
    return( msg )
      ) ;when

      layM = layPlist->m

      layL = float( layPlist->l )
      schM = schPlist->m
      schW = float( schM * schPlist->w )
      schL = float( schPlist->l )
      
      diffW = 100 * (abs( layW - schW ) / schW )
      diffL = 100 * (abs( layL - schL ) / schL )

   ) ; end prog
  ) ; end compareMOS

2) I need virtual connection set up when I run LVS. I mean when we add same labels or pins for two nets in layout then it will automatically take that as same net.

Thank you,
