A question about cdfUpdateInstParam() ?

 Hi! all,

           I am trying to instantiate transistors from schematic to layout. Initially I wrote this code(not hierarchical code).

  procedure(new_gen()
cv = geGetEditCellView() ;where cv is the 'schematic cell view

let( ( i )

i = 0
foreach(inst cv~>instances
  if(inst~>libName == "gpdk090" then
      case(inst~>cellName
      (("pmos1v" "nmos1v" "pmos2v" "nmos2v")
          mos = dbOpenCellViewByType(inst~>libName inst~>cellName "layout")
          if(inst~>m == "1" then
          lay = dbCreateInst(target mos inst~>name i:0 "R0") ;where target is the layout window
          dbCopyProp(inst lay)
          cdfUpdateInstParam(lay)
          ;println(inst~>m)
          else
          if(inst~>m != "1" then
          for(r 1 atoi(inst~>m)
          name = strcat(inst~>name "." artMakeString(r))
          lay = dbCreateInst(target mos name i:0 "R0")
          dbCopyProp(inst lay)
          cdfUpdateInstParam(lay)
          lay~>m = 1
          ;println("lap2")
          i = caadr(lay~>bBox) + 3
          )
          )
          )
          i = caadr(lay~>bBox) + 3
          )
      (t
          println(inst~>cellName)
      )
      );case
  )
  );foreach

);let
);proc
new_gen()

Now the problem is I am getting the transistors (pmos&nmos) which are having  same properties.(Also thse properties reffered to the transistor which is encountering at first time in 'cv~>instances list' )

Can someone correct this code for me, please.....

Thanks in advance...
