how to write 3 i/p AND gate in skill code

venuuuuu

 hi all,

1) i know the syntax for two input AND gate in layout as shown below.

leLayerAnd(  cv     list("prBoundary"   "drawing")     list("NWELL"   "drawing" )  list("PWELL"    "drawing"))

  But i need more than 2 i/p AND gate syntax

  Let me know how to write it in skill.

     thanks andrew,

    It's working now with all your help. Now iam trying to develop a skill code for fill the free space in my layout with substrate contacts. substrate tap consists of PWELL,PIMP,DIFF,METAL1,M1_DIFF contact. these layers are filled in layout  where there is no layers except prboundary. my code is

    cv = geGetWindowCellView()
    geSelectAllFig()
    ;for filling pwell where  nwell,metal1,poly,diff doesnot has.
    leLayerOr( cv list("DIFF" "drawing") list("MET1" "drawing") list("y0" "drawing"))
    leLayerOr( cv list("y0" "drawing") list("POLYG" "drawing") list("y1" "drawing"))
    leLayerOr( cv list("y1" "drawing") list("SDNW" "drawing") list("y2" "drawing"))
    leLayerAndNot( cv list("prBoundary" "drawing") list("y2" "drawing") list("SDPW" "drawing"))
    leLayerAndNot( cv list("prBoundary" "drawing") list("y2" "drawing") list("y3" "drawing"))

    ;for pdiff in pwell
    leLayerSize( cv list("y3" "drawing")  -.12  list("PIMP" "drawing"))
    leLayerSize( cv list("y3" "drawing")  -.2  list("DIFF" "drawing"))
    leLayerSize( cv list("y3" "drawing")  -.2  list("MET1" "drawing"))

    ;for deleting y0,y1,y2,y3 layers
    geDeselectAllFig()
    leSetEntryLayer( list("y0" "drawing"))
    leSetAllLayerVisible(nil)
    leSetEntryLayer( list("y1" "drawing"))
    leSetEntryLayer( list("y2" "drawing"))
    leSetEntryLayer( list("y3" "drawing"))
    geSelectAllFig()
    leHiDelete()
    leSetAllLayerVisible(t)


    i inserted pimp, diff, metal layers in free space. but i dont know how to get contacts on metal1 and diff. so please help me to do it. iam on cadence virtuoso 5.1 version
