How to stretch sub rectangles created with rodCreateRect() ..?

IC Layout

Hi, All, I have created an object which is composed of three layers (M2 being master, M1 and VIA1(as array) being sub rectangles in subrectArray section).
When I stretch this object except M1 layer both M2 and VIA1 are stretching correctly. It has been given that in the roduser.pdf inorder to stretch rodobjects correctly
we need to provide one argument i.e n_spaceY .. But I want the M1 layer to be stretched along with the M2 layer without any offset values..
I hope the problem is understandable and I have written it correctly..
Here is my code..............

procedure(box_box()
  bbox = enterBox()
          ll =  lowerLeft( bbox )
          ur = upperRight( bbox )
          llx = xCoord(ll)
          urx = xCoord(ur)
          X = urx-llx
          lly = yCoord( ll )
          ury = yCoord( ur )
          Y = ury - lly
          l1 = list(X Y bbox)
)
procedure(rect1()
box_1 = box_box()
rodCreateRect(
      ?layer    list("M2" "drawing")
      ?cvId     geGetEditCellView()
      ?bBox     nth(2 box_1)
      ?returnBoolean t
            ?subRectArray
              list(
                  list(
                      ?layer    list("M1" "drawing")
                      ?width    nth(0 box_1)
                      ?length   nth(1 box_1)
                      ?gap      "distribute"
                       )
                  list(
                      ?layer    list("VIA1" "drawing")
                      ?width    0.1
                      ?length   0.1
                      ?gap      "distribute"
                      ?spaceX   0.13
                      ?spaceY   0.13
                      ?lowerLeftOffsetX 0.07
                      ?lowerLeftOffsetY 0.07
                      ?upperRightOffsetX -0.07
                      ?upperRightOffsetY -0.07
                  )
              )
  );rect
)
rect1()

One more small question, is it possible to have properties "rows" & "columns" to the above object? If so, please someone guide me in achieving this ....
Thanks in advance..

  • Hi! Mr.Andrew, With your suggestions and with one of the below code (which is in sourcelink "CCSdependentPcell.il") I got similar kind of solution for which I am trying for.
    But my idea is to draw a box interactively and with this area the following code has to place the instance..
    Means the instance form should expect to draw a box to place instance with the drawned box area..
    I tried giving "area" as a string like this
    (area "string" "(0:0 0.25:0.25)")
    But if I evaluate area with evalstring its not taking it as a list...its giving an error..
    I hope you are getting my problem....
    Here is the code.... Please drive me to solve this problem...
