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 Prabhakar,

    Just noticed I'd not replied to this. I don't have time to adapt your code (and I'm not sure even this is what you want), but I can answer your question about how to handle area specified as "(0:0 0.25:0.25)".

    item=linereadstring(area)
    when(listp(item)
      ; just take the first item in the list
      item=car(item)
      myArea=cond(
        (numberp(item) list(0:0 sqrt(item):sqrt(item)))
        (listp(item) eval(cons('list item)))
        (t warn("Unrecognized area format: %L\n" area)
      )
    )

    Note because the list has got ":" in, these are an operator which need to be evaluated. You can't just use evalstring, because it's not a properly formed SKILL function call - so the linereadstring parses the text, and then I cons on a "list" onto the beginning and eval that. The code above also handles the situation where the area is specified just as a single number. You could make it more or less flexible to suit your needs.

    Even with this, it won't prompt you to draw the box yourself. You could add stretch handles on (as I've mentioned) to allow it to be interactively resized after creation though.

    Regards,

    Andrew.
