Positioning the instances in Layout editor by using SKILL

RFStuff

 Dear All,

I am trying to place copies of an instance/object ( say a simple via ) with 'x' distance separation in X-direction.

Is there any in-built feature already available in IC5141 ?

Otherwise, is there any solution ( SKILL script) already posted in the forum ? I searched but couldn't find so.

The code needs three functions:

1) Find the cordianate of the OBJECT/INSTANCE ( this I have already found in the Forum)

2) Copy the object. For this what is the SKILL function ?

3) Paste the desired distance separation ( For palcing wht is the simple SKILL function)

Couls anybody please tell regarding this.

Kind Regards,

    I suspect it didn't work for you because your shapes are not symmetrical, and so when it flipped around the centre, whichever point you are measuring to moved relative to the centre of the objects being flipped around.

    I took the shapes in the picture below, and did this:

    existingObjs=geGetSelSet()
    geDeselectAll()
    shiftTransform=list(60:0 "R0" 1)
    destCv=geGetEditCellView()
    foreach(obj existingObjs
      newObj=dbCopyFig(obj destCv shiftTransform)
      when(newObj geSelectFig(newObj))
    )
    CCSflip()

    And I get a nice symmetrical layout - but what the "pitch" means is rather dubious.

    Essentially I think you want to compute some point that  you want to be the symmetry line, and then use that as the reference point - either using the ?relativeTo 'refPoint approach, or a similar computation in your own code. If you look in CCSflip, you'll see it computes the overall transform relative to some "origin" - i.e the point about which you want to flip or rotate - by doing:

             ;-----------------------------------------------------------
             ; Combine the transform to do a shift to the origin,
             ; rotate/flip, and then shift back again
             ;-----------------------------------------------------------
             (setq transform
               (dbConcatTransform
                (dbConcatTransform
                 (list (mapcar 'minus origin) "R0")
                 (list 0:0 orient)
                 )
                (list origin "R0")
                ))

    Regards,

    Andrew.
