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,

    To copy to an absolute coordinate, you need to produce a concatenated transformation which moves back to the origin, then to the location you want. So for example, if you want to copy the lowerLeft of your object to a location xy, you'd do:

    dbCopyFig(instId cvId dbConcatTransform(list(-xCoord(lowerLeft(instId~>bBox)):-yCoord(lowerLeft(instId~>bBox)) "R0" 1) list(xy "R0" 1)))

    I don't really understand your second question, since a relative movement doesn't matter which coordinate it is with respect to - all coordinates in the bBox will move by the same relative amount.  Maybe you're talking about an absolute move - in which case something like my suggestion above would make sense - you just compute the first transformation using a different coordinate on the shape (such as the upperRight rather than the lowerLeft).

    Regards,

    Andrew.
