How to change from one layer to other layer

sailesh

 HI ,

      i need the code to change the metal layers in layout, EX: when the code is loaded all the M1 layers in layout should be replaced by M2 automatically. iam able to do till gettin the available layers..but iam not able to replace them

  • You could, though it would be more efficient to find the matching lpp object first and then find its shapes, then iterate over those shapes to change the layer and purpose.  I don't have an example to hand, but it would be something like the following:

    m1lpp = car(setof(lpp geGetEditCellView()~>lpps lpp~>layerName=="M1" && lpp~>purpose=="drawing"))

    foreach(shape m1lpp~>shapes shape~>lpp=list("M2" "drawing"))

    Typically the number of shapes to process is an order of magnitude or more greater than the number of distinct layer-purpose pairs, hence the probable efficiency gain. YMMV depending on the design of course.
