Square within a square using Ruby

Pallavi

Hello, how can I generate a square within a square using KLayout, such that the inner square is hollow?

I need to create of loop of 100 such "squared-rings", each being in a different layer.

num = 100
w_inner = 1
w_outer = 2
dx = 3

include RBA
lv = Application.instance.main_window.current_view
ly = lv.active_cellview.layout
dbu = ly.dbu
cell = lv.active_cellview.cell

num.times { |i|

  w = w_inner/2.0/dbu
  inc = i*dx/dbu
  boxes_inner  = Box.new(-w + inc, -w, w + inc,w)
  region_inner = Region.new(boxes_inner)
  w = w_outer/2.0/dbu
  boxes_outer  = Box.new(-w + inc, -w, w + inc, w)
  region_outer = Region.new(boxes_outer)

  region = region_outer - region_inner

  layer_info = LayerInfo.new(i,0)
  layer_index = ly.layer(layer_info)

  cell.shapes(layer_index).insert(region)
}

lv.add_missing_layers
lv.zoom_fit
