How to get a text list of layers in a cell

  Nothing can't be done with a script

  ly = RBA::CellView.active.layout
  cell = RBA::CellView.active.cell
  
  layers = ly.layer_indexes.collect { |li| info = ly.get_info(li); [ info.layer, info.datatype, li ] }.sort
  
  puts "Non-empty layers of cell #{cell.name} (including subcells):"
  layers.each do |layer,datatype,li|
    if ! cell.bbox_per_layer(li).empty?
      puts "  #{layer}/#{datatype}"
    end
  end
  

  (Create a new macro in the IDE under "Ruby", paste this code and run it. The printout gives the BOLD layers of the currently selected cell.

  Hi Matthias,
  Can this be used to get the actual layer name as well ie:metal1 ... metal2 etc

  if you have GDS, layer names are not available in the layout, so they cannot be retrieved from the layout database. You'll need some translation table which you can derive from the layer table in the layout view:

  ly = RBA::CellView.active.layout
  cell = RBA::CellView.active.cell
  
  layers = ly.layer_indexes.collect { |li| info = ly.get_info(li); [ info.layer, info.datatype, li ] }.sort
  
  # fetch display names
  names = {}
  RBA::LayoutView.current.each_layer do |lref|
    if lref.name != "" && lref.cellview == RBA::CellView.active.index
      names[lref.layer_index] = lref.name
    end
  end
  
  puts "Non-empty layers of cell #{cell.name} (including subcells):"
  layers.each do |layer,datatype,li|
    if ! cell.bbox_per_layer(li).empty?
      if names[li]
        puts "  #{layer}/#{datatype} [" + names[li] + "]"
      else
        puts "  #{layer}/#{datatype} (unnamed)"
      end
    end
  end
