How to draw labelled alignment marks?

  Hi Hossein,

  The code below will generate the labels in a new cell called "ALL_LABELS". The size of the text is defined by the "magnification" variable.

  Cheers,

  Tomas

  module MyMacro
  
    include RBA
  
  # User input ---------------------------------------------------------------------
  
  layer = RBA::LayerInfo::new(1, 0)
  numberX = 100
  pitchX = 150.0
  numberY = 100
  pitchY = 150
  
  magnification = 10.0
  orientation = RBA::DTrans::R0
  
  #------------------------------------------------------------------------------------
  
  
  
  
  # select the layout of the current cellview
  main_window =  RBA::Application::instance.main_window
  layoutview = main_window.current_view
  layout = layoutview.active_cellview.layout
  
  # add a cell (in this case "ALL_LABELS")
  cell_index = layout.add_cell("ALL_LABELS")
  cell = layout.cell(cell_index)
  
  # find the lib
   lib = RBA::Library.library_by_name("Basic")
   lib || raise("Unknown lib 'Basic'")
  
  # find the pcell
   pcell_decl = lib.layout.pcell_declaration("TEXT")
   pcell_decl || raise("Unknown PCell 'TEXT'")
  
   #------------------------------------------------------------------------------------
  
  # create TEXT instances
  
  for i in 1..numberX do
  
    for j in 1..numberY do
  
        x = (i-1) * pitchX
  
        y = (j-1) * pitchY
  
        text = i.to_s.rjust(3, "0") + "." +  j.to_s.rjust(3, "0")
  
        # set the parameters
         param = { "text" => text, "layer" => layer, "mag" => magnification }
  
         # build a param array using the param hash as a source
         pv = pcell_decl.get_parameters.collect do |p|
         param[p.name] || p.default
         end
  
         # create a PCell variant cell
         pcell_var = layout.add_pcell_variant(lib, pcell_decl.id, pv)
  
         # instantiate that cell
         t = RBA::DTrans::new(orientation, x, y)
         cell.insert(RBA::DCellInstArray::new(pcell_var, t))
  
    end
  
  end
  
  #------------------------------------------------------------------------------------
  
  layoutview.add_missing_layers
  
  end

  Hi Thomas,

  thanks for the code :-)

  It's still possible however, just to draw manually ... just place a "TEXT" PCell from the "Basic" library, go to the "PCell" tab in the instance properties and enter the layer and text you want to see.

  Thank you so much Thomas and Matthias. This was exactly what I needed.
