  Hi!

  I think you should look make loop over each cell in layout (Layout.each_cell) and then use Cell.bbox. See documentation and similar code as example.

  Hi Eugenne,
  Thanks for your answer , but I can't work it into my Klayout.
  I can using(make code) for DRC or Ruby just a little , but I can't code Python....
  do you have another ways to do that?

  Hi!

  Ruby API is almost same as Python. Most importang thing is to know classes and their methods as well as context of their usage. Python example could serve this purpose :-) You could try to search this forum for Ruby examples of same API.

  Quick and Dirty use at your own risk

  
  from pya import *
  import numpy as np
  import csv
  
  # Enter your Python code here
  mw = pya.Application.instance().main_window()
  layout = pya.Application.instance().main_window().current_view().active_cellview().layout() 
  topcell = pya.Application.instance().main_window().current_view().active_cellview().cell
  lv = pya.Application.instance().main_window().current_view()
  
  if lv == None:
    raise Exception("No view selected")
  
  if layout == None:
    raise Exception("No layout")
  
  cv = pya.Application.instance().main_window().current_view().active_cellview()
  dbu =layout.dbu
  
  cell = pya.Application.instance().main_window().current_view().active_cellview().cell
  if cell == None:
    raise Exception("No cell")
  cstr = "Cells Found"
  
  lv.transaction("Undo Selection") 
  
  #Select All in Cells in Layout and Parse cellname and X,Y coords
  mw.menu().action("edit_menu.select_menu.select_all").trigger()
  
  coords = []
  tc = "Topcell"+","+topcell.name
  sc  = "SubCell"+","+ "X " +","+"Y"
  coords.append([tc])
  coords.append([sc])
  for sel in lv.each_object_selected():
        if sel:
          if sel.is_cell_inst():
            inst = sel.inst()
            name = inst.cell.name
           #get the X/Y coordinates of the Instance
            pX = inst.cplx_trans.disp.x * dbu
            pY = inst.cplx_trans.disp.y * dbu
            nxy = name+","+str(pX)+","+str(pY)
            coords.append([nxy])
  
  #Print to the Console
  print (cstr.center(40, '#'))  
  np = np.asarray(coords)             
  print(np)
  print (cstr.center(40, '#'))
  
  csv.register_dialect('myDialect',
  delimiter = '|',
  quoting=csv.QUOTE_NONE,
  skipinitialspace=False)
  
  #Name this as you want and Export to a CSV file
  tcs = "E:\\Klayout\\CSV\\" + topcell.name + ".csv"
  with open(tcs, 'w', newline='') as f:
      writer = csv.writer(f, dialect='myDialect')
      for row in np:
         writer.writerow(row)
  f.close()
  
  #Unselects all Instances
  mw.menu().action("edit_menu.select_menu.unselect_all").trigger()
  lv.commit()

  Hello,

  I use this one for my wafer maps and chip floorplans:

  module MyMacro
  
  
    app = RBA::Application.instance
    mw = app.main_window
    lv = mw.current_view
    cv = lv.active_cellview
  
    if lv == nil
  
      raise "No view selected"
  
    end # if
  
    if !cv.is_valid?
  
      raise "No cell or no layout found"
  
    end # if
  
    # Ask for the file name
  
    filename = RBA::FileDialog.get_save_file_name("Flat Dump", ".", "CSV files (*.csv);; All files (*)")
  
    if filename.has_value?
  
      File.open(filename.value, "w") do |file|
  
        file.puts("Instance,X-coord,Y-coord,Rotation")
  
          cv.cell.each_inst do |inst|
  
                  iindex = inst.cell_index
                  name = cv.layout.cell_name(iindex)
                  itrans = inst.trans.to_s.gsub(",", "\s").split("\s")
                  instrot = itrans[0]
                  instx = (itrans[1].to_i * cv.layout.dbu).round(6)
                  insty = (itrans[2].to_i * cv.layout.dbu).round(6)
  
              if inst.is_regular_array?
  
                  na = inst.na
                  nb = inst.nb
                  a = inst.a * cv.layout.dbu
                  b = inst.b * cv.layout.dbu
  
                  (0..(na-1)).each do |ia|
  
                    (0..(nb-1)).each do |ib|
  
                      instx2 = (instx + ia * a.x + ib * b.x).round(6)
                      insty2 = (insty + ia * a.y + ib * b.y).round(6)
  
                      file.puts("#{name},#{instx2},#{insty2},#{instrot}")
  
                    end # each
  
                  end # each
  
              else
  
                  file.puts("#{name},#{instx},#{insty},#{instrot}")
  
              end # if
  
          end # each_inst  
  
      end # File.open
  
    end # if
  
  
  end # MyMacro
  

  Cheers,
