Ruby scripting- print an image of a single die with pad details from a csv file

raji

Hi,
I wrote a program to find distance between pads for probing purpose. After finding the distance, I am saving it in a csv file.
My ultimate aim is to print an image of a single die with pad info. I would like to know how to take the image using script and write pad info from csv file to the image. Any help is appreciated
Inputs given are position of the pad and also whether it is simple pad or complex pad.
One is simple pad and 2 is complex pad

 module DimPads
include RBA
$VERBOSE = nil
myListx = []
myListy = []
c=[]
c1=[]
pad_pos= RBA::InputDialog.get_item("Pads position", "Position", ["North", "South", "East", "West"], 1)
val= RBA::InputDialog.get_int_ex("Input pad details", "Select 1 for simple pads 2 for complex:", 2 , 1, 2, 1)
value=val.value
pos=pad_pos.value

outfile = "C:/fullpath/PadsDim.csv"
file = File.open(outfile, "a")
#file.puts("pos,pad dimension") # Header row

ly = CellView::active.layout
lv = Application::instance.main_window.current_view|| raise("No layout loaded")
lv.each_object_selected {
  |obj|
  shape = obj.shape
  if shape.is_polygon?||shape.is_box?
    # NOTE "transformed" - this transforms the polygon into the current cell
    shape.polygon.transformed(obj.trans).each_point_hull { 
      |pt|     
      (x, y) = pt.x*ly.dbu, pt.y*ly.dbu
      myListx << x
      myListy << y

    }
  end
}

Hi, Raji!

I think you need to create text labels in layout (see Layout, Shape (how to add) and LayerProperties (how to make layer visible)) and than use LayoutView.save_image or LayoutView.save_image_with_options.

@raji There is little to add to Eugene's summary. Your assignment is pretty unspecific. What does "print" mean? If a PNG screenshot is sufficient, then the job is to populate a LayoutView with the proper objects and then generate an image using "save_image" or "save_image_with_options". You may also consider using annotations (rulers) as additional, non-layout objects.

You may want to study the code I am using to generate the DRC sample images. It's a similar task and the script can be found here: https://github.com/KLayout/klayout/blob/master/scripts/create_drc_samples.rb
