Insert the text on batch mode

Canny

Hi, Matthias,

The function of text dump to file is a convenient tool
If it is possible to insert the text on batch mode with klayout?

For example, user prepares text file of the texts and corresponding coordinates as following,
#contents,x,y
A,0.00,0.00
A,5.00,10.00
A,4603,4135
A,4603,4137
A,4603,4139
A,4603,4142

Then use the batch command insert these texts into the layout file

Hi Canny,

that is basically easy. Here's the script core:

# The layer where to put the texts to
layer = RBA::LayerInfo::new(1, 0)

# The file where to take the texts from
input_file = "texts.txt"

lv = RBA::Application.instance.main_window.current_view
lv || raise("No view open")
ly = lv.active_cellview.layout
cell = lv.active_cellview.cell

layer_index = ly.layer_indices.find { |li| ly.get_info(li).is_equivalent?(layer) }
layer_index || raise("Layer not found: #{layer.to_s}")

File.open("texts.txt") do |file|
  file.each_line do |line|
    if line.sub(/#.*$/, "") =~ /^\s*(.*)\s*,\s*(.*)\s*,\s*(.*)\s*$/
      string = $1
      # assume the coordinates are micron units
      x = ($2.to_f / ly.dbu + 0.5).floor
      y = ($3.to_f / ly.dbu + 0.5).floor
      cell.shapes(layer_index).insert(RBA::Text::new(string, RBA::Trans::new(x, y)))
    end
  end
end

It's lacking user interface and you have to edit file name and target layer, but you can simply put it into a macro in the macro IDE and run it inside the editor.

Best regards,

Hi, Matthias,

It works very well and save lots of effort to give texts on gds file.
Thank you.
