How to write a GDS with some of layers

jiunnweiyeh

Hi sir,
I just want to save some of layers into GDSII file
I knew that should using add_layer in the option of write command like below ,
But it is not workable.
Could you please let me know what is error in my code?
Thanks.

mw = RBA::Application::instance.main_window
mw.layout
view = mw.current_view

layoutfile = RBA::Application::instance.main_window.current_view.active_cellview.name
opt = RBA::SaveLayoutOptions::new
opt.format = "GDS2"
opt.keep_instances=true
opt.no_empty_cells=true
opt.gds2_max_vertex_count=4000
###################################################
ubm_index=0
layoutView = RBA::Application::instance.main_window.current_view.active_cellview.layout
  layoutView.layer_indexes.each do |layer_index|
  layer_info = layoutView.get_info(layer_index)
  if layer_info.to_s.match("152/1") then
  puts "The #{layer_index} mapping to #{layer_info}"
  opt.add_layer(layout.layer(layer_index),layer_info)
  end
 end

 layout.write("3361277.gds",opt)

Hi jiunnweiyeh,

An additional opt.deselect_all_layers line before you loop through layers should solved the issue.
By default all layers are being selected during saving, you'll need to deselect them and add layers back like your example.

Hi @RawrRanger and @jiunnweiyeh,

That is correct, but actually the first "add_layer" would automatically imply "deselect_all_layers". So it is needed if the condition never matches. Maybe there is no layer "152/1" (or it is empty) in your case?

Hi @Matthias
151/1 is not empty layer , and I got thse error message...
base on this code.

layoutfile = RBA::Application::instance.main_window.current_view.active_cellview.name
layoutLibrary = RBA::Application::instance.main_window.current_view.active_cellview.filename
currentfilepath=layoutLibrary.sub(layoutfile,"")


layoutfile = RBA::Application::instance.main_window.current_view.active_cellview.name
opt = RBA::SaveLayoutOptions::new
opt.format = "GDS2"
opt.keep_instances=true
opt.no_empty_cells=true
opt.gds2_max_vertex_count=4000
opt.deselect_all_layers

 if layer_info.to_s.match("152/1") then
  opt.add_layer(layout.layer(layer_index),layer_info)
  end

Hi All,
I got the answer , the code should be change to

opt.add_layer((layer_index),layer_info)
