Automate copy and replace

sedborg2

how would automate copy cell and replace. I can do by hand but I would like to automate the copy from other window (full copy) then go to different window and replace the cell with the copied cells. I do this for multiple cells

That is not difficult but you need:

• The path to the first file (target)
• The path to the second file (source)
• A list of source and target cell names (where to copy from, where to copy to)
• The name of the output file

The script is:

# target
a = "target.gds"

# source
b = "source.gds"

# output file
out = "out.gds"

# cell names ( in_a, in_b )
# in_a cell from a is replaced by in_b cell from b
table = [
  ( "TO", "FROM" ),
  # more ...
]

ly_a = pya.Layout()
ly_a.read(a)

ly_b = pya.Layout()
ly_b.read(b)

for in_a, in_b in table:

  cell_a = ly_a.cell(in_a)
  cell_b = ly_b.cell(in_b)

  # remove everything from the target cell
  cell_a.prune_subcells()
  cell_a.clear()  

  # copy the source cell into the target cell
  cell_a.copy_tree(cell_b)


ly_a.write(out)
