Python code equivalent of converting all cells to static

Hi Matthias,

I am currently using the following code piece to convert all cells in a layout to static but it seems like it does not work properly. Do you think I am making a mistake in somewhere? I am trying to get the same effect as when I click Edit->Layout->Convert All Cells to Static.

Here is the code I use:

""""""

for cell in layout.each_cell():
layout.convert_cell_to_static(cell.cell_index())

"""""""

Thanks!

    Hello,

    The "convert_cell_to_static" method does not replace the cell - it will rather create a new, equivalent one. In order to replace all cells, you have first to create the static versions, then translate the instances and finally delete the original PCell variants:


    ly = pya.CellView.active().layout()

cells_converted = {}

# convert the cells
for cell in ly.each_cell():
  ci_org = cell.cell_index()
  ci = ly.convert_cell_to_static(ci_org)
  if ci != ci_org:
    cells_converted[ci_org] = ci    

# translate the instances
for cell in ly.each_cell():
  for inst in cell.each_inst():
    if inst.cell_index in cells_converted:
      inst.cell_index = cells_converted[inst.cell_index]

# delete the PCells
for ci in cells_converted:
  ly.delete_cell(ci)

    Regards,

    Matthias
