Cell iteration within a script

stockstephanie

I am currently building out a LEF extractor script that works pretty well per cell, I just need a little extra help to iterate over cells. I was wanting to make a list of standard cells that I could iterate over to write to one file all at once for all the cells that I want in a "library" view, but I haven't found a function yet that will let me call a cell view by name. I very likely just missed it, but is there a way to essentially call:

cv = RBA::LayoutView.current
raise "No active layout" if cv.nil?
cell = cv.cell("AND2_1X") # cell   = cv.active_cellview.cell

instead of using the active_cellview function?
Thanks!

Hello,

Iteration is straightforward:

1) Iterate over all cells of a layout: layout.each_cell:

2) Iterate over all (called) cells inside a cell: cell.called_cells.each:

Cheers,
