Array of rectangle in Parray

soumeniit

Hello,

I'm very new to Python language and KLayout. For a project, I need to generate a series of rectangles (each in the same or different layers) in KLayout using Macro development. This way, depending on the input/variable assignment from the user, say N, the program can generate N Rectangles and height and width can be adjusted for one rectangle and others will increase or decrease by a magnification factor. Pitch can be adjusted too. Please help me with this. A picture is added here.

This script does what you want. You need to edit the parameters to your liking:

import pya

N = 4

view = pya.Application.instance().main_window().current_view()
layout = view.cellview(0).layout() # You do not need this for this scrip...
cell = view.cellview(0).cell

for n in range(N):
    b = pya.DBox(pya.Point(n+0,n+0), pya.DPoint(10+2*n, 10+2*n))
    cell.shapes(0).insert(b)

Hi @soumeniit,

Thanks for your interesting post.

Your requirements do not seem simple to me, especially when all conditions are combined.
If I were you, I would divide the problem into two components (divide-and-conquer approach):
(1) design description captured in an Excel sheet or a similar (I prefer CSV)
(2) manipulation of the design description by KLayout (macro)

Please refer to the attached file set that conveys my idea.
To be honest, I borrowed the idea from this post.

I hope the Python code is self-explanatory.
However, you need to carefully read the KLayout document (the built-in Assistance tool is handy).
More specifically, the following Classes are crucial:
(1) Layout
(2) Cell
(3) DBox
(4) LayerInfo
(5) MainWindow
(6) LayoutView

You can easily find various information and tutorials on Pandas.

Good luck!
