A simple layer processing scripting environment

Matthias

Recently I have received a request regarding automation capabilities for the layer processing functions (boolean operations, sizing and others). To provide a preliminary solution I have supplied a ruby script for download here: http://www.klayout.de/resources/layer_proc.rbm.

The script installs a new menu entry which allows to load and execute a processing script. The script can be used for implement layer generation and manipulation rules. Right now, the implementation is pretty simple and uses a flat approach, i.e. creates shapes in the top cell only.

You will find usage instructions in the script itself. Here is a short example which extracts the gate regions:

active = input("2/0")
poly = input("3/0")
gates = active.and(poly)
gates.output("10/0")

Since, the "and" method is available as the "*" operator, this example can be simplified to

(input("2/0") * input("3/0")).output("10/0")

To use these generation rules, save the script above as a text file and run the script using "Tools/Processing Scripts/Processing Script" to execute the script. To easily execute the script again, a list of most recently used scripts is maintained.

Hi Matthias,

I got an issue with shifting the layers in Klayout using the processing script. In the document I found the following command can be used to shift the layer by a given displacement.

l.shift(dx, dy) - Shift the layer by the given displacement.

But when I operate the following line in my code, it gave an error saying that "Ambiguous overload variants - multiple method declarations match arguments."

The command line I was using is as below:
input("210/0").shift(1,0).output("210/1")

Do you know what was the error ?

Regards,
Oscar

hello. I do not have access to the code link, could you please help?

This was 2011! The post is definitely outdated.

Please consider using DRC functions for that purpose. It's basically doing the same, but on a much higher level.
