This example describes how to add multiple GDSII files to one output file in batch mode on Windows.
In this example we will add two GDSII files to one output file. We will also offset the second file so the two won't overlap.

The script

We will use two sample files called page2_out.gds and page3_out.gds - The output will be saved under PAGE2_PAGE3.gds.

Syntax

C:\wcad\Gdsfilt\gdsfilte.exe C:\junk\evaluations\tiff2gds\PAGE2_out.gds C:\junk\evaluations\tiff2gds\PAGE2_PAGE3.gds = -unixcmdline -add page3_out.gds -combine TOPCELL = -offset 0,0 60000,0

Description

The command line includes an offset for the second file of 60000,0 and no offset for the first file.
The = sign corresponds to the top structure. It simply instruct GDSFILT to process the top cell in each file.
We also recommend to look at the complete gdsfilt command line page.
