Welcome to python-gdsii's documentation!
|
|
========================================
|
|
|
|
`python-gdsii` is a library that can be used to read, create, modify and save
|
|
GDSII files. It supports both low-level record I/O and high level interface to
|
|
GDSII libraries (databases), structures, and elements.
|
|
|
|
This package also includes scripts that can be used to convert binary GDS file
|
|
to a simple text format (`gds2txt`), YAML (`gds2yaml`), and from text format
|
|
back to GDSII (`txt2gds`).

Usage
|
|
-----
|
|
|
|
For most cases interface provided by Library class from gdsii.library should be
|
|
enough. Here is a small example::
|
|
|
|
from gdsii.library import Library
|
|
from gdsii.elements import *
|
|
|
|
# read a library from a file
|
|
with open('file.gds', 'rb') as stream:
|
|
lib = Library.load(stream)
|
|
|
|
# let's move the first structure to a new library
|
|
new_lib = Library(5, b'NEWLIB.DB', 1e-9, 0.001)
|
|
struc = lib.pop(0) # libraries and structures are derived from list class
|
|
new_lib.append(struc)
|
|
|
|
# let's also add some elements...
|
|
# Note: first and last points in the boundary should be the same
|
|
# this is required by GDSII spec.
|
|
struc.append(Boundary(45, 0, [(-100000, -100000), (-100000, 0), (0,0), (0, -100000), (-100000, -100000)]))
|
|
|
|
# Save both files with different names...
|
|
with open('newfile1.gds', 'wb') as stream:
|
|
lib.save(stream)
|
|
|
|
with open('newfile2.gds', 'wb') as stream:
|
|
new_lib.save(stream)
|
