fatamorgana

fatamorgana is a Python package for reading and writing OASIS format layout files.

Homepage: https://mpxd.net/code/jan/fatamorgana

Capabilities:

This package is a work-in-progress and is largely untested -- it works for the tasks I usually use it for, but I can't guarantee I've even tried the features you happen to use! Use at your own risk!
Interfaces and datastructures are subject to change!
That said the following work for me:
- polygons
- layer info
- cell names
- compressed blocks
- basic property I/O

Installation

Dependencies:

python 3.5 or newer
(optional) numpy

Install with pip from PyPi (preferred):

pip install fatamorgana

Install directly from git repository:

pip install git+https://mpxd.net/code/jan/fatamorgana.git@release

Documentation

Most functions and classes are documented inline.

To read the inline help,

import fatamorgana
help(fatamorgana.OasisLayout)

The documentation is currently very sparse and I expect to improve it whenever possible!

Examples

Read an OASIS file and write it back out:

    import fatamorgana

    with open('test.oas', 'rb') as f:
        layout = fatamorgana.OasisLayout.read(f)
    
    with open('test_write.oas', 'wb') as f:
        layout.write(f)
