Masque README

Masque is a Python module for designing lithography masks.

The general idea is to implement something resembling the GDSII file-format, but with some vectorized element types (eg. circles, not just polygons) and the ability to output to multiple formats.

Installation

Requirements:

  • python >= 3.8
  • numpy
  • klamath (optional, used for gdsii i/o)
  • matplotlib (optional, used for visualization functions and text)
  • ezdxf (optional, used for dxf i/o)
  • fatamorgana (optional, used for oasis i/o)
  • svgwrite (optional, used for svg output)
  • freetype (optional, used for text)

Install with pip:

pip3 install 'masque[visualization,oasis,dxf,svg,text]'

Alternatively, install from git

pip3 install git+https://mpxd.net/code/jan/masque.git@release

Translation

  • Pattern: OASIS or GDS "Cell", DXF "Block"
  • Ref: GDS "AREF/SREF", OASIS "Placement"
  • Shape: OASIS or GDS "Geometry element", DXF "LWPolyline" or "Polyline"
  • repetition: OASIS "repetition". GDS "AREF" is a Ref combined with a Grid repetition.
  • Label: OASIS, GDS, DXF "Text".
  • annotation: OASIS or GDS "property"

TODO

  • Better interface for polygon operations (e.g. with pyclipper)
    • de-embedding
    • boolean ops
  • Deal with shape repetitions for dxf, svg
  • Maybe lib.create(bname) -> (name, pat)
  • Schematic:
    • Simple cell:
      • Assumes no internal hierarchy, or only other simple hierarchy
      • Return pattern, refer to it by a well-known name
    • Parametrized cell:
      • Take in lib
      • lib.create(), and return a string
      • Can have pcell hierarchy inside
