masque 2D CAD library
|
|
|
|
masque is an attempt to make a relatively small library for designing lithography
|
|
masks. The general idea is to implement something resembling the GDSII and OASIS file-formats,
|
|
but with some additional vectorized element types (eg. ellipses, not just polygons), and the
|
|
ability to interface with multiple file formats.
|
|
|
|
`Pattern` is a basic object containing a 2D lithography mask, composed of a list of `Shape`
|
|
objects, a list of `Label` objects, and a list of references to other `Patterns` (using
|
|
`SubPattern`).
|
|
|
|
`SubPattern` provides basic support for nesting `Pattern` objects within each other, by adding
|
|
offset, rotation, scaling, repetition, and other such properties to a Pattern reference.
|
|
|
|
Note that the methods for these classes try to avoid copying wherever possible, so unless
|
|
otherwise noted, assume that arguments are stored by-reference.
|
|
|
|
|
|
NOTES ON INTERNALS
|
|
==========================
|
|
- Many of `masque`'s classes make use of `__slots__` to make them faster / smaller.
|
|
Since `__slots__` doesn't play well with multiple inheritance, the `masque.utils.AutoSlots`
|
|
metaclass is used to auto-generate slots based on superclass type annotations.
|
|
- File I/O submodules are imported by `masque.file` to avoid creating hard dependencies on
|
|
external file-format reader/writers
