masque 2D CAD library
|
|
|
|
masque is an attempt to make a relatively compact 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
|
|
`Ref`).
|
|
|
|
`Ref` 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, often they are left
|
|
empty for superclasses and it is the subclass's responsibility to set them correctly.
|
|
- File I/O submodules are not imported by `masque.file` to avoid creating hard dependencies
|
|
on external file-format reader/writers
|
|
- Try to accept the broadest-possible inputs: e.g., don't demand an `ILibraryView` if you
|
|
can accept a `Mapping[str, Pattern]` and wrap it in a `LibraryView` internally.
