Texts are not only kept inside original layers, but
also inside deep layers. This enables using texts
from DRC.
However, texts in deep layers are kept as markers.
Mostly they are converted back to texts, but the
orientation will be lost.
The change eliminates the need to using Iterators
in DRC instead of original layers and use of
label layers in deep mode.
A drawback is the presence of marker shapes in
deep mode (unless polygon layers are created).
Also, text output to RDB is not supported from
deep layers currently.
Refactoring:
* more consistent behavior of output redirection
* ut library was refactored and split into several
.h/.cc
* concept of long runners introduced
* long runners can be skipped with "test_is_long_runner()"
* same for editable/non-editable mode tests
- modified definition of texts with the ability to produce
point-like edge objects
- middle and extent_refs methods for center point and other
references.
RBA now provides a hash method for Box, Edge, EdgePair, Trans,
Polygon, SimplePolygon, CellInstArray, LayerInfo, Path, Text,
Point and Vector.
eql? is mapped to ==.
==, != and < act "fuzzy" for the double-typed variants.
Hence, these objects can be used as hash keys now.
- A new constructor for RBA::Region has been provided to
create text markers from a shape iterator
- The DRC framework has been enhanced with a "text" function
