Klayout

* Enhancement: Compile option to use libcurl instead of QtNetwork
This workaround enables builds on the native CentOS6
configuration with the package manager functional.
* Enhancement: Pass label (text) layers through DRC script
The "labels" method now allows copying labels from a layer
to the output.
* Enhancement: New "split" method for polygons
This method will fragment the polygons into two or more
smaller parts for reducing their vertex count.
* Enhancement: New "dtrans" method for RecursiveShapeIterator
This method delivers the transformation in micron unit space
* Enhancement: New "insert" methods for Shapes
Shapes can now insert from another Shapes container and
from a RecursiveShapeIterator. Possible applications are
fast flattening and fast region selection.
* Enhancement: New method to generate RDB items from shapes
RdbItemadd_value from a shape, RdbDatabasecreate_items
from a shapes container or recursive shape iterator and
RdbDatabasecreate_item from a shape.
* Enhancement: DXF and CIF "keep layer names"
If this option is set in the reader options, layer names
are not translated into GDS layer/datatype pairs.
Specifically a layer called "L5" for example is not
translated to 5/0 and to "L5D0" on output correspondingly.
The buddy script option is "--keep-layer-names".
* Enhancement: DXF contour joining accuracy
On the DXF reader's options, a contour joining accuracy
can be specified. Small gaps smaller than this accuracy
will be closed when forming joined contours from edges.
The buddy script option is --dxf-contour-accuracy=value.
* Bugfix: DXF display issue
In some cases, DXF cell instances did not trigger bounding
box update and the cells only got visible after save and
load.
* Bugfix: XOR progress is more realistic
The progress is updated after the layer has been computed,
not before.
* Bugfix: %GITHUB%/issues/117
DTransitype was broken.
* Bugfix: %GITHUB%/issues/116
Fixed a polygon decomposition bug when writing GDS files
with big polygons with many holes. As a side effect, the
polygons with many holes computed by a NOT operation for
example are less complex and spikes in the cutlines are
avoided.
* Bugfix: %GITHUB%/issues/115
Reader options were not persisted.
* Bugfix: %GITHUB%/issues/114
Custom line styles not loaded from tech's layer properties
file.
* Enhancement: %GITHUB%/issues/113
The XOR tool has an option now to heal result shapes which
cross tile boundaries. The result shape count of tiled
and non-tiled mode should basically be the same then.
* Bugfix: %GITHUB%/issues/112
Salt package repository relative paths have not been working.
* Bugfix: %GITHUB%/issues/109
Issues with Python 3 and shape properties - property
* Bugfix: %GITHUB%/issues/108
Bugfix on Boxenlarge and Boxmoved for empty boxes.
keys generated with Python 3 could not be written to GDS2.
* Bugfix: %GITHUB%/issues/107
Undo not working with shapes.
* Enhancement: %GITHUB%/issues/106
Search & replace help page enhancements.

* Bugfix: %GITHUB%/issues/90
DRC: "extended" was not working as expected with "joined = true"
* Bugfix: %GITHUB%/issues/89
Display issue on MacOS fixed
* Enhancement: %GITHUB%/issues/85
IDE debugger: files can be excluded from showing exceptions when
they are thrown. To exclude a file press the new "Ignore" button
when the debugger tells you an exception has been generated.
To re-able exception reporting, clear the list of the files
in the IDE settings ("Debugging" tab)
The macro IDE settings can now be edited in the File/Setup
dialog.
* Bugfix: %GITHUB%/issues/94
Retina displays are support to some extend on MacOS.
An open topic is the quality of the icons.
* Enhancement: build system for MacOS

* Enhancements: build compatibility with MacOS and Qt 5.9.
Qt 4.6 supported now as well with one restriction:
the package installation feature is not working.
* Bugfixs: Package manager

* Enhancement: Menu customization
Menu items can be disabled or enabled now. The former
"Key Bindings" configuration page has been turned into
"Menu Customization". Check boxes allow enabling or
disabling of menu items. Disabled menu items are not
shown.
A search filter allows quick selection of menu items
by title or path.
* Enhancement: The cell tree no longer is collapsed on edits
or when the sorting order changes.
* Enhancement: Using a special menu path, macros can be
configured to appear in submenus now.
* Enhancement: KLAYOUT_HOME environment variable to
control the location of the application folder.
The application folder is the place where KLayout
keeps the configuration, macros, packages and
other things.
* Enhancements: Major overhaul of the build environment
- Qt5 supported now
- Employs qmake as build system
- Reorganisation of the sources
- Continuous integration enabled (unit tests
integrated in .pro files, JUnit output etc.)
- Compatible with the clang compiler
* Enhancements: Buddy tools: KLayout now comes with a set of
additional executables that provide some functionality
subset in a lean way. These binaries are named "strm..."
and are installed along with KLayout.
- strm2cif: converts any format to CIF
- strm2dxf: converts any format to DXF
- strm2gds: converts any format to GDS2
- strm2gdstxt: converts any format to GDS2/text
- strm2oas: converts any format to OASIS
- strm2txt: converts any format to plain text (internally)
- strmclip: creates a clip from a file
- strmcmp: compares two files (logically)
- strmxor: compares two files (geometrically)
For more information, use the "-h" or "--help" option.
* Enhancements: HTTPS support for loading files from URL's directly
* Enhancements: Numerous enhancements and optimizations in the RBA/pya
area and in the debugger.
* Enhancements: KLayout notifies the user when a file was changed and
asks whether to reload.
* Enhancements: "File cell or layer": type into the cell or layer list to jump to the
cell name typed.
* Enhancements: Advanced search features in the filter entry box
for the cell selection form: Case sensitive/insensitive,
glob pattern, clear button.
* Enhancements: Tree expansion icons have a better contrast now on Windows
with dark background.
* Enhancements: Forward and backward navigation buttons in the main window.
These buttons jump to the previous or next display state:
zoom window, hierarchy depth, etc..
* Enhancements: A Package manager is provided. Packages are add-ons for
KLayout and can include macros, script libraries, fonts
for the TEXT PCell, technologies, DRC scripts etc.
Packages can be published on GitHub or any server
supporting WebDAV. After registering a package, users
can install or update packages with a few clicks.
For more information see %GITHUB%/wiki
or "About Packages" in the "Various Topics" area of the main
documentation. The package manager is found in the "Tools"
menu under "Manage Packages".
* Enhancements: LEF/DEF reader:
- Compatibility fixes with version 5.8
- Regions and Groups are supported now
- LEF/DEF is a standare format now and
can be used with "File/Open" for example.
* Enhancement: DXR reader supports variable path widths now
* Enhancement: XOR provides graphical progress
* Enhancements: Libraries can be associated with a technology. Only libraries
associated with the selected technology are shown in the selection
dialog.
* Enhancements: Overlapping instances are easier to select now (instance
selection cycling).
* Enhancements: Many more methods in RBA/pya. For example:
- Ability to directly insert "D" types (such as DBox
into layouts and cells.
- RBA::RecursiveShapeIterator now supports complex (non-rectangular)
search regions
- A more consistent type framework (consistent complex transformation
types, vectors)
- More intuitive interface in certain objects (i.e. CellView,
LayerPropertiesNode, Annotation etc.). Changing an attribute
usually has an immediate effect on the respective property now
("live objects")
- Hash functions for certain objects - Box, Edge, Trans, Polygon,
and other objects can be used as dictionary keys now.
- New import methods for Region, EdgePairs and Edges
- New features for LayerMapping and CellMapping
- Multiple selected cells in LayoutView
- RBA::TextGenerator to supply the Basic.TEXT PCell's
functionality as static feature
- Receivers can be added to signals and removed from
signals now.
- Individual instance iterator for CellInstArray
- ...
* Enhancements: Enhanced layout statistics form with detailed shape
statistics.
* Enhancements: Line styles (dashed, dotted etc.) available now.
Works best with manhattan layouts.
* Enhancements: "Marked box mode": boxes are drawn with a cross.
* Enhancements: Arbitrary pattern size for custom fill pattern (no
limited to multiples of 8). Max size is 32x32.
Enhanced annotations:
- Ellipses
- Position markers
- Text alignment
- "Auto measure" rulers (place a ruler measuring the
distances between adjacent objects with a single
click)
* Enhancements: DRC enhancements:
- Text support
- "smoothed" function
- "layers" function delivers all layers read
- Polygon with edge interactions
- middle and extent_refs methods for center point and other
references
- "corners" function
- "collect...", "select" and "each" methods
* Enhancements: GDS2 paths can now use the MultiXY extension too.
* Enhancements: X2 Support for Gerber import.
* Enhancements: A function to reset the window state after the
window has been misconfigured (i.e. detaching or closing
the dockable windows). This feature is found in
View/Restore Window.

* Enhancements: New method CellViewis_dirty?
This method indicates that a cell view needs saving
* Bugfix: DEF reader was not able to read routing
Routed segments with vias plus continued wiring
were not read. Instead an error message was shown
saying "Invalid orientation specification"
* Bugfix: Setting "technology-data" configuration property did not work
Reading or writing the "technology-data" configuration
property is the only way to access technology data from
a script. Hence it's important that this property can
be set. With this patch, "technology-data" can be set
to an XML string which has the same format than the
one stored within the configuration file.
* Bugfix: Reader issues with some RVE files
The RVE reader could not read files with cell names
containing hyphens (like "A-B").
* Bugfix: Inplace operators are now working in Python too
For example "r1 += r2" was not working where r1 and r2
were pya.Region objects.

* Enhancements: The RBA::Regionsmooth function was enhanced to
give somewhat better results
* Enhancements: DXF's circle approximation can now also specified
through an "accuracy" parameter: if less than the number of
specified points is required to achieve the given accuracy, the
number is reduced accordingly. This also applies to the polygon
interpolation of spline and arc curves.
* Enhancement: RBA integration now is compatible with Ruby 2.3
which allows building on Ubuntu 16 as well.
* Enhancement: OASIS files with instance angles >360 were rejected
before. Now, this has turned into a warning.
* Bugfix: DEF reader was failing to read MASK/via combinations.
* Bugfix: The marker browser's "show only rules with errors" option
was enabled again on sorting of errors.
* Bugfix: Using Layout objects for inputs didn't work
* Bugfix: Copying Hierarchy treets containing PCell's made the
PCell's being turned into static cells.
