The aim of this rework was to enable PCell implementations
that use the basic methods rather than the "_impl" variants.
For the latter, potential variable name clashes happen when
parameters are called "cell", "layout", "layer" or similar.
New methods enable implementation on the level of the
non-"impl" methods. For example:
def produce(self, layout, layers, parameters, cell):
self.init_values(parameters, layers)
...
self.finish()
This commit
- Ignores exceptions when checking for PCells that accept shapes.
Hence a single rogue one does not break the feature.
- Prevents errors when parameters named "layer" are present
by making the implementation safe against this case.
- In addition, guiding shape parameters of type "Path", "Box" etc.
(i.e. integer types) are supported too although they are
not recommended for portability.
The issue is with "dllexport": previously, dllexport was present on
exposed templates tool (= visibility(default) for gcc/clang). This
ensured MacOS compatibility since then the typeinfo is corretly
shared and dynamic_cast/typeid works.
For Windows, the "dllexport" equivalent requires the template
instantiations to be declared "external" which is a coding nightmare.
The solution is to provide separate macros for real (non-specialized,
not explicitly instantiated) templates (.._PUBLIC_TEMPLATE) which
is defined as empty for Windows and "visiblity(default)" for gcc/clang.
1.) Startup issue:
This is solved by making sure templates with virtual functions
are made visible in the DSO. This way, dynamic_cast is possible
across DSO's.
Scary: clang/MacOS wants the forward declarations be declared visible as well.
2.) Menu issue:
The best solution is to have only one QMenuBar. The navigator
now gets a synthetic menu bar composed of QToolButtons.
The LLVM STL implementation does not recognize "typedef void iterator_traits"
as dummy declaration. It will fall back to an empty traits struct.
Using the default "forward_iterator_tag" for the iterator_traits solves
this compile issue.
This commit adds "permissive" mode to OASIS writer to allow
odd-width paths (which are rounded).
This commit contains in addition:
* The check for odd-width paths is done post-scaling, so
reducing the DBU is a workaround
* Unit tests for the RBA binding of SaveLayoutOptions
* Documentation updates on some SaveLayoutOptions attributes
* Using Ruby predicate notation for cif_blank_separator?
(note question mark) for consistency. The old notation is
still there but deprecated
* --permissive option on buddies command lines where applicable
Reason: PCellDeclaration::parameter_declaration is volatile when
the PCell does not want parameter declaration caching. In this
case, begin .. end iterators must not be taken from different
calls to parameter_declaration for example.
* Moved tlSystemPaths into lay namespace where it belongs
* Doc updates
* New command line switch -y and -yd for unattended installation
* Download URL's can be relative to salt.mine URL
* KLAYOUT_HOME environment variable to make ~/.klayout configurable
* Better error messages on XML parser on file/stream read errors
(specifically from http/https)
This is how to reproduce the bug: have a layout with two
layers. Select two shapes of different layers and delete them.
One layer is not updated and only after zooming/panning the
shape will disappear on this layer.
* Modification of the mapping is possible now
(#map used to ignore mappings if there was one
already)
* Added DropCell mapping (also for RBA)
* Added unit tests for cell mapping, layer mapping
db::merge_layouts, db::copy_shapes and db::move_shapes
* ut framework now has a text file compare
* Added tests for strm2txt, strmclip and strmcmp
* Fixed the output of the PrintingDiffReceiver in some cases
* Cell renaming does not give a difference in smart cell mapping mode
The goal of the refactoring is to support unit tests
for the db library.
For this, a distributed unit test concept has been
introduced (later to be extended to other libs).
Unit tests are shared objects called ".ut" and are
automatically loaded by the ut runner. The bd library
now has two folders - one for sources and one for the
unit tests. The sources are separated into lib and apps.
First unit tests for the writer options have been
provided.
* Generalized Polygon to edge interaction into db::Polygon tools
* Added tests for this
* Equipped region to edges interaction with this feature to
reduce random test fails
* Multiple (reproducible) seeds for Region tests
* More tolerances for TilingProcessor tests
* ICplxTrans is_unity? implementation is using proper
double tolerances now
* File watcher tests wait longer to allow for slow
response on loaded Windows build server
- Allow full 32bit for box width and height
and some other properties (for border case
testing - not recommended)
- Reduce arrays with step distance 0 to
dimension 1 - avoids overlapping instances
or shapes.
Bug: sometimes, if the files had different database units, the XOR
tool was showing differences while there are none.
This was due to a sloppy computation of the tile boxes. The solution
is to properly round the tile size to a common database unit and
to use a common effective size for both inputs.
Region: insert of other regions, shape collections (with transformation)
Edges: insert of other edge collections, regions, shape collections (with transformation)
EdgePairs: insert of other edge pair collections
- modified definition of texts with the ability to produce
point-like edge objects
- middle and extent_refs methods for center point and other
references.
With this fix, regions can be interaction-tested with edge collections.
Only "normal" interaction is available - select_overlapping is not. This
is still confined to region to region interactions.
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
The double types (DCoord, DPoint, DVector ...) support a
more consistent equivalence criterion now. This supports
micron-unit objects without loss of precision.
Before this fix, the precision used for 0.01 which was
basically implying a resolution of 10nm for micrometer-unit
double objects.
Libraries now carry a technology association and
only libraries associated with the current technology
can be selected.
To enforce proper update, cancel() will be used upon
change of technology. This avoids side effects when
changing the technology without notifying the library
selection widgets.
The MainWindow::cancel method has been generalized to
cover the functionality of cm_cancel without the
exception handling.
This enables font packages: packages can now provide fonts by
featuring a "fonts" directory with the font layouts.
This commit also adds the capability to dynamically add fonts.
The Glyphs system is decoupled from the application's system
path and the BASIC.TEXT PCell parameters are non-cached to
enable dynamic updates.
The effect was: when drawing a shape on a single layer, all
layers have been redrawn. This was changed such that only
the affected layer is actually redrawn.
* Refactoring: no more "box+exclude" regions - they
can be emulated using a NOT with the same result
* "confinement" of regions inside recursive shape
iterators
* setters and getters for complex regions in GSI,
confinement
* more unit tests, some bug fixes
- Added some tests
- Performance improvements for insert of
regions into shapes
- Added LayoutLocker for that purpose
(locks a layout against updates temporarily)
- Improved implementation on RecursiveShapeIterator
with complex regions: will now check if a shape
is really inside the region.
