* New: In Bootstrap, add cmake detection for libbfd.
* New: In Hurricane, in Backtrace, add BFD support to read debuginfo from
the shared libraries (aka DSO) when compiled with "-g". This avoid the
tedious step of running gdb after generating a core dump. It is also
mandatory in ExceptioWidget to known from where an exception was thrown
as Qt::notify() block all C++ exceptions.
Currently works only under Linux (gcc or clang), may be extended in
the future.
The BFD reading is based on the small utility from:
Don Hatch (hatch@plunk.org)
http://www.plunk.org/~hatch/goodies/backtracefilt.C
And small trinket: adjust the size of the window for high DPI screens.
* New: In CRL Core & Unicorn add link toward libbfd, if needed.
* Bug: In Anabatic:
- In _propagate(), on reaching a target, forgot to remove it from
the queue before pushing it back with the new distance. It also
simplificate the core algorithm as target as treated normal nodes.
* New: In Anabatic:
- Update cdebug to use the fastest macro version.
- More readable drawings of GCells and Edges.
- Added timer support.
- The distance is now computed in DbU::Unit (aka long) and not in
normalized float.
- The distance function is now a callback (std::function<>) that
can be changed (a default is provided at initialization).
- New concept of branch in the agglomerated connex component.
Each trace back part create a "branch" (tagged with a "branchId").
When a node is reached with the same distance, but from two
different branches, choose the the branch that was lastly created.
This create a slightly different tree which grows outward from
the newest branches.
- Makes the horizontal edges *slightly* longer than the vertical ones
to skew the tree to use vertical edges, as it is usually less
congested than the horiontal one (due to metal1 cell terminals).
It is also my understanding that it is useful to reduce the
number of vias, whithout introducing a via cost.
* New: In Bootstrap:
- Script sprof.py to perform sprof & demangle libraries execution
profile.
* ToDo: In Anabatic:
- Corner optimization. Sometimes when two corners are possible, the
wrong one is choosen. That is, one of it's edge cannot be used for
further grow of the tree.
* Change: In Hurricane Commons.h, even when cdebug print nothing, it slow
down the program (three times for Kite!). Create a macro cdebug_log
which calls cdebug *only* if the debug level is active.
* Bug: In Unicorn, in cgt.py, do not import Anabatic as it is not present
yet in the devel branch.
* Change: In Hurricane, in Commons.h, in the vector slot template, start
index at 0 and not 1 (to closer to the internal representation).
* Change: In ExtensionGo, forgotten trace system calls to update.
* Change: In Hurricane, in Flags add operator overload for "int" type
and not only "unsigned int". Otherwise the compiler complaints about
ambiguous overload when using enum values which are considered as
"int".
Simpler code for the BaseFlags::contains() method.
Added implicit conversion from BaseFlags toward bool type.
* Change: In Hurricane, in Commons, complete replacement of the previous
two trace systems (trace & ltrace) by a stream-based one.
As it is a true object it is much less fragile than the one based
on defines (but maybe a little slower).
Define a reservation table for the trace levels for all the
Coriolis & Chams components.
* Change: All tools, use the new trace system.
* Bug: In Hurricane, in HApplication, ExceptionWidget ans PyHurricane.h,
forgot to catch the Hurricane::Bug exception which was leading to
terminate() without explanations.
* Change: In Katabatic, In GCellTopology, now support one GCell with
five metal1 terminal of the same net. This unlikely configuration
did appear in the SNX for the first time...
* Test: post-receive hook on server should send mail [1].
* New: In VLSISAPD, in Parameter, callback have now a tag, which the
pointer to the caller. This allow for the callback removal when
the caller is destroyed.
* New: In VLSISAPD, in WidgetDescription, when associated to a parameter,
the destructor must remove the associated callback function on
the Parameter.
* New: In Hurricane, added JSON support for Configuration, separated
from vlsisapd, as the support is not available at this point.
JSON support for Configuration, Parameter & LayoutDescription.
* Change: In Hurricane, in JsonStack, the stack of JsonObjects has been
displaced here from HurricaneHandler. This way, all
JsonObject::toData() can access the JsonOjects in the context
of the parser.
* New: In Hurricane, in DBo::toJson() added support for Entity by
reference (ids).
* New: In Hurricane, added JSON support for all Layer sub-class types.
* New: In Hurricane, in Technology, export the Layers, but must be
sorted by increasing mask value.
* New: In Hurricane, in Entity, added support for Entity by reference (ids).
* New: In Hurricane, in DataBase, added technology full support.
* New: In Hurricane, In JsonNet, move the ring rebuild management from
JsonStack to JsonNet.
* New: In Hurricane, added JSON support for NetAlias, NetExternalcomponents
(not cleanly implemented as a Relation).
* New: In Hurricane, new method Cell::fromJson() to load a cell from
a JSON file.
* New: In Hurricane, In Graphics, make it an observable, for when JSON
fully reload the graphic state, it must be able to notify other
objects (namely the Controller).
* New: In Hurricane, in ControllerWidget, observe the Graphics to regenerate
the palette as needed. New method ControllerTab::graphicsUpdated().
* New: In Hurricane, in RawDrawingStyle added a destructor to release the
Qt pen/brush. Added JSON support for HSVr, DrawingStyle, DrawingGroup,
& DisplayStyle.
* New: In Hurricane, in GraphicsWidget, rewrite correctly the readGraphics()
to erase the previous widgets and re-create the new ones.
* New: In Hurricane, in PaletteWidget, correct re-creation of the layout/widgets
in case of Graphics change.
* New: In CRL Core, in System, register the parameters callbacks with
the address of the object, for later deletion.
* New: In CRL Core, in AllianceFramework, make it observable, to notify
library changes. For the AllianceFramework creation, now allow to
completly bypass the Python initialization system, when we expect
to restore it from a full blob. Added methods to sets the default
RoutingGauge & CellGauge.
* New: In CRL Core, added JSON suppport for CellGauge, RoutingLayerGauge
& RoutingGauge.
* New: In CRL Core, in LibraryManager, oberver AllianceFramework, to update
the list of libraries in case of change (for JSON full reload).
* New: In boostrap, in ccb.py, added support for the "support" project
which contains external dependencies. Currently contains only
RapidJSON. Those dependencies must be cloned here manually.
* New: In Hurricane, Initializer class for an ordered static initialization
across different compilation modules.
* Change: In Hurricane, at DataBase level, no longer save the Cells in
the libraries, but create and ordered list of Cell. Deepest cells
(leaf cells) first. To avoid dependency problems.
* New: In Hurricane, JSON support for Property.
* New; In CRL, added JSON support for AllianceFramework, Environement &
Catalog and their associated properties. Adjustment of the
AllianceLibrary creation policy.
* New: In Hurricane, added first support for DataBase native import/export
using JSON.
We choose RapidJSON, in SAX mode, to manage the JSON format low level
Read/Write. Thus, it's Git repository http://github.com/miloyip/rapidjson
must be added under ~/coriolis-2.x/src and manually build and installed
in the Coriolis installation tree (to be integrated in ccb later).
Two mode are being supported:
1. Cell mode: one Cell only is saved. In that mode, Entities
referred by Occurrences are "outside" the file. They are coded
through their "signature" (mostly, all the values of their
attributes). The ids saved in the file cannot be restored
identically as we cannot predict when and in which context the
Cell will be reloaded.
2. Design Blob mode: the whole design hierarchy, down and including
the standard cells is saved. This way the design is completly
self contained and Entities ared referred through their ids.
A design blob can only be loaded immediatly after starting cgt
as the DataBase *must* be empty. This way we restore the whole
design hierarchy with *exactly* the same ids.
Now, Hurricane object should provide a "toJson()" method for driving
JSON, and be associated with a JsonObject derived class for parsing.
* New: In Hurricane, ability to force the next id that will be used for a
DBo (used by Design Blob Mode).
* New: In Hurricane, in DataBase, added getCell() and getLibrary() functions
to allow the hierarchical access of a Cell/Library in native mode
(i.e. whithout the requirement of AllianceFramework).
* New: In Hurricane, In CellViewer, added menu entry for Save/Load of
JSON Design Blobs. Added at this level because we consider it as the
"native" format of Hurricane.
* New: In Unicorn, added support of import/export of JSON Cell.
* Bug: In Hurricane, in Instance, when cloning an Instance or uniquifying
it's master Cell, we forgot about the Occurrences (through shared pathes).
When an instance is cloned the Shared pathes still points toward the
original Instance. And when it's the master Cell that is uniquifyed
it's the Entities pointed to that remains in the original Cell.
This is a software design problem. It is difficult to define what
policy to adopt when uniquifying: basically that means that one
Occurence is either moved onto the clone or duplicated. Furthermore,
it is not trivial to known what Occurrence is pointing on the
uniquifyed/cloned item. Have to think about it a little more.
* Bug: In Etesian, in EtesianEngine, build the flattened nets and their
RoutingPads *after* uniquifying (through slaving bounding boxes).
This way we avoid the Occurrences problem described above.
* Bug: In Etesian, in EtesianEngine, invalidate the RoutingPad after
processing the placement so they are put into the right quadtree.
This problem is due to the fact that the RoutingPads do not belong
to the Instance that they refer. And when this instance is moved
around, she doesn't inform the RoutingPad that is has moved.
More software architecture design to review...
* Change: In Knik, in Vertex, add a "blocked" flag to signal disabled
vertexes in the grid (must not be used by the global router).
Modificate the Graph::getVertex() method so that when a vertex
is geometrically queried, if is a blocked one, return a non-blocked
neighbor. This mechanism is introduced to, at last, prevent the
global router to go *under* the pad in case of a commplete chip.
* New: In Katabatic, in AutoSegment, a new state has been added: "reduced".
A reduced segment is in the same layer as it's perpandiculars.
To be reduced, a segments has to be connected on source & target to
AutoContactTurn, both of the perpandiculars must be of the same layer
(below or above) and it's length must not exceed one pitch in the
perpandicular direction.
To reduce an AutoSegment, call ::reduce() and to revert the state,
call ::raise(). Two associated predicates are associated:
::canReduce() and ::mustRaise().
Note: No two adjacent segments can be reduced at the same time.
* Bug: In Katabatic, in GCellTopology, add a new method ::doRp_AccessPad()
to connect to the pads. Create wiring, fixed and non managed by
Katabatic, to connect the pad connector layer to the lowest routing
layers (depth 1 & 2). The former implementation was sometimes leading
to gaps (sheared contact) that *must not* occurs during the building
stage.
Remark: This bug did put under the light the fact that the initial
wiring must be created without gaps. Gaps are closed by making doglegs
on contacts. But this mechanism could only work when the database if
fully initialised (the cache is up to date). Otherwise various problems
arise, in the canonization process for example.
* New: In Katabatic, in AutoContactTerminal::getNativeConstraintBox(),
when anchored on a RoutingPad, now take account the potential rotation
of the Path's transformation. Here again, for the chip's pads.
* New: In Kite, support for reduced AutoSegment. TrackSegment associateds
to reduced AutoSegment are *not* inserted into track to become
effectively invisibles. When a segment becomes reduced, a TrackEvent
is generated to remove it. Conversely when it is raised a RoutingEvent
is created/rescheduled to insert it. All this is mostly managed inside
the Session::revalidate() method.
* New: In Kite, in KiteEngine::createGlobalGraph(), in case of a chip,
mark all global routing vertexes (Knik) that are under a pad, as blockeds.
* Bug: In Cumulus, in PadsCorona.Side.getAxis(), inversion between X and
Y coordinate of the chip size. Did not show until a non-square chip
was routed (i.e. our MIPS R3000).
* Change: In Stratus1, in st_placement.py add the ClockBuffer class for
backward compatibility with the MIPS32 bench. Have to review this
functionnality coming from the deprecated placeAndroute.py.
In st_instance.py, no longer creates the Plug ring of a Net.
In my opinion it just clutter the display until the P&R is called.
Can re-enable later as an option (in Unicorn).
* Change: In Unicorn, in cgt.py, more reliable way of loading then running
user supplied scripts. Borrowed from alliance-checker-toolkit doChip.py .
* New: In CRL Core, created a LibraryManager widget. It provides a
composite information based on what is present, for each
Alliance library:
1. - A Cell in memory, without Catalog::State.
2. - A Catalog::State, with or whithout the Cell in memory.
3. - The files of the Cell in the librariy's directory.
4. - A file with a format referenced for one of the importers.
File type recognition is based *only* on the file extension,
so it may easily confused. Be careful about what you put in
the library's directory.
One of the big limitation is that it will not display Hurricane
libraries that do not have the AllianceLibrary extension.
This widget is put in a separate library <libmanager>, included
in the default CRLCORE_LIBRARIES.
* Change: In CRL Core, in State (through the loader), now sets the
InMemory flag (event if nobody uses it yet...). Display it in
the state _getString().
In AllianceFramework, new getAllianceLibraries() method.
In CatalogExtension, make the static method "get()" publicly
accessible, for sometimes we want the whole State.
* Bug: In vlsisapd, in Path, the pathcache was not rebuild when it
should, leading to incorrect results.
* New: In vlsisapd, in Path, added a listdir() method to access the
contents of a directory and a stat() method to poll the status
of a file/directory.
Rename the ".string()" method in ".toString()" to avoid
tricky name resolution with std::string, refactor in all the
other tools.
* Change: In Hurricane, in Controller, no longer oversize the fonts
of the table's headers.
* New: In Unicorn, in UnicornGui, integrate LibraryManager.
* Error messages are more explicit in Ap and Blif parsers
* Warns when not using tie cells
* New layer synonym in ApParser for easier format conversion
* Blif import is now on top
* New: In Hurricane, In NetAlias & Net, add an AliasList collection to
iterate over all the aliases names (this *not* include the main
net name).
* New: In Hurricane, In Cell, Instance & Net add support for cloning and
uniquification (update documentation).
All Cells that are uniquified from a given model are kept in an
Uniquify relation. This relation allows to get all the clones and
generate unique clone names by adding a "_uXX" suffix.
* Bug: In Hurricane, the Cell::_isFlattenLeaf attribute was not initialized
in the constructor.
* Change: In CRL Core, in AllianceFramework::getCell(), no longer destroy
a partially loaded Cell in case of parser failure, let the incomplete
Cell be.
* New: In CRL Core, in ApParser, if all the instances are placed, sets the
Cell::Placed flag.
* Change: In CRL Core, in BlifParser, complete rewrite of the parser.
Not so good an idea afterwards...
* New: In Etesian, uniquify the design before placing.
* Change: In Kite, display the list of unrouted wired after all other
statistics.
* New: In Hurricane, In Net & Cell, support for Net aliases names.
Use a structure based on a simple ring of NetAliasHook. The Net
holds a global map, sorted by names of all the aliases of all Nets.
Elements NetAliasesHook of the map are slaves of ring whose master
is an attribute of the Net (it is *not* in the map, as the primary
name of the Net).
In case of merge, the aliases of both Nets are merged and the
name of the merged one become an alias.
The Cell::getNet() looks in both the Net map and the aliases to
find a Net by name.
* Bug: In CRL Core, in coriolisInit.py, reoder the loading of the
configuration files so the real technology is read as early as
possible to set up the <gridsPerLambda> factor before any lambda
is actually computed...
* Bug: In CRL Core, in AcmSigda, do not try to fed the file when it
has failed to be opened. Throw a clean exception instead.
* New: In CRL Core, in Toolbox, add a NamingScheme object to convert
a design into VHDL compliant names (mainly from Blif/Verilog).
This is extensible in any case.
* New: In CRL Core, in BlifParser, slightly more informative warning
messages. Align the loading progress information on the other
parsers.
Add a capability to select which component of the design will
be returned, if there are more than one. Use the "." as separator.
For exemple you can request "Processor.Alu", which will load
the "Alu" component from the design in "Processor.blif".
To be able to save a Blif loaded design, systematically convert
all the name for VHDL compliance, as it is the format used by
the Coriolis native files (vst).
Export the Blif parser to the Python interface.
* New: In Kite, In NegociateWindow, add a counter of the number of
remaining events. Gives an idea of the ETA...
* New: In Unicorn, in cgt.by, add an option to load a Blif design from
the command line.
* New: In Cumulus, new RSave plugin to save both netlist & layout.
Partly redundant with the previous one. Have to better organize
that later.
* Change: In CRL Core, simplify the loading sequence. The technology,
both symbolic and real is now loaded directly from coriolisInit.py
and not through the Alliance loader. This was a leftover from the
time configuration was in XML. Remove others traces of XML loading.
Remove SYMB_TECHNO_NAME, REAL_TECHNO_NAME & DISPLAY from the Alliance
environement, as they was no longer used.
Note that technology *still* need to be loader *after* Alliance
framework has been initialized.
Gauge information is moved from <alliance.conf> to <kite.conf>.
* Bug: In Coloquinte, in optimization_subproblems.cxx static variables
must not be inlined. Generate a problem when linking in debug mode
(seems the symbol gets optimised out).
* Bug: In Katabatic, in Grid::getGCell(), when the coordinate is *outside*
the area, do not try to find a GCell, directly return NULL.
* New: In Unicorn, create a generic command launcher named "coriolis" which
automatically take cares of all environement setup, then run a command
by default, it's <cgt>, but it can be anything. For example: <zsh>.
* New: In Hurricane, In CellWidget, add methods to emit CellPreModificated
and CellPostModificated Qt signals (from non-Qt aware objects).
* New: In Unicorn, In ImportCell, parsers are now dynamically hooked
in the importer, allowing third party application (i.e. Chams) to
add their own. See the ImportCell::addImporter() method.
* Bug: In Unicorn, in FindUNICORN.cmake, seems to be unable to detect
the UnicornGui.h. Not a blocking problem because the include dir
is shared with other tools correctly detected. But still...
* Change: In Bootstrap & ccb, the coloquinte project is renamed into
"importeds", it will be the home of all the externally
devellopped softwares that are needed to build Coriolis.
Add explicit support for Fedora ("Linux.fc") and uses
site-packages, as everybody else.
* New: In CRL Core, in etc/, adds the configuration files for Etesian.
* New: In Etesian, activate the Configuration object. Now uses it's
own configuration variables instead of borrowing those of
Nimbus & Mauka.
* Change: In Documentation, updated User's Guide to present Etesian
as the placer, instead of Mauka.
* Change: In Cumulus, slight change in ClokTreePlugin and ChipPlugin
to match the new Etesian/Python interface.
* New: In Bootstrap, in ccb.py, check if cmake is installed and issue
a warning, if not.
* New: In Hurricane, added Cell::getDeepNet() to search for a deepnet
given a path and a leaf net. This method is slow and must not be
used too often. Introduced for Kite::BuildPowerRails().
* Change: In CRL Core, in cmos/alliance.conf, modify the clock name
pattern to match the sub-clock signals in the datapath operators.
* Bug: In Etesian, do not blindly reset the top cell abutment-box.
Do it only if it's empty, otherwise keep it.
* Bug: In Kite, in buildPowerRails(), in getRootNet() the management
of clock nets was incomplete. The case of unrouted clock nets
that where not connected to the top core clock net, like the
one in the datapath registers was faulty. They were partly
recognized as unrouteds and partly as blockage generating a
routing deadlock: routage impossible due to blockage generated
from itself...
* New: In Stratus1, add a buildModel() utility function to automate
the model generation and allow a call by the model name (string).
* Change: In Unicorn, in cgt.py, display the Alliance environement.
* New: In Bootstrap, added support for RHEL7 in ccb.py & coriolisEnv.py.
In coriolisEnv.py, under RHEL6, directly launch a shell under
devtoolset-2 (do not put it in .bashrc).
* Change: All tools, compliance with Clang 3.2.
- Call using namespace std *after* at least one include of std has
been used.
- In Utilities.h define both const and non-cont overload for operator<<
of mstream (this was the true cause of the Banner display problem).
- No longer use defaults arguments in templates, instead create two
separated overloads.
- Put template static attributes allocation outside of namespaces
(this one I'm not sure how to justify).
- Protect by NDEBUG variables that are only needed in assert().
- In PyInterval getUnion() & getIntersection() we where silently
overwriting the "self" object (interval).
- In Mauka, *do no* overload _postCreate() and add an argument, breaks
the virtual function mechanism. Rename it into _maukaPostCreate().
Idem for SubRow().
- In Katabatic::GCell(), invalidate() overload a Go funtion but is
used for different purpose at this level. Rename it invalidateCt()
(invalidate *ConTents*).
- Miscellaneous small cleanup.
* New: In Unicorn, in ExportCellDialog and UnicornGui add an entry to
call the ASCII/GDSII export driver.
* New: In CRL Core, in AgdsDriver, checks for off-grid coordinates (that
is non-integer one) and round them with a warning. This is most
likely that the layout is flawed but it will at leat generate a
readable ASCII/GDSII file.
* Change: In bootstrap, in ccb, builder and coriolisEnv.py, correct detection
of the windows architecture (32 or 64 bits). Under Cygwin, add the
directory of the dll into the PATH also. Uses "site-package" as the
location of Python modules (*not* "dist-package").
Use gnu++0x under Cygwin instead of c++11.
* Change: In Etesian, if Coloquinte is not found, do not stop the compilation,
just disable the tool altogether.
* Change: In Hurricane, In Backtrace, disable backtrace under Cygwin as it
uses features specific of the glibc.
* Change: In Knik, use HUGE_VAL instead of HUGE (not present under Cygwin),
add the <cmath> header.
* Change: In Unicorn, Coloquinte no longer stops the compilation.
* Change: In bootstrap, in ccb & builder, build by default with Qt4 and
provide a --qt5 command line switch to enable Qt5.
FindBootstrap.cmake now provides a qtX_wrap_cpp() macros to be
independant of the version of Qt being used.
Add all thoses options to the graphical interface to the builder.
* Change: In all the tools using Qt, switch to the qtX_*() macros from
FindBootstrap.cmake.
* Change: In Hurricane, in CellViewer, revert to the Qt4 way of connecting
signal/slots for backward compatibility.
Finally get rid of the demonic code from Wu Yifei...
* New: In Isobar, added encapsulation of Interval (don't know how have
forgotten it for so long).
* Change: In Isobar, In PyLayer, new PyLink_LayerDerived() function to
create/link the C++ object to the correct derived class and not the
base one (PyLayer) which then prevent to use the specialized methods.
Must replace PyLink_Layer() througout all the code.
* Change: In Isobar, in PyPoint the "setX()" & "setY()" methods where
still capitalized.
* Change: In Isobar, in PyQuery, complete the exportation of the C++
interface. remove the code belonging to a more "boost" way of
building the Python interface (will do that in a far future).
* New: In CRL Core, In PyAllianceFramework, export isPad() method.
* Change: In Unicorn, in unicornInit.py, protect the loading of each
single plugin by a "try" / "except" clause to the failing of one
plugins do not stop the loading of the next one.
Pass the same dictionnary argument to unicornHook() as for
ScripMain(), this is more uniform this way.
* New: In Cumulus, complete replacement of the chip placement scripts
from Wu Yifei (at last!). The clock-tree integration is still to
be done.
________________________________________________________________________
* New: In all to CMakeLists.txt, disable the warning about deprecated
WIN32 under cygwin.
* New: In boostrap, in ccb.py, coriolisEnv.py and builder/Configuration.py
add recognition in uname for the values returned under Windows/Cygwin.
* New: In Documenation, in UsersGuide.rst add some informations about
Cygwin and a section for the devel branch.
* Bug: In Kite, in TrackCost, the boolean attribute "_forGlobal" was not
initialized in the constructor causing the non-deterministic behavior.
Arrrrgggghhhhhh.
* Bug: In Kite, in PyKiteEngine, forgot to perform the
"balanceGlobalDensity()" in the layer assign Python wrapper, another
cause for non-determinism.
* Change: In Kite, In KiteEngine, print the configuration at the same
point as in the python script (to get identical output).
* New: In Isobar, export the DebugSession mechanism.
* New: In Kite, In KiteEngine, add the ability to run a Python script
(hook) after the initialization of the KiteEngine.
* New: In Isobar::Script, scripts arguments are now passed through a
"keywords" argument (Python: **kw), that is a dictionnary.
To add *any* Python object to that dictionnary, uses the new
method Script::addKwArgument(const char* key, PyObject*).
The "cell" and "editor" variables are now passed that way.
This means that, for the editor, the old way of inserting
a symbol in the module global dictionary is no longer used
and the Python scripts must be modificateds.
* New: In Hurricane::PyCellViewer, create the Python link function
for translation from Hurricane to Python.
* New: In Unicorn, modifications for the new argument passing for
the Python scripts.
* New: In Katabatic, add the ability to decorate some (i.e. few) nets
with a state that indicate to Katabatic & Kite what to do with it.
The possible states are:
1. Fixed : all the wire are in fixed positions. The router cannot
move them and account them as obstacles.
2. ManualGlobalRoute : a user-defined topology is supplied. The
wires still have to be detailed route in "Detailed Pre-Route"
but will be skipped for the global routing and fixed for the
general Detailed route.
3. AutomaticGlobalRoute : ordinary nets, to be global routed then
detail routed.
4. Excluded : do not try to global or detail route thoses nets.
5. MixedPreRoute : mask combining Fixed and ManualGlobalRoute.
Not all nets have this property, only those that needs a special
processing.
To ease the access to the state, it is nested inside a
PrivateProperty in the net (NetRoutingProperty), with an extension
access class (NetRoutingExtension).
* New: In Kite, take account of NetRoutingState. Pointers to the
net's states are strored inside an internal map for faster access.
The property is *not* deleted when Kite is destroyed. The property
will remains until the Net itself is destroyed.
As a consequence, the lists that where passed to high level
function are removed as the information can now be accessed directly
through the net NetRoutingProperty.
* New: In Unicorn, in CgtMain, comply with the update interface.
* New: In documentation, update the User's Guide to explain the Pre-routed
step of Kite.
* New: In Hurricane, in CellViewer, create a simpler API to graft menu
and actions into the menubar. Mainly addToMenu() which take care of
the QAction creation but also locate the relevant QMenu, base on
the Qt object name. Regroup all the widget & action creation inside
the body of the constructor, this way almost all actions can be
removed from the attributes of the CellViewer.
addToMenu() is supplied in three flavors:
1. For C++ callbacks in GraphicToolEngines (with a binded
member function method).
2. For running Python scripts to be used by the plugin system.
3. To insert separator in menus (to give a more homogeneous
look).
Remove the last remnants of Stratus scripts (unificated with basic
Python scripts).
* New: In Hurricane, in PyCellViewer, export the interface to graft
Python scripts into the CellViewer menu tree.
* Change: In Etesian, in GraphicEtesianEngine, use the new API to
graft menus & callbacks into the CellViewer.
* Change: In Mauka, in GraphicMaukaEngine, use the new API to
graft menus & callbacks into the CellViewer.
* Change: In Kite, in GraphicKiteEngine, use the new API to
graft menus & callbacks into the CellViewer.
* New: In Cumulus, install Python scripts as plugins for Unicorn under
<PYTHON_SITE_PACKAGES>/cumulus/plugins/.
* New: In Unicorn, in UnicornGui, make uses of the new API for creating
menus in the CellViewer. Creates the stem menu for the P&R tools.
Add a Python initialization mechanism to read the plugins
installeds into <PYTHON_SITE_PACKAGES>/cumulus/plugins/.
* Change: In Kite, Katabatic & Knik, express the number of tracks truly
available to the global router by the number of tracks reserved to
the local routage inside a GCell. Replace the ratio parameter
"hEdgeCapacity" by an integer parameter "hTracksReservedLocal"
(duplicate for verticals).
It is more explicit to give directly the number of tracks that
are to be used locally, and potentially saves us from rouding
problems when calculating the number of availables tracks.
Note: we cannot do that for the layer saturateRatio as it
uses the density ratio that take account local wires, leading
to fractional results.
* Change: In Katabatic, in <GCellGrid>, rename checkEdgeSaturation()
into checkEdgeOverflow(), more explicit.
* Change: In Knik, in <Graph>, display the computed capacities of the
lower left node edges (should be the same througout all the grid).
* Change: In Unicorn, in <cgt.py>, uses the new parameters names for
edge density.
