* Bug: In Hurricane, in CellWidget, do *not* rescale iteratively the _initialSide
attribute under high DPI (do it once).
* Bug: In Hurricane, in CellPrinter, suppress the divide by 4 scaling of the
printer widget. Don't remember why I did so, and it generate too small
pictures.
* Bug: In Hurricane, in Cell::_preDestroy(), the classic mistake again:
do not iterate over a collection while deleting it's elements.
Now should be safe.
* Change: In CRL Core, set the default display style to "Alliance.Classic [black]"
(my favorite).
* Change: In bootstrap, in socInstaler.sh, use the current version of
rapidjson.
* Change: In Hurricane, in FileWriteGzStream, complie to the latest
rapidjson headers organization.
* New: In Hurricane, in Cell, emit a new signal CellDestroyed toward the
observers (i.e. the CellViewer(s)), from _preDestroy().
* Change: In Hurricane, in CellViewer, in CellObserver::notify(), manage
the CellDestroyed case. Do not forget to remove the deleted Cell
from the viewer's history.
* 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...
* New: In Hurricane, in NetlistWidget & NetlistModel, adds a column for
the RoutingPads count. Special display to mark global nets.
* Change: In Hurricane, in all MVC's models, some improvements on the
way the columns are sized and the titles displayeds.
* New: In Hurricane, added hierarchy browser in the controller.
The hierarchy is presented as a tree. New MVC, HierarchyInformations,
HierarchyModel and HierarchyBrowser.
When using a data model which is not directly connect inside the
model, we must use the internalPointer field of the QModelIndex.
But this field is also used by the QSortFilterproxymodel, this
prevent using it with a Tree model.
The filter is directly implemented and is specific to each
Instance entry.
* Change: In CellWidget & CellWidget::State, now store the Cell and
a Path, this way we can keep track of the hierarchy when browsing.
The Path is in the State and so propagated back to the Controller.
* Change: In HierarchyCommand, use the Path with setCell().
* New: In Hurricane, in Cell & Instance, add the ability to merge the
QuadTree when *second level* instances of a Cell are placed in
the same space as the top Cell. This is the case of a deeply
hierarchical design made of only standard cells that are to
be placed in a "flat" manner.
The design is uniquified then the intermediate instances models,
which should be unique at that point have their QuadTree merged
through a call to Instance::slaveAbutmentBox(). That method will
make the model of the instance use the QuadTree of the Cell to
which the instance belong. The instance model no longer posseses
a dedicated QuadTree. As a corollary the abutment box of both
Cell are kept identical and the Instance has it's transformation
set to (0,0,ID).
Remark: when we talk about "QuadTree", we mean in fact the
QuadTree for the instances *and* the SliceMap (Layer+QuadTree).
Consequence in Query: when going through the resulting
"flattened" QuadTree we will find objects with an incomplete
Path du to the fact that we didn't have to explore their
Instance/Cell level to reach them. The shunted part of the
Path is stored in the Go master Cell in the _shuntedPath
attribute. This also affect the displayed depth of hierarchy,
but not too badly.
* New: In Hurricane, in Cell, new methods:
- Cell::updatePlacedFlag() : set the placement flags.
- Cell::isUnique() : one or less instance.
- Cell::isUniquified() : is the result of an uniquification.
- Cell::isUniquifyMaster() : is the reference cell of the
uniquification.
* Change: In Hurricane, in Cell::Uniquify(), uniquify a Cell only
if it is unplaced. We do not need to duplicate placed Cells
(see datapathes).
* New: In Hurricane, in Cell, no longer create rings of RoutingPads when
flattening the nets. Put that functionnality into a separate method
::createRoutingPadRings().
This allow to perform the Net flattening in Etesian *without*
the rings, which slow it down. Then the rings are created by
Knik/Kite. This also solves the double ring creation when doing
P&R of a complete chip (rings where created twice: in the core
block for Etesian and at chip level for Kite).
* Change: In Etesian, slight beautification of the printed informations.
(psychorigid me)
* Bug: In Hurricane, In NetAlias::removeAlias(), perform the isMaster()
check on the *current* hook, not the *this* one... Was preventing the
removal of most aliases.
* New: In CRL Core, in DefExport, perform a virtual flatten before exporting
a design. Replace the hard-wired "sxlib" gauge by the current default
one. More secure management of flattened instance and net names (removal
of all potentially special characters). In net names, correct management
of vectorized names (do not systematically add "_net" at the end).
In DefImport, manage the BUSBITS property and revectorize accordingly
the net names. When loading nets, systematically remove the alias of
the temporary net "__prebuild__" (a bug in NetAlias was preventing it).
In LefExport, the right value of MANUFACTURINGGRID in pseudo symbolic
mode is 0.5 (expressed in lamba). That way all length are even multiples
of it. Note that there is still the order bug of the 5.7 drivers that
puts that entry *before* UNITS in the LEF file (bad bad Cadence).
* Bug: In Hurricane, in Instance::getClone(), the Instance::create()
was called with a wrong number of parameters, causing the the
wrong overload to be called. The position was thus not copied
generating an unplaced copy. This was causing error in the
AM2901/datapath bench, because fixed blocks where becoming
unfixed.
* Bug: In <bootstrap>, in coriolisEnv (again) an error in the
detection of the LD_LIBRARY_PATH.
* New: In Hurricane, dedicated class BaseFlags to wrap a set of flags.
Similar to the Mask class, only with a slightly different semantic.
Encapsulation of <unsigned int>.
Also provide support for the Inspector, to have a human-readable
display of the flags.
* Change: In Hurricane, in Cell, regroup all the flags under a Flags
sub-class of Cell. No more mixing between booleans and bit flags.
(first use of BaseClass).
* In Hurricane, CRL Core & Knik, many small corrections to suppress
annoying warning messages at compile time.
Most noticeably, Bison errors in VstParserGrammar generated by
rules and token with mismatched return value type. This was not
problematic because the badly defined return value where not used.
But still...
* New: In Hurricane, in Collection add simple STL iterator support.
So now the C++11 "for" instruction can be used instead of the
in-house "forEach".
Example:
forEach ( Component*, icomponent, net->getComponents() ) {
cout << (*icomponent) << endl;
}
Become:
for ( Component icomponent : net->getComponents() ) {
cout << icomponent << endl;
}
* New: In Hurricane, in Graphics, add a new static method ::isHighDpi()
which returns true if the DPI is greater than 192. A "normal" screen
is typically 96dpi, we sets the trigger at twice that value.
Then in all the widgets with size settings, we uses that method to
select the more appropriate size.
* Bug: In Hurricane, in PyHurricane.h the macro HCATCH was not catching
standard STL exceptions. This was the source of the cryptic message:
"Fatal Python error: Py_EndInterpreter: thread still has a frame"
The Python interpreter was interrupted uncleanly bypassing it's own
exceptions mechanism.
In PyViewer, the Viewer *do not* inherit from a base class (in the
Python export).
* New: In Hurricane, in DbU, compute maximum values (in double) for
grid, lambda & physical (in meter) so now the DbU::toGrid(),
DbU::toLambda() & DbU::toPhysical() methods can check for out of
bound values, and throw an exception.
* Change: In Hurricane, ExceptionWidget::catchAllWrapper() now returns
a boolean, set to <true> if an exception has been catched. Allow
callers to interrupt themselves if a problem has occured.
* Bug: In Kite & Etesian, in the Python wrapper, send a Python exception
if catchAllwrapper() did return true, instead of continuing...
* Change: In Kite & Etesian, adds a setViewer() method (exported in Python)
to use the graphical ExceptionWidget when in graphic mode.
* Bug: In Cumulus, in PadsCorona.py the check for the core vs. chip size
was not returning False when invalid.
* New: In CRL Core, in Vst driver, add a support IEEE VHDL. Inactive for
now as I don't see clearly the policy for selecting it or not.
Remove the code of the old Vst driver.
In Blif parser, check for non-existent models (incomplete or
corrupted Blif file). Found by G. Gouvine.
* New: Added extras file for IDE-like support under Emacs.
* 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.
* Bug: In Hurricane, in NetAlias, bad Record construction of the _next
field.
* New: In CRL Core, in VstDriver complete replacement of the old Vst
driver. Needed cleaner architecture to manage correctly files
importeds through the Blif parser, which are Verilog like.
It is build as an extension trough property and is not kept
in sync with the Cell. So it's use should be transient only.
* Change: In CRL Core, in NamingScheme forgot to change '.' (dot)
forbidden character into '_'.
* Change: In Cumulus, in the RSave plugins, remove the VHDL extensions
after saving.
* 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 Cell, add Placed and Routed flags to know the
state of the Cell.
* Change: In CRL Core, In ApDriver, do not save the RoutingPads as
external connectors if the design is *not* routed (create
conflics on reload with the newly generated RoutingPads).
* Change: In Etesian, set the Placed flag on the Cell.
* Change: In Kite, set the Routed flag on the Cell.
* Change: In Cumulus, in RSavePluginAll, save the layout only if it
has a bounding box.
* 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 CRL Core, remove obsoleted XML files, no longer needed by
Chams. Add stub for technologies CMOS065 (ST) and C35B4, aka
AMS 035.
* Bug: In Knik, update the path where to find the FLUTE lookup tables.
(from 2.4 to 3.1).
* Bug: In Hurricane, In CellViewer, pass by a temporary pixmap when
shitfing right (and bottom). We were already using the AutoCopy
buffer for the opposites moves... Seems that the drawPixmap()
may have changed of implementation.
Explanation of the diagonal lines, see QTBUG-31579 that affect
Qt 4.8.5. Temporary work around, force the pen to have a width
of 2 pixels (for _normalPen & _linePen).
* Change: In Hurricane, in CellViewer remove the redraw by whole
strip mechanism (offsetVA).
* New: In Hurricane, In CellViewer::DrawingPLanes add a tracking of
the brush offset to avoid small irregularities at the border of
two separately drawed areas.
* Bug: In Hurricane, in Graphics, display a warning about the
diagonal lines when using Qt 4.8.5.
* Change: In Hurricane, in Script.cpp, remove the call to Py_Finalize()
as it do not completly clear the Python interpreter, causing in
Chams disgraceful warning about a double initialization.
Not calling this clearing function do not seems to cause problems
do far (maybe memory leak...).
* 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...
* New: In VLSISAPD, in Configuration, add a new priority level UserFile
to distinguish between the system configuration files and the user's
configuration files (which take precedence).
* New: In Hurricane, in Script (Python), improve the API to be able
to support Chams (and remove the duplicate capability from it).
Add separate functions to perform the initialize/run(s)/finalize
cycle step by step.
* Change: In CRL Core, rename real technology <hcmos9> to <hcmos9gp>,
it's offcial name from CMP/ST. This is the 130nm.
Move the reading of the symbolic & real technologies names from
coriolisInit.py to helpers.__init__.py, to be shared with
chamsInit.py.
To avoid a clash of names inside of helpers, the two variables
of techno.py are renamed "symbolicTechnology" and "realTechnology".
Move python init system from crlcore/src/crlcore to crlcore/python.
* New: In CRL Core, In Utilities, add site-packages/pharos to the
PYTHONPATH.
* Change: In Kite, move python init system from kite/src/init to
kite/python.
* Change: In Cumulus, in Configuration.py, in the horizontal & vertical
wire creation adds new flags ExpandWidth to draw wires one lambda
bigger than the minimal width (see ClockTree.py patch).
* Change: In Cumulus, In ClockTree.py, use non default width to draw
wires of the H branch of the clock tree. This is to prevent them
to be recognized as "manual global routing", which they are not
and not event topologically compatible.
* Bug: In Kite, in BuildPowerRails, change the way clocks are detected
when working on a single block (not a whole chip). Now look only
in clock which are external and do not filter out already routed
ones.
* Change: In KiteEngine, in createGlobalGraph(), systematically call
flattenNets() so nets that are added after the first flattening
in the placer are also flattened. The flattenNets() Cell method
takes care of not flattening twice a net.
* 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 Hurricane, in DebugSession, add a new method to activate the
trace inconditionally with a certain level.
* New: In Hurricane, in HyperNet, allow copy construction as there is
no reason to disallow it and we need it now.
* New: In Hurricane, in Cell::flattenNets(), add a new option to prevent
the flattening of the clock net(s). For more safety perform the
DeepNet creation *outside* the Collection loop.
* Bug: In Hurricane, in Cell_HyperNetRootNetOccurrences, skip the
DeepNets because they are the result of another flattening operation.
* New: In Isobar, in PyBasicLayer, export C++ method getBlockageLayer().
* New: In Isobar, in PyRoutingGauge, export C++ method getLayerPitch(),
needed by Cumulus plugins.
* New: In Etesian, EtesianEngine::findYSpin() to look for the Y orientation
if some cells are already placed. Typically the buffers of a clock
tree.
Pass the correct orienation to row_compatible_orientation().
Do not try to add feeds in the ISPD05 benchmarks. For now the
benchmarks are detected through their names (unreliable).
* Change: In Knik, in KnikEngine::initGlobalRouting(), allow the clock
to be routed as an ordinary signal when the clock tree is not
used.
* New: In Kite, in BuildPowerRails, management & detection for the
pre-routed clock.
In KiteEngine constructor, early initialization of the blockage
net to avoid later troubles in BuildPowerRails.
* New: In Cumulus, in ChipPlugin, add support for Etesian plus new
configuration parameter 'clockTree.placerEngine' to select between
Mauka and Etesian.
* New: In Cumulus, in BlockCorona, add blockages in the vertical sides
in the vertical layer to prevent the router to use the vertical
tracks in under the prower lines (for example, blockage in M3
with power line M5).
In Cumulus, in ChipConf add attribute to access the blockage net.
* New: In Cumulus, when the clock tree is disabled, do not generate
the last rail around the block (the clock rail).
* Bug: In Cumulus, in ChipConf use the clock pad to guess the clock
signals and *not* the power pad.
Add more meaningful error messages if a pad global signal is
not found (implicit connexion by name).
* Bug: In Cumulus, in ClockTree, compute correctly the cells Y spin,
that is *from the bottom of the cell AB* (not from 'zero').
* Bug: In Bootstrap, in coriolisEnv.py, check if devtoolset-2 is already
active before launching it as a sub-shell.
* Bug: In Isobar, In PyHurricane.h, DBoDestroyAttribute() set the proxy
pointer toward the C++ object to NULL. So when the Python object is
deleted no double-deletion occurs on the C++ object.
Add some more trace information in Python link/dealloc.
* Change: In CRL Core, in cyclop, make CMakeLists.txt automatically
choose the right rule for linking the binary wether we use Qt 4 or
Qt 5. Very irksome problem.
* New: In EtesianEngine::addFeed(), do not take into account instances
that are not placed entirely inside the top cell abutment box (was
causing a core dump).
* Bug: In Katabatic, in GCellQueue, correct a mismatch between a GCell
set and the iterators used upon it.
* Bug: In Mauka, in Row & Surface correct a mismatch between a container
and it's iterator.
* New: In Etesian, updated to work with the latest Coloquinte, patch
contributed by G. Gouvine.
Added EtesianEngine::setDefaultAb() to compute an abutment box if
the Cell is completly unplaced.
* New: In cumulus, in ClockTree, now the placer can be configured to be
either Mauka (slow simulated annealing) or Etesian (fast analytic).
New setting 'clockTree.placerEngine' in plugin settings.
* New: In Bootstrap, in Builder & coriolisEnv.py support for RHEL7/SL7.
The sub-directory name is 'el7_64'.
In qt_setup() add QtSvg to list of Qt5 & Qt4 used libraries.
* New: In Hurricane, In Cell add a placeholder for flags. First use to
store whether the Nets have been transhierarchically flatteneds.
* New: In Hurricane, In NetRoutingState add an Unconnected flag for
more accurate diagnosis.
* New: Hurricane, in CellViewer add an entry menu for stress tests.
The script must be named "stressScript.py" in the cwd.
* Change: In CRL Core, in display.conf add a scaling parameter for the
display threhold of the layer. This way we can adapt to different
standard cells height.
* Change: In CRL Core, in ISPD05 bookshelf loader, use the pitch of the
cell gauge instead of a hard-wired 5.0.
* Change: In Cumulus, in ClockTreePlugin, add support for Etesian placer
and a new configuration parameter to choose between Mauka/Etesian.
* New: In Etesian, support for the latest Coloquinte.
Add feed insertion stage.
* Bug: In Kite, In BuildPowerRails, check that _ck is not NULL before
tring to access it's name...
* Change: In Kite, check if the Cell has it's Nets flattened before
doing it (or not).
* 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.
* Change: In Hurricane, in RoutingPad::setOnBestComponent(), in case of
area equality, do not choose on id but the geometrically lowest one.
Between two runs of the global router, it is not possible to
maintain identical ids. This may leading to a change to the selected
component, and a change of the GCell it in, which cause bad
topologies when read by Katabatic.
* Change: In Hurricane, the NetRoutingProperty is moved into Hurricane
from Katabatic. Needed for Knik to be able to access thoses
informations.
* Change: In Hurricane, in RoutingPad::setOnBestComponent(), now in
case of identical area, select the component of lowest id.
This should not be needed if the component ordering was fully
deterministic as it should be (will investigate later).
This is to ensure that the choosen component is always the
same, especially between save/load of a global routing.
* Bug: In Katabatic, in AutoContactHTee::updateTopology(), invalidate
the segments only if the topology is valid (no NULL in the
cached segments).
* Bug: In Katabatic, in GCellTopology::construct(), throw an error
if the topology is bad instead of trying to continue (and core
dump later... ).
* Bug: In Kite, in BuildPowerRails, distinguish the name of the master
net in the pad (for vddi, vssi, vdde, vsse, ck, cki & cko) and the
name of the net in the *chip* netlist. Must use the later to make
comparison as they may differs.
* Change: In Knik, in save/load solution, exclude nets that are not
globally routed by Knik. That is which NetRoutingProperty is not
*Automatic*.
* Bug: In Cumulus, in chip.BlockPower take account of the layer
width extention to sligthy shrink the connector thus avoiding a
notch with standart cell in some cases.
* Change: In Cumulus, in chip.ClockTree disable the use of fixed Steiner
trees for the leaf clocks, as it seems overconstrained for the
router. First move was to lower them in M2/M3 (instead of M3/M4)
but that was not sufficent.
* New: In Cumulus, RSavePlugin for recursively saving a physical
hierarchy.
* New: In documentation, first embryo for RDS file. Should have been
in Alliance git, but I prefer to keep newest doc in Coriolis.
* New: In CRL Core, in helpers & alliance.conf, set and read a "PAD"
variable to define the pad model name extension ("px" for "sxlib
and "pxr" for vsxlib, this is provisional).
* New: In CRL Core, in plugin.conf, add parameters to define the name
of used for power & clock supply. We may remove the extention in
the future (to be more coherent with the previous modification).
* New: In Cumulus, in chip.Configuration.GaugeConf._rpAccess(), no
longer place the accessing contact *at the center* of the
RoutingPad. It works under sxlib because buffers & registers all
have same size terminals. But this is not true under vsxlib,
leading to misaligned contacts & wires. Now systematically place
on the slice midlle track (maybe with one pitch above or below).
This is still very weak as we do not check if the terminal
reach were the contact is being put. Has to be strenthened in
the future.
* New: In Cumulus, in chip.Configuration.ChipConf, read the new
clock & power pad parameters.
* Change: In Isobar (and all other Python wrappers), uses PyLong instead
of PyInt for DbU conversions. In PyHurricane argument converter,
automatically check for both PyLong and then PyInt.
* Change: In Cumulus, in chip.PadsCorona, more accurate error message
in case of discrepency in global net connections (i.e. no net
of the same name in instance model and instance model owner.
* Change: In Kite, in BuildPowerRails, when looking up at the pads
model name to find "pck_" or "pvddeck_", do not compare the
extension part. But we still use hard-coded stem pad names,
maybe we shouldn't.
* Bug: In Katabatic, in GCellConfiguration::_do_xG_xM1_xM3(), there
was a loop in the search of the best N/E initial RoutingPad.
* Bug: In Kite, in KiteEngine::protectRoutingPads(), *do not* protect
RoutingPads of fixed nets, they are already through the
BuildPowerRails stage (and it's causing scary overlap warning
messages).
* Bug: In Cumulus, in ClockTree.HTreeNode.addLeaf(), do not create
deep-plug when the core is flat (not sub-modules). All the new
nets are at core level.
* Bug: In Cumulus, in ChipPlugin.PlaceCore.doFloorplan(), ensure
that the core is aligned on the GCell grid (i.e. the slice
grid of the overall chip).
* Bug: In Kite, in GCellTopology::_do_xG_xM1_xM3(), infinite loop
while looking for the bigger N-E RoutingPad. Forgot to decrement
the index...
* Bug: In ClockTree plugin, only the logical view of the clock buffer
was loaded, so no external components where found on the I/O nets.
The external components are loaded only when the *physical* view
is loaded. Didn't show on sxlib because the buffer was fulled
loaded *before* running the ClockTree.
* Bug: In PyHurricane, in the various LocatorNextMethod() macros,
sometimes an empty collection can be returned by Hurricane
(GenericCollection()), which has a NULL locator. So check
if the locator is *not* NULL before trying to access it...
* Change: In Chip, more accurate error messages related to the clock
detecttion.
* Change: In Hurricane, in Plug::setNet(), more informative error messages.
* Change: In Hurricane, In Segment, more informative error messages.
* Change: In Hurricane, In DeepNet, accessor for the Net occurrence.
* Bug: In Katabatic, in AutoSegment::create(), error message uses correct
variables (vertical was using horizontal)...
* Change: In Kite, in BuildPowerRails, already existing wiring in instances
is copied up as blockage. Uses blockage layer instead of true layer
(it was a bug).
* Change: In Kite, in BuildPreRouted, consider as manual global routing
nets with only default wiring (default size wire & contacts).
Non-default routing is flagged as fixed (with the NetRoutingState
property).
