* 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).
* 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.
* 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.
* Change: In Isobar, the Python interface was not exactly mirroring the
C++ one, now it is the case. The Python code should look likes almost
exactly like the C++ one, the only differences remaining being due
to the languages respective syntaxes. Note that in the case of
constructor functions, it leads to a slightly longer notation in
Python that it could have been (mimic the ".create()" static
member). Main modifications:
1. Mirror the static constructor syntax with create():
Cell( ... ) ==> Cell.create( ... )
2. Correct hierarchy for constants in Instance, Net, Pin
& Transformation. For example:
Hurricane.PlacementStatusFIXED
==> Hurricane.Instance.PlacementStatus.FIXED
Hurricane.OrientationID
==> Hurricane.Transformation.Orientation.ID
Hurricane.TypeLOGICAL ==> Hurricane.Net.Type.LOGICAL
Hurricane.DirectionIN ==> Hurricane.Net.Direction.IN
* Change: In CRL Core, correction to match the improved Python API
in the configutation helpers.
* Change: In Cumulus, correction to match the improved Python API.
* Change: In Stratus, correction to match the improved Python API.
* Change: In Documenation, update for the new Python interface
(both user's guide & examples).
* Note: We must port those changes into Chams for it to continue
to run.
* Change: In Documenation, update the Python script support part.
* 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 Hurricane, in Cell::flattenNets(), do not flatten a *top net*
if at least one RoutingPad is present. In that case, we assumes that
the net has already been completly flattened.
* New: In Hurricane, in Entity, add an accessor to unique id counter.
* New: In CRL Core, in PyCellGauge, add the missing methods.
* Bug: In Isobar, PyOccurrence_create(), the HTRY/HCATCH block was not
enclosing the constructor of Occurrence, which can throw exceptions.
When an exception was thown the Python interpreter just terminate
with the cryptic message:
"Fatal Python error: Py_EndInterpreter: thread still has a frame"
Reminder to myself: when such a message occurs, it means that the
interpreter did encounter a problem, but it's related to the isobar
interface.
* Bug: In Hurricane, UpdateSession::close(), when re-materializing, the
cells must be notified <CellChanged> *after* all the Gos are
re-materializeds. In fact they must also revalided according to the
deepness of their instanciation (the deepest first). Has still to
be done.
Placement management:
* Change: In <metis>, always disable the hMetis support regardless of
it being detected or not as the placer is still unable manage the
final bin contents.
Routing gauge management:
* Bug: In CRL Core, <vsclib/alliance.conf>, set the correct pitches and
size for the routing layers and the cell gauge.
* Change: In Katabatic & Kite, extract the correct extension cap for each
routing layer from the layers characteristics (cache then in
Katabatic::Configuration).
* Change: In Katabatic, <AutoSegment>, create segment with the wire width
defined in the gauge. For AutoSegment created on already existing
Segment from the global routing, adjust the width.
* Change: In Katabatic, <AutoSegment>, more accurate information about how
a segment is connected to terminal via source and/or target.
The flag SegStrongTerminal is splitted into SegSourceTerminal and
SegSourceTarget (but still used as a mask). So now we can know by
which end an AutoSegment is connected to a terminal.
* Change: In Katabatic, ::doRp_Access(), create constraint freeing segments
not only when HSmall but also when VSmall (more critical for <vsclib>).
Otherwise we may see AutoSegments with incompatible source/target
constraints.
* Change: In Kite, BuildPowerRails, do not create blockage on PinOnly
layers *but* still create power rails planes. This is a temporary
workaround for <vsclib> where the METAL1 blockages overlaps the
terminals (it was fine for Nero, but they shouldn't for Kite).
* Change: In Kite, <RoutingEvent>, if a TrackSegment is overconstrained,
directly bybass it's slackening state to DataNegociate::Slacken.
Also rename the flag "_canHandleConstraints" to "_overConstrained",
seems clearer to me.
Miscellaneous:
* Change: In CRL Core, <Utilities>, add a "pass-though" capability on the
mstream to temporarily make them print everything.
When upgrading from doxygen 1.5.x to 1.8.5 the way the documentation
is generated has underwent many changes, particularly in the headers.
* Change: In <header.html>, must include the javascripts <jquery.js>
and <dynsections.js>.
* In <CMakeLists.txt>, as the header is customized, doxygen seems not
copy some files like the javascripts and some images (open.png,
closed.png). So we copy them from doxygen installation and make
the CMakeLists.txt install them. I hope they will not change too
much in the future.
* In <doxyfile>, disable markdown support as it do not interpret
correctly the formating we already adopted (with a left margin
to put command into). Use HTML_EXTRA_STYLESHEET instead of
HTML_STYLESHEET. Enable the index (DISABLE_INDEX=NO), for the
top header. Enable dot for inheritance diagram. Set the
EXAMPLE_PATH=. to include the synthetic hierarchy.
Correct the tag inclusion (faulty path in some places).
* In <SoC.css>, create style for the new header generated by doxygen.
* In the documentation, move the synthetic hierarchy into a module.
Miscellaneous:
* Change: In <crlcore>, in display.conf use the same display threshold
for both METAL2 & METAL3.
In alliance.conf, the side of VIAs in the gauge is 2l (not 3l).
In kite.conf, separate edge densities for H/V.
* Change: In <Cell>, in flattenNets() use flag as argument, not a
boolean. Do not create rings for clock or supply nets.
* Change: In <DeepNet>, in _createRoutingPads() do not create rings
for clock or supply net (duplicated policy as in Cell::flattenNets()).
* Bug: In <ControllerWidget>, at last find the bad signal disconnect
that was causing ungraceful messages.
* Change: In <knik>, in Edge display occupancy/capacity in the string
name. Improved display progress and debugging capabilities.
Improved exception catch & breakpoint managment:
* Bug: In <PaletteWidget>, in updateExtensions() replace the calls to
deleteLayer() by delete. This cause the widget to be immediatly
erased instead of waiting for the event queue to be completly
processed. This was causing the widget to be left in a incoherent
state when stoping at a breakpoint.
* Bug: In <BreakpointWidget>, in execNoModal(), flush the main event
loop (QApplication::flush()) *before* lauching the *local* event
loop. This is to ensure all widgets are in their final state when
waiting (especially <PaletteWidget>).
* Change: In <ExceptionWidget>, new method catchAllWrapper() to
execute any std::function< void() > function/method with a "try"/
"catch" wraparound and lauch the widget in case something is catch.
* New: In <hurricane>, support for a oberver pattern, backported from
<katabatic> with an Obervable capable of being linked to any
number of Obervers.
* New: In <Cell>, made it observable to detect Cell change, currently
emit two kind of signals:
- Cell::CellAboutToChange : *before* any change.
- Cell::CellChanged : *after* the change has been completed.
* New: In <UpdateSession>, in Go::invalidate() add the Cell owning the
Go to the UPDATOR_STACK (of course the cell is added only once).
In addition, when the Cell is added, send a notification of
Cell::CellAboutToChange to all it's observers. The slave instances
are also invalidated.
Conversely in UpdateSession::_preDestroy() for each invalidated
Cell send a Cell::CellChanged notification to all observer.
The UPDATOR_STACK has been slightly amended to accept Cell which
are not Gos. Prior to this, the Cell where completly excluded from
the UpdateSession mechanism, so it's instances where never actualised
of anything referring to the Cell for that matter.
Note: we use two different mechanisms to transmit a Cell change,
observers and the slave instance map. I think at some point it
should be unificated.
* Change: In <CellViewer>, make it a Cell observer to redraw when the
cell is modificated (also update the palette).
Uses the catchAllWrapper() to protect all critical actions.
* Change: In <GraphicTool>, no longer need of cellPreModificated and
cellPostModificated signals. Now done through the Cell obersvers.
* Change: In <mauka>, <etesian> & <kite> now uses the catchAllWrapper
method for protection (need to split methods in two, to be able
to pass it as argument). No longer emit cellPreModificated and
cellPostModificated.
Support for RoutingGauge in P&R:
* Bug: In <placeandroute.py>, the connection from the internal power
ring to the connectors was not done correctly. Wrong contact layers
leading to a gap.
* Change: In <BuildPowerRails>, detection of the corona signals based
on how the "pck_px" pad is connected. No longer based on name
matching.
* Change: In <placeandroute.py>, support for 2 routing metal only
(3 metal in the technology).
* Change: In <katabatic> & <kite> support for a "top layer" limitation
on the routing gauge, this allows to use only two routing metals
(METAL2 & METAL3). Work in progress.
Cleanup:
* Cleanup: In <vlsisapd/src/bookshelf>, remove unused file Bookshelf.cpp
(may have been a parser once upon a time).
* Cleanup: In <hurricane>, in Cell::flattenNets() use flags instead of
booleans to be more readable. Allow occurrence placement checking.
* New: In <crlcore> add Python wrapper for the Ispd05 loader.
* New: In <unicorn> add option for direct loading of ISPD05 designs.
* Bug: In <hurricane/src/viewer>, RecordModel must emit
layoutAboutToBeChanged() before changing the record contents (and
layoutChanged() afterwards).
Details:
* New: In <vlsispad/utilities>, new objet Dots for displaying a kind
of progress bar.
* Change: In <vlsisapd/bookshelf>, keywords are now case-insensitive.
Added a "strict syntax" option (to be disabled for ISPD05).
* New: First working implementation of Etesian, at least for ISPD05
"bigblue1".
* Change: In <hurricane>, in Cell::flattenNets(), no longer display
a warning if an instance is unplaced, this does not make sense
when the circuit is not placed.
* New: In <crlcore>, Added translator for ISPD05 bookshelf, the
circuit is *not* placed, unlike in ISPD04 and terminal nodes
*are* true cells.
* New: In <unicorn>, added entry in import cell for ISPD05 benchmarks.
