* Change: In Hurricane::Cell_LeafInstanceOccurrences, add the ability to
walkthrough the leaf of one specific top-level instance.
* Change: In Hurricane::Cell_NonLeafInstanceOccurrences, add the ability to
walkthrough the leaf of one specific top-level instance.
* Change: In Hurricane::Cell:
getLeafInstanceOccurrences() and getNonLeafInstanceOccurrences(), now
have a parameter Instance* to select the leafs we want to walk through.
If set NULL (default value) browse through all the instances,
as before.
* Change: In Hurricane::DeepNet, add forgotten Inspector support.
* New: In EtesianEngine, add a "block" (and Instance) attribute to allow
the placement of one specific bloc. If we want to place the core of
a chip and take into account the external terminals (if they are not
already fixed as Pins at the edge of *said* block). We must place
the core *in the context* of it's instanciation in the corona.
Note for G. Gouvine : Pin & external RP should be taken into account
starting at line 629 of EtesianEngine.cpp...
* New: In cumulus/plugins/chip/Chip.py, make use of the new block
placement feature of ETesian.
* Bug: In KatanaEngine::create(), perform a pre-check to prevent trying to
route whole chip, which is forbidden an leads to annoying core-dumps.
Routing must take place "at most" at Corona level.
* Bug: In KatanaEngine::PowerRails, create a plane for METAL1 blockage.
Not completely sure this was a bug...
* Change: In Hurricane::SharedName, replace the incremental Id by a hash key.
This is to ensure better deterministic properties. Between use cases,
additional strings may have to be allocated, shitfing the ids. Even if
hash can be duplicated, we should be able to ensure that the absolute
order in map table should be preserved. Supplemental strings are inserted
in a way that keep the previous order.
* Change: In CRL/etc/symbolic/cmos/kite.conf, add "katabatic.routingGauge"
default parameter value ("sxlib").
* Change: In CRL/etc/common/technology.conf, define minimal spacing for
symbolic layers too (added for METAL4 only for now).
* Change: In CRL::Histogram, extend support to dynamically sized histograms.
Add a text pretty print with table and pseudo-curve.
* Change: In Cumulus/plugins/ClockTreePlugin, create blockage under the
block corona corners so the global router do not draw wire under them.
This was creating deadlock for the detailed router.
When the abutment has to be computed, directly use Etesian to do it
instead of duplicating the computation in the Python plugin.
* New: In Etesian, as Coloquinte seems reluctant to evenly spread the
standard cells, we trick it by making them bigger during the placement
stage. Furthermore, we do not not uniformely increase the size of the
cells but create a "bloating profile" based on cell size, cell name
or it's density of terminals. Currently only two profiles are defined,
"disabled" which does nothing and "nsxlib" targeted on 4 metal layer
technologies (aka AMS 350nm, c35b4).
* Bug: In Knik::MatrixVertex, load the default routing gauge using the
configuration parameter "katabatic.routingGauge" as the default one
may not be the first registered one.
* New: In AnabaticEngine::setupNetDatas(), build a dynamic historgram of
the nets terminal numbers.
* Bug: In Anabatic::AutoContact::Invalidate(), always invalidate the
contact cache when topology is invalidated. In case of multiple
invalidations, if the first did not invalidate the cache, later one
that may need it where not allowed to do so. The end result was correct
nonetheless, but it did generate annoying error messages.
* Bug: In Anabatic::AutoContactTurn::updateTopology(), bad computation
of the contact's depth when delta == 2.
* Bug: In Anabatic::Gcell::getCapacity(), was always returning the west
edge capacity, even for the westermost GCell, should be the east
edge in that case.
* New: In Anabatic::AutoSegment, introduce a new measure "distance to
terminal". This is the minimal number of segments separating the
current one from the nearest RoutingPad. This replace the previous
"strong terminal" and "weak terminal" flags.
This distance is used by Katana to sort the events, we route the
segments *from* the RoutingPads *outward*. The idea being that if we
cannot event connect to the RoutingPad, there is no points continuing
as thoses segments are the more constraineds. This gives an order close
to the simple ascending metals but with better results.
* New: In Anabatic::AutoSegment, introduce a new flag "Unbreakable", disable
dogleg making on those segments. mainly intended for local segments
directly connecteds to RoutingPads (distance == 0).
* New: In Anabatic::AutoSegment, more aggressive reducing of segments.
Now the only case where a segment cannot be reduced is when it is
one horizontal branch in a HTee or a vertical on a VTee. Check if,
when not accounted the source & target VIAs are still connex, if so,
allow reducing.
* New: In Anabatic::AutoContact, new state flags CntVDogleg & CntHDogleg
mainly to prevent making doglegs twice on a turn contact. This is to
limit over-fragmentation. If one dogleg doesn't solve the problem,
making a second one will make things worse only...
* Bug: In Anabatic::Configuration::selectRpcomponent(), we were choosing
the component with the *smallest* span instead of the *bigger* one.
* New: In Anabatic::GCell, introduce a new flag "GoStraight" to tell that
no turn go be made inside those GCells. Mainly used underneath a block
corona.
* New: In AnabaticEngine::layerAssign(), new GCellRps & RpsInRow to manage
GCells with too many terminals. Slacken at least one RoutingPad access
when there is more than 8 RoutingPad in the GCell (slacken or change
a vertical METAL2 (non-preferred) into a METAL3).
* Change: In Anabatic::NetBuilderHV, allow the use of terminal connection
in non-preferred direction. That is, vertical METAL2 directly connected
to the RoutingPad (then a horizontal METAL2). This alllows for short
dogleg without clutering the METAL3 layer (critical for AMS c35b4).
Done in NetBuilderHV::doRp_Access(), with a new UseNonPref flag.
Perform some other tweaking on METAL1 access topologies, to also
minimize METAL3 use.
* New: In AnabaticEngine::computeNetConstraints(), also compute the
distance to RoutingPad for segments. Set the Unbreakable flag, based
on the distance and segment length (local, short global or long global).
New local function "propagateDistanceFromRp()".
* Change: In AnabaticEngine.h, the sorting class for NetData, SparsityOrder,
is modificated so net with a degree superior to 10 are sorted first,
whatever their sparsity. This is to work in tandem with GlobalRouting.
* New: In Katana::TrackSegmentNonPref, introduce a class to manage segment
in non-preferred routing direction. Mostly intended for small METAL2
vertical directly connected to RoutingPad. Modifications to manage
this new variant all through Katana.
* Change: In Katana::GlobalRoute, DigitalDistance honor the GoStraight flag
of the GCell. Do not make bend inside thoses GCells.
* Change: In KatanaEngine::runGlobalRouter(), high degree nets (>= 10) are
routed first and whitout the global routing estimation. There should be
few of them so they wont create saturations and we want them as straight
as possible. Detour are for long be-points.
Set the saerch halo to one GCell in the initial routing stage (before
ripup).
* Bug: In KatanaEngine & NegociateWindow, call _computeCagedconstraints()
inside NegociateWindow::run(), as segments are inserted into tracks
only at that point so we cannot make the computation earlier.
* Change: In Katana::Manipulator::repackPerpandiculars(), add a flag to
select whether to replace the perpandiculars *after* or *before* the
current segment.
* Change: In Katana::NegociateWindow::NegociateOverlapCost(), when the
segment is fully enclosed inside a global, the longest overlap cost
is set to the shortest global hoverhang (before or after).
When the cost is for a global, set an infinite cost if the overlapping
segment has a RP distance less or equal to 1 (this is an access segment).
* Bug: In Katana::PowerRailsPlane::Rail::doLayout(), correct computation of
the segments extension cap.
* New: In Katana::QueryPowerRails::addToPowerRail(), add support for Pad.
* Change: In Katana/PreProcess::protectCagedTerminals(), apply the contraints
to any turn connected to the first segment of the RoutingPad so the
perpandicular constraints got propagated to the perpandicular segment...
* Change: In RoutingEvent, cache the "distance to RP" value.
* Change: In RoutingEvent::Key::compare(), sort *first* on distance to
RoutingPad, then layer depth. If both distance to RoutingPad is null,
then sort on segment length.
* Change: In RoutingEvent::_processRepair(), try a repack perpandicular with
perpandiculars first (then with perpandicular last, then give up).
* Change: In SegmentFsm::bindToTrack() and moveToTrack(), set an axis hint
when creating the insertion event.
* Change: In SegmentFsm::_slackenStrap(), add a step through slacken between
minimize and maximum slack (wihch directly end up in unimplemented).
* Change: In Session::_addInsertEvent(), add an axis parameter needed when
the axis of the segment is not the one of the track (case of wide
segments or non-preferred direction).
* Bug: In Track::_preDestroy(), bad management of the TrackElement reference
count. Destroy the segment only when reaching zero...
* Bug: In Track::expandFreeIneterval(), forgotten to manage case when there
is a set of overlaping segments at the "end" of the track, the
EndIsTrackMax was not set.
* Change: In TrackCost::Compare, increase the cost when an overlaping
segment is at it's ripup limit. We should try *not* to rip it up if
we can. Add a dedicated flag "AtRipupLimit".
* Change: In TrackElement, add proxies for isUnbreakable(), new function
updateTrackSpan().
* New: In TrackFixedSegment CTOR, when a supply wire of METAL2 or above is
found, make the underlying GCells "GoStraight".
* New: In TrackElement::canDogleg(GCell*), check for already done perpandicular
dogleg on source/target (reject if so).
* Bug: In Hurricane::DrawingQuery::drawGo(), forgot to apply translation
on Polygon and Rectilinear.
* Bug: In Hurricane::Rectilinear, forgot implementation of getContour().
Add a new accessor getPoints().
* Bug: In CRL::Blif::load(), do not always enforce translation towards
VHDL names. When loading LEF+gds it may change the Cell names between
the two stages so the gds layout do not get added to the LEF Cell
phantom.
Now add a boolean enforceVhdl argument (may be a flag in the future).
* Bug: In ::GdsStream::operator<<(Cell*), forgot to drive the Rectilinear.
* 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.
* 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...
* Bug: In CRL Core, in VectorPortMap::VhdlPortMap(), if the connection
was made to *non-contiguous* bits of an otherwise *contiguous* vector,
it was using a span instead of the separate bits. Now check that
bits are contiguous (delta: +1/-1) and the delta do not change of
sign.
* Change: In Etesian & Kite, the Python interface function ::setViewer()
was checking that the argument was indeed a CellViewer, but in text
mode it is None. Now, silently ignore the argument if it cannot be
converted into CellViewer.
* 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.
* 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.
* 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).
Update to Qt 5:
* Change: Now requires at least cmake 2.8.9.
* Change: CMakeLists.txt needs small changes. Qt modules must be found
one by one (Core, Gui, Widgets). Must add "set(CMAKE_AUTOMOC ON)"
in the top file and replace "qt4" prefix in macros by "qt5".
Added simpler macro "setup_qt()" in FindBootstrap.cmake.
* Change: No longer need to include <QGtkStyle> is is choosen by default
according to the current desktop environment.
* Change: In <hurricane>, In HApplication, launch ExceptionWidget when
a std::exception is catched instead of silently discarting it.
New placer Tool: Etesian
* New: <etesian> analytical placer. Encapsulate Coloquinte from
Gabriel Gouvine.
* New: in <documentation>, add stub demonstration ToolEngine <smurf>.
Needs to be commented.
Miscellaneous:
* New: in <boostrap> and <unicorn>, added support for Etesian, the new
analytic placer. The tool itself will be added in the next commit.
* Bug: in <CellWidget>, when shifting the display buffer, we no longer
can copy the buffer on itself (we should never have). Now go through
a temporary one (PlaneId::AutoCopy) which is added to the
DrawingPlanes. Affect "goLeft()" and "goUp()".
* Bug: In <CellWidget>, remove the WA_PaintOnScreen flag/attribute.
When it's on, no PaintEvent is transmitted to the CellWidget
when it's the central widget of the <CellViewer> (QMainWindow).
It's something I still don't understand from the doc of Qt.
* Change: In <AreaCommand>, use the PlaneId enumeration instead of a
anonymous numerical index.
* Change: In <HApplication>, no longer catch and silently discard
standartd exceptions but launch the ExceptionWidget...
Suppress the now deprecated constructor with "Type" argument.
* Change: In <SelectionModel>, the "reset()" method is deprecated in
Qt5, instead enclose the "clear()" by a "beginResetModel()" and
"endResetModel()" pair.
* New: In <crlcore>, add support for ISPD05 benchmarks (in Bookshelf
format). Forked from ISPD04 and not finished yet.
* Change: In <Mauka>, distinguish the Action string identifier from
<Etesian>
* New: In <unicorn>, add entry for ISPD05 loader. Add entry for
<Etesian> analytic placer.
