* New: In Isobar::PyCell, export the isRouted() and setRouted() to the
Python interface.
* Bug: In CRL::Entity::parseEntity(), check that the closing parenthesis
is the last character of the net name. Issue a more relevant error
message.
* In Anabatic::NetBuilder::_do_xG() and all other unimplemented methods,
throw an error if called from a derived classes instead of just
issuing a message in the debug stream. Avoid later core dumps...
* In Anabatic::NetBuilderHV, implement the builders for GCells with
one pin. Needed to support chip/corona routing.
* Bug: In Cumulus/plugins/Chip.py, check that coronaCk exists before
using it.
* New: In Cumulus/plugins/PadsCorona/Side._placePad(), when routing
a design with symbolic pads, export the chip external "pad"
connectors to be able to perform a lvx (otherwise cougar do not
create external nets).
In Corona._createCoreWire(), set the minimal gap between the pads
and the corona to 6 pitches. Empirical value to avoid DRC errors
with symbolic pads (pxlib).
When successufully done, mark the Corona cell as routed.
* Bug: In Cumulus/plugins/Core2Chip.IoNet, the regex for vectorizet net
was wrong, it was allowing only one digit in the index.
* Bug: In Cumulus/plugins/Core2Chip.cmos, correct management of
pad & corona clock nets. Correct connexion between vdde/vddi.
* Bug: In Unicorn/cgt.py, forgot to execute scripts when in text mode.
* Change: In Hurricane::Error constructors disable the backtrace generation.
(*very* slow).
* Change: In Hurricane::Library::getHierarchicalname(), more compact
naming. Remove the name of the root library.
* New: In Hurricane::Net, new type "FUSED", for component with no net.
More efficient than having one net for each.
* Change: In CellViewer, BreakpointWidget, use Angry Birds icons.
* Change: In CellWidget::State, use the hierarchical name (cached) as key
to the state. This allow to load two cells with the same name but from
different libraries in the widget history.
* Change: In PyGraphics, export "isEnabled()" and "isHighDpi()" functions.
* Change: In CRL/etc/symbolic/cmos/plugin.conf, and
CRL/etc/common/plugin.conf use the physical dimensions converters.
* Change: In CRL/etc/symbolic/cmos/technology.conf, make the GDS layer
table coherent with the default Alliance cmos.rds.
* New: CRL/python/helpers/io.py, put ErrorMessage new implementation here,
along with a new ErrorWidget written in PyQt4. It seems finally that
PyQt4 can be used alongside Coriolis Qt widgets.
New ErrorMessage.catch() static function to manage all exceptions
in except clauses.
* Change: In CRL/python/helpers/, no longer use ErrorMessage.wrapPrint(),
directly print it.
Rewrite the utilities to display Python stack traces "textStacktrace()"
and "showStacktrace()".
* Change: In CRL::AllianceFramework, shorten the names of the libraries.
* Change: In CRL::ApParser & CRL::ApDriver, more accurate translation between
Alliance connectors (C record) and Hurricane::Pin objects. Pin are no
longer made square but thin and oriented in the connecting direction.
Use the new fused net for unnamed components.
* New: In CRL::GdsParser, implementation of SREF parsing, i.e. instances.
Due to the unordered nature of the GDS stream, instances creation are
delayed until the whole stream has been parsed and only then are they
created.
For the sake of reading back Alliance s2r GDS, we assume that any
TEXT following a boundary is the Net name the boundary (component)
belongs to.
Create abutment box for Cells, computed from the bounding box, so
the Hurricane QuadTree could work properly.
Make use of the fused net for unnamed components.
* New: In Cumulus/plugins/chip, complete rewrite of the I/O pad management.
Now we can mix real (foundry) pads and a symbolic core.
To cleanly support the de-coupling between the real part and the
symbolic one we introduce a new intermediary hierarchical level, the
corona. We have now:
Chip --> Pads + Corona --> Core.
At chip level (and if we are using real pads) the layout is fully
real (excepting the corona).
The Corona contains everything that is symbolic. It has symbolic
wires extending outward the abutment box to make contact with the
real wires coming from the pads.
In the pad ring we can use corners instances (or not), pad spacers
or directly draw wires between connectors ring pads.
Provide two flavors: placement only or full place & route.
WARNING: If routing in a second step, *do not route* the *Chip* but
the *Corona*.
* Change: In Cumulus/plugins/clocktree, give the modified Cell an
additional extension of "_cts" (Clock Tree Synthesis) instead of
"_clocked", to follow the common convention.
* New: In cumulus/plugins/S2R.py, encapsulate call to Alliance S2R and
reload the translated Cell in the editor.
* New: In cumulus/plugins/core2chip, provide an utility to automatically
create a chip from a core. To work this plugins must have a basic
understanding of the pad functionalities which may differs from
foundry to foundry. So a base class CoreToChip is created, then for
each supported pad foundry a derived class is added. Currently we
support AMS c35b4 and Alliance symbolic cmos.
* Bug: In Anabatic::Configuration, read the right configuration parameter
"anabatic.topRoutinglayer" (Katana), and not the one for Katabatic...
* Change: In Unicorn/cgt.py, process the plugins in alphabetical order
to ensure a reproductible ordering of the menus...
* Change: In Hurricane::CellViewer, reorganisation of the to level menus.
Add "Misc." and it's two sub-menus "Beta" and "Obsolete".
* Change: In GraphicKiteEngine::addToMenu(), set Kite in the obsolete menu.
* Change: In GraphicKatanaEngine::addToMenu(), set Katana as the standart
router.
* Bug: In Hurricane python module, forgot to add the Segment type.
* Change: In Isobar/layer.getEnclosure() wrapper check and cast the Layer
argument into BasicLayer.
* Change: In CRL::RoutingGauge::getLayerGauge(Layer*), getLayerType() and
getLayerDirection() no longer check layer identity based on layer
mask instead of just Layer* pointer. To allow a unified call wether
the layer is real or symbolic.
* Change: In CRL::RoutingLayerGauge::getTrackIndex() and getTrackPositon(),
no longer consider negative indexes as invalid and reset them to
zero. The check for out of bound index is now left to Anabatic &
Katana.
* Change: In CRL/RoutingGauge.getRoutingLayer() and getContactLayer(),
more detailed error message.
* Change: In CRL/RoutingLayerGauge.getTrackIndex() and getTrackPosition(),
indexes are now signed long instead of unsigned.
* Bug: In Hurricane::Cell::flattenNets(): Same error again, do not create
components while iterating over the components Collection.
Now RoutingPad of top nets are create outside the loop as they must.
* New: In Hurricane::IntrusiveMap, introduce IntrusiveMapConst which allow
to search with a "const Key&" instead of a "Key", sparing the copy
construction of the Key.
* Change: In Hurricane::Cell::NetMap, use the new kind of map with
"const Name&" key access. This speeds up the Cell::getNet() method
by suppressing one copy construction of a Name, which are costly
after all...
Should review the whole code to use "const Name&" everywhere it
is possible.
* Change: In Hurricane::Entity & Hurricane::DBo, displace the unique
identifier from Entity to DBo (move up to the base class).This
to allow us to build deterministic map of DBo requireds in
UpdateSession (which is built upon a SharedProperty).
WARNING: This break the JSON database exportation support, do not
use it until fixed/rewritten.
* Change: In Hurricane::Layer, add an attribute to know if a layer is
associated to a blockage. Modificate accordingly PyLayer and
BasicLayer.
* Change: In Hurricane::SharedProperty, the set of owners (DBo*) is now
stored in a std::set sorted on the objects Ids, instead of a simple
vector. The linera search time through the std::vector was starting
to show (ISPD05 bigblue1).
* Bug: In Isobar::PyInstance, make full contructor signature (5 arguments)
conform to the C++ one. It was only accepting the four first and
forcing the placement status to be FIXED.
* Bug: In CRL/etc/symbolic/ispd05/kite.conf, update for the new configuration
requirements where all distance must be converted into DbU in the
file itself (use "helpers.l()", "helpers.m()"). Apply to the cell &
routing gauges.
* Bug: In CRL/etc/symbolic/ispd05/technology.conf, update for the new
configuration. "helpers.initTechno()" *must* by called first thing
in this file in order for the Technology to be created.
* New: In CRL::AllianceFramework, add matchCellGauge() &
matchCellgaugeByHeight()
* New: In CRL::CellGauge, add a flag to distinguish gauges meant for
IO Pads and an "isPad()" predicate.
* Change: In CRL::Ispd05Bookshelf, flush the UpdateSession stack every
1000 elements additions. Maybe not necessary now the the UpdateSession
property relies on a std::set instead of a std::vector.
* New: In CRL::LefImport, support for SITE and match/create the appropriate
CellGauge on the fly. Specific support for MACROS that are flagged PAD.
Add a dedicated post-treatment for PAD connectors, extend them toward
the boundary of the nearest abutment box side. Tested only on AMS 350nm
c35b4 for now.
This part is most likely to be tweaked for every kind of real foundry
pad that we may encounter...
* Change: In EtesianEngine::findYSpin(), use the C++ "for" construct to loop
over Collections.
* Change: In Unicorn/cgt.py, register the Python/C++ tutorial support by
default.
* Bug: In Hurricane::Collection::iterator, the iterator use a locator from
a getLocator() not wrapped inside an auto_pointer like GenericLocator.
So the destructor of the iterator must take care of the deletion.
This was showing more and more as we converted forEach() into the
C++ 11 for syntax.
Seems to decrease the memory use by almost a factor 2...
* Bug: In Dijkstra::_cleanup(), as a double security, cleanup the queue.
* New: In Hurricane::Isobar::PySegment, added wrapper for getOppositeAnchor().
* Bug: CRL::PyRoutingLayerGauge, Python wrapper of getTrackPosition() was
in fact returning getTrackNumer().
* Bug: In Katana::PowerRailsPlanes::Rail::doLayout(), add the half minimum
distance to the blockage segments extensions. Was causing too near
VIAs is cmos45.
* Change: In cumulus/plugins/ClockTree, correctly manage routing gauge when
the lower pitches (M2/M3) is different from the upper one (M4/M5).
But we still can only do sxlib compliant gauges because we do not
handle a switch in preferred routing directions.
* 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.
* Bug: In hurricane/Technology.h we define a set of UnitRule with a
custom sorting function. STL starting with gcc 8, introduce a type
checking of the compare function. And as everithon is template, we
must use the exact key type and no longer a base type... So we create
an overload for each derived type :-(
* Change: In Hurricane::Cell::NetMap, the hash function is now based on
the string itself and not on the id of the SharedName. We now may
remove the id attribute of the SharedName.
This to ensure a more robust deterministic behavior. The sort
order do not depend on whether we did use names before or not.
* Change: In Hurricane::CellWidget, new "isPrinter" attribute to know if
the CellWidget is used as a device for printing.
New function copyExtensionsGos() to duplicate the ExtensionGo drawing
callbacks. This is a temporary hack until the ExtensionGo are made static
to be shared by all CellWidgets.
In _redraw(), the DrawingQuery flags were not correctly reset between
different stage of the drawing. This was resulting of uneeded walkthough
of the slicing tree, along with incorrect display of some of the layers
(i.e. rubbers where diplayeds when ExtensionGos where active).
* Change: In GraphicKatanaEngine, fine tune the display of GCells for printing
CellWidget.
* Change: In Hurricane::CellPrinter, copy all the settings from the palette
of the reference (graphic) CellWidget into the printer CellWidget.
Also copy the ExtensionGos callbacks so we can print them. Use the
new CellWidget attribute "isPrinter" for the callbacks to be able
to adapt to Printer settings.
* Change: In Hurricane::Time::getStringTime(), only print two decimals
for time durations.
* New: In Hurricane::RbTree, template for red-black tree. Standard
implementation but well integrated in the Hurricane database and
ready to be derived (both iterator and Collection support).
* New: In Hurricane::IntervalTree, template for interval tree, derived
from RbTree.
* New: unittests tool to perform unit tests.
* Change: In Bora::ChannelRouting, now implemented with IntervalTree.
There is something suspicious here : the "thick" version of
addWireoccupation() seems never to be called. Have to check the
wide wire support implementation.
* Change: In Hurricane::CellWidget, set the minimal size to 350 pixels
to fit my normal DPI secondary screen...
* Change: In Hurricane::Error(), reactivate the backtrace generation by
default. Seriously slow down the program each time an Error is to
be constructed.
* Bug: In Analog::Device::preCreate(), check for NULL Technology before
attempting to use it.
* Change: In Hurricane/Analog, remove all '*Arguments*' classes and their
Python interface. It was an obsoleted way of passing devices parameters
to the Python layout generators (located in Oroshi). Now we just get
them straight from the Device with the getParamter() method.
* Change: In CRL::System CTOR, add Python pathes for Oroshi & Karakaze.
* Change: In Oroshi/Python/WIP_*.py layout generator scripts, remove
all uses of the "Arguments". Directly access the parameters through
the device itself. Make the checkCoherency() with identical arguments
as of layout().
* New: Bora tool that performs analog place & route. Based on a slicing
tree representation. It is the thesis work of Eric Lao.
Code beautyfication and some programming cleanup.
* New: Karakaze tool, provide the Python base class AnalogDesign used
to build an analog design. Create/configure devices and assemble
them in a slicing tree.
* Change: In Unicorn/cgt.py, display the stack trace in case of an
ImportError exception as well as for other exceptions.
Add Bora to the set for included tool engines.
* Change: In boostrap, remove support for Chams.
* New: In Hurricane::Technology, added support for DTR rules, UnitRule,
PhysicalRule and TwoLayersPhysicalrule. Added devices descriptors and
models descriptors (for Spice). Spice description is not used yet
but kept anyway in case of future use.
* New: Hurricane::Analog whole library and it's Python interface. This
provides support for transistors, capacitors and resistors. Only
transistor support is fully implemented as of now.
* New: In CRL/python/coriolisInit.py, read configuration files for the
Analog extension (analog.conf & devices.conf). Thoses are optionals
and a simple warning is issued if not found.
Added helpers/AnalogTechno.py DTR loading helper.
Add analog configuration files for 180/scn6m_deep_09.
* New: Oroshi tool that provides actual layout drawing for transistors.
* Problem: In LEF/DEF, the parsers makes use of the libc "strtod()" which
is now localized. So, if your environment is set up for French, the
decimal separator is not '.' (dot) but ',' (comma). So floating
numbers in LEF/DEF file are not longer recognized as such, causing
the parsers to fail with a LEFPARS-1 error.
To avoid that, we force the LC_ALL environment variable to POSIX
in Hurricane::DataBase::create(). So first things that happens when
Hurricane starts, is the environment to be reset.
Strangely, when I try to setup only LC_NUMERIC with setlocale()
it doesn't work. There is something I'm missing there...
* Change: In CRL::GdsStream, no longer export empty Cells as structures,
to avoid empty cells in Cadence. To prevent meta-transistors to be
exported as real physical objects.
Also put a hard-coded test to prevent exporting "control_r" model
which is made of AMS standard cells for "amsOTA".
* Change: In CRL/PyRoutingGauge, export the isHV() and isVH() methods so
the Stack can access it.
* Change: In Hurricane/PyCellViewer, export the removeHistory() method.
When a Cell is deleted, it must be also removed from the editor
history. This should be take care of automatically, but for now
we make it manually through scripts.
* Bug: In Anabatic::NetBuilder::doRp_accessAnalog(), the gauge offset
was not taken into account when creating initial Contact on
RoutingPad. The program self corrected afterwards, but with the
display of a disgraceful message.
* Change: In Anabatic::Configuration and Session, export the gauge offsets.
The short net mode degrade the routing in some cases. This will be
fixed in a next batch of commits.
* New: In Hurricane::NetRoutingProperty, added "ShortNet" flag for Nets
that are completly inside *one* GCell.
* Bug: In CRL::BlifParser::Model::staticInit(), when looking for the
output of zero and one cell, also skip the blockage net (as well as
automatic and supplies).
* New: In Anabatic::AutoSegment, added "ShortNet" flag to know if the
segment is part of a short net (fully included in *one* GCell).
Also add accessor/mutators for the _analogMode flag (was it ever
used before?).
* New: In Anabatic::NetBuilder::singleGCell(), if a RoutingPad is
vertically small, add a vertical segment to give it some slack.
* New: In Anabatic::Dijkstra::_materialize(), detect "short net" as
they have only one GCell in their source list...
* Bug: In AnabaticEngine::_loadGrbyNet(), reset the AutoSegment
"short net" and "analog mode" creation flags between two different
nets.
* New: In Katana::Configuration, added dedicated ripup for short net
segmnts.
* New: In Katana: partially implemented support for "short dogleg", that
is dogleg that are always kept in same metal because they connect
neighboring perpandicular tracks. Not finished neither activated
yet.
* New: In Katana::TreckElement and derived, export the the *short net*
support from AutoSegment.
* Bug: In Katana::RoutingEvent::_processRepair(), when a segment is
successfully inserted, re-process any perpandicular that is in
repair state, as it may have a new chance to be placed.
* New: In Katana::SegmentFsm::slackenTopology(), always reject short nets.
* Bug: In Katana::Track::check(), correctly handle wide segments instead
of issuing false check messages.
* Change: In all tools supplying documentation, as we use some specific
software to create the doc, they may not be available, or worse, be
and incompatible version. So, by default, we install the files shipped
with the git repository. To force a full doc rebuild, use the "--doc"
flag of ccb.py.
* New: In Hurricane::Isobar::PyPolygon, export the getSubPolygons()
method. Makes a list of list (maybe tuple should have been better
to prevent user's rewrite).
* Change: In documentation/examples/scripts/, update polygons.py to
serve as a very basic test-bench for Polygon, manhattanhization
and sub-polygons display.
* Change: In Hurricane::Polygon, store the points so they are always
ordered in the counter-clockwise (trigonometric) direction. This
simplicificate internal computations.
* New: In Hurricane::Polygon, added getSubPolygons() methods, that
split horizontally the polygon in sub-polygons of about 1000
vertexes. This is mainly to be used by the GDSII driver to abide
to the XY 4000 points limitation.
* New: In Hurricane::Isobar, export support for Point collections so
the various contour Polygon methods can be created in the Python
interface.
* New: In CRL::GdsDriver, split the Polygons into set of sub-polygons
of less than 1000 vertexes. Use the getSubPolygons() method.
* Change: In stratus1.dpgen_RF2, makes more explicit error messages
about placement by displaying the faulty vs. expected coordinates.
* New: In CRL, implement a GDSII parser. The complete syntax is supported,
but only a few subset is really taken into account. It is intended to
load the layout of standard cells only. The interface of the cell is
provided through a LEF file and it complete layout through the GDSII.
The loader work in a Library way. It takes a Hurricane library as
argument and search in the GDSII library structures with a name
matching the Cell of the library and complete them.
* Change: In Hurricane::Component, put the Contour methods at Component
level so we can use them in a generic way in the CellWidget drawing
primitives.
* New: Hurricane::Rectilinear polygon, for small rectlinear polygons.
Should be less than 100 vertexes. For bigger ones, use Polygon
which allows slanted egdes.
* Bug: In CRL, freepdk_45/technology.conf, there seems to be an incoherency
bettween the GDSII layer numbers as defined in the Cadence FreeePDK45.tf
file and the one used in the supplied layout of the GDSII cells.
For now, we align on the GDSII cells to get nice layouts, but it
has to checked.
* New: In CRL, implement a true GDSII driver. The driver is directly under
CRL and do not use an intermediate structure in vlsisapd. The ASCII
GDSII is removed.
Huge polygons are not supported yet. Have to be split up in
sub-polygons of less than 4000 vertexes.
Symbolic layout can be exported to give a rough idea of the layout
but RDS expension is not applied. Symbolic composite layers are
expansed into their basic layers so the design *looks* normal.
* Deprecated: In CRL, remove all traces of the old XML configuration
parsers. No one needs them now, including Chams.
* Bug: In CRL::BlifParser, before blindly loading the model of a subckt
from disk with AllianceFramework, checks if it is in the Catalog
first. Load with AllianceFramework only cells that are in the
Catalog.
This prevent a file of the same name than a model to be loaded
shadowing the later defintion of the model in the Blif file.
All this is due to the fact that Blif could be non-ordered for
the models...
* Change: In Hurricane::BasicLayer, the "extract number" is replaced
by a GdsLayer and GdsDatatype to generate accurate GDS files.
Even if datatype is 0 most of the time.
Update all the "technology.conf" files in CRL to provide those
two numbers.
* New: In Hurricane::Diagonal, new object to represent 45° and 135°
segments (X routing). Althought they have source & target, they
are not articulated like Horizontal & Vertical, due to the
combined displacement of X and Y (diagonal).
Maybe we should create a common class for all the polygons
to make "::getContour()" a method.
Now we could represent self capacitances and high frequency
wires.
* New: Hurricane::Triange as been renamed into Hurricane::Polygon.
Add support for convex polygons. Polygon are approximateds by
excess by a manhattan rectilinear polygon (with potentially
thousands of vertexes). To reduce the memory footprint,
compaction techniques reducing by at least a factor 4 has been
implemented. We could go further by only storing the non-repetitive
part of the edge (defined by the integral fraction dY/dY).
We will see, if the program slows too much.
The manhattan approximate is always computed but displayed
only if the polygon grid step is greated than 4 pixels.
The level of approximation of the polygons can be controlled
through the "DbU::_polygonStep" parameter.
* Change: In CRL/coriolisInit.py and CRL/helpers/Technology.py, regroup
all DbU related parameters into "technoConfig" (i.e. suppress
"viewerConfig"). Update all the relevant technology.conf configuration
files.
Change the loader behavior so that "technoConfig" is read first
and is now responsible for creating the Technology of the DataBase.
* New: In Hurricane::CellWidget, added support for displaying mahanttanized
polygons.
* Change: In documenation/scripts/expample/polygons.py, perform (I hope)
a comprehensive test of the polygons (check all slopes, clockwise and
conter-clockwise).
* New: In Hurricane::DbU, added template to manage vector<> of DbU.
Support for the "polygonStep" parameter.
* Bug: In Hurricane::Cell_SubCells collection, order the set<> of Cell
with Entity::CompareById instead of pointer values.
* Bug: In Hurricane::Component_ConnexComponents::Locator, sort the
set<> of Components with Entity::CompareById instead of pointers.
* Bug: In Hurricane::Occurrence::operator<(), uses Ids to compare
both _entity and _sharedPath. Check for NULL pointers.
* Change: In Hurricane::IntrusiveMap, add a debug output in _resize()
like for IntrusiveSet.
Note to myself : despite their names, InstrusiveMap are hash
tables and not map<> in the STL sense.
* Bug: In CRL Core, Vst parser, sort the CellVectorMap on Ids.
* Bug: In CRL::NamingScheme::toVhdl(), sort the set<Cell*> models on Ids.
* Bug: In CRL::toVhdlName(), sort the set<Cell*> models on Ids.
* Bug: In CRL::getInstancesCount(), sort the map<Cell*,size_t>
gatesByMaster on Ids.
* Bug: In Hurricane::Cell::uniquify(), a set<Cell*> sorted on pointers
was remaining. Now sorted on Entity::Id.
* Bug: In CRL::VhdlEntity, in the driver, the components where driven
in pointer order (set<> again). Now use ids.
* Bug: In CRL/etc/scn6m_deep_09/technology.conf, the symbolic extentions
for VIAs and layers were wrong. Have to be multiplied by two.
* Change: In AnabaticEngine, AutoContact and AutoSegment LUTs are now
sorted on Entity::Id. Should not have had any impact, but better
safe than sorry.
* Change: In KatanaEngine, Symmetric contraint map<> is now sorted on
Entity::id. Idem for TrackSegmentLut.
* New: In Hurricane::Entity, add an id counter limit and a memory size
limit. The two limits are checked only when a new Entity object is
created. This should help avoiding massive memory links.
* New: In CRL Core, add a "crlcore.groundName" and a "crlcore.powerName"
parameter to specify the name of the ground/power signals to be
created if they are missing in a Cell. For Alliance libraries it
would be "vss" & "vdd" (default values), but for real technologies,
it is often "gnd!" & "vdd!".
The Blif parser is modificated to make use of it.
* Bug: In AnabaticEngine::unify(), set the resulting unified segment in
the center of the GCells common side. Gcells under a segment are
found by using the edge that cover the segment axis. When we have
a "bend" GCell stack and the axis is wrong, they could be ommited.
This was causing deleted segments to be not removed from some
Edges, then core dump.
* Change: In Anabatic::AutoSegment::create(), smarter choosing of the
reference contact, select the fixed or terminal one instead of
always the source one.
* New: In Anabatic::Edge::isEnding(), new function to check if a
segment going through an Edge is starting/ending in either source
or target GCell of the edge (active only when running in channel
mode).
* New: In Anabatic::Edge::add(), a segment takes part in the occupancy
only if it is not ending in either source or target (channel mode
only). The occupancy due to terminal is pre-computed in Katana.
* New: In Anabatic::Edge::ripup(), in channel mode, never ripup a
segment which is ending in either source or target (we *have* to
access this edge to connect to the terminal).
* Bug: In Anabatic::GCell::hcut() and vcut(), force the update of
the Edge which is on the side that will get splitted by the cut.
It's capacity will be reduced to it must be updated.
* Change: In Anabatic::GCell::updateGContacts() add a flag to conditionnally
update horizontals or verticals only. We may require only a partial
update when resizing the GCell in only one direction.
This, again, related to the fact that we compute the GCells under
a segment thanks to it's axis position, so we need to be very careful
when modificating axis.
* Change: In Katana::Block::resizeChannels(), only update GContact vertical
position. Do not disturb X positions of segments.
* Bug: In Katana::GlobalRoute::DigitalDistance, in channel mode, some
Edges can have a zero capacity, but still be reachable if the net has
a terminal in either source or target. Look for this case and return
a distance of zero instead of "unreachable". This was causing the
global routing not to complete in channel mode.
For computing the edge distance, makes the vertical edges much more
long (10 times) than the horizontal ones as the vertical capacity is
very limited. Hard coded for now, should make it a parameter in the
future.
* Change: In KatanaEngine::annotateGlobalGraph(), decrease the capacity
of edges with reserveCapacity for each terminal inside a GCell.
Both north and south edges are decreased as we a terminal will
block both north and south edges.
As a counterpart, the Edge capacity is not decreased when the
global router connect to a terminal.
* Change: In Katana::RoutingEvent::revalidate(), when in repair stage,
do not expand the slack for horizontal segments in channel mode.
So they may not overlap the standard cell row.
* Bug: In Stratus documentation, do not use the french option in babel,
the documentation is in english!
* New: In Documentation, added Hurricane/Python tutorial, part for drawing
layout.
* New: In Commons, inspector support for std::pair<T,U>.
* New: In Hurricane::Layer, ContactLayer & ViaLayer, support for non
square VIAs. The hole (cut) remains square, but the various metal
extensions can now be different in X and Y. The ::getEnclosure()
method now takes a flag EnclosureH / EnclosureV.
* New: In Hurricane::DbU, inspector support for:
std::pair<DbU::Unit,DbU::Unit>
std::array<DbU::Unit,3>
Must be defined here as DbU do not exists yet in Commons.h
* Bug: In Hurricane::Interval::getSize(), when the interval is "full span",
do not return the difference between min and max, but directly DbU::Max.
(the previous result was -1 !)
* New: In CRL Core Python/Technology.py, support for non square VIAs in
the configuration files. Applied to FreePDK 45.
* New: In CRL::RoutingGauge, added a "symbolic" flag to tell if a gauge
is for symbolic layout or not. Exported to Python.
* New: In Anabatic::AutoHorizontal::updatePosition(), differentiated
computation for soure or target taking account of the VIA extension
in the right segment metal (due to non-square VIAs).
* Change: In Anabatic::AutoHorizontal::_makeDogleg(), the dogleg is
UP for HV gauges and DOWN for VH.
* New: In Anabatic::AutoSegment::_initialize(), create a cache of the
various extension length for each layer (viaToTop, viaToBottom,
viaToSame).
New implementation of getExtensionCap() using the previous cached
extension table. See updatePositions().
New static functions to access the extension cache in the header:
getViaTotopCap() ...
* Change: In Anabatic::AutoSegment, in various update methods, updateOrient()
must always be called *before* updatePositions() as extensions are
dependant on source/target.
* New: In Anabatic::AutoSegment::getEndAxes() compute the position of the
first source and last target position (center/axes) on an *aligned*
set of segments.
* New: In Anabatic::AutoSegment, add a new state flag SegAxisFixed to
signal segments that can be put on only one track. Specific case
to VH gauge for a M1 vertical terminal with a M2 vertical segment.
The M2 is effectively bound to the M1 axis position.
* Bug: In Anabatic::NetBuilderVH::_do_xG_xM1_xM3(), in case of E/W global
and only one RoutingPad the connexion to the RoutingPad was duplicated.
It was valid, but totally stupid.
* Bug: In Anabatic::Session::_canonize(), for an aligned segment set,
intersect the user constraints from all segments instead of only
considering the canonical one.
Issue a warning about too tight constraints only for symbolic
gauges. It may be correct for the real ones.
* New: In Katata::DataNegociate::update(), more accurate computation
of the perpandicular free interval. Use segment extension cap
calculation. Create a special case for fixed axis segments allowing
them to find alternative free interval, try under source and under
target as they are likely to be draggable segments.
* Change: In Katana::Manipulator::relax(), use the extension cap value
to compute the axis of the perpandicular segemnts.
* Change: In Katana::Manipulator::moveUp(), now move up the whole set
of aligned segments instead of just the canonical one.
* Change: In Katana::NegociateWindow::loadRoutingPads(), more accurate
TrackMarkers insertions for fixed terminals.
* New: In Katana::RoutingEvent::Key::Compare::operator(), segments with
fixed axis are processed prior to any others.
* New: In Katana::RoutingEventLoop, store segment pointers instead of
ids to generate more accurate error messages.
* Change: In Katana::RoutingPlane::create(), perform local track
assignment only for HV gauges.
* Change: In Katana::SegmentFsm::_slackenLocal(), add a "dragMinimize"
step in the automaton. Mutliple states transitions can occurs in
a row if an action fails.
* New: In Katana::Session::_toIntervalAxis(), normalize interval
bounds so they are on track positions (by shrinking the interval).
* Bug: In Katana::TrackMarker CTOR, the weigh computation was wrong.
* Change: In Anabatic::GCell::doGrid(), remove the "3 slice height"
limit (for small digital analog blocs).
* Bug: In Anabatic::NetBuilder::setStartHook(), perform a check for
a RoutingPad still on a Plug. Diplay an error instead of crashing.
* Bug: In CRL::RoutingLayerGauge::getTrackIndex(), the upper bound
of the track interval must be included instead of excluded.
* New: In Hurricane::Cell, add a StayOnPlugs flags for flattenNets().
To keep the RoutingPad occurrences on Plug instead of selecting
physical components.
* New: In Isobar::PyNet, add setAutomatic() and isAutomatic() to the
interface.
* Bug: In Katana::protectRoutingPads(), do not create protections on
PinOnly layers (mostly metal1).
* Change: In Hurricane::Backtrace constructor, add a boolean parameter
to enable/disable the actual backtrace generation.
* Change: In Hurricane::Error constructor, disable by default the
backtrace generation. The backtrace is useful when the Error is
thrown, and the program therefore stopped. But in many case we
just issue the error message on the console and try to continue.
But if the backtrace is enabled, it terribly slow down the
program.
Have to think about an clean way to re-enable the trace only
when the exception is thrown.
* Change: In Hurricane::Technology, in all the layer connexity methods
(getLayers(), getMetalAbove(), getCutAbove(), getViaBetween(), ...)
the "useWorking" parameter is replaced by a more accurate "useSymbolic".
BEHAVIOR CHANGE: formerly, if a symbolic layer was requested, and
none was found, NULL was returned. Now, if the symbolic layer is not
found, we try to return the associated real one (same layer mask,
but not flagged as symbolic, and usually with a lowercase name).
All thoses changes have been propagated to Python bindings.
* Change: In Hurricane::BasicLayer and derived classes, rename the
"isWorking" attribute into "isSymbolic" (to match the technology
renaming).
* Change: In Hurricane::Cell::flattenNets(), ignore power, ground and
blockage nets for the flatten.
* Change: In CRL Core, in coriolisInit.py and Technology.py helpers,
rename the tables describing the technology as follow:
- symbolicLayersTable --> compositeLayersTable
- workingLayersTable --> symbolicLayersTable
- symbolicRulesTable --> layersExtensionsTable
This is to give the table names a more clearer semantic after
merging real technologies configurations (testbench AMS c35b4).
In particular, we need to define a composite layer for the
real VIAs, and not only the symbolic ones. And with correct
enclosures expressed in real dimensions (microns).
* Bug: In Hurricane the ::tstream class must be initialized with a
minLevel of 10000 instead of zero, as the minLevel go *towards*
zero as the debug slice [min:max[ is expanded by DebugSession.
This default value must be repeated in the CRL::System CTOR
and in the coriolis2/etc/commons/misc.conf.
* Bug: In Hurricane::IntrusiveSet, uses "tsetw(n)" dedicated cdebug
stream manipulator instead of the STL one.
* New: In Anabatic, rename GCellTopology to NetBuilder, expose the class
(no longer in a local namespace).
NetBuilder become a base class performing the walkthrough the Net
tree. Derived class are tasked to build routing for specific gauge.
NetBuilderHV is created to manage all gauge with metal2 horizontal
and metal3 vertical.
In our terminolgy we consider that the first routing metal is
metal2. Metal1 is used inside the standard cells.
* New: Hurricane::DataBase::getCell() method to search a cell through
all the libraries of *all* the frameworks, not just Alliance.
Also exported in Python interface.
* Bug: In Technology::getNthMetal() the function was not returning the
right metal, there was an offset of one. And when the offset was
0, no metal was even returned. Same fix goes for getNthCut().
The fault was in Mask<>::nthbit().
* Change: In Hurricane::CellWidget, the initial window size is too tiny.
Increase the size from 250 to 500 pixels.
* Bug: In Hurricane::Occurrence_Contains(), when the Instance to match
is set to NULL, that means we have to accept *all* instances instead
of rejecting them all. This bug was making the Cell::flattenedNets()
to do nothing in digital mode.
* New: Occurrence_Contains filter that tells if an instance is part of
an Occurrence. Checks for two cases:
- The Instance is part of the *path* of the Occurrence.
- The Instance is the associated entity itself.
* New: In Cell::flattenNets() adds a new parameter Instance* to
allow partial flatten of one instance only.
* Bug: In Anabatic::Disjstra::_materialize() check that the
NetRoutingState exists before trying to access it...
in Dijkstra.cpp/.h, Edge.cpp/.h, GCell.cpp/.h:
*Change: GlobalRouting wires can have different wires' width. One Net's wires has one width only.
in NetRoutingProperty.cpp/.h, PyNetRoutingProperty.cpp/.h:
*New: A wire width parameter is added. It can be set through python script.
* New: In Katana::TrackCost, the TrackElement and it's optional
symmetric are now kept as attribute of a TrackCost. The cost
is completly computed inside the constructor.
TrackCost now support any mix of symmetric event and wide
segments.
The cost is now computed by adding directly to the current
one instead of creating secondaries that are merged afterwards.
As a consequence, remove all copy construction and merge
capabilities.
All the various methods used to compute the cost are renamed
"addOverlapcost()" in all the various related objects.
As a reminder, the overal cost method call is as follow:
1. TrackCost constructor on a TrackElement.
2. Call TrackElement::addOverlapcost()
3. For all Track under the TrackElement, call
Track::addOverlapCost()
4. For all other TrackElement intersecting with
the overlap interval call:
TrackElement::incOverlapCost()
5. The callback overlap function for segments
is called (defined in NegociateWidow).
Don't confuse:
- TrackElement::addOverlapCost(), which compute the cost of
inserting the segment inside a track (or a set of).
- TrackElement::incOverlapCost(), which compute the cost of
overlaping with this already inserted segment. It is the
other way around of the previous one.
* Change: In Katana::SegmentFsm, use a vector of pointer to TrackCost
instead of an object to avoid copy construction.
* Bug: In Hurricane::Interval, the ::getSize() method was returning a negative
length when the Interval was empty. Now return zero. This was causing
slight cost functions side effect when computing the overlap of a segment
with another one belonging to the same net (i.e. shareDelta)
* Bug: In Katana::AutoSegment::computeOptimal(), checks that the optimal
position for the axis is indeed inside the GCell interval.
* Bug: In Katana::DataSymmetric::getSymmetrical(Interval&), reverse the shrink
applied to GCells sides. Interval are of the type [min:max[ so after
symmetric transformation they become ]smax:smin]. Apply a correction so
that they are [smax:smin[ and could be merged with the paired interval
(the one without symmetry applied).
* Bug: In katana::TrackCost::consolidate(), the overlap (now) always positive,
and must be *substracted* to the "delta" (not *added*).
* Bug: In Katana::_computeNetOptimals(), now skip the already processeds
AutoSegments instead of re-processing them.
* New: In Katana::AutoSegment::computeOptimal(), improved computation of
the axis hint:
- For analog net, propagate through the simple doglegs to find
attractors.
- Restrict the allowed interval to the union of GCell sides and
segments constraints that are terminals.
- Consider a local as "long" if it's length exceed 20 the P-pitch.
(maybe make that a tool parameter).
* New: In Anabatic_AutoSegments collection, added a Flag to the constructors
to allow different behavior between digital and analog modes.
For "Aligneds" and "Perpandiculars" collections, now manage a new
Flag WithDoglegs to follow aligned globals through local doglegs
(for analog nets).
Adjust the log level of collections to 144 (formerly 145).
* New: In Anabatic::AutoSegment, new flag SegAnalog for segments that are
part of an analog net.
Note that with this flag, we reach the 32 bits limit...
* Change: In Anabatic::Constants, Flags are now declared as BaseFlags
objects and *not* uint64_t. This avoids overload resolution problems with
arithmetical overload of the operators.
The BaseFlags/Flags types are now completly "isolated" from the
uint64_t, it has the advantage of showing where unwanted previous implicit
conversions where occuring.
* Change: In Katana::Constants, Flags values are now of BaseFlags type instead
of uint64_t.
* Change: In Anabatic::Dijkstra, lots of log cleanup.
* Change: In Anabatic::GCell::getSide(), make the "shrink" parameter visible
to allow to substract the topmost and rightmost track for axis span
computation in AutoSegment::computeOptimal(). Used for analog mode.
* Change: In NetRoutingState, added a flag for analog mode. Use uint32_t
for the flags type.
* New: In Isobar, export the NetRoutingState and NetRoutingExtension objects.
* Change: In all top CMakeLists.txt, force the use of Python 2.7 as
we do not compile against 3.x flavors. Do not use the "EXACT"
flags as it will not recognize 2.7.x versions.
* Change: In Katana::RoutingEvent::Key::Compare(), preliminary
experiments shows that the best sorting order is:
- Lower layer first (i.e. M2 -> M3 -> M4 -> ... )
- Longer segments first.
The later seems to be counter-intuitive. Guess is that placing
the small ones first generate a more important fragmentation of
the big ones. They are placed too early and are difficult to move
afterwards.
Another feature to test is *not* inserting pushed left/right
segments if they are not *already* routed.
* Change: In PyKatanaEngine.runNegociate() now takes a flag argument,
provided through the new PyKatanaFlags exported object.
(doChip.py must be changed accordingly)
* New: In Katana::Configuration, added "katana.profileEventCosts" to
triggers the event's profiling.
* New: In Katana::NegociateWindow::_negociate(), save a profiling
trace of all the events and their priority, separated by metal,
for later analysis (see doChip.py in alliance-check-toolkit).
* New: In Katana::RoutingEvent::Key::Compare(), start implementing
new segment freedom degree functions.
* Change: In Hurricane::Net::_getString(), put a more complete
information about the Net instead of just only it's name.
* Bug: In Katana, reorder the various stages so that they are
executed in the exact same sequence as in "doChip.py" so now
routing in graphic mode and text mode gives exactly the same
results.
* Bug: In Katana::PyKatanaEngine, runGlobalRouter do not take any
argument.
* Change: In Hurrican::Component::_preDestroy(), the cascaded destruction
of slaves Components and subsequent ring merge and Rubber creation
was using set<> sorted on pointer values. This was making the order
of destruction of the slaves components non-deterministic. Now the
sets are sorted according to their id (see Entity).
* Change: In Hurricane::SharedProperty, the _ownerSet is now a vector<>
instead of a set<>. This will slow the search process, but hopefully
this is needed only during construction/destruction of a Property
so the slow down shouldn't be too much.
This has also an impact on Hurricane::Relation.
* New: In Katana::SegmentFsm, the object is now able to handle two events
at the same time. The master and it's symmetric. When there is no
symmetric, the corresponing data is just left blank. This makes a
bigger object, but as there is only one when running, it is not an
issue.
Candidates tracks are now an vector of array<2> (pairs), the
TrackCost::Compare() functor has to be wrapped through CompareCostArray.
The compined TrackCost of the two tracks is accumulated into the first
element.
Everything related to events gets duplicated: _event is now _event1
and _event2, and so on.
As there can be now two Manipulator actions done with SegmentFsm,
this class now completly hide the Manipulator level from the
RoutingEvent processing.
New function ::bindToTrack() to perform the track insertion.
* New: In Katana::TrackCost, add a new ::merge() function.
* New: In Katana::TrackElement and Katana::TrackSegment, add symmetric
management. Allows to know if a TrackElement has a symmetric and to
access it.
* New: In Katana::DataSymmetric, add new overload for ::getSymmetrical()
to handle DbU::Unit and intervals.
* Change: In Katana::RoutingEvent, remove all direct uses of Manipulator
objects. Now any change to the event associated segment must go through
call to Segment Fsm.
* Change: In Katana, adjust the debug level so internal informations are
put below level 156.
* New: In Hurricane::DbU, in ::getValueString(), special display when the
value is Min or Max (more helpful than a gigantic number).
* Change: In Hurricane::CellPrinter::pageDecorate(), the size of the
cartouche was computed for a DPI of 150. Now it is computed to
expand as the DPI increase (scale from the 150 DPI values).
* Bug: In Hurricane::CellWidget, when setting up a state of a CellWidget,
the selection was not copied. Now copy the SelectorCriterion (clone).
* New: In Hurricane::SelectorCriterion, add a clone() method.
* Change: In CRL Core, in etc/common/display.conf, for the Printer.Coriolis
style, lower the thresold of display for the substrate layers so they
are shown even in small zoom mode.
* Change: In Hurricane::BaseFlags, store flags in uint64_t instead of
unsigned int because we start to need more than 32 different flags
in some tools.
* New: In ::getString() & ::getRecord() templates, add support for
std::array<>.
* Change: In CRL::ToolEngine, add support for timer (time & memory
measurements) displaced from Katabatic. This way all ToolEngine
can use this feature. The _postCreate() method display the
memory just after ToolEngine allocation.
* Change: In Etesian::EtesianEngine, make use of the ToolEngine
builtin timer (remove the local one). Forgot to call the base
class _postCreate() and _preDestroy().
* Change: In Anabatic::AnabaticEngine, make use of the ToolEngine
builtin timer (remove the local one).
* New: In Anabatic, new AutoSegments_Connecteds() collection. This
Collection allows a deterministic walkthough *all* the AutoSegments
connected either to source or target of one AutoSegment.
* New: In Anabatic::AutoContactTerminal::isEndPoint() to check if an
AutoContactTerminal is the *only one* anchored on a RoutingPad,
thus being a true "end point" and not a kind of feed-through.
* New: In Katana::KatanaEngine, added support for symmetric nets.
Created new class DataSymmetric to store symmetric information
of a net (mainly the paired AutoSegments).
Added KatanaEngine::runSymmetricRouter(), for now only build
the DataSymmetric informations. More to come...
* Change: In Katana::GraphicKatanaEngine::_runTest(), now perform
symmetric information building the non-symmetric routing.
- GlobalRouting takes into account self symmetries and symmetries in pair of nets according to an axis. Self symmetries are symmetries considering one net symmetric to an axis. During the materialize step, they are routed symmetrically according to the axis. Symmetries in pair of nets follow the same principle but with 2 nets.
In LocalGlobalRouting.cpp:
- Minor bug fixed
- Verbose commented
in NetRoutingProperty.cpp/.h:
- Some flags methods methods added
* Change: In Hurricane::Timer, measuring memory usage through the increase
of sbrk() gives erroneous results. Under Linux, now read the
/proc/[pid]/statm which gives the real size of the virtual memory
of the process. There is also code for reading /proc/[pid]/mmap
but it gives only the resident size of the process (i.e. swapped
pages are *not* accounteds).
* Change: In Katabatic, Anabatic, Kite & Katana now reports the total
memory size of the program.
* New: In Hurricane::NetRoutingProperty, added various flags for
symmetric support, axis and slave net (if any).
Json support is not complete yet: have to remember how to
get the slave net when present.
* Bug: In CRL.python.coriolisInit(), when it's not set, the stratus1.mappingName
configuration variable is equal to "" and *not* "not_set".
* Bug: In Etesian::EtesianEngine::toColoquinte(), followup of the previous
bug, bad FIXED/PLACED test when the AB is set.
* Bug: In Hurricane::Net::setExternal(), do not perform an UpdateSession
inside this function, it leads to unbearibly slow operation in the
clock-tree plugin.
* Bug: In Kite, backport corrections done in Katana and also relevant
for Kite.
* New: In Cumulus.ChipPlugin.py add support for Python profiling with
cProfile. Disabled under normal operation, but will certainly come in
handy sometimes.
* Bug: In Hurricane::JsonWriter, add support for "long long". Needed on
32 bits architectures to write DbU that are now int64_t which
resolves to "long long".
* Bug: In Hurricane::DbU, replace long by DbU::Unit (aka int64_t) in all
remaining occurrences.
* Change: In Hurricane::DbU::getValueString(), rewrite using ostringstream.
* Change: In Hurricane, in PyHurricane.h, PyAny_AsLong<> template to
convert any kind of Python integer into DbU, making sure we always
use 64 bits integers (long long for 32 bits and long for 64 bits).
PyDbU_FromLong<> template to peform the reverse, DbU to Python
integer in 64 bits (either using PyLong_FromLong() or
PyLong_FromLongLong()).
* Bug: In Isobar, in PyArg_ParseTuple(), never use the "l" direct
converter when reading a DbU. Instead read a PyObject then convert
using PyAny_AsLong<>. This ensure to never do a truncature.
* Bug: In CRL::ToolBox::attachPlugOrPin(), simply returns when there is
no plugs/pins to connect instead of doing an assert().
* Change: In Hurricane, more informative trace information for Python
ProxyProperty managment.
* Bug: In Stratus, when merging nets with the "<=" operator some table
of lookup of Hurricane Net are not updated correctly. As I don't
understand well enough the Stratus code **is is not corrected**.
* Change: In bootstrap/FindBootstrap.cmake, new setup_qwt() macro to
link with the Qwt library build with Qt 5 *or* Qt 4 and not the
first found.
* Change: In Hurricane/DbU, uses <int64_t> instead of <long> to always be
sure that we use 64 bits integers for coordinates.
* Change: In Katana/KatanaEngine::_gutKatana() checks that the
RoutingPlanes have been allocateds before trying to delete them.
* New: In Anabatic::AutoSegment, introduce a the kind (associated to a
flag) "LongLocal". Analog GCells can be very wide, so at least some
carefuly choosen long local segments must be took into account as
attractors in the computation of the optimal axis.
* New: In Anabatic::AutoSegment::computeOptimal(), take LongLocal into
account as attractors.
* Change: In ::GCellTopology constructors compare the layers of the
RoutingPads using layer masks instead of Layer pointers. Allows to
find both "METALx" (symbolic) and "metalX" (real).
* Change: In ::GCellTopology::_doHChannel(), _doChannel(), _doStrut()
and _doDevice(), tag long locals as "LongLocal". This need to be
reviewed as it as bind done a bit too quickly.
* Change: In Anabatic::AutoSegment, due too a much bigger span of the
analogic GCells the _optimalMin & _optimalMax bitfields must use
16 bits instead of 8 (they where overflowed).
* New: In Katana, reorganisation of the initialization procedure to fit
both digital and analogic cases. Create an analogInit() method.
* Change: In Katana::RoutingEvent, the _tracksNb and _tracksFree bitfields
where too short for the Analog GCell size, now uses 16 bits instead of
6.
* Bug: In Katana::GraphicKatanEngine::drawGCell(), skip drawing of a
GCell if *both* width and height are under 150 pixels.
* New: In Katana::Session, add a new isOpen() method.
* Change: In PyHurricane.h, in HCATCH macro, show the backtrace when
catching a C++ exception. No need to use the "hex" stream manipulator
if we cast into (void*).
* New: In Hurricane::UpdateSession, added "reset()" static function to
close all the currently opened sessions.
* New: In Hurricane::ExceptionWidget::catchAllwrapper(), close all
pending UpdateSession if the user choose to resume.
* Change: In Hurricane::Go, instead of immediatly materializing a newly
created Go (inserting it in a QuadTree) delay it until the closing
of the UpdateSession. We call "invalidate()" in "_postCreate()"
instead of "materialize()". This way, the abutment box of Gos is
taken into account only when the session is closed. There was a
problem when the abutment box was changing after the object creation
misleading the algorithm of the QuadTree. This was occuring only
when an object was created, not modificated, because in the later case
the Session mechanism was used. Now, the Session mechanism is used
in all cases.
As a side effect, it will speed up the parser by making all QuadTree
insertions in one step.
* Change: In Hurricane::JsonCell, forgot to call Cell::materialize() when
the Cell is completed (as was done in ordinary parsers). The call is
made in the destructor of the JsonCell.
* Change: In Hurricane::Cell, add QuadTree in the inspector support.
* Bug: In Hurricane, in StaticObservable::getObserver(), if the slot
pointer is NULL, do not try to access the owner. Returns NULL, so
the caller can be aware of the situation...
* Change: In Hurricane, in BreakpointWidget & ExceptionWidget some
cosmetic changes (fonts and window sizes).
* Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account
the constraints from the source AutoContact, as it holds the constraints
transmitted by the RoutingPads and sets up by propageConstraintsFromRp().
It is likely to be a bug affecting the original Katabatic as well.
* Change: In Anabatic, in RawGCellsUnder(), check that the segment is not
completly oustside the cell abutment box and truncate the coordinates
to the part that is inside. Use the "shrink" if we reach the east/north
border.
* Change: In Anabatic, in Configuration, no more decorator because we will
use a true derived relationship. Katana *derives* from *Anabatic* and do
not *decorate* it, so the Configuration can do the same. It also implies
that we directly create a Katana engine, not an Anabatic one.
* Change: In Anabatic, in Session, do not allow the opening of the Session
in a standalone fashion (with a static method). Instead it must be opened
using the relevant method of the Anabatic/Katana engine. This ensure we
are opening the right Session type.
* Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment
is not part of the collection by default, but will be included if the
Flags::WithSelf is set.
* Change: In Configuration, all the flags value are now defined in two steps.
Declared in the header and initialized in the module. This is to prevent
the fact that on some cases, in relation with the Python "extern C" part
modules, we need a true allocated variable. It was causing weird linking
problems.
A side effect is that they can no longer be used as entry is switches,
have to replace them by if/else.
* New: In Anabatic, new GCell::getNeighborAt() utility function.
* Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with
the grid type... Back annote all the edges capacity (north & east) with
the reserved local capacity.
* New: Complete portage of Kite over Anabatic. The new engine is christened
"Katana" for Kite-Analogic. When it's capabilities and performances
will be on a part with Kite, it is to completly replace it (and take
back the "Kite" name). Preliminary tests seems to show that, contrary
to intuition (because built on a more complex/slower grid), it is even
slightly faster than Kite 8-).
* Bug: In Hurricane, in NetlistWidget CTOR, the horizontal header was set
up assuing that there was (at least) three sections (column) in the
model, which was wrong. Now it is done in the setCell() method which
know the exact number of sections.
It was a bug in both Qt 4 & 5, but was showing only under Qt 5.
* Bug: In Hurricane, in Backtrace, under RHEL 6 when the package
<devtoolset-2-binutils-devel> is *not* installed, Backtrace uses the
wrong "bfd.h" from the system instead of the one from the devtoolset2,
causing itself to core.
The Backtrace, then try to create a second Backtrace from this
error, generating an infinite loop. To prevent this situation add a
counter so that only one Backtrace can be created at a any time.
And incidentally display a more meaningful error message along with
* New: In Bootstrap, add cmake detection for libbfd.
* New: In Hurricane, in Backtrace, add BFD support to read debuginfo from
the shared libraries (aka DSO) when compiled with "-g". This avoid the
tedious step of running gdb after generating a core dump. It is also
mandatory in ExceptioWidget to known from where an exception was thrown
as Qt::notify() block all C++ exceptions.
Currently works only under Linux (gcc or clang), may be extended in
the future.
The BFD reading is based on the small utility from:
Don Hatch (hatch@plunk.org)
http://www.plunk.org/~hatch/goodies/backtracefilt.C
And small trinket: adjust the size of the window for high DPI screens.
* New: In CRL Core & Unicorn add link toward libbfd, if needed.
* Bug: In Hurricane, in tstream (Commons.h), in the *template* overload of
operator<<(), do not use the operator<<() of ostream as it will be
looked up in "stage 1" (template definition) and so will miss all the
overloads added later and built over getString<>(). Instead, make use
of getString<>(), which, as another template will be looked up in
"stage 2" (template instanciation) and at that point will have all the
needed template specialisation of getString<>().
We also need to define new stream manipulators to be able to create
a matching template overload not dependant from the implementation.
To avoid name clashes, we prefix a 't'. For now, only 'tsetw()' is
refined.
As a side effect, we cannot directly print bit-fields into the stream,
we must go through an intermediate variable (happens once in AutoContact).
* 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::Observer, simplification of the template so that
we can use it directly instead of creating a derived class with an
implementation of Observer::notify(). Now the implemenation is the
same for all and just calls a notify() method on the owner object.
Create a StaticObservable for fast access of the observers. This
is mainly a fixed size table (array<>) with oberservers at known
indexes. This way we can go from the obervable to the observer
owner in one indirect access (or so I hope).
* Change: In Hurricane::CellViewer, use the new observers.
* Change: In Hurricane::ControllerWidget, use the new observers.
* Change: In Hurricane::CellWidget, set the winidow initial size to a
more sensible 500px.
* Change: In CRL::LibraryManager, use the new observers.
* Change: In CRL::LibraryManager, use the new observers.
* Change: In CRL, in display.conf & technology.conf, modification for
the ST hcmos9gp capacitors.
* Change: In Hurricane, in CellWidget, enable the drawing of ExtensionGos
according to the the threshold paramaters (as layers do).
* Change: In CRL Core, provide DrawingStyle for Anabatic::GCell &
Anabatic::Edge. Use the exact name of the ExtensionGo.
In kite.conf, add settings for the size of an edge as the optimal
size may change between analog & digital designs.
* New: In Anabatic:
- Support for fast position query using a matrix.
- Computation of the Edge capacity, based on the routing gauge parameters.
- Graphic display of the edges capacity. Added configuration
parameters to size the bounding box of an Edge.
* Bug: In Anabatic:
- GCell::_moveEdges was both too complex (some cases never arise the
way we divide GCells) and bugged.
* Bug: In Unicorn, in cgt.py, do not import Anabatic as it is not present
yet in the devel branch.
* Change: In Hurricane, in Commons.h, in the vector slot template, start
index at 0 and not 1 (to closer to the internal representation).
* Change: In ExtensionGo, forgotten trace system calls to update.
* Change: In Hurricane, in Flags add operator overload for "int" type
and not only "unsigned int". Otherwise the compiler complaints about
ambiguous overload when using enum values which are considered as
"int".
Simpler code for the BaseFlags::contains() method.
Added implicit conversion from BaseFlags toward bool type.
* Change: In Hurricane, in Commons, complete replacement of the previous
two trace systems (trace & ltrace) by a stream-based one.
As it is a true object it is much less fragile than the one based
on defines (but maybe a little slower).
Define a reservation table for the trace levels for all the
Coriolis & Chams components.
* Change: All tools, use the new trace system.
* Change: In Hurricane, in PyHurricane.h, in all DirectSet*() macros,
suppress the third parameter giving the function name. It is now
build from stringification of other parameters.
The various macros calls are also modificated all througout
Isobar.
Added PyAny_AsInt() to convert a Python Int or Long into an int.
Maybe we should manage only long, because the type difference seems
ambiguous in Python itself.
* Change: In Hurricane, in PyHurricane.h, in DirectGetBoolAttribute()
deduce the function name to display in messages from the arguments.
Idem for DirectIsAFromCStringAttribute(), DirectGetIntAttribute(),
DirectGetUIntAttribute(), DirectGetDoubleAttribute() and
DirectGetStringAttribute().
* New: In Hurricane, in PyHurricane.h, new macro DirectGetNameAttribute()
to build accessors for method returning a Name.
* New: In Hurricane, in PyHurricane.h, new macro DirectSetIntAttribute()
to build modificators taking int arguments.
* Bug: In Hurricane, in PyHurricane.h, in macro DirectSetBoolAttribute(),
the check for a boolean PyObject was wrong, leading the macro to
systematically emit a Python exception.
* Bug: In Hurricane, in PyInstance method table, PyLibrary_create() was
registered as a NOARGS function, but it *do* have arguments, change
to VARARGS.
* Bug: In Hurricane, in PyHurricane.h, the macro GENERIC_METHOD_HEAD was
not checking at all that the underlying Hurricane object was not NULL.
This may have lead to core-dumps.
* In CRL Core, in BlifParser, when an input terminal of an instance is
either connected to power or ground, insert a zero_x0 or one_x0
Cell to avoid direct connection to the supply (the router is not
able to do it). The names and terminals of the intermediate cells
are hard-wired for now (to SxLib).
When merging Nets, always merge internal nets into external ones
as the other way around is not always legal.
* In Hurricane, in Cell::flattenedNets(), if the cell has already been
flattened, do not issue warnings about duplictated flattened nets.
* In Hurricane, in Net, allow Net::setName() to switch the main name
for an alias without complaining about an already used name.
* In Cumulus, in RSavePlugin.py, when "views" is supplied in keywords
(kw) arguments, override the default instead of merging with it.
This is to allow scripts to save exactly what views they want.
* Change: In Hurricane, in DataBase::CellDepths() the recursion stop
criterion must be Cell::isLeaf() and not Cell::isTerminal() as
the second one can be used to hide some levels of hierarchy,
and we want all of them in a blob.
* New: In Hurricane, in Cell, create a new Slaveds relation to keep
track of all the Cells with a slaved abutment box. This work is
incomplete as we do not manage the behavior in case of merge or
Cell destruction or slaving Cells with aready slaveds ones.
Modify Cell::setAbutmentBox() to work in both autonomous and
slaved mode.
* New: In Hurricane, in Net, add a new type of Net: BLOCKAGE this
avoid us to be dependant on the framework pattern recognition.
(change propagated to the Python support)
* New: In CRL Core, in the various drivers, recognize blockage nets
as such and set their type accordingly.
* Change: In CRL, in Toolbox::deleteEmptyNets(), preserve blockage
Nets. This was the cause of crashs in Kite::BuildPowerRails() as
we where trying to use a deleted blockage net...
* Bug: In Hurricane, in NetAlias, do not write NetAlias as a name
but as a type. They were not read back and moreover staying in
the JSON parser stack.
* In Hurricane: In Instance::slaveAbutmentBox() and Instance::uniquify()
use isUnique() instead of isUniquified(). This way we do not clone
masterCells that are unique in the design. This was the reason
sometimes "holes" were appearing in the visualiser, as the AB were
not merged. The uniqification policy may need some refinement.
* Change: In Hurricane, in JsonReader::HurricaneHandler, add RawNumber().
Don't know what kind of data it parses, so for now if it's called,
just issue a warning.
* Bug: In documentation, in UsersGuide, add dependencies on doc_HTML and
doc_LaTeX so they are rebuild if the source files changes.
Some modifications to work with our new installation of TeXLive 2014.
* 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 Hurricane, in Cell_HyperNetRootNetOccurrences::Locator, must
also check that the current Net is not a DeepNet in the constructor.
Take the occasion to prune Net that are automatic.
* Change: In Hurricane, in DeepNet::_createRoutingPads(), check for
already created RoutingPads. That is, the DeepNet must not have
RoutingPad components or Segments components.
* Bug: In Hurricane, in Cell::flattenNets(), addition to the topHyperNets
vector was done *inside* the components loop, resulting in multiple
additions of the same top net. This was leading to the RoutingPads
created multiple times on the same connectors. Hence the conflict in
KiteEngine::protectRoutingPads().
* Change: In Hurricane, in Cell::flattenNets(), do not create RoutingPads
or build rings on already routed Nets. A Net is considered already
routed if it has at least one Segment. This way we avoid Rubbers to
be drawn over routed Nets.
* Change: In Hurricane, in DeepNet, do not build RoutingPads & rings on
already routed Nets (same condition as in Cell::flattenNets()).
* New: In Hurricane, in HyperNet, new collection of all component
occurrences of an HyperNet. May or may not (default) include
components from the leaf cells.
* Bug: In Hurricane, In Cell, the quad-tree cannot be mergeds because
when a geometrical search is performed, components, and even more
importantly, instances from lower hierarchical levels will be
reported. And there is no simple way to discriminate them.
* Change: In Hurricane, Cell & Instance, change the flag of
MergedQuadTree into SlavedAb.
* Bug: In Hurricane, In Instance::slaveAbutmentBox(), the AB of the
master model must be set before calling setPlacementStatus()
otherwise the Instance do not get inserted into the quad-tree
(empty AB).
* 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).
* 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.
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.
Details:
* New: in <bootstrap>: add support for devtoolset-2 in ccb. Run the
cmake commands through 'scl', set shell environment variables
BOOST_INCLUDEDIR & BOOST_LIBRARYDIR and disable the default
system path search.
* Change: In various flex scanners add the %nounput to suppress
compiler warnings.
* Change: Little cleanup for g++ 4.8.1 as it's more strict.
* Change: In various top CMakeLists.txt, suppress extraneous '/'
after DESTDIR.
Documentation restructuration:
* Bug: in <hurricane>: bad figure for transf-R1.
* Change, in <kite>: Remove deprecated configuration variables.
* New: documentation <tool> to regroup all documentation not directly
related to one tool.
* Change, in <crlcore>, move the user's guide and the top doc index
into <documentation>.
* New, in <documenation>: added Python script demo based on AM2901.
Project hierarchy reorganisation:
* With svn, we were doing a tool by tool checkout, suppressing the
whole repository hierarchy level.
* The tools were also grouped, inside one repository, into multiple
projects (<bootstrap>, <vlsisapd>, <coriolis>).
* We do not want to split up each tool into a separate repository,
given their tight integration (except for vlsisapd).
* We choose to simplify, and consider all tools in a svn repository
one project. Due to the way Git clone repositories, the directory
containing the project is now to be seen under "src/".
CMake modifications:
* Now that the <vlsisapd> and <bootstrap> projects are merged into
coriolis, modificate the top CMakeLists.txt of each tool to uses
only Coriolis (and bootstrap hard wired).
CCB compile script modifications:
* Uses the new source tree hierarchy, with the project directory
inserted.
* Remove (comment) all parts relateds to svn managment.
* Git is sufficiently simple so that we do not want to integrate
command shortcut into the script.
SVN cleanup:
* Remove the obsolete <chamsin> tool, that has become the full fledged
<chams> project long time ago.
- New: Added an id on DBo, SharedName and SharedPath to ensure
database determinism. All the hash key now uses the id instead
of the object's pointer (see _getHashValue()).
- Change: In RoutingPad, position is now only relative to the anchor,
no more (dx,dy). Add a isPlacedOccurrence() to check if all the
occurrence in the path are fixed and thus the position meaningful.
* ./hurricane/doc/hurricane:
- Change: In Cell, added doc about PlacementStatus.
- Change: In Transformation, more detailed explanations about the
orientations. A little beautifying too...
- Change: RoutingPad doc update.
- Change: Entity doc update (for id).
- Change: In HTML header/footer uses the new SoC.css.
