* 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.
