* New: In CRL/helpers/utils.py, create a Python "class decorator".
Works like a decorator but without the need of implementing
the Concrete/Abstract classes structure Design Pattern.
Create proxies in the derived class for the base class
attributes & methods.
* Change: In cumulus/plugins/alpha/block/configuration.py, enrich
the BlockState object to support core2chip parameters. Make it
even more autonomous from the Block class.
* New: In cumulus/plugins/alpha/core2chip, port of the core2chip plugin
and integration with the alphs/block plugin. At "constant features"
as a first. Only ported "cmos", phlib will be later.
Note: Keep the various hfnsX.py as toolboxes for future experiments.
* New: cumulus/plugins/block/hfns3.py, build the trunk of the
net as a RMST. First with the "Iterative One Steiner Point"
(terribly slow above 100 points) then with FLUTE.
For the global routing trunk, must be very cautious to
check that the cluster "graph point" is the one of the
it's buffer RoutingPad so both end up in the same GCell.
* New: cumulus/plugins/block/timing.py, stub for basic
timing computation and conversion between sink and
capacitance. Currently based on the fake 350nm given as
example in SxLib ("man sxlib"...).
* New: In Hurricane::NetRoutingProperty, add and change the meaning
of the following flags:
- ManualGlobalRoute : now means that a global routing *trunk*
is present, made of "gmetalh", "gmetalv" & "gcontact".
- Manualdetailroute : added, get the former meaning of
ManualGlobalRoute, that is, the detailed routing is
already present for this net, but can be changed by the
detailed router. Implies that it respect the Terminal,
HTee & VTee structuration.
* New: Add Anabatic::Diskstra::loadFixedGlobal(), to account
a manually global net into the edges capacities.
* New: In Anabatic::Edges::ripup(), exclude manually global routed
segments from the ripup. Change the segment sorting function
so that thoses segments are put in head of list (considered
as "smaller").
* Change: In AnabaticEngine::setupPreRouteds(), now detect manual
global routed and manual detail routed signals, and tag them
accordingly.
* New: In AnabaticEngine::Configuration & Session, add proxies
for the global routing layers ("gmetalh", "gmetalv", "gcontact").
* New: In Anabatic::Constants, add flags for global fixed and
detail routed nets.
* Change: In KatanaEngine::updateEstimateDensity(), now use int64_t
for flute coordinates.
* New: Add CRL::RoutingGauge::hasLayer(), to know if a layer is
managed by the gauge (comparison by mask).
* New: In CRL::PyAllianceFramework, export getCatalog(), in PyCatalog,
export the getState(name) method and add a PyCatalog_Link().
In PyCatalogState, add PyCatalogState_Link(), cannot use the
macro because of the C++ name resolution operator (Catalog::State).
* New: In Isobar, export the RoutingPads collection to the Python interface.
* New: In Hurricane::Net, export the getRoutingPads() method to the
Python interface (hence the need of the previous export).
* New: Added multiple clock support in H-Tree generation in alpha/block.
* New: In CRL/etc/<NODE>/<TECH>/plugins.py, added three new parameters
for block plugin config:
"block.spareSide" : The size of the minimum side of a buffered area.
(quad-tree leaf).
"spare.buffer" : The model of the cell buffer to be used.
"spare.maxSinks" : max number of sinks on a buffer before issuing
a warning (non-blocking).
* Bug: In Etesian::BloatCell::getAb(), never apply the bloat profile to
fixed cells. In case of buffers from the spare maxtrix it was leading
Coloquinte to detect an overlap of fixed cells, which it do not
support (rightly so).
* Change: In CRL/helpers.Trace, flush stderr before issuing the trace
message to avoid mixing up stdout & stderr (sometimes misleading).
* Change: In CRL/helpers.overlay.CfgCache, no longer display all the
applied setting after a call to apply(). Too verbose.
* Change: In CRL::Environment, regex_t are now pointers instead of values,
this way the "in initialization" flag can be removed (maybe still too
complicated).
* New: In CRL/helpers.overlay.CfgCache, add support for context manager,
so we can progressively remove the use of Configuration. One class
to use in all contexts (immedaite setting or storing a set of
Cfg parameters).
* New: In CRL/helpers/overlay.py, CfgCache class to hold a set of
configuration parameters and apply it on demand. It has a
different behavior than Configuration.
* Bug: In Hurricane/Commons.h, modify the getRecord<>() templates so
that for both vector<Element> and vector<Element*>, the individual
record created for each element are donne with pointers. That is,
for the vector<Element> case, we take a pointer.
As a general policy, except for the POD types, always use pointers
or references to data in the records/inspector. Never uses values
that can call the copy constructor.
Suppress INSPECTOR_PV_SUPPORT() macro, keep only
INSPECTOR_PR_SUPPORT().
Provide value support only for getString<>() template.
This value & copy constructor problem was causing a crash when
trying to inspect Hurricane::AnalogCellExtension.
* New: In Hurricane::Technology, change the API of the PhysicalRule,
now we can only create/get PhysicalRule, but setting the value of
the rule itself must be done on the rule.
Enhance PhysicalRule to provide for stepped rules, non isotropic
and ratio rules.
Merge TwoLayersPhysicalrule in PhysicalRule, much simpler to
suppress the management of derived classes. That means that we
loose a little memory as some fields are mutually exclusive.
Not a problem considering that there will not be so many of thoses
objects.
* New: In CRL/helpers.analogtechno.py, enhanced DTR support for rules
like:
('minSpacing' , 'metal1', ((0.4,20.0), (0.8,1000.0)), Length, 'REF.1')
('minEnclosure', 'metal1', 'cut1', (0.2,0.3) , Length, 'REF.2')
('minDensity' , 'metal1', 0.30 , Unit , 'REF.3')
The DTR parser has been updated, but not the oroshi.dtr Rule
cache for analog components. Given a rule name, the value used
will be the horizontal one of the first step.
* Change: In hurricane/doc/hurricane, re-generate the documentation
with updated support for Technology & PhysicalRule.
* Change: In CRL/helpers/__init__.py, to ensure a complete restart of
the database the __init__.py must be called again, but it's not the
case with reload() (see Python doc). So helpers.resetCoriolis()
must explicitly removes the Coriolis related Python modules from
sys.modules (calling "del sys.modules[moduleName]").
That list of Coriolis Python modules is built by calling
helpers.tagConfModules(), it will tag all modules added to
sys.modules since startup. It will remove (much) more than
Coriolis modules, but that should be ok.
* Change: In CRL/etc/{node*,symbolic}/TECH/__init__.py, add a call to
helpers.tagConfModules() for the techno modules to be erased on
reset.
* Bug: In CRL/Vhdl::VectorPortMap::toVhdlPortMap(), two problems:
1. Bad condition for the use of VstUseConcat. Must be used *only*
when there is more than *one* mapped name.
2. Missing case, when there is exactly *one* mapped name, that
means that we have one full width vector to vector assignement.
There may be another weakness here, for the portmap we assumes
that both vector are mapped in the *same* direction (which is
"downto" by our convention).
3. In the "bit by bit mapping case" (every bits of the vector are
differents bits), use the "signal + bit index" name instead of
juste the signal name (i.e. full width).
Solves the Libre-SOC/soclayout/experiment6/fpmul64 problem, now
we can avoid the YOSYS_FLATTEN.
* Change: In Vhdl:::Signal::toVhdlPort(), in Alliance VST signal with
undefined directions are typed "linkage". This may not be compatible
with vasy, so allow to replace them by "in".
* New: In CRL::Catalog::State, add a new flag VstNoLinkage to tell if
the VST driver should not use the "linkage" type.
* Change: In Vhdl::Entity, add a VstNoLinkage flag to disable the use
of the "linkage" type.
* New: In vlsisapd/PyConfiguration, add asDouble() to the Parameter
Python wrapper.
* New: In CRLCore/helpers/overlay, add support for float parameters
in configuratuon.
* Bug: In CRL::VectorPortmap::toVhdlPortMap(), unconnected bits where
correctly checkeds for multi-bits vectors (both ordered and holed),
but not for mono-bits connections (ONE bit of a vector).
* New: In CRL::NamingScheme, add a flag VstNoLowerCase, and its
management it in the Verilog to VHDL converter.
* Change: In CRL::BlifParser::Model::toVhdlModels(), disable the
lowercasing of identifiers. We shouldn't apply Alliance VHDL
subset constraits when reading blif files. So we will see
uppercase identifiers in Coriolis.
* Change: In CRL::VstParser, no longer lowercase identifiers that
are *not* VHDL keywords. Uppercases are legals in VHDL...
* New: In CRL::Catalog::State, add a new flag VstNoLowerCase to
tell if the VST driver should keep the uppercases.
* Change: In CRL::VhdlEntity, add a VstNolowerCase flag to disable
the lowercasing.
* Change: In CRL::vstDriver, lower case the file name if needed.
remove the previously opened filename if it differs from the
lowercased one.
* Change: In UnicornGui CTOR, disable VHDL enforcement for the
Blif parser.
* Change: In CRL::BlifParser, formerly, a zero/one cell was added for
each vss/vdd direct connection, generating a huge flock of cells.
Now only generate one per netlist.
It can be discussed whether to old behavior is more desirable,
it is a compromise between wire and area.
* Change: In CRL::AllianceFramework::getCell(), if the Cell is marked
as TerminalNetlist, then it may be a standard cell. So it's layout
must be loaded. So now, systematically try to load the layout of
netlist terminal cells.
* Change: In CRL::LefParser::_macroCbk(), create a Catalog entry for the
newly read MACRO (that is Cell) and sets the Logical, Physical,
InMemory and TerminalNetlist flags.
* Bug: In CRL::LefParser::_siteCbk(), check for NULL cell gauge.
* New: In CRL::AllianceFramework, add setCellGauge(), to set the default
cell gauge. Exported to Python.
* Change: In CRL/etc/common/technology.py, create variables for VIA
layers, so we can modify their properties afterwards.
* New: In CRL/etc/node45/freepdk45, port the configuration files to the
new Python "importable" format.
Note: in kite.py, all the gauges (Routing & Cells) must be named
"LEF.CoreSite" to please my LEF parser, so it can match the gauge
name with the SITE name for standard cells.
* Bug: In Anabatic::NetBuilderVH::_do_2G(), forgotten to be reimplemented
from the base class. Simply redirect to _do_xG().
* Change: In Katana::PowerRailsPlanes::PowerRailsplanes(), create plane
from the layers in the RoutingGauge and their associated blockages
instead of sweeping through all the basic layers.
Allow to distinguish bewteen "METAL" (symbolic) and "metal" (real).
* Bug: In CRL::ApParser::_parseInstance(), the instance coordinates where
stored in *static* variables (boo). Making the parser *not* reentrant.
But in _parseInstance(), it can be recursively called through
getCell() when an sub-instance layout was missing.
Also make non-static all other variables in the various parser
function.
* Bug: In CRL::VstParserGrammar & VstParserScanner, when loading the
instances models, we where loading both logical & physical views.
This was causing cases of reentrency of the parser, with reset
of the lexer static dictionary, leading to memory corruption.
Now the identifiers are stored in the YaccState of each
parsed cell and we only recursively call for the logical view.
* Change: In CRL::ApParser::_parseInstance(), recursively load the
physical views as they are no longer loaded by the Vst parser.
* Change: In CRL::AllianceFramework::getCell(), sets the
TerminalNetlist flag from the state (mode 'C' in CATAL) onto
the cell.
* Change: In EtesianEngine::loadLeafcelllayouts(), new functions to
load the layouts of the leaf cells if only the netlist has been
loaded.
* Bug: In CRL::ApDriver::DumpSegments(), reset the direction field to
NULL between iterations so it is recomputed for each component and
not keeping the first one ever guessed.
* Change: In CRL/helpers, cumulus/plugins, oroshi & karakaze,
Move towards more Python PEP8 compliance:
* All indentations sets to 4 spaces (in progress).
* In plugins, remove messages about software collections
and RHEL (too many case could wrongly lead to that).
Instead systematically uses "helpers.io.catch()".
* Put in lowercases all modules names. Note that C++ exported
modules *keep* their Capitalized names (to preserve the
identity with the C++ namespace).
* When making import, use full path.
* Rename the run function from "ScriptMain()" to "scriptMain()".
* Cleanup: In CRL/etc, remove obsoleted configuration files,
the one ending in ".conf". Keep those who have not been ported
to the new style yet.
* New: In Hurricane/src/configuration, first trial at replacing the
C preprocessor macros by C++ templates. Applied first to configuration
from VLSISAPD.
This is unfinished business, just a limited demonstrator for now.
It is installed as a separate Python library "Cfg2" which do not
interact with the rest of Coriiolis.
The end goal is to fully remove boost and merge VLSISAPD useful
components directly inside Hurricane.
* New: In Isobar::PyResistor, manage type RPOLYH and RPOLY2PH.
* Change: In Hurricane::Resistor, rename plate nets from "PIN1" and
"PIN2" into "t1" and "t2" (try to respect uniform naming scheme).
* New: In Karakaze/AnalogDesign.py, support for reading Resistor
parameters.
* New: In Orosshi, ResistorSnake.py imported from Mariam Tlili's work
and associated Resistor.py to make parameter conversion.
Currently we only uses vertical layout for resistors.
Added METAL2 horizontal terminals for resistors.
* Bug: In CRL::ApDriver::DumpSegments(), when saving RoutingPads build
on Pin *not* at the top level (that is, Pin from an instance),
use the pin's orientation to choose the segment type.
* NORTH/SOUTH becomes a Vertical.
* EAST/WEST becomes an Horizontal.
Formerly, the segment direction was guessed only for the bounding
box, leading to segments in incorrect directions leading to DRC
errors (in nmigen/ALU16, net "b(10)").
* Bug: In CRL/symbolic/cmos/technology.py, forgotten import for
WarningMessage.
* Change: In all tools, FindTOOL.cmake, no longer use LIB_SUFFIX to
search for tool libraries but try "lib64/" then "lib/".
* Change: In bootstrap/socInstaller.py, take Debian 10 into account.
* Change: In bootstrap/docker, move from Debian 9 to Debian 10.
In the Cell/Instance hierarchy, the "terminal" and "leaf cell" concepts
where not clearly defined and partially overlapping. Now, "Terminal" is
the refer to the physical hierarchy (layout) and "TerminalNetlist" to
the logical hierarchy (netlist). The logical hierarchy can be less deep
than the physical one thanks to a Cell dedicated cell flags. Collections
related to the physical hierarchy keep their old names, the one related
to the logical hierarchy are renamed from "Leaf" to "TerminalNetlist".
The name "Leaf" was too ambiguous (leaf for *what* hierarchy).
* Change: In Hurricane::Device, set the "TerminalNetlist" flag once and
for all. No need set it in all the derived classes again.
* New: In Hurricane::MultiCapacitor, added new parameter "dummy" to
create dummies around the capacity matrix.
* Change: In Hurricane::Cell, remove "Leaf" related methods, replace
them by "TerminalNetlist" one, especially Collections. Now we have
two clear sets of Collections to walkthough the layout or the
netlist.
Change the "Terminal" flag into "TerminalNetlist".
* Change: In Hurricane::CellCollections, rename "Leaf" into
"TerminalNetlist" collections and apply the new semantic to the
locators.
* Change: In Hurricane::DataBase, Leaf to TerminalInstance renaming.
* Change: In Hurricane::DeepNet, Leaf to TerminalInstance renaming.
* Change: In Hurricane::HyperNet, Leaf to TerminalInstance renaming.
* Change: In Hurricane::Instance, Leaf to TerminalInstance renaming.
* Change: In Hurricane::Viewer::HierarchyInformations, Leaf to
TerminalInstance renaming.
* Change: In CRL::AllianceFramework, Leaf to TerminalInstance renaming.
* Change: In CRL::Catalog, Leaf to TerminalInstance renaming.
* Change: In CRL::ApParser, Leaf to TerminalInstance renaming.
* Change: In EtesianEngine::AddFeeds, Leaf to TerminalInstance renaming.
* Bug: In EtesianEngine::resetPlacement, move there the loop over
non terminal netlist instances to flag fully placed sub-blocks
as terminal for the netlist. Only then remove the feed cells
from unplaced instances. Previously, the feed cells where stripped
even from already placed instances.
* Change: In Katana, Leaf to TerminalInstance renaming.
* Bug: In Bora::PyDSlicingNode, allow the range parameter to be the
Python None object when we do not want to pass one but need to
have it as positional parameter.
* Change: In Cumulus/clocktree/ClockTree.py, Leaf to TerminalInstance
renaming.
* New: In CRL/etc/node600/phenitec, ported configuration of Phenitec 0.6um
Compliant with DataBase reset.
* New: In CRL/python/helpers, added function "unloadUserSettings()" to
unload Python modules prior to a full reset.
Added "resetCoriolis()" to perform full DataBase reset.
* Change: In CRL::AllianceFramework, make it a derived class of DBo so
the destroy() is now provided.
* Bug: In CRL::AllianceFramework::getCell(), do not attempt any load if
the library list is empty. Should never occur except in case of a
botched databse reset.
* New: In CRL::AllianceFramework, new method "saveCATAL()" to write back
the catalog of a library and "saveCells()" to write back the cells.
Note: only cells actually loaded in memory will be write back.
* New: In CRL::Catalog, add method "saveToFile()" to write back the CATAL
of a library.
* Change: In CRL::ParserDriver, replace "const string&" by "string"
(improved string support of the GNU STL).
* Change: In CRL::ParserSlot, use string instead of Name.
* Change: In CRL::ApParser, make _layerInformation an ordinary attribute
instead of a static one. This allow for it's correct resetting
across databas resets.
* Change: In CRL::VstParserGrammar, reinitialize Vst::framework at each
parser call. Needed to support database reset.
* New: In Hurricane::DBo, add an object counter to be sure that when
we perform a reset, no remaining DBo is allocated. This is different
of the object id which is ever increasing.
Note that, at reset, we check against "1" remaining element as at
this point only Database is still allocated.
Add a new "resetId()" method. MUST NEVER BE CALLED except by
DataBase::_preDestroy().
* New: In Hurricane::Database, new clear() method to remove the Cells
of all the libraries in reverse hierarchical depth order.
Make use of the new CellsSort class.
* Change: In Hurricane::DataBase::_preDestroy(), call "clear()" and
DBo::resetId().
* Change: In Hurricane::Breakpoint, change the default callback to be
a static function. So we can restore it later.
* Bug: In Hurricane::Instance::_preDestroy(), there was yet another
loop of deletion over a collection for the shared pathes.
Replace it by the repetitive deletion of the first element.
* Bug: In Hurricane::Net::_preDestroy(), RoutingPads must be destroyed
prior to any other component.
* New: In Hurricane::ColorScale, add a "qtFree()" method for freeing
the Qt Brush, Pen & Color.
* New: In Hurricane::DrawingStyle, add a "qtFree()" method for freeing
the Qt Brush, Pen & Color.
* New: In Hurricane::Graphics, add a "disable()" method to call the
various "qtFree()" of the sub-objects.
* Bug: In CRL/BlifParser::Model::mergeAlias(), when a signal is aliased
toward $true or $false in a Blif file (through a ".name" statement),
it was directly merged to "vdd" (resp. "vss"), and if it is an
external signal, this leads to its removal, potentially making "hole"
in its interface.
Now, create a gate zero or one for each tied up/low signal. This
way the interface is fully kept. At the cost of some supplemental
gates.
* Change: In documentation, now generate the overall documentation using
Pelican instead of Sphinx. This allows to have an unified approach
between the coriolis.lip6.fr website and the local documentation.
So we keep using "only" two doc generators: doxygen & Pelican.
* Change: In bootstrap/FindBoostrap.cmake, remove the -fsanitize=address
as it requires the "san" librarie which may be difficult to install.
* Change: In CRL/symbolic/cmos45/kite.py, decrease the METAL3 pitch from
10l to 8l. This is for testing with 4 routing metal only technology
like AMS c35b4 symbolic.
* Change: In Katana/BloatProfile, add static bloat option, that is, only
cell bloated in the first pass will be bloated again in subsequent
ones.
Add a "katana.bloatOverloadAdd" parameter to more easily control the
amount added to the computed overload.
* Change: In Oroshi, start integration of multi capacitors as generator.
Translate generator parameter into CapacitorStack ones. Add code for
routing unit capacitor.
* Change: In Hurricane::Viewer::ExceptionWidget & CRL/python/helpers/io.py,
downscale icons for non-HiDPI screen.
* Change: In CRL/etc/common/display.py, change the display threshold of
METAL1 layer so it do not appear at high scaling.
* New: In Etesian, activate the "setFixedAbHeight()" feature and export it
to Python. Allows to increase the space margin at constant height.
To be used by the P&R conductor.
* Change: In Unicorn/cgt.py, when running a script, insert the current
working directory at head of the sys.path, not at the end. So installed
modules do not shadow local one.
* New: In Anabatic::Edge, new accessor "getRawcapacity()" to know the full
capacity of the edge, that is, the real maximum number of tracks that
can go through the associated side.
* Change: In Katana/BloatProfile/Slice::tagsOverloaded(), bloating policy
change, now bloat all the instances under the GCell, not only the first
one.
* Change: In KatanaEngine::runGlobalRouter(), restore the search halo growth
policy to expanding of 3 GCells every 3 iterations.
New metrics displayed, the edge wire length length overload.
* Change: In cumulus/plugins/ConductorPlugin.py, now accepts the following
configuration parameters:
- "anabatic.globalIterationsEstimate", maximum number of global
iterations during the bloating computation passes.
- "conductor.useFixedAbHeight", tells wether the additionnal blank
space must be added so the aspect ratio is kept or the height is
kept (and the block become wider).
Disable the display of "rubber" to unclutter a little the view.
This commit contains two set of features that should have been commited
separately.
1. Compliance with clang 5.0.1, tested with the RedHat collection
llvm-toolset-7. This allow Coriolis to be compiled under Darwin (MacOS)
with Xcode & macports. The bootstrap install system has been modificated
accordingly.
2. The basic support for routing density driven placement. Related
features are:
* Bloat property. Each Occurrence of an Instance can be individually
bloated. This property not attached to any tool to allow the placer and
router to share it as wanted. Nevertheless, it is defined in Etesian.
* BloatProfile in Katana, add individual Bloat properties to Instances
occurrences based on the East & North overflowed edges of each GCell.
* Support in ToolEngine for a "pass number" of a tool. This pass number
is mainly used to make "per pass" measurements. The MeasureSet system
is improved accordingly to support multiple values of a same measure.
* Embryo of "P&R Conductor" to perform the place & route loop until the
design is successfully placed. May be the first brick of a Silicon
Compiler.
* Change: In boostrap/FindBoostrap.cmake, in setup_boost(), added tag to
the python component for macport (ex: python27).
* Change: In boostrap/build.conf, put etesian before anabatic for
instance occurrence BloatProperty dependency.
Added option support for the "llvm-toolset-7" collection to build
against clang 5.0.1.
* Bug: In Hurricane::getRecord( const pair<T,U>& ), the getSlot<> templates
for first & second arguments must be called with <const T> and <const U>
as the pair itself is const (and not simply <T> & <U>).
* Change: In Hurricane::getSlot() temlate, only use "string" arguments and
not const string&, simpler for template argument deduction.
* Bug: In Hurricane::AnalogCellExtension, the StandardPrivateProperty<>
template has a static member "_name". Clang did show that the template
for this static number has to be put inside the namespace where the
template *is defined* (i.e. Hurricane) instead of the namespace where
it is instanciated (i.e. Analog).
* Bug: In Isobar, Matrix_FromListOfList(), PyInt_AsPlacementStatus() must
be put outside the C linkage back in the Isobar C++ namespace (clang).
* Bug: In Hurricane::DBo::~DBo, and derived add a throw() specification
(clang).
* Bug: In Hurricane::RegularLayer::getEnclosure() & setEnclosure(), change
signature so it matches the one of the base class (clang).
* Bug: In Hurricane::CellPrinter, use double brackets for initializer list
(clang).
* Change: In Hurricane::Breakpoint, reverse the meaning of the error level.
Only error level *lesser or equal* than the stop level will be enabled.
* Bug: In CRL/python/helpers/__init__.loadUserSettings(), must put the
current working directory in the sys.path as in certain configuration
it may not be included.
* Bug: In CRL::ApDriver, DumpSegments(), no longer generate segments when
encountering a RoutingPad on a top-level Pin Occurrence. The segment
was generated in the wrong direction, creating DRC violations on the
"mips_core_flat" example.
* Change: In CRL::Measures, partial re-design of the measurements management.
Now, each kind of measure can accept multiple values put in a vector.
The index is intented to match a tool run number.
* Change: In CRL::Histogram, add support for multiple sets of datas,
indexeds with tool run number.
* Change: In CRL::ToolEngine, add support for multiple pass number, add
addMeasure<> templates for the various data-types.
* Change: In CRL::gdsDriver & CRL::gdsParser(), comment out unused GDS record
name constants.
* New: Etesian::BloatProperty, property to attach to Instance occurrences
that contains the extra number of pitch to add to the cell width.
* Bug: In AutoSegment::CompareByDepthLength, the segment length comparison
was wrong, it was always returning true, which broke the "strick weak
ordering" of the comparison.
This was producing a core-dump in GCell::updateDensity() when sorting
a vector<>. The end() iterator was being dereferenced, leading to the
problem.
* Bug: In Katana::DataSymmetric::checkPairing(), the test for segments
whose axis is perpandicular to the symmetry axis was wrong
("!=" instead of "-").
* New: In Katana/GlobalRoute, new ::selectSegments(), selectOverloadedgcells()
and selectBloatedInstances() to automatically select segments from
overloaded edges, overloaded GCells and bloated cells.
* Change: In KatanaEngine, return a more detailed success state, distinguish
between global and detailed.
Add support for multiple routing iterations.
* New: In cumulus/python/plugins/ConductorPlugin.py, embryo of routing
driven placement.
* Bug: In CRL/python/helpers/__init__.py, in textPythonTrace(), when an
ErrorMessage was catched, the trace parameter was not correctly
extracted leading to an "exception in exception".
* New: In Isobar/PyCell, exported Cell::getNonLeafInstanceOccurrences()
collection.
* New: In Isobar/PyTransformation, type is now built so the tp_compare
is linked to the C++ operator==().
* Change: In Hurricane::SelectionModel, Hurricane::SelectionWidget and
CellWidget, no longer use Occurrences but directly the Selector property.
We also use the Selector to know if an Occurrence is selected by
looking at that property on it's Quark. This avoid a very lengthy
search in vector when there is many elements (say > 10000).
NOTE: This is a bad implementation as there is a confusion between
beeing selected (that is, having a Selector property attached to
an Occurrence Quark) and being actually displayed as selected.
This lead to awkward implatation of the various "toggle" methods.
Have to rethink that more clearly later.
* Bug: In CRL::Histogram, the non-inline template full specialisation
of Measure<Histogram> must not be put in the header but in the module
to avoid multiple definition and link failure. They are actually
real, classic functions.
* New: In CRL/python/helpers.io, vprint() wrapper around print to display
messages according to the verbose level.
In etc/*, add messages in every configuration files so we may know
under which we are running.
* Change: In Hurricane::Isobar/PyHurricane.h, make the hash function use
the DBo id whenever possible instead of the object pointer, fall back
to it for standalone objects (Box like one). The DirectHashMethod()
macro generate a C style function (linkage) which call a template
function "getPyHash<>()" that uses a SFINAE mechanism to select
the right variant.
Create two comparison macros DirectCmpByPtrMethod() and
DirectCmpByValueMethod() to customize the comparison for objects that
have C++ operator==(). So now two boxes with the same contents will
be seen equal by Python. For DBo objects we keep the previous
comparison by C++ pointer.
* Change: In CRL::RoutingLayerGauge::getHorizontalGauge(), when selecting
the default gauge, try, if possible to avoid the PinOnly one.
Same goes for the vertical one.
* Bug: In Katana::TrackCost CTOR, symmetric track axis position was wrong,
was using the reference instead of the symmetric.
* Bug: In BoraEngine::updatePlacement(), set up the Dijkstra search halo
to one pitch so it can use immediately neighboring channels.
* New: In BoraEngine, added python startup hook like in Katana. Mainly
to setup debug nets.
* New: In BasicLayer::Material, added "info" kind of material for layers
that are only informationals (i.e. not real GDS one). Created to
store geometric combination of layers, this is a temporary solution.
Have to define a clearer semantic for that.
* New: In CRL/helpers/AnalogTechno.py, new "Count" type for count numbers
that must not go through DbU::Unit converter. They are plain integers,
but stored in DbU::Unit (keeping track of that semantic is left to
the user).
* New: In Analog, added Analog::ResitorFamily & Analog::Resistor classes.
* New: In Analog, added inspector support for all Parameter classes.
* New: In Analog, new FloatParameter class (for resistor value).
* New: In CRL/etc/scn6m_deep_09/devices.py, added resistor device.
* New: In Oroshi, support for Resistors, stub for ResistorSnake generator.
* New: In Bora::DNodeSets, added support for Resistor devices.
* Change: In Bora::DSlicingNode, rename setNFing()/getNFing() into
setBoxSetIndex()/getBoxSetIndex() for semantic coherency.
* New: In Karakaze/python/AnalogDesign.py, added support for Resistor.
Change in addDevice(), the span which was only meaningful for
transistor devices is replaced by a parameter argument.
The parameter argument has to be consistent with the device type.
