* Bug: In CRL::GdsDriver::hasLayout(), a Cell was saved in the GDSII
stream only if it has a layout, but the check was not accurate
enough. In the Arlet6502, the whole core was missing.
Now check for the abscence of Plugs (not unfinished Nets) and
PLACED/FIXED instances.
* Bug: In CRL/GdsStream::toGdsDbu(), when converting a physical number,
in double to a number of GDSII dbu in int32_t, we must not use the
direct cast int32_t(v) because v can be 2.9999999999 which got
simply truncated into 2 while we want 3. So now use the rounding
function std::lrint() and configure it round to the *nearest*
integer.
Note that we don't check that the long returned can correctly
fit into int32_t.
* Change: In CRL::vstDriver(), remove all Vhdl properties after running.
The properties are not updated if the cell (Entity) change, so the
next time it is called, an incomplete or incoherent state was saved
(for example, incomplete "port map"). Removing all properties is
less efficient but works.
* Cleanup: In CRL/helpers/overlay, remove forgotten debug message.
* New: In CRL::AllianceFramework::wrapLibrary(), can now add in the set
of AllianceLibrary one which is wrapped around another one. All the
cells must be already present and do attempt to save them with
AllianceFramework (AP parser will drive nonsensical datas).
* 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).
* 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).
* 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.
* 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.
* 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.
* 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.
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.
* 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.
* In CRL::Cyclop/CMakeLists.txt, add *again* the MOC files to the list
of .cpp . Don't know what is happening here with MOC under Qt 5.
* In CRL/python/helpers.io, cleanly fails if neither PyQt 4 nor PyQt 5 is
found. And tell it directly because this the module tasked to handle
the exceptions/errors...
* In Cumulus/plugins/AboutWindow.py, try PyQt 4 then PyQt 5.
* In documentation/UsersGuide, now tells explicitely that Qt 4 must be
used under RedHat 7 and Qt 5 under Debian.
* New: In bootstrap/coriolisEnv.py, add the "etc" directory to the
PYTHONPATH as initialization are now Python modules.
* New: In Hurricane/analogic, first groundwork for the integration of
PIP/MIM/MOM multi-capacitors. Add C++ and Python interface for the
allocation matrix and the list of capacities values.
* Change: In Hurricane::RegularLayer, add a layer parameter to the
constructor so the association between the RegularLayer and it's
BasicLayer can readily be done.
* Change: In Hurricane::Layer, add a new getCut() accessor to get the
cut layer in ViaLayer.
* Change: In Hurricane::DataBase::get(), the Python wrapper should no
longer consider an error if the data-base has not been created yet.
Just return None.
* Bug: In Isobar::PyLayer::getEnclosure() wrapper, if the overall
enclosure is requested, pass the right parameter to the C++ function.
* Change: In AllianceFramework, make public _bindLibraries() and export
it to the Python interface.
* Change: In AllianceFramework::create(), do not longer call bindLibraries().
This now must be done explicitely and afterwards.
* Change: In AllianceFramework::createLibrary() and
Environement::addSYSTEM_LIBRARY(), minor bug corrections that I don't
recall.
* Change: In SearchPath::prepend(), set the selected index to zero and
return it.
* Change: In CRL::System CTOR, add "etc" to the PYTHONPATH as the
configuration files are now organized as Python modules.
* New: In PyCRL, export the CRL::System singleton, it's creation is no
longer triggered by the one of AllianceFramework.
* New: In CRL/etc/, convert most of the configuration files into the
Python module format. For now, keep the old ".conf", but that are no
longer used.
For the real technologies, we cannot keep the directory name as
"180" or "45" as it not allowed by Python syntax, so we create "node180"
or "node45" instead.
Most of the helpers and coriolisInit.py are no longer used now.
To be removed in future commits after being sure that everything
works...
* Bug: In AutoSegment::makeDogleg(AutoContact*), the layer of the contacts
where badly computed when one end of the original segment was attached
to a non-preferred direction segment (mostly on terminal contacts).
Now use the new AutoContact::updateLayer() method.
* Bug: In Dijkstra::load(), limit symetric search area only if the net
is a symmetric one !
* Change: In Katana/python/katanaInit.py, comply with the new initialisation
scheme.
* Change: In Unicorn/cgt.py, comply to the new inititalization scheme.
* Change: In cumulus various Python scripts remove the call to
helpers.staticInitialization() as they are not needed now (we run in
only *one* interpreter, so we correctly share all init).
In plugins/__init__.py, read the new NDA directory variable.
* Bug: In cumulus/plugins/Chip.doCoronafloorplan(), self.railsNb was not
correctly managed when there was no clock.
* Change: In cumulus/plugins/Configuration.coronaContactArray(), compute
the viaPitch from the technology instead of the hard-coded 4.0 lambdas.
In Configuration.loadConfiguration(), read the "ioring.py" from
the new user's settings module.
* Bug: In stratus.dpgen_ADSB2F, gives coordinates translated into DbU to
the XY functions.
In st_model.Save(), use the VstUseConcat flag to get correct VST files.
In st_net.hur_net(), when a net is POWER/GROUND or CLOCK also make it
global.
* Change: In Oroshi/python/WIP_Transistor.py, encapsulate the generator
inside a try/except block to get prettier error (and stop at the first).
* New: In CRL::ApDriver::DumpSegments(), drive as top-level segments the
RoutingPads using a Pin, and not only using a segment. They are not
exported as top level Pin but only as Segment as they do belong to
a deeper level.
* New: In Cumulus/plugins/PadsCorona.Side._placePads(), now manage both
"pxlib" and "phlib*". Pad library management is still hardcoded, this
should be made a configuration option someday.
* Bug: In CRL::cstDriver(), re-activate the management of the VstUseConcat
flag. Why was he removed in the first place?
* Change: In KatanaEngine::runGlobalRouter(), no longer give the details of
each overflowed edge and the complete list of impacted nets.
Only a count.
This commit degrades the run success rate of ARMv2a to 87% (40 iters).
* New: In CRLcore/etc/.../kite.conf, add configuration parameters:
katana.termSatReservedlocal
katana.termSatthreshold
for the new edge capacity computation system.
* New: In CRLcore/etc/symbolic/phenitec06/, add support for N. Shimizu
small I/O pads (supplied in phlib80). Tune various parameters of
Anabatic/Katana to increase routing success.
* Change: In CRLcore/alliance/ap/ApParser, make Pin external components,
so RoutingPad will be build upon in global routing.
Do not complain when a I/O pad has a physical instance that did
not exists in the netlist. Just create it (appeared in phlib80).
When no netlist instance exists in a pad, the pad Cell is still
considered as terminal.
* New: In Etesian::BloatCells, new profile named "3metals" better suited
for two routing metals technologies (i.e. Phenitec).
* New: In Anabatic::RawGCellsUnder, new CTOR which take only source &
target points instead of a segment. Needed to manage wide segment for
which the axis to consider is not that of the segment (one axis for
each track it intersect).
* New: In Anabatic::GCell, add a RoutingPad count attribute, for Edge
reservation computation.
* New: In AnabaticEngine::computeEdgeCapacities(), instead of decreasing
all edges of a fixed amount (hTrackReservedLocal), guess the GCell
cluttering from the number of RoutingPads that it contains.
For non-saturated GCells, the four edges are decreased by the number
of RoutingPads. We use the maximum from the two neigboring GCells.
The hTrackReservedLocal parameter is now used only as a *maximum*
that the edge reservation can reach.
If a GCell is saturated (more than 8 RoutingPads, the saturation is
propagated horizontally to 2 neigboring GCells).
* Change: In AutoContactTerminal::getNativeConstraintBox(), use a more
flexible gauge name matching for terminal vertical extensions correction.
Namely, match all "msxlib*" kind of gauges.
* Change: In AutoSegment::setAxis(), add the ability to force the axis
position, even if it is a non-canonical segment. Maybe needed in the
initialisation steo, before the first canonisation is performed.
* New: In NetBuilder, added new methods _do_1G_1PinM1() and _do_2G_1PinM1(),
to manage coronas for Phenitec designs.
To avoid various side effects from segments being too close from
the north / east side of the routing area, make those segments fixeds.
* Change: In KatanaEngine::annotateGlobalGraph(), the management of wide
wires was wrong. The axis to use to find the underlying GCells is the
one of the track, not of the segment. This was creating bad edge
capacity computation under the power ring of a block and subsequently
routing failures.
* New: In Kanata::Manipulator, added method reprocessParallels(), not used
though, but keep it anyway, might be of use later...
* New: In Kanata::Manipulator, added method avoidBlockage() for terminal
METAL2 in non-preferred direction, restrict the terminal and turn
constraint box at the current position of the perpandicular, so it
doesn't create a deadlock in METAL2.
* Change: In SegmentFsm::conflictSolveByPlaceds(), if we cannot break
using the whole overlap, try the first atomic overlap.
* New: In SegmentFsm::_slackenStrap(), manage conflict between a non-prefered
segment and a blockage, this when to call avoidBlockage()...
* New: In Katana::Configuration, management of the new edge computation
parameters:
katana.termSatReservedlocal
katana.termSatthreshold
* New: In Cumulus/plugins/Core2Chip, support for Phenitec I/O pads.
* Bug: In cumulus/plugins/PadsCorona.py, when a pad is at the beginning
or at the end of the side, the pad corona terminal may be outside
the corona range (not directly facing it). In that case, create a
bend to reach it.
Worse, in some case more than one (but likely no more), could be
in that case, so not only do we create a bend but also make a
shift in the bended segment so two consecutive ones are not on the
same axis, causing shorts.
If both end pads of a corner are in that case, we cannot prevent
a short, so at least, issue a warning.
* Bug: In CRL::Vhdl, the Entity::VstUseConcat was not passed correctly
along, so we did get a strange mix of conat and direct assignment.
* New: In Unicorn/cgt.py : added --vst-use-concat options to control
the VST driver behavior.
* Bug: In CRL::ApDriver & CRL::ApParser, when saving a fused net, do not
use it's name but put a star (*) character to set it anonymous.
Having all component named was creating problems in cougar and
subsquently in yagle (bad name for master latch).
Conversely, in the parser, if the name of the net is "fused_net",
make it a real fused_net and not an ordinary one.
* New: In CRL::AllianceFramework::saveCell(), through the view flag we
can pass an option 'CRL::Catalog::State::VstUseConcat' to tell the
driver tu use or not the concat '&' in PORT MAP statements.
It is not completely clean that the flag for controlling the VST
driver behavior is put in the Catalog states, but it's easier for
now...
And, of course, exported at Python level.
* In CRL::vstDriver(), remove the Vhdl::EntityExtension right after driving
the file. This avoid keeping in memory a mostly usnused structure and
solve the "second write after modification" problem.
* Change: In CRL/BlifParser::Model::mergeAlias(), do not always merge the
net2 with net1 (RHS with LHS of the ".name" instruction). This may
result in a name change in the design interface (external net).
Instead, merge any internal net with the external, so keep the
external net name. If both are external, keep the one with the lower
id (which should have been created first).
* Change: In Hurricane::SharedName, replace the incremental Id by a hash key.
This is to ensure better deterministic properties. Between use cases,
additional strings may have to be allocated, shitfing the ids. Even if
hash can be duplicated, we should be able to ensure that the absolute
order in map table should be preserved. Supplemental strings are inserted
in a way that keep the previous order.
* Change: In CRL/etc/symbolic/cmos/kite.conf, add "katabatic.routingGauge"
default parameter value ("sxlib").
* Change: In CRL/etc/common/technology.conf, define minimal spacing for
symbolic layers too (added for METAL4 only for now).
* Change: In CRL::Histogram, extend support to dynamically sized histograms.
Add a text pretty print with table and pseudo-curve.
* Change: In Cumulus/plugins/ClockTreePlugin, create blockage under the
block corona corners so the global router do not draw wire under them.
This was creating deadlock for the detailed router.
When the abutment has to be computed, directly use Etesian to do it
instead of duplicating the computation in the Python plugin.
* New: In Etesian, as Coloquinte seems reluctant to evenly spread the
standard cells, we trick it by making them bigger during the placement
stage. Furthermore, we do not not uniformely increase the size of the
cells but create a "bloating profile" based on cell size, cell name
or it's density of terminals. Currently only two profiles are defined,
"disabled" which does nothing and "nsxlib" targeted on 4 metal layer
technologies (aka AMS 350nm, c35b4).
* Bug: In Knik::MatrixVertex, load the default routing gauge using the
configuration parameter "katabatic.routingGauge" as the default one
may not be the first registered one.
* New: In AnabaticEngine::setupNetDatas(), build a dynamic historgram of
the nets terminal numbers.
* Bug: In Anabatic::AutoContact::Invalidate(), always invalidate the
contact cache when topology is invalidated. In case of multiple
invalidations, if the first did not invalidate the cache, later one
that may need it where not allowed to do so. The end result was correct
nonetheless, but it did generate annoying error messages.
* Bug: In Anabatic::AutoContactTurn::updateTopology(), bad computation
of the contact's depth when delta == 2.
* Bug: In Anabatic::Gcell::getCapacity(), was always returning the west
edge capacity, even for the westermost GCell, should be the east
edge in that case.
* New: In Anabatic::AutoSegment, introduce a new measure "distance to
terminal". This is the minimal number of segments separating the
current one from the nearest RoutingPad. This replace the previous
"strong terminal" and "weak terminal" flags.
This distance is used by Katana to sort the events, we route the
segments *from* the RoutingPads *outward*. The idea being that if we
cannot event connect to the RoutingPad, there is no points continuing
as thoses segments are the more constraineds. This gives an order close
to the simple ascending metals but with better results.
* New: In Anabatic::AutoSegment, introduce a new flag "Unbreakable", disable
dogleg making on those segments. mainly intended for local segments
directly connecteds to RoutingPads (distance == 0).
* New: In Anabatic::AutoSegment, more aggressive reducing of segments.
Now the only case where a segment cannot be reduced is when it is
one horizontal branch in a HTee or a vertical on a VTee. Check if,
when not accounted the source & target VIAs are still connex, if so,
allow reducing.
* New: In Anabatic::AutoContact, new state flags CntVDogleg & CntHDogleg
mainly to prevent making doglegs twice on a turn contact. This is to
limit over-fragmentation. If one dogleg doesn't solve the problem,
making a second one will make things worse only...
* Bug: In Anabatic::Configuration::selectRpcomponent(), we were choosing
the component with the *smallest* span instead of the *bigger* one.
* New: In Anabatic::GCell, introduce a new flag "GoStraight" to tell that
no turn go be made inside those GCells. Mainly used underneath a block
corona.
* New: In AnabaticEngine::layerAssign(), new GCellRps & RpsInRow to manage
GCells with too many terminals. Slacken at least one RoutingPad access
when there is more than 8 RoutingPad in the GCell (slacken or change
a vertical METAL2 (non-preferred) into a METAL3).
* Change: In Anabatic::NetBuilderHV, allow the use of terminal connection
in non-preferred direction. That is, vertical METAL2 directly connected
to the RoutingPad (then a horizontal METAL2). This alllows for short
dogleg without clutering the METAL3 layer (critical for AMS c35b4).
Done in NetBuilderHV::doRp_Access(), with a new UseNonPref flag.
Perform some other tweaking on METAL1 access topologies, to also
minimize METAL3 use.
* New: In AnabaticEngine::computeNetConstraints(), also compute the
distance to RoutingPad for segments. Set the Unbreakable flag, based
on the distance and segment length (local, short global or long global).
New local function "propagateDistanceFromRp()".
* Change: In AnabaticEngine.h, the sorting class for NetData, SparsityOrder,
is modificated so net with a degree superior to 10 are sorted first,
whatever their sparsity. This is to work in tandem with GlobalRouting.
* New: In Katana::TrackSegmentNonPref, introduce a class to manage segment
in non-preferred routing direction. Mostly intended for small METAL2
vertical directly connected to RoutingPad. Modifications to manage
this new variant all through Katana.
* Change: In Katana::GlobalRoute, DigitalDistance honor the GoStraight flag
of the GCell. Do not make bend inside thoses GCells.
* Change: In KatanaEngine::runGlobalRouter(), high degree nets (>= 10) are
routed first and whitout the global routing estimation. There should be
few of them so they wont create saturations and we want them as straight
as possible. Detour are for long be-points.
Set the saerch halo to one GCell in the initial routing stage (before
ripup).
* Bug: In KatanaEngine & NegociateWindow, call _computeCagedconstraints()
inside NegociateWindow::run(), as segments are inserted into tracks
only at that point so we cannot make the computation earlier.
* Change: In Katana::Manipulator::repackPerpandiculars(), add a flag to
select whether to replace the perpandiculars *after* or *before* the
current segment.
* Change: In Katana::NegociateWindow::NegociateOverlapCost(), when the
segment is fully enclosed inside a global, the longest overlap cost
is set to the shortest global hoverhang (before or after).
When the cost is for a global, set an infinite cost if the overlapping
segment has a RP distance less or equal to 1 (this is an access segment).
* Bug: In Katana::PowerRailsPlane::Rail::doLayout(), correct computation of
the segments extension cap.
* New: In Katana::QueryPowerRails::addToPowerRail(), add support for Pad.
* Change: In Katana/PreProcess::protectCagedTerminals(), apply the contraints
to any turn connected to the first segment of the RoutingPad so the
perpandicular constraints got propagated to the perpandicular segment...
* Change: In RoutingEvent, cache the "distance to RP" value.
* Change: In RoutingEvent::Key::compare(), sort *first* on distance to
RoutingPad, then layer depth. If both distance to RoutingPad is null,
then sort on segment length.
* Change: In RoutingEvent::_processRepair(), try a repack perpandicular with
perpandiculars first (then with perpandicular last, then give up).
* Change: In SegmentFsm::bindToTrack() and moveToTrack(), set an axis hint
when creating the insertion event.
* Change: In SegmentFsm::_slackenStrap(), add a step through slacken between
minimize and maximum slack (wihch directly end up in unimplemented).
* Change: In Session::_addInsertEvent(), add an axis parameter needed when
the axis of the segment is not the one of the track (case of wide
segments or non-preferred direction).
* Bug: In Track::_preDestroy(), bad management of the TrackElement reference
count. Destroy the segment only when reaching zero...
* Bug: In Track::expandFreeIneterval(), forgotten to manage case when there
is a set of overlaping segments at the "end" of the track, the
EndIsTrackMax was not set.
* Change: In TrackCost::Compare, increase the cost when an overlaping
segment is at it's ripup limit. We should try *not* to rip it up if
we can. Add a dedicated flag "AtRipupLimit".
* Change: In TrackElement, add proxies for isUnbreakable(), new function
updateTrackSpan().
* New: In TrackFixedSegment CTOR, when a supply wire of METAL2 or above is
found, make the underlying GCells "GoStraight".
* New: In TrackElement::canDogleg(GCell*), check for already done perpandicular
dogleg on source/target (reject if so).
* 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...
* Bug: In CRL/etc/symbolic/cmos/plugins.conf, rails dimensions are no
longer expressed directly in lambda. Must be created using helper.l().
* Change: In CRL::ApParser, slightly more smart management of Pin width.
Must normalize Pin behavior between Alliance & Hurricane as in
Alliance they have only one dimension.
* Change: In CRL::LefImport, if a net name end with "!", assume it's a
global one. Have to check this naming convention.
* Change: In Anabatic::NetBuilderHV::_do_1G_1PinM3() & _do_1G_1PinM2()
now implemented. Needed for the corona routing support.
* Change: In AnabaticEngine::setupPreRouted(), exclude segments outside
the abutment box.
* Change: In KatanaEngine::PowerRails, remove the I/O pad support as now
we route only inside the Corona. So only one vdd/vss/ck are supported.
* New: In cumulus/plugins/ChipPlugin.py, complete rewrite of the chip
support:
* Uncouple pad I/O ring whith real cells (foundry) from a symbolic
core. A new intermediate level "corona" is introduced to handle
the real/symbolic transition.
* Ability to explicitly setup position of the pads on the chip side
in case of uneven distribution.
* Enable clock tree to be build with 3 metal only (M2 to M4) instead
of (M2 to M5).
* 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.
* 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.
* Change: In CRL::DefImport, added callback to read the DEF UNITS statement
and perform a correct length conversion. Previously set to read pseudo
lambdas in hundredth of microns.
Added DefParser::getLefCell() to lookup master cells in the LEF
libraries before looking in the Alliance ones (rooted under "LEF"
library).
* Change: In CRL::LefParser::_pinPostProcess(), when no segment suitable
for terminal connexion is found, add all of them. This is a quick hack
and an a correct policy that match all techno must be implemeneted.
* New: In CRL::pyCRL, add a Python wrapper for DefImport.
* New: In CRL/etc/45/ispd18/ added configuration files for the "real"
technology used by the ISPD18 45nm design benchmarks.
* 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 CRL::cyclop, on former versions of Qt 5 there was a double
link of the moc generated modules. This appears to be solved under
Ubuntu 10.04 LTS, so now we have to add them again explicitly.
* Bug: In Katana::Track::expandFreeInterval(), the OutsideElement case was
not handled correctly, the end index must be increased in that case.
As a result, this function was returning too short an interval.
This was affecting the computation of perpandicular free interval
in DataNegociate::update() for perpandicular fixed but not in a track.
* New: In Anabatic::NetBuilder and NetBuilderVH, now manage GCells with
one Pin, and up to three globals. Used to put terminals at the
edge of a block.
* New: In EtesianEngine, now manage placed Pins.
(done through extractInstanceName())
* Change: In CRL::RoutingGauge::getHorizontalGauge() no longer skip PinOnly
gauges to find the reference one (same goes for vertical).
* Bug: In Hurricane::DrawingQuery::drawGo(), forgot to apply translation
on Polygon and Rectilinear.
* Bug: In Hurricane::Rectilinear, forgot implementation of getContour().
Add a new accessor getPoints().
* Bug: In CRL::Blif::load(), do not always enforce translation towards
VHDL names. When loading LEF+gds it may change the Cell names between
the two stages so the gds layout do not get added to the LEF Cell
phantom.
Now add a boolean enforceVhdl argument (may be a flag in the future).
* Bug: In ::GdsStream::operator<<(Cell*), forgot to drive the Rectilinear.
* Change: In CRL/etc/cmos/kite.conf, setup correct H/K parameters for
the Katana global router. Value copied from Knik. They give a
faster solution.
* New: In CRL/etc/cmos45/, new symbolic settings adapted to FreePDK 45nm.
Courtesy of N. Shimizu. To be used with NSXLIB.
* New In CRL::System, add "coriolis_top" to the set of pathes available
to the user.
* 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.
* 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.
* Bug: In CRL::GdsDriver::GdsStream two bugs :
1. The tm fields are int but must be casted into uint16_t in BGNLIB
and BGNSTR.
2. The mandatory LIBNAME record was missing.
3. We also force, for now the dbu to be 1000 and the UU to be 1um.
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 CRL::ParserMap, no longer recognize the file extensions
".vhdl" and ".vhd" which are true VHDL and cannot be parsed by the
"vst" (Alliance structural subset VHDL) parser.
This should solve annoying problems for the Makefiles when there
is both the full VHDL file ".vhdl" and the synthesized one ".vst"
(note that this problem do not arise when using Yosys/Blif).
* Change: In CRL::Blif, we now can add a list of Hurricane library for
the parser to look for standart cells. If the library list is *empty*
we look use the Alliance mechanism, if not, we look *only* in this
library list. This behavior is implemented in Subckt::createModel(). I
To add a library, use CRL::Blif::add(Library*).
This allow to manage symbolic or real mode loading, it may need
some rework to clarify the interface.
* 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.
* Bug: In CRL::RoutingLayerGauge::divide() & getTrackNumber(), the number
of traks crossing an edge was wrongly computed for GCells around the
zero coordinate, this was due to the change in rouding direction
around zero. It was starting to show for routing gauges with an offset.
Note: to simplificate the computation of the capacity of an interval,
all the track over a Cell are computed from (0,0). The Cell abutment
box has to be choosen relative to that. The tracks positions are fixed
all over the Cell (or chip if it is one).
* 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.
* New: In Anabatic & Katana, add the new "drag" feature.
With VH gauges used by real technologies (M1-H, M2-V, M3-H) a new
routing configuration that was not efficiently handled did appear.
While the preferred routing direction for metal1 is officially
horizontal, due to the way the standard cell must be designed,
their metal1 terminals are still verticals (or punctuals).
Thus, when connecting to them, we face the case where the metal1
terminal (RoutingPad) is vertical *and* the metal2 wire is also
vertical. With that setup, the position of the AutoContactTerminal
via12 cannot be deduced, it may range all the way over the
metal1 RoutingPad. What may define it's position is the metal3 the
metal2 finally connects to. That, is, when we have one horizontal
(the metal3) and one vertical (the metal1 RoutingPad).
The intermediate wire of metal2 can be kept to a minimum size
by "dragging" the via12 close to the via23 when the metal3 wire is
moved.
* New: In Anabatic & Katana, problem of closely vertically aligneds
RoutingPads in metal1 is managed first in PreProcess by restricting
the span of the connecteds metal3 and in _makeDogleg also by restricting
the span even more tightly (to the RoutingPad itself).
* New: In Anabatic::AutoContactTerminal, add the "drag" support.
Automatically check if the connecting segment is in the same
direction as the RoutingPad, if so, sets the "SegDrag" flag.
The dragging state can be known with the "::canDrag()" predicate.
* New: In Anabatic::AutoHorizontal, add the "drag" support.
The drag state can be known with the "::isDrag()" predicate.
In "::_makeDogleg()", when making a dogleg on a dragable segment
pass the drag state correctly and restrict the perpandicular span
of the perpandicular to the RoutingPad (though segment user constraints).
If we make a dogleg on the metal2 is it likely than we cannot go
straigth out vertically from the RoutingPad, so the new perpandicular
*is* restricted to the RoutingPad span.
Idem for AutoVertical.
* New: In Katana::Manipulator, add method "::dragMinimize()" which find a
hole where to minimize a draggable segment. We finally did not use it,
but keep it for potential further use.
* New: In Katana::PreProcess, adds a "protectAlignedaccesses()" local
function to check for vertically aligned metal1 RoutingPads, in that
case setup user constraints on the metal3 segments so they cannot
completly cover the other RoutingPad with metal2.
We also keep a "metal2protect()" function that create a fixed segment
to lock/protect a RoutingPad. Not used for now.
* New: In Katana::Session, add a RoutingPad locking event mechanism.
This allows us to request the creation of a locking (fixed segment)
over a draggable segment. Not used for now.
Lock events are processeds before all others as they create new
TrackElements.
* New: In Katana::Track, "::getNextFree()" and "::getPreviousFree()"
method to find the nearest free interval in a Track after/before a
position.
* Bug: In Anabatic::AutoHorizontal::getConstraints(), merge with user
constraints *only* if it's not an empty interval (as we use min/max
functions). Idem for AutoVertical.
* Bug: In AutoSegments_OnContacts::Locator::isValid(), the boolean test
must be inverted. Seems it never worked, but we never used it until
now...
* 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 CRL Core, etc/, update the configuration files of real
technologies. Mostly for FreePDK 45. This work is also done for
AMS c35b4 (350nm) but in a private (SoC) git repository.
Added a new parameter 'lefImport.minTerminalwidth' for the
minimum size (width) of a metal1 terminal in standard cells.
Corrected bug of the minimum trace level which must be
initialized to a great value and *not* zero;
* Change: In CRL Core, BlifParser, detect when there is no tie low
or tie high defined, issue an error (connexion left open) but
continue.
* New: In CRL::RoutingLayerGauge, new overlad of getTrackPosition()
with the parameter set of getTrackIndex(). Used to know if a
terminal is on-grid or not.
* New: In CRL::LefImport, smarter management of metal1 pins. Adds a
_pinPostProcess() function to select the external components
among the various shapes. If the gauge is VH, all the pin rectangles
are translateds into vertical segments (even if the metal1 gauge
says the tracks are horizontals).
The _pinPostProcess() function adds as external components of
a net, only the segments of a sufficent width as given in
'lefImport.minTerminalWidth' and that are on-grid.
* 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::NetBuilder, set all the attributes as private and
create accessors and mutators.
Finish virtualising all GCell build methods and transfer them
into the NetBuilderHV class.
Build methods now return a boolean to tell if the GCell was
processed or not, to allow cascading in the "big switch".
Reorganise the "big switch" in separate sections only partially
cascading.
Truly fuse the *big switch* for channel routing and over-the-cells.
Create a new method "_do_globalSegment()" to delagate the
drawing of global segments between two GCell to the derived classes.
* New: In CRL Core, AllianceFramework::getCell(), adds a new Catalog::State
flags to request the loading of a "foreign" cell. That is, a Cell which
is *not* in the Alliance libraries, but in *any* library starting from
the root library. This is a temporary hack to allow the Blif parser to
run.
* New: In CRL Core, RoutingGauge::getHorizontalGauge() and
RoutingGauge::getVerticalGauge() to avoid relying on either metal names
or depth to know the vertical and horizontal default routing
informations. They return the metal layers gauges *closests* to the
substrate which are likely to have the lesser pitch.
* New: In CRL Core, BlifParser, new configuration parameters:
"etesian.cell.zero" & "etesian.cell.one" to figure out what are the
tielow and tiehigh cells (instead of having the ones from sxlib
hardwired).
* New: In Etesian, add support for non-square routing pitchs, that is,
the lowest vertical and horizontal pitches are not equal. Needs to
work with two pitches (H & V) instead of one.
The Configuration associated class now also provides the
RoutingGauge (not only the CellGauge).
Use a new Configuration setting "etesian.feedNames" to set up
the names of the filler cells. This a string of comma separated
cell names.
* New: In Anabatic, Session::_getNearestGridPoint(), use the new
non-square grid scheme.
* New: In CRL Core, added LEF importer for real technologies. This is
still a work in progress. Exported in Python interface.
* Bug: In CRL Core, CellGauge::getRecord() correctly display DbU
attributes.
* Change: In Unicorn, mofificate ImportCell and ImportCellDialog to
support the LEF importer. Add a template layer so we can work with
loaders returning Cell* or Library*.
* Change: In Unicorn::UnicornGui::getCellFromDb(), in addition to the
Alliance loader, uses the DataBase::getCell() too (for Cells that
are *not* in Alliance).
* New: As, starting from version 5.8, LEF/DEF parser/drivers are
availables under Apache 2.0 license, integrate them inside the
project. Rewrite the Makefiles into CMakeLists.txt, build only
the C++ version. Create an entry for the LEF/DEF doc in the
documentation.
* New: In CRL Core, etc/cmos/kite.conf new routing gauge "sxlib-2M" for
two metals only technologies.
* New: In CRL Core, python/helpers/kite.py, new parameter to set the
routing gauge to be used: "kite.routingGauge" (default: "sxlib").
* Change: In CRL/AllianceFramework.cpp, forgot to put the Cell gauges
and RoutingGauges in the object Records (Inspector).
* New: In pyCRL/PyAllianceFramework.cpp, export the setRoutingGauge()
function.
* New: In Anabatic::AutoContact and the derived classes, manages wide
wires. The contact self dimension itself according to the segments
it is connected to. Special case for the AutoContactTerminal which
also read the size of the component it is anchored upon.
New refresh method "updateSize()" and flag CntInvalidatedWidth.
to compute the size.
In AutoContactTerminal, compute the constraint box according to
the width of the segment.
* New: In Anabatic::AutoSegment, flags are now implemented as "static const"
attributes of the class. The flags are stored into a uint64_t as
they are more than 32.
Added new flag "SegWide" and associated predicates.
* Change: In GCellTopology::_doHChannel() and GCellTopology::_doVChannel(),
uses the simpler overload of AutoSegment::create() in order to detect
the wire width automatically.
* New: In Katana::Manipulator, split insertToTrack() and forceToTrack()
into a one-track method and a segment level method that iterate over
the track span of the segment.
* New: In Katana::SegmentFsm, for each cost in the table, now allow access
to a specific track. So the base functions have now two parameters:
"icost" and "itrack" (has a cost can have multiple tracks in the case
of wide segments).
* Change: In Katana::TrackElement, remove the index of the element inside
it's track, as for a wide segment it will not be meaningful for the
non-base track. This means that we have to use the Track::find()
method each time instead.
Remove the wide flag, as it is a duplicate of the one in AutoSegment.
Added a getTrackCount() method to tell the number of track the
segment is inserted into. Needed in the Track destroy step to delete
a segment only when the last track that refers it is destroyed.
Added getSymmetricAxis() to correct the computation of the symmetric
base track in case of wide segment as the base track is not centered
but the the leftmost one.
* Change: In Track::insert() insert wide segments in their whole track span.
* Change: In TrackCost, create an array of costs according to the segment
track span.
* Change: In TrackSegment::create(), now activate the factory and create
wide segments.
* Bug: In Katana::AutoSegments_Perpandicular, correct the debug indentation
problem (ever shifting to the right).
* 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 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.
* 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.
* 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**.
* 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.
* 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.
* 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.
* 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 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 Bootstrap, in coriolisEnv.py no longer sets the environment
variable STRATUS_MAPPING_NAME (guessed by init).
* Change: In CRL Core, in System CTOR sets the default value for
"stratus1.mappingName" to "not_set" so the init can known it is not
set.
In etc/coriolis2/*/stratus1.conf, do not set "stratus1.mappingName".
In coriolisInit.py, now guess the value of "stratus1.mappingName"
if it has not already been set by the user. The complete setting
process is as follow (decreasing priority):
1. Setup by the user in his ".coriolis2/setting.py".
2. A "stratus.xml" file is detected in the current technological
directory (example: etc/coriolis2/65/cmos065/setting.xml).
3. Fallback value to "etc/coriolis2/stratus2sxlib.xml".
* 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.
* New: In CRL Core, in RoutingLayerGauge, adds a new parameter "obstacleDw".
It represents the distance to add from the *edge* of a blockage segment
to the next *axis* of a routing track. This was previously computed as
the pitch minus the mimimum half wire width. This works if the pitch
is *equal* to the wire width plus the minimal distance (edge to edge).
But if the wire width is less, than it leads to too great a distance
around obstacles, making them bigger than they are. And potentially
blocking everything. To summarize:
before: obstacleDw = pitch - wireWidth/2 (deduced)
after: obstacleDw = explicitly setup, usually:
pitch - max(wireWidth)/2
Modify the Alliance configuration helper and the various kite.conf
file accordingly.
* New: In Kite, in BuildPowerRails, make use of "obstacleDw" to compute
the footprint of a blockage.
* 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.
* Bug: In CRL Core, in BlifParser, recognize clocks (Alliance patterns).
* Change: In Cumulus, in RSavePlugin, "kw" manage a new "views" to
specify which views must be saved. Physical by default, but sometimes
we need logical as well. If the design contains uniquified cells,
save the logical view.
In ClockTree, abort the clock tree building if the design has no
top level clock.
* Change: In Katabatic, in GCellTopology, adds 2G_5M1 configuration.
* Bug: Kite, in BuildPowerRails, if we are not in a chip the nets
composing the H-Tree must be protecteds be blockages.
* 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...
* Change: In CRL Core, the Alliance VHDL (vst) driver was renaming the
names of Cells, Instances and Nets into their VHDL conterparts.
But if we still work on the Cell after saving it, the Net renaming
will cause touble, especially when there are DeepNets. The name
of the DeepNet is generated from the Occurrence name with the dot
separator which is *not* a VHDL valid character for name, thus
after that the DeepNet name has changed it cannot be reassociated
with the Occurrence path. This was causing double-flattening issues.
* Bug: In CRL Core, in VhdlEntity, when a scalar signal is also global,
two ScalarSignal where created, but only one can be linked as a
property on a Net. So when the one *not* linked as a property was
deleted, an infinite loop started (under Cygwin at least).
The _globals list now contains pointers to signals that are in
_signals. The _globals elements no longer needs to be deleted.
* 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...
* Bug: In CRL Core, in Vst driver, remove VhdlEntity (from Cell) and
BitProperty/Bit (from Net) with the property remove and not the
destroy() method. The BitProperty removal was completly forgotten
leading to the use of removed Signals when doing multiple saves
(hence core-dump).
* Change: In CRL Core, in Vst driver, never save as Signals the DeepNets
as they are created by a virtual flatten and do not connect any
instances at top level. Note that they will exists in the physical
file if routing layout has been created.
* Change: In Knik, in Vertex, add a "blocked" flag to signal disabled
vertexes in the grid (must not be used by the global router).
Modificate the Graph::getVertex() method so that when a vertex
is geometrically queried, if is a blocked one, return a non-blocked
neighbor. This mechanism is introduced to, at last, prevent the
global router to go *under* the pad in case of a commplete chip.
* New: In Katabatic, in AutoSegment, a new state has been added: "reduced".
A reduced segment is in the same layer as it's perpandiculars.
To be reduced, a segments has to be connected on source & target to
AutoContactTurn, both of the perpandiculars must be of the same layer
(below or above) and it's length must not exceed one pitch in the
perpandicular direction.
To reduce an AutoSegment, call ::reduce() and to revert the state,
call ::raise(). Two associated predicates are associated:
::canReduce() and ::mustRaise().
Note: No two adjacent segments can be reduced at the same time.
* Bug: In Katabatic, in GCellTopology, add a new method ::doRp_AccessPad()
to connect to the pads. Create wiring, fixed and non managed by
Katabatic, to connect the pad connector layer to the lowest routing
layers (depth 1 & 2). The former implementation was sometimes leading
to gaps (sheared contact) that *must not* occurs during the building
stage.
Remark: This bug did put under the light the fact that the initial
wiring must be created without gaps. Gaps are closed by making doglegs
on contacts. But this mechanism could only work when the database if
fully initialised (the cache is up to date). Otherwise various problems
arise, in the canonization process for example.
* New: In Katabatic, in AutoContactTerminal::getNativeConstraintBox(),
when anchored on a RoutingPad, now take account the potential rotation
of the Path's transformation. Here again, for the chip's pads.
* New: In Kite, support for reduced AutoSegment. TrackSegment associateds
to reduced AutoSegment are *not* inserted into track to become
effectively invisibles. When a segment becomes reduced, a TrackEvent
is generated to remove it. Conversely when it is raised a RoutingEvent
is created/rescheduled to insert it. All this is mostly managed inside
the Session::revalidate() method.
* New: In Kite, in KiteEngine::createGlobalGraph(), in case of a chip,
mark all global routing vertexes (Knik) that are under a pad, as blockeds.
* Bug: In Cumulus, in PadsCorona.Side.getAxis(), inversion between X and
Y coordinate of the chip size. Did not show until a non-square chip
was routed (i.e. our MIPS R3000).
* Change: In Stratus1, in st_placement.py add the ClockBuffer class for
backward compatibility with the MIPS32 bench. Have to review this
functionnality coming from the deprecated placeAndroute.py.
In st_instance.py, no longer creates the Plug ring of a Net.
In my opinion it just clutter the display until the P&R is called.
Can re-enable later as an option (in Unicorn).
* Change: In Unicorn, in cgt.py, more reliable way of loading then running
user supplied scripts. Borrowed from alliance-checker-toolkit doChip.py .
* 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).
* 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).
* 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...
* Bug: In CRL Core, in VectorPortMap::VhdlPortMap(), if the connection
was made to *non-contiguous* bits of an otherwise *contiguous* vector,
it was using a span instead of the separate bits. Now check that
bits are contiguous (delta: +1/-1) and the delta do not change of
sign.
* Change: In Etesian & Kite, the Python interface function ::setViewer()
was checking that the argument was indeed a CellViewer, but in text
mode it is None. Now, silently ignore the argument if it cannot be
converted into CellViewer.
* 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;
}
* Change: In bootstrap, in FindLEFDEF.cmake, adds my personal path where
the LEF/DEF libraries are to be found (~jpc/oa/lefdef/5.7-s038/).
* Change: In CRL Core, in LEF/DEF exporters, use the default routing
gauge and cell gauge, instead of systematically requiring "sxlib".
IMPORTANT: In order to build a *shared* library including the
*static* LEF/DEF libraries, those libraries, even if static, must
be build with the "-fPIC" flag (otherwise the compiler complains).
I have done so on my 64 bit build of LEF/DEF, but it's a completly
*local* patch. You may have to do it manually on your installations.
* Change: In CRL Core, replace duplicated libraries, even when performing
a Append/Prepend operation. Also correct a bug in library name
uniquification, event if it's no used. The policy in cas of duplicate
libraries is not completly clear for me, still.
* 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, in VstParser, support IEEE VHDL, with tokens
<library> and <use>. If "use IEEE.std_logic_1164.ALL" is present
the file will be considered to be IEEE compliant.
To be precise, the parser now support any mix between Alliance
and IEEE VHDL. So you can have both <std_logic> and <wor_bit>
in the same file, but it is unclean to do that.
The two extensions ".vhd" & ".vhdl" are supported.
The drivers still always creates Alliance VHDL.
* 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.
* Error messages are more explicit in Ap and Blif parsers
* Warns when not using tie cells
* New layer synonym in ApParser for easier format conversion
* Blif import is now on top
* 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>.
