* 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.
