* Bug: In CRL.python.coriolisInit(), when it's not set, the stratus1.mappingName
configuration variable is equal to "" and *not* "not_set".
* Bug: In Etesian::EtesianEngine::toColoquinte(), followup of the previous
bug, bad FIXED/PLACED test when the AB is set.
* Bug: In Etesian::EtesianEngine::toColoquinte(), when the master Cell of
an instance has an abutment box, this instance *must* be placed so we
can compute the positions of its own instances. Throw an error if it's
not the case.
* Bug: In Hurricane::Net::setExternal(), do not perform an UpdateSession
inside this function, it leads to unbearibly slow operation in the
clock-tree plugin.
* Bug: In Kite, backport corrections done in Katana and also relevant
for Kite.
* New: In Cumulus.ChipPlugin.py add support for Python profiling with
cProfile. Disabled under normal operation, but will certainly come in
handy sometimes.
* Bug: In Hurricane::JsonWriter, add support for "long long". Needed on
32 bits architectures to write DbU that are now int64_t which
resolves to "long long".
* Bug: In Hurricane::DbU, replace long by DbU::Unit (aka int64_t) in all
remaining occurrences.
* Change: In Hurricane::DbU::getValueString(), rewrite using ostringstream.
* Change: In Hurricane, in PyHurricane.h, PyAny_AsLong<> template to
convert any kind of Python integer into DbU, making sure we always
use 64 bits integers (long long for 32 bits and long for 64 bits).
PyDbU_FromLong<> template to peform the reverse, DbU to Python
integer in 64 bits (either using PyLong_FromLong() or
PyLong_FromLongLong()).
* Bug: In Isobar, in PyArg_ParseTuple(), never use the "l" direct
converter when reading a DbU. Instead read a PyObject then convert
using PyAny_AsLong<>. This ensure to never do a truncature.
* Bug: In CRL::ToolBox::attachPlugOrPin(), simply returns when there is
no plugs/pins to connect instead of doing an assert().
* Change: In Hurricane, more informative trace information for Python
ProxyProperty managment.
* Bug: In Stratus, when merging nets with the "<=" operator some table
of lookup of Hurricane Net are not updated correctly. As I don't
understand well enough the Stratus code **is is not corrected**.
* Change: In bootstrap/FindBootstrap.cmake, new setup_qwt() macro to
link with the Qwt library build with Qt 5 *or* Qt 4 and not the
first found.
* Change: In Hurricane/DbU, uses <int64_t> instead of <long> to always be
sure that we use 64 bits integers for coordinates.
* Change: In Katana/KatanaEngine::_gutKatana() checks that the
RoutingPlanes have been allocateds before trying to delete them.
* New: In Anabatic::AutoContact, added forceOnGrid() method to allow
a AutoContactTerminal to be set (and fixed) outside it's constraint
Box. Be aware that this may generate gaps in the routing.
Stored using the UserNativeConstraints mechanism.
* New: In Anabatic::Session() new method getNearestgridpoint() to
easily compute the nearest grid point from a position.
* Change: In Anabatic::AutoSegment::_revalidate(), use layer mask to
compute the spin of the segment instead of the layers (more robust
for analogic).
* New: In ::GCellTopology::doRp_Access() new method to create terminal
contacts in _doDevice(). Issue more warnings and force the terminal
to on grid (even if it create gaps). This a temporary hack.
* 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.
Restriction on vertex are now correctly done.
* Change: Constants
There is only one type of Strut.
* New: LoadGlobalRouting
Detailed Routing can be performed for analog circuits.
The router does not take into account analog constraints yet.
Warnings on "metal2" should be corrected in the future.
Types of GCell considered by the router are: Device, VChannel/HChannel and Strut.
The analog circuit MUST be organized in a slicing structure.
* Bug: In Anabatic::AutoHorizontal::getGCells(), the y coordinate used
to perform the line probing for neighboring GCells, cannot use the
segment constraints because they are not correctly set this early.
Instead we have to rely on the global router having put them in the
correct position (i.e. at the center of the GCell side).
The y position must also be epsilon-decreased if it is on the
border of the nothernmost GCell.
This apply to AutoVertical as well.
* Change: In Anabatic::GCellTopology CTOR, when counting the RoutingPads
of a GCell, compare gauge layers using their masks instead of the
Layer itself. This allow for Analogic layers to be recognizeds.
* Change: In Anabatic::Autocontact, replace getMinDepth() and
getMaxDepth() by getDepthSpan().
* New: In Anabatic::AutoSegment::canMoveUp(), add an optional check of
low up density (Flags::CheckLowUpDensity). Allows to move up a
segment if the up density is (very) low, and in this case it's more
efficient than breaking it to fit in the lower layer.
canMoveUp() is now able to perform the same work as canPivotUp()
if *not* supplied the flag Flags::IgnoreContacts.
* New: In Katana, in GlobalRouting::DigitalDistance() now take into
account the cost of a VIA (currently set to 2.5). Need to known the
Net currently routed in the DigitalDistance object itself.
* Change: In Katana::Track::Element::canPivotUp(), now also takes a flag
parameter.
* Change: In Katana::Manipulator, new flag IgnoreContacts to mirror the
one of Anabatic.
* Change: In Katana::SegmentFsm, allocate once a Manipulator object instead
of many times on the fly.
In SegmentFsm::_slackenGlobal(), in the slacken state, if the up
density is (very) low, bypass to move up instead of slackening.
This solve better the routing of the control part of the register file.
The register file having a pathological case of terminal placement:
many punctual terminals aligneds in METAL2 *and* a grid of METAL2 and
METAL3 blockages near below...
* Bug: In Katana::Session::_revalidate(), after removing the zero-length
segments, forgot to re-order the track, leading to many stranges effects
as the indexes where no longer coherent in the Track.
* Change: In PyHurricane.h, in HCATCH macro, show the backtrace when
catching a C++ exception. No need to use the "hex" stream manipulator
if we cast into (void*).
* Bug: In Cumulus & Stratus, now that creation of Hurricane objects must be
enclosed in UpdateSession, has to adds them into Python code.
* Bug: In Anabatic & Katana, in the global routing stage suspend the timed
bewteen ripup steps instead of resetting it.
* Bug: In Anabatic::RawGCellsUnder, *again*, the north and east borders
of the whole area *are* includeds (shut up disgraceful warning).
* New: In Anabatic::GCell, add a display mode to select between boundary
display (for analogic) and density display (for numeric).
* Bug: In KatanaEngine::runGlobalRouter(), do not check if an Edge cannot
be desatured when the vector or overloaded Edges is empty.
(one less disgraceful warning)
* New: In GraphicKatanaEngine::drawGCell(), support for drawing the GCells
in density mode. Use the fire scale and the MaxDensity mode.
Setup the GCell drawing mode in GraphicKatanaEngine::initGCell().
* Change: In GraphicKatanaEngine::drawEdge(), adjust the various thresholds
for showing the Edge and its label.
* New: In CRL Core, adds "anabatic.gcell.displayMode" to the set of Anabatic
parameters.
Adjust the showing threshold for GCells in "display.conf" so when the
zoom level is low, we still can see the density map.
* New: In Hurricane::UpdateSession, added "reset()" static function to
close all the currently opened sessions.
* New: In Hurricane::ExceptionWidget::catchAllwrapper(), close all
pending UpdateSession if the user choose to resume.
* Change: In Hurricane::Go, instead of immediatly materializing a newly
created Go (inserting it in a QuadTree) delay it until the closing
of the UpdateSession. We call "invalidate()" in "_postCreate()"
instead of "materialize()". This way, the abutment box of Gos is
taken into account only when the session is closed. There was a
problem when the abutment box was changing after the object creation
misleading the algorithm of the QuadTree. This was occuring only
when an object was created, not modificated, because in the later case
the Session mechanism was used. Now, the Session mechanism is used
in all cases.
As a side effect, it will speed up the parser by making all QuadTree
insertions in one step.
* Change: In Hurricane::JsonCell, forgot to call Cell::materialize() when
the Cell is completed (as was done in ordinary parsers). The call is
made in the destructor of the JsonCell.
* Change: In Hurricane::Cell, add QuadTree in the inspector support.
* Change: In Anabatic, remove GraphicAnabaticEngine, PyGraphicAnabaticEngine,
PyAnabaticEngine (but keep PyAnabatic for constants exportation)
and GlobalRoute (moved to Katana). Drawing methods for Edge & GCell
are moved into GraphicKatanaEngine.
* Bug: In Anabatic, in AutoHorizontal & AutoVertical, native constraints
must use GCell::getConstraintsUMax().
* Bug: In Anabatic::GCell, correct terribly bad implementation of
both getConstraintUmax().
In getSide(), use getConstraintUMax().
* Bug: In Anabatic::AutoContact, setCBUMax() must be set using the GCell
getContraintUMax().
* New: In PyAnabatic, export the various Engine constants.
* Change: In Katana, in TrackElement and derived classes, add a getSegment()
method for easier access to the underlying Hurricane segment.
* New: In PyKatanaEngine, export the loadGlobalRouting method which was
missing (for use by Unicorn/cgt).
* Bug: In Dijkstra::_materialize(), in some special case a connex component
can is reached by two (or more) vertexes. But of course it will be
connected only through one, all others must be discarteds. The right
one will have it's connex id set, all the others will stay to -1.
So stop any backtrack when the first neighbor of a starting point
has it's connex id *not* set.
* Bug: In Anabatic::GCell, new functions getConstraintUMax() to return the
correct bounding box for the last north/east GCell. The GCells do not
own their north/east edges, except for the last ones. Thoses functions
must distinct from getUMax() because for them, the shrink is always
applied. getConstraintBox() uses the "getConstraintUMax()" functions.
* Bug: In Anabatic::AutoContact, initialize the constraint box from the
new GCell::getConstraintUMax(), to manage correctly the boundaries
of the nothernmost & easternmost GCells. The problem was showing for
pins on the north/east side of a circuit, the constraint
* Bug: In Anabatic::AutoContactHTee, Anabatic::AutoContactVTee and
Anabatic::AutoContactTerminal forgot to call the _preCreate() function
in the various create().
* Bug: In Matrix::getUnder(), if on the N/E boundary, decrease by one to
be enclosed in it.
- Modified: Matrix is now correctly updated for irregular floorplans.
Dijkstra:
- Modified: Source and Target contacts are now correctly chosen in _materialize.
