* Change: In Etesian::SubSlice::getUsedVTracks(), now take blockages
into account for used vertical tracks.
* Bug: In Etesian::SubSlice::avoidTrack(), right free interval for
shifting was wrongly computed, effectively allowing *any* shift.
This was creating cells overlap!
* New: In Hurricane::BasicLayer & Layer, establish a two way link
between the blockage layer and routing layer. Now we can access
the routing layer from the blockage.
* New: In NetBuilderHybridVH::_do_1G_xM1_1PinM1(), added configuration
to manage pins on the north/south sides for VH,2RL.
* Bug: In NetBuilderHybridVH::doRp_xG_xM1_xM3(), correct misplaced
vertical creation (buildind invalid topologies).
* New: EtesianEngine::toColoquinte(), display histograms of the cells
widths (in pitch) before and after bloating to get a better feeling
of the behavior.
* New: In EtesianEngine, add support for track avoidance. Portions of
tracks to avoid are specified by a Box, which should flat and on
the axis of the request track. This feature is used by the H-Tree
to clear the vertical tracks under the tree from any terminal.
* New: In Etesian::Area, Slice and SubSlice, add support for track
avoidance. Exported to the Python wrapper.
* New: SubSlice::getUsedVTracks() to get a set of tracks blocked by
the cell.
* New: SubSlice::trackAvoid(), shift left/rigth the cell under the
requested vertical track. Try only to move the cell under the
track and not it's neighbor, so it assume that there is sufficient
space left or right of the cell.
* Bug: In cumulus/plugins.block.configuration.BlockConf, the Cfg
parameters may be read too early from the Cfg space into the
various sub-conf objects (like FeedsConf). Delay the reading
of the parameters in a _postInit() functions.
Modify Block and CoreToChip to call _postInit().
* New: In cumulus/plugins.block.configuration.BlockConf._loadRoutingGauge,
allow the cell gauge name to differ from the routing gauge name.
* New: In cumulus/plugins.block.configuration.FeedsConf, allow to
select the default feed to be used with 'etesian.defaultFeed'
parameter.
* New: In cumulus/plugins.block.spares.BufferPool, allow to control
whether or not we want tie to either side of the pool.
(for latch up).
* New: In cumulus/plugins.block.HTree._connectLeaf(), add support
for track avoidance.
* Bug: In cumulus/plugins.block.HTree._connectLeaf(), the TL2 contact,
the one on the *top* auxiliary buffer seemed to have been badly
positioned until now (too low, not using tl2Y).
This is strange because it should have caused disconnections,
but I didn't see it in the wiring and the regressions tests didn't
flag anything wrong. Still a bit weird and worrying.
* New: Hurricane::ErrorWidget, new widget exported to Python to replace
helpers.io.ErrorWidget.
* New: Hurricane::AboutWindow, new window exported to Python to replace
cumulus/plugins.aboutwindow.AboutWidget.
* New: In Hurricane::RoutingPad, added support if the supporting component
is a Pad. The source/target positions are computed according to the
most likely direction.
Change the _getEntityAsComponent() function into an inline template
_getEntityAs<T>().
Change the flags from an enum to static const uint32_t.
* Change: In Anabatic::Configuration, use _getEntityAs<T>.
* Change: In Anabatic::Dijkstra, use _getEntityAs<T>.
* Change: In Anabatic::NetBuilder, use _getEntityAs<T>.
* Change: In Katabatic::LoadGrByNet, use _getEntityAs<T>.
* Change: In Katana::ProtectRoutingPads, use _getEntityAs<T>.
* Change: In Bora::AnalogDistance, use _getEntityAs<T>.
* Change: In Etesian::EtesianEngine, use _getEntityAs<T>.
* New: Isobar::PyAttributesHolder, a PyObject with only a dictionary
to hold the attributes associated to a DBo.
* New: Isobar::PyHolderProperty, the Property that encapsulate
PyAttributesholder.
* New: Isobar::PythonAttributes, the extension to simplify the
management of the PyAttributesholder.
* Change: In PyEntity, now use a dedicated tp_getattro and tp_setattro
to delegate the Python attribute access towars the PyAttributesholder.
* New: In hurricane/doc & documentation, update docs regarding Python
attributes managment.
In SelectorCriterion & SelectorCriterions, when selecting a Net occurrence,
we where storing the Net only. This was fine if the Net was belonging to
the Cell's top level. But when it was an occurrence of a non-top level
net, this was creating the elusive incoherent Occurrence problem.
Now we truly store the occurrence of the Net, to be accurate, the root
of the HyperNet.
* Change: In SelectorCriterions::add(), the Net* argument is replaced
by a Occurrence of Net. Must be an HyperNet root occurrence.
Same goes for SelectorCriterions::remove().
* Change: In CellWidget::select(), when called with a Net occurrence,
select the whole HyperNet components.
* Change: In NetSelectorCriterion, now use a Net occurrence instead
of directly a Net. Must be an HyperNet root net occurrence.
* Change: In PyLayoutGenerator, in the method definition of the class,
replace the METH_STATIC flag by METH_CLASS for setVerboseLevel().
There may be more of it elsewere, but as they didn't seem to
have been triggered, we will see as it happens.
This was the reason why we, sometimes got "UNCONNECTED" errors in the
VHDL PORT MAP statements. This was the remnants of the originally
connected driver.
* Bug: In Etesian::BufferTree, as the root driver is disconnected from
all the sinks, but the top tree buffer, we may end up with
unconnected signal on instances that were using it.
So now, call BufferTree::rcleaupNet() to remove the Net in
the Cell that where used to "transmit" the original driver.
* Bug: In Etesian::BufferTree, no longer use a _isDeepNet attribute
guessed from the occurrences pathes of the RoutingPad, but
trust the Net::isDeepNet() method.
The decoupling of the cell gauge and the routing gauge implies that
the METAL2 & METAL3 terminals of macro blocks cannot be aligned on
the routing tracks anymore. That is, an horizontal METAL2 terminal
will not be on a track axis, but offgrid, so we no longer can use
a METAL2 horizontal segment to connect to it. Making an adjustement
between the offgrid terminal and the on-grid segment has proven
too complex and generating difficult configuration for the router.
Moreover, METLA2 terminal could be fully inside a METAL2 blockage.
So now, when the gauges are decoupled, we connect the METAL2 and
METAL3 the same way we do for METAL1: *from above* in the perpandicular
direction and using a *sliding* VIA. We assume that those kind of
terminals in upper metals are quite long.
* New: In Hurricane::Rectilinear, export the isNonRectangle() method
to the Python interface.
* New: In CRL::RoutingGauge, add function isSuperPitched() with the
associated boolean attribute. Set to true when each pitch of
each layer is independant (not low fractional multiples).
* New: In AnabaticEngine, add the ability to temporarily disable the
canonize() operation (mainly used in dogleg creation).
* New: In AutoSegment::canonize(), do nothing if the operation is
disabled by AnabaticEngine.
* Bug: In Session::_revalidateTopology(), disable the canonization
during the topology updating of a net. Too early canonization
was occuring in makeDogleg() leading to incoherencies when
performing the later canonization stage over the complete net.
Mostly occured in the initial build stage of the net.
* New: In GCell, add function postGlobalAnnotate(), if a layer
is fully blocked (above 0.9), typically, under a blockage,
add a further capacity decrease of 2 on the edges. So we may
handle a modicum of doglegs.
* Bug; In GCell::addBlockage(), removeContact(), removeHSegment()
and removeVSegment(), forgot to set the Invalidated flag.
This may have lead to innacurate densities.
* Change: In GCell::updateDensity(), more complex setting of the
GoStraight flag. This flag is now set if we don't have two
*contiguous* below 60% of density. We need free contiguous
layers to make doglegs.
* New: In NetBuilder, now manage a current state flag along
with the state flag of the *source* GCell. This flag is used
to tell if the GCell needs it's *global* routing to be done
using the upper layers (METAL4 & METAL5) instead of the
lower ones.
* New: In NetBuilder::setStartHook(), set the state flag of the
GCell to ToUpperRouting when processing a global routing
articulation and one of the base layer is obstructed
above 0.9.
In GCell with terminals, also set ToUpperRouting when there
are some in METAL2 / METAL3 and the gauge is not super-pitched.
* New: In NetBuilder, function isInsideBlockage(), to check if a
terminal is completely or partially enclosed in a blockage.
* Change: In NetBuilderHV::doRp_AutoContact(), remove support for
trying to put on grid misaligned METAL2/METAL3.
Instead systematically access them from above.
Do not cover with fixed protection terminals that are already
enclosed in blockages.
* Bug: In NetBuilderHV::doRp_AutoContact(), always add the terminal
contact in the requested GCell and not the target/source one,
in case the terminal span several GCells.
* Change: In NetBuilderHV::doRp_Access(), create the local wiring
according to the RoutingPad layer.
* Change: In NetBuilderHV::_do_xG(), _do_2G(),
create the global wiring in upper layers, according to the
ToUpperRouting flag.
* Change: In NetBuilderHV::_do_xG_xM3(), now delegate to
_do_xG_xM3_baseRouting() and _do_xG_xM3_upperRouting() if the
density at terminal level is above 0.5.
* New: NetBuilderHV::_do_xG_xM3_baseRouting() and
_do_xG_xM3_upperRouting() separated function to manage the
local routing.
* Change: In NetBuilder::_do_globalSegment(), if the currently
processed GCell or it's source is in ToUpperRouting mode,
move up the global segment. Do *not* use the moveUp() function
which would create doglegs unwanted at this stage.
* New: In KatanaEngine::annotateGlobalGraph(), call postGlobalAnnotate()
on the GCell after the blockages have been taken into accound to
add the penalty.
* Bug: In Track::getPrevious(), correctly manage the 0 value for the
index argument. Strange it didn't show earlier.
Same goes for Track::expandFreeInterval().
* Bug: In NetlistModel::setCell() template, forgot to send the
"layoutAboutToBeChanged" signal before disconnecting the
netlist datas. This seemed to go unnoticed until ported
under Qt5. Was generating strange random core dump when
running the engines with a net kept selected. Disgraceful
crash during demos...
* Bug: In Selector::_preDestroy(), *do not* iterate over the _cellWidgets
map as we destroy it's elements! We end up in destroyed ones...
Instead destroy the first one until the map is empty.
* Change: In CellWidget::_redraw(), the boundaries, that is, instances
abutment boxes where drawn *after* everything else, so they where
hiding more interesting informations (especially at low zoom level)
like routing wires.
Now draw them *first* so they are *below*.
* Change: In CellImage::setScreenCellWidget, fully copy the display
settings from the reference widget (not just part of them).
* Bug: In CellImage::toImage(), if the abutment box of the displayed
cell is not *fully* includer in the viewer area, do *not* try to
reframe it. The reframe() method seems to be buggy, works OK
just without calling it.
* Bug: In Viewer::SelectionPopup(), the window attribute
Qt::WA_DeleteOnClose was *not* cleared. So the window was deleted
after first use while it was though staying allocated.
Again, generating weird crashes.
Took the occasion to slightly redesign the behavior to select
and highlight individual components.
* Bug: In Isobar3::PyTypeManager, the accessors _getCppTypeName() and
_getPyTypeName() where returning string *by value*, hence, short
lived copies.
But, in _setupPyType() and _addToModule(), as we interface with
the Python/C API, we extract the c_str(). Which where removed as
we used temporary objects. Leading to memory corruption and weird
crashes.
Now returns "const string&" so the c_str() stays allocated.
* Bug: In CellWidget::DrawingQuery::drawGo(), the display condition was
wrong, it was requiring *both* width & height to be above the display
threshold. Either one is sufficient to activate the display.
Was causing the selective diseapearance of gates at low zoom level
and printed version.
* Change: In CellPrinter, force the display threshold to one pixel in it's
internal CellWidget used for printing.
WARNING: We are partially duplicating the informations pertaining
to the Alliance catalog (stored in the Catalog property)
directly into the Cell. This is needed for Flexlib which
is not using the Alliance loading mechanim. Ideally the
Catalog information should be moved into the Cell.
* New: In Cell, add new state flags Diode, PowerFeed (in addition to
Pad & Feed).
Export flags setter/getter to Python. For Flexlib usage.
* Change: In AllianceFramework::getInstancesCount(), correctly skip
Diode & Feeds based on Cell flags. Those flags must correctly
be set in the various Flexlib_fix.py scripts.
NOTE: Due to Python pathes, the NDA.common is *not* seen, even by NDA
protected configuration. They are using the non-NDA one. No harm
in that, just need to be known...
* New: In DeepNet, add an DeepNet::Uplink property on the HyperNet
root net Occurrence so we have a direct two-way link between
the top (flattened net) and the root of the HyperNet.
Down link is ensured by the Occurrence, up link by the Uplink
property.
* Change: In Cell::getDeepNet(), now use the DeepNet Uplink property
instead of looping over *all* top nets. This was the cause of the
terrific slow down in PowerRails, especially on flatteneds designs.
* Bug: In all CMakeLists.txt, it seems I was doing a worng use of
target_link_library(). No longer add dependencies to the C++ base
library but instead either to the Python associated module or
to the final binaries. This was inderectly causing the linking
problem related to Python (which was a misdirection).
* Bug: Typo in FindLibexecinfo.cmake, do not use FindLib[E]xecinfo.
* Change: In CRL/ccore/CMakeLists.txt, activate SKIP_AUTOMOC on
bison/flex generated files.
* Bug: In viewer/PyHApplication, do not delete the C++ object in
the Python destroy method.
* Bug: In Common.h, makes the INSPECTOR_PV_SUPPORT to generate a getRecord()
by *value* instead of *by reference*. Seems the overload resolution
system has changed and discriminate between them using now the exact
match.
This was causing InspectorWidget::setRootoccurrence() to fail, the
getRecord(Occurrence) not corectly resolved always returning NULL.
* Change: In Occurrence, now use INSPECTOR_PV_SUPPORT (instead of PR).
* Change: In SelectionPopup, added a _cellWidget attribute to be able
to call setShowSelection() in ::mouseReleaseEvent(), same as for
SelectCommand.
* Bug: In SelectionWidget::changeSelectionMode(), reset the _updateState
to ExternalEmit in *all cases* at the end of the function call.
Failing to do that was another cause for the selection check box
to desinchronize.
* Bug: In CellWidget::drawGrid(), the scaling of grid was never recomputed
according to the zoom level. So in low zoom, it was too fine and
hidding everything underneath...
Now always display between 1 and 10 lines. Lines are put on the
grid step.
Makes the grid draw in dotted lines, seems to looks nicer.
* Bug: In CellViewer::setShowSelection(bool), this slot is connected
to the hidden 's' menu key. It was toggling state according to
the state of the *menu key* (Qt) which was *not* kept in synch
with the state of the CellWidget. So it was causing desinchronized
selection visibility toggle. Now, ignore the state of the menu
and toggle the CellWidget state directly.
* Bug: In Selector::attachTo(), when adding the new CellWidget to the
map<>, the initial flag must be Selector::Selected instead of 0,
so we see it.
* Change: In CellWidget & ControllerWidget, adjust the default size of
the widgets (to better suit my display...).
* Change: In Hurricane::SharedPath, the hash for the shared pathes, which
serves for Map<> storing, were computed "on the fly" at each
::getHash() call, and were involving recursive calls of all the
hashes along the components of the shared path. This is terribly
slow especially in a design with a deep hierarchy (typical case
LS180).
Now, at the cost of one supplemenental unsigned long in each
SharedPath, it is only computed once in the constructor, and is
no longer recursive (only access the *first* tail, if any).
As a consequence, the re-display computation delay becomes
bearable. But also speed up any transhierarchical walkthough.
This field has been deprecated in Python 3 and no longer exists at all
in Python 3.9, causing a build error.

Note: We don't suppress warnings due to unused variables or functions,
as we may need them later or in debug mode...
* Change: In Hurricane::DBo::~DBo, add a noexcept(false) because
constructed by default destructor of derived classes seems to
loosen it. The right solution whould be to explicitely define
all virtual destructors (too lazy for now).
* Change: In Viewer::Script, replace the deprecated
PyModule_GetFilename() by PyModule_GetFilenameObject(), Unicode
support again...
