In Anabatic/Katana, add support for VH gauges (real technos).
* Change: In Anabatic::AutoContactTerminal::getNativeConstraintBox(),
when the anchor is a RoutingPad (which must be always the case),
perform the true computation of it's position based on the
segment occurrence. It is a important change, previously the
area was in fact the "center line" of the connector while now
it is really an area (mandatory for "half-offgrid" terminals of
real technologies).
The change is not complete yet, the area should be shrinked
by the half size of a VIA, because the area applies to the center
coordinate of the VIA (to be done quickly).
* Bug: In Anabatic::AutoContactTurn::updateTopology(), when a dogleg
is created (restore connexity after a layer change) the layer of
the VIA, based on the segments it connects to must be re-computed
*after* the dogleg has been made.
* Change: In all files of Anabatic, when comparing two layers, no longer
use the Layer pointer itself, but the layer mask. This allow a
transparent management of both real and symbolic layers (which
do share the same mask). Real metal layers (not VIAs) will be
BasicLayer and symbolic metal layers will be RegularLayer.
* New: Anabatic::Configuration::selectRpComponent(), select the best
RoutingPad component for metal1 terminals. Look for the metal1
component with the biggest accessibility on-grid.
RoutingPad using other metals are left untoucheds.
* New: New function Anabatic::Vertex::getNeighbor(Edge*) to get the
neighbor Vertex through an Edge*. This method allows to write
clearer code as we no longer need to access the neighbor through
the underlying GCell.
Also add proxies for GCell methods in Vertex.
* Bug: In Anabatic::Dijkstra::_toSources(), in the ripup stage, when
a component with multiples vertexes is reached *and* two of it's
vertexes are reached *at the same time* (one from which we backtrack
and one still in the queue) extraneous edges may be created by
_materialize(). Case occurs on snx/c35b4, "abc_5360_n903_1".
To solve this, Dijkstra::_toSource() is modificated, the "from"
edges of the newly reacheds vertexes are reset to NULL, *except*
for the one we will be backtracking from. That is, the one given
in the source argument.
* Change: In Anabatic::NetBuilder class, put the various Hooks and
RoutingPad sorting functions as class ones.
* Bug: In AutoSegment::setLayer(), raise the SegInvalidatedFayer flag.
This unset flag was causing AutoContactTurn::updateTopology()
to not work as expected and making gaps, this was the cause of
the last remaining warnings about layer connexity.

First working recursive place & route (Libre-SOC ALU16 benchmark).
* New: In Hurricane::Cell::isLeaf(), a leaf cell was defined as one
without instances. Now it can be software defined with the
"FlattenLeaf" state. If it is flagged "flatten leaf" is will be
considered as a leaf by the trans-hierarchical walkthrough.
This flag is also set for Cells in the Alliance CATAL.
* New: In Hurricane::Cell_LeafInstanceOccurrences::progress(), add a
test to prune leaf cells.
* Bug: In Hurricane::getComponentOccurrences(), when calling the
locator constructor, the "withLeafCells" argument was forgotten
and was getting the value of "doExtraction" (wich, fortunately,
was the same).
* Change: In Hurricane::HypreNet_LeafPlugOccurrences::progress(),
prune the leaf cells instead of the terminal ones.
* Change: In Hurricane::HypreNet_ComponentOccurrences::progress(),
prune the leaf cells instead of the terminal ones.
* New: In Hurricane::Cell, add a "useFlattenLeaf" mode to take into
account or ignore the "FlattenLeaf" flag when doing trans-
hierarchical walkthrough.
Not sure if it shouldn't be systematic.
* New: In Etesian::toColoquinte() and other, activate the "FlattenLeaf"
mode for all walkthough. So we can stop at already placed sub-blocks.
* Bug: In Etesian::toColoquinte(), when placed sub-block where present,
the number of instances was under estimated, so the instance array
was oversized and the end went unitialized. So we were getting all
kind of strange behavior from Coloquinte...
Now throw an exception if the number of instances differs from
the computed size.
* Bug: In Etesian::toColoquinte(), as for the instance array, now
correctly compute the size with the ecluded nets (supplies, clocks).
* Bug: In Etesian::resetPlacement(), event if the Cell is unplaced,
go through the instance list to remove the potential feed cells.
The netlist is written back after placement *with* the feed
cells added. So, when loading again, they where cluttering the
netlist and giving feed redefintions warning. They also generated
erratic behaviors.
* New: In Anabatic::NetBuilderHV, added configurations for:
* 1G_1M1_1PinM3
* 1G_xM1_1PinM2
* 2G_xM1_1PinM2
* doRp_AccessNorthPin
* New: In Anabatic::NetBuilderHV, added Pin management in SingleGCell.
* Bug: In Anabatic::NetBuilderHV::_do_xG_1PinM3(), the North/South
global routing configuration was forgotten (only East/West).
* Bug: In Katana::TrackFixedSegment, the blockage net was a static
variable initialized at the first run. So we were getting stuck
with the blockage net of the first cell to be routed. Of course,
it did show only when Katana was run multiple times in the same
process.

* Bug: In AutoSegment::setLayer(), raise the SegInvalidatedFayer flag.
This unset flag was causing AutoContactTurn::updateTopology()
to not work as expected and making gaps, this was the cause of
the last remaining warnings about layer connexity.

Anabatic transient commit 18. Port of Kite (Katana), Yeah, Baby! Yeah!
* Bug: In Hurricane, in StaticObservable::getObserver(), if the slot
pointer is NULL, do not try to access the owner. Returns NULL, so
the caller can be aware of the situation...
* Change: In Hurricane, in BreakpointWidget & ExceptionWidget some
cosmetic changes (fonts and window sizes).
* Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account
the constraints from the source AutoContact, as it holds the constraints
transmitted by the RoutingPads and sets up by propageConstraintsFromRp().
It is likely to be a bug affecting the original Katabatic as well.
* Change: In Anabatic, in RawGCellsUnder(), check that the segment is not
completly oustside the cell abutment box and truncate the coordinates
to the part that is inside. Use the "shrink" if we reach the east/north
border.
* Change: In Anabatic, in Configuration, no more decorator because we will
use a true derived relationship. Katana *derives* from *Anabatic* and do
not *decorate* it, so the Configuration can do the same. It also implies
that we directly create a Katana engine, not an Anabatic one.
* Change: In Anabatic, in Session, do not allow the opening of the Session
in a standalone fashion (with a static method). Instead it must be opened
using the relevant method of the Anabatic/Katana engine. This ensure we
are opening the right Session type.
* Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment
is not part of the collection by default, but will be included if the
Flags::WithSelf is set.
* Change: In Configuration, all the flags value are now defined in two steps.
Declared in the header and initialized in the module. This is to prevent
the fact that on some cases, in relation with the Python "extern C" part
modules, we need a true allocated variable. It was causing weird linking
problems.
A side effect is that they can no longer be used as entry is switches,
have to replace them by if/else.
* New: In Anabatic, new GCell::getNeighborAt() utility function.
* Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with
the grid type... Back annote all the edges capacity (north & east) with
the reserved local capacity.
* New: Complete portage of Kite over Anabatic. The new engine is christened
"Katana" for Kite-Analogic. When it's capabilities and performances
will be on a part with Kite, it is to completly replace it (and take
back the "Kite" name). Preliminary tests seems to show that, contrary
to intuition (because built on a more complex/slower grid), it is even
slightly faster than Kite 8-).

Configuration::Configuration ( const CellGauge* cg, const RoutingGauge* rg )

Corrections in the Dijkstra global routing (ripup) mechanism.
* Bug: In Anabatic::Dijkstra, the degree of a vertex (the number of neighbors
belonging to the same net) was miscalculated. This was leading, in the
materialize step to some feed-through vertexes not being broken.
Leading in turn to incomplete transformation of the detailed routing.
Also in _trackback(), the degree of the first vertex we were backtracking
from was not incremented.
* Bug: In Anabatic::Dijkstra::materialize(), systematically use
GCell::breakGoThrough() on both source and target. This is needed when
we are in the ripup phase as both source and target can be go-through.
This was also leading to incomplete detailed routing transformation.
* Change: In Anabatic::Edge::ripup(), ripup one third of the segments instead
of thoses exeeding the global length threshold. This way we are sure to
desaturate an edge. Needs to be further calibrated.
* Change: In Aanabatic::GCell::breakGoThrough(), no longer return NULL.
Return existing gcontact if any. Break if it is a go-through and create
a new gcontact in last resort. Maybe rename this function.
* New: In Anabatic::Configuration, new parameters:
- anabatic.edgeHScaling, to adjust the length of the horizontal edges
relative to the vertical ones (this is a ratio).
- anabatic.globalIterations, set the maximum number of ripup passes
of the global router.
* New: In CRL/etc/*/kite.conf, added new parameters anabatic.edgeHScaling
and anabatic.globalIterations.
* New: In Katana::GlobalRoute::DigitalDistance, take into account the new
edgeHScaling factor. Must be used when the capacity of V-edges differs
greatly for H-edges (case of AMS 350nm c35b4 for instance).
* Bug: In Katana::GlobalRoute::DigitalDistance, the historic cost is
computed for an edge length of "1". Must be multiplicated by the
current edge length to have any measurable effect.
This bug is finally explaining why the ripup was producing the
same solutions over and over, the historical cost was negligible!

Added core2chip support for Phenitec80.
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.

ISPD05 loading speed issues. IO PAD support for LEF importation.
* 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.

Added support for 2-Metal block routing in Anabatic & Katana.
* New: In AnabaticEngine::invalidateRoutingPads() this method is a temporary
workaround for a Hurricane problems. When an instance is moved, the
RoutingPads that use it must be moved accordingly, but they are not
invalidated so they stay in the wrong QuadTree.
New method ::_resizeMatrix() to be called when the associated Cell
is resized.
* Bug: In AutoHorizontal::getConstraints() and AutoVertical::getConstraints(),
the *target* constraints where never merged.
* Change: In AutoHorizontal::getCells() and AutoVertical::getGCells(),
now return a boolean to tell if it was ok (must not encounter a NULL
GCell while progessing from source to target).
* New: In Anabatic::Configuration and Anabatic:Session, create new methods:
- getDHorizontalLayer()
- getDhorizontalDepth()
- getDHorizontalWidth()
- getDHorizontalPitch()
And so on for Vertical and Contact.
They supply depth-independant informations about the H/V layers to
build the initial detailed routing.
The AutoSegment::create() methods have been modificated accordingly.
* New: In Anabatic::GCell, add two new types "StdCellRow" and "ChannelRow"
for implementing 2-Metal blocks.
Rename the GCell::setXY() method in GCell::setSouthWestCorner(),
move the contents of GCell::updateContactsPosition() into it and
suppress it.
WARNING: In case of a GCell shrink this may cause problems. But for
now we only expand...
New method GCell::getNetCount() to count the number of Net going
though the GCell.
* Change: In Anabatic::Edge, add specific support for capacity of 2-Metal
routing channels.
* Change: In Anabatic::Dijsktra various methods, replace the "gcell->isMatrix()"
calls by "not gcell->isAnalog()". Add more check so that the methods
pertaining to the analog routing (GRData) are not called in digital
mode.
* New: In Anabatic::Dijkstra::materialize(), add support for 2-Metal specific
cases. That is, always break in case of vertical pass-through or
U-turn. The global routing must always be broken in H-Channel.
* New: In Anabatic::GCell & Anabatic::Edge, make use of the Session mechanism
to ensure the revalidation. The "::revalidate()" method is then moved
as "::materialize()" (overload of Go) and "::_invalidate()" becomes
"::invalidate()"
* Change: In LoadGlobalRouting, cosmetic rename of SortHkByX in SortHookByX.
* New: In GCellTopology, added support for building 2-Metal topologies.
* ForkStack is now an object attribute as many methods do need it.
* To push segments/hook on the stack, a new method "push()" is
available. Perform NULL and fromHook checking. Can also setup
_southWestContact or _northEastContact if it is the "from" edge.
* N/S/E/W edges are now vector as in digital channel mode there
can be more than one.
* Added build topological build methods:
- doRp_2m_Access() RoutingPad stem access.
- _do_2m_1G_1M1() North or south access.
- _do_2m_2G_1M1() North AND south access.
- _do_2m_xG() H-Channel routing.
* New: In Anabatic::Matrix, new ::resize() function, as Cell can be resizeds.
* New: In Anabatic::Vertex, new static method ::getValueString() for a
friendly text rendering.
* New: In Katana::DigitalDistance, support for channel routing.
* Change: In KatanaEngine::digitalSetup() and KatanaEngine::runGlobalrouter(),
for channel routing, calls to setupPowerRails() and
protectRoutingPads() must be called after the core block has
been fully dimensionned.
::runGlobalrouter() contains the code tasked with the grid creation
and channel sizing.
* New: In KatanaEngine: Added support for core block, for 2-Metal routing.
May be expanded for over-the-cell routing in the future.
Added methods :
- isDigitalMode()
- isAnalogMode()
- isMixedMode()
- isChannelMode()
- getBlock() / addBlock()
- setupChannelMode()
- createChannel()
* New: In Katana, new class Block to manage core blocks and perform
channel routing.
* New: In Katana::Session, new convenience method "isOpen()".

::runGlobalrouter() contains the code tasked with the grid creation
and channel sizing.
* New: In KatanaEngine: Added support for core block, for 2-Metal routing.
May be expanded for over-the-cell routing in the future.
Added methods :
- isDigitalMode()
- isAnalogMode()
- isMixedMode()
- isChannelMode()
- getBlock() / addBlock()
- setupChannelMode()

Added support for 2-Metal block routing in Anabatic & Katana.
* New: In AnabaticEngine::invalidateRoutingPads() this method is a temporary
workaround for a Hurricane problems. When an instance is moved, the
RoutingPads that use it must be moved accordingly, but they are not
invalidated so they stay in the wrong QuadTree.
New method ::_resizeMatrix() to be called when the associated Cell
is resized.
* Bug: In AutoHorizontal::getConstraints() and AutoVertical::getConstraints(),
the *target* constraints where never merged.
* Change: In AutoHorizontal::getCells() and AutoVertical::getGCells(),
now return a boolean to tell if it was ok (must not encounter a NULL
GCell while progessing from source to target).
* New: In Anabatic::Configuration and Anabatic:Session, create new methods:
- getDHorizontalLayer()
- getDhorizontalDepth()
- getDHorizontalWidth()
- getDHorizontalPitch()
And so on for Vertical and Contact.
They supply depth-independant informations about the H/V layers to
build the initial detailed routing.
The AutoSegment::create() methods have been modificated accordingly.
* New: In Anabatic::GCell, add two new types "StdCellRow" and "ChannelRow"
for implementing 2-Metal blocks.
Rename the GCell::setXY() method in GCell::setSouthWestCorner(),
move the contents of GCell::updateContactsPosition() into it and
suppress it.
WARNING: In case of a GCell shrink this may cause problems. But for
now we only expand...
New method GCell::getNetCount() to count the number of Net going
though the GCell.
* Change: In Anabatic::Edge, add specific support for capacity of 2-Metal
routing channels.
* Change: In Anabatic::Dijsktra various methods, replace the "gcell->isMatrix()"
calls by "not gcell->isAnalog()". Add more check so that the methods
pertaining to the analog routing (GRData) are not called in digital
mode.
* New: In Anabatic::Dijkstra::materialize(), add support for 2-Metal specific
cases. That is, always break in case of vertical pass-through or
U-turn. The global routing must always be broken in H-Channel.
* New: In Anabatic::GCell & Anabatic::Edge, make use of the Session mechanism
to ensure the revalidation. The "::revalidate()" method is then moved
as "::materialize()" (overload of Go) and "::_invalidate()" becomes
"::invalidate()"
* Change: In LoadGlobalRouting, cosmetic rename of SortHkByX in SortHookByX.
* New: In GCellTopology, added support for building 2-Metal topologies.
* ForkStack is now an object attribute as many methods do need it.
* To push segments/hook on the stack, a new method "push()" is
available. Perform NULL and fromHook checking. Can also setup
_southWestContact or _northEastContact if it is the "from" edge.
* N/S/E/W edges are now vector as in digital channel mode there
can be more than one.
* Added build topological build methods:
- doRp_2m_Access() RoutingPad stem access.
- _do_2m_1G_1M1() North or south access.
- _do_2m_2G_1M1() North AND south access.
- _do_2m_xG() H-Channel routing.
* New: In Anabatic::Matrix, new ::resize() function, as Cell can be resizeds.
* New: In Anabatic::Vertex, new static method ::getValueString() for a
friendly text rendering.
* New: In Katana::DigitalDistance, support for channel routing.
* Change: In KatanaEngine::digitalSetup() and KatanaEngine::runGlobalrouter(),
for channel routing, calls to setupPowerRails() and
protectRoutingPads() must be called after the core block has
been fully dimensionned.
::runGlobalrouter() contains the code tasked with the grid creation

Support for mixing real pads & symbolic core. Wrapper around s2r.
* 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...

In Anabatic/Katana, add support for VH gauges (real technos).
* Change: In Anabatic::AutoContactTerminal::getNativeConstraintBox(),
when the anchor is a RoutingPad (which must be always the case),
perform the true computation of it's position based on the
segment occurrence. It is a important change, previously the
area was in fact the "center line" of the connector while now
it is really an area (mandatory for "half-offgrid" terminals of
real technologies).
The change is not complete yet, the area should be shrinked
by the half size of a VIA, because the area applies to the center
coordinate of the VIA (to be done quickly).
* Bug: In Anabatic::AutoContactTurn::updateTopology(), when a dogleg
is created (restore connexity after a layer change) the layer of
the VIA, based on the segments it connects to must be re-computed
*after* the dogleg has been made.
* Change: In all files of Anabatic, when comparing two layers, no longer
use the Layer pointer itself, but the layer mask. This allow a
transparent management of both real and symbolic layers (which
do share the same mask). Real metal layers (not VIAs) will be
BasicLayer and symbolic metal layers will be RegularLayer.
* New: Anabatic::Configuration::selectRpComponent(), select the best
RoutingPad component for metal1 terminals. Look for the metal1
component with the biggest accessibility on-grid.
RoutingPad using other metals are left untoucheds.
* New: New function Anabatic::Vertex::getNeighbor(Edge*) to get the
neighbor Vertex through an Edge*. This method allows to write
clearer code as we no longer need to access the neighbor through
the underlying GCell.
Also add proxies for GCell methods in Vertex.
* Bug: In Anabatic::Dijkstra::_toSources(), in the ripup stage, when
a component with multiples vertexes is reached *and* two of it's
vertexes are reached *at the same time* (one from which we backtrack
and one still in the queue) extraneous edges may be created by
_materialize(). Case occurs on snx/c35b4, "abc_5360_n903_1".
To solve this, Dijkstra::_toSource() is modificated, the "from"
edges of the newly reacheds vertexes are reset to NULL, *except*
for the one we will be backtracking from. That is, the one given
in the source argument.
* Change: In Anabatic::NetBuilder class, put the various Hooks and
RoutingPad sorting functions as class ones.
* Bug: In AutoSegment::setLayer(), raise the SegInvalidatedFayer flag.
This unset flag was causing AutoContactTurn::updateTopology()
to not work as expected and making gaps, this was the cause of
the last remaining warnings about layer connexity.

Anabatic transient commit 18. Port of Kite (Katana), Yeah, Baby! Yeah!
* Bug: In Hurricane, in StaticObservable::getObserver(), if the slot
pointer is NULL, do not try to access the owner. Returns NULL, so
the caller can be aware of the situation...
* Change: In Hurricane, in BreakpointWidget & ExceptionWidget some
cosmetic changes (fonts and window sizes).
* Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account
the constraints from the source AutoContact, as it holds the constraints
transmitted by the RoutingPads and sets up by propageConstraintsFromRp().
It is likely to be a bug affecting the original Katabatic as well.
* Change: In Anabatic, in RawGCellsUnder(), check that the segment is not
completly oustside the cell abutment box and truncate the coordinates
to the part that is inside. Use the "shrink" if we reach the east/north
border.
* Change: In Anabatic, in Configuration, no more decorator because we will
use a true derived relationship. Katana *derives* from *Anabatic* and do
not *decorate* it, so the Configuration can do the same. It also implies
that we directly create a Katana engine, not an Anabatic one.
* Change: In Anabatic, in Session, do not allow the opening of the Session
in a standalone fashion (with a static method). Instead it must be opened
using the relevant method of the Anabatic/Katana engine. This ensure we
are opening the right Session type.
* Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment
is not part of the collection by default, but will be included if the
Flags::WithSelf is set.
* Change: In Configuration, all the flags value are now defined in two steps.
Declared in the header and initialized in the module. This is to prevent
the fact that on some cases, in relation with the Python "extern C" part
modules, we need a true allocated variable. It was causing weird linking
problems.
A side effect is that they can no longer be used as entry is switches,
have to replace them by if/else.
* New: In Anabatic, new GCell::getNeighborAt() utility function.
* Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with
the grid type... Back annote all the edges capacity (north & east) with
the reserved local capacity.
* New: Complete portage of Kite over Anabatic. The new engine is christened
"Katana" for Kite-Analogic. When it's capabilities and performances
will be on a part with Kite, it is to completly replace it (and take
back the "Kite" name). Preliminary tests seems to show that, contrary
to intuition (because built on a more complex/slower grid), it is even
slightly faster than Kite 8-).

Configuration::Configuration ( const Configuration& other )

Corrections in the Dijkstra global routing (ripup) mechanism.
* Bug: In Anabatic::Dijkstra, the degree of a vertex (the number of neighbors
belonging to the same net) was miscalculated. This was leading, in the
materialize step to some feed-through vertexes not being broken.
Leading in turn to incomplete transformation of the detailed routing.
Also in _trackback(), the degree of the first vertex we were backtracking
from was not incremented.
* Bug: In Anabatic::Dijkstra::materialize(), systematically use
GCell::breakGoThrough() on both source and target. This is needed when
we are in the ripup phase as both source and target can be go-through.
This was also leading to incomplete detailed routing transformation.
* Change: In Anabatic::Edge::ripup(), ripup one third of the segments instead
of thoses exeeding the global length threshold. This way we are sure to
desaturate an edge. Needs to be further calibrated.
* Change: In Aanabatic::GCell::breakGoThrough(), no longer return NULL.
Return existing gcontact if any. Break if it is a go-through and create
a new gcontact in last resort. Maybe rename this function.
* New: In Anabatic::Configuration, new parameters:
- anabatic.edgeHScaling, to adjust the length of the horizontal edges
relative to the vertical ones (this is a ratio).
- anabatic.globalIterations, set the maximum number of ripup passes
of the global router.
* New: In CRL/etc/*/kite.conf, added new parameters anabatic.edgeHScaling
and anabatic.globalIterations.
* New: In Katana::GlobalRoute::DigitalDistance, take into account the new
edgeHScaling factor. Must be used when the capacity of V-edges differs
greatly for H-edges (case of AMS 350nm c35b4 for instance).
* Bug: In Katana::GlobalRoute::DigitalDistance, the historic cost is
computed for an edge length of "1". Must be multiplicated by the
current edge length to have any measurable effect.
This bug is finally explaining why the ripup was producing the
same solutions over and over, the historical cost was negligible!

Anabatic transient commit 18. Port of Kite (Katana), Yeah, Baby! Yeah!
* Bug: In Hurricane, in StaticObservable::getObserver(), if the slot
pointer is NULL, do not try to access the owner. Returns NULL, so
the caller can be aware of the situation...
* Change: In Hurricane, in BreakpointWidget & ExceptionWidget some
cosmetic changes (fonts and window sizes).
* Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account
the constraints from the source AutoContact, as it holds the constraints
transmitted by the RoutingPads and sets up by propageConstraintsFromRp().
It is likely to be a bug affecting the original Katabatic as well.
* Change: In Anabatic, in RawGCellsUnder(), check that the segment is not
completly oustside the cell abutment box and truncate the coordinates
to the part that is inside. Use the "shrink" if we reach the east/north
border.
* Change: In Anabatic, in Configuration, no more decorator because we will
use a true derived relationship. Katana *derives* from *Anabatic* and do
not *decorate* it, so the Configuration can do the same. It also implies
that we directly create a Katana engine, not an Anabatic one.
* Change: In Anabatic, in Session, do not allow the opening of the Session
in a standalone fashion (with a static method). Instead it must be opened
using the relevant method of the Anabatic/Katana engine. This ensure we
are opening the right Session type.
* Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment
is not part of the collection by default, but will be included if the
Flags::WithSelf is set.
* Change: In Configuration, all the flags value are now defined in two steps.
Declared in the header and initialized in the module. This is to prevent
the fact that on some cases, in relation with the Python "extern C" part
modules, we need a true allocated variable. It was causing weird linking
problems.
A side effect is that they can no longer be used as entry is switches,
have to replace them by if/else.
* New: In Anabatic, new GCell::getNeighborAt() utility function.
* Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with
the grid type... Back annote all the edges capacity (north & east) with
the reserved local capacity.
* New: Complete portage of Kite over Anabatic. The new engine is christened
"Katana" for Kite-Analogic. When it's capabilities and performances
will be on a part with Kite, it is to completly replace it (and take
back the "Kite" name). Preliminary tests seems to show that, contrary
to intuition (because built on a more complex/slower grid), it is even
slightly faster than Kite 8-).

Corrections in the Dijkstra global routing (ripup) mechanism.
* Bug: In Anabatic::Dijkstra, the degree of a vertex (the number of neighbors
belonging to the same net) was miscalculated. This was leading, in the
materialize step to some feed-through vertexes not being broken.
Leading in turn to incomplete transformation of the detailed routing.
Also in _trackback(), the degree of the first vertex we were backtracking
from was not incremented.
* Bug: In Anabatic::Dijkstra::materialize(), systematically use
GCell::breakGoThrough() on both source and target. This is needed when
we are in the ripup phase as both source and target can be go-through.
This was also leading to incomplete detailed routing transformation.
* Change: In Anabatic::Edge::ripup(), ripup one third of the segments instead
of thoses exeeding the global length threshold. This way we are sure to
desaturate an edge. Needs to be further calibrated.
* Change: In Aanabatic::GCell::breakGoThrough(), no longer return NULL.
Return existing gcontact if any. Break if it is a go-through and create
a new gcontact in last resort. Maybe rename this function.
* New: In Anabatic::Configuration, new parameters:
- anabatic.edgeHScaling, to adjust the length of the horizontal edges
relative to the vertical ones (this is a ratio).
- anabatic.globalIterations, set the maximum number of ripup passes
of the global router.

Declared in the header and initialized in the module. This is to prevent
the fact that on some cases, in relation with the Python "extern C" part
modules, we need a true allocated variable. It was causing weird linking
problems.
A side effect is that they can no longer be used as entry is switches,
have to replace them by if/else.
* New: In Anabatic, new GCell::getNeighborAt() utility function.
* Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with
the grid type... Back annote all the edges capacity (north & east) with
the reserved local capacity.
* New: Complete portage of Kite over Anabatic. The new engine is christened
"Katana" for Kite-Analogic. When it's capabilities and performances
will be on a part with Kite, it is to completly replace it (and take
back the "Kite" name). Preliminary tests seems to show that, contrary
to intuition (because built on a more complex/slower grid), it is even
slightly faster than Kite 8-).

Corrections in the Dijkstra global routing (ripup) mechanism.
* Bug: In Anabatic::Dijkstra, the degree of a vertex (the number of neighbors
belonging to the same net) was miscalculated. This was leading, in the
materialize step to some feed-through vertexes not being broken.
Leading in turn to incomplete transformation of the detailed routing.
Also in _trackback(), the degree of the first vertex we were backtracking
from was not incremented.
* Bug: In Anabatic::Dijkstra::materialize(), systematically use
GCell::breakGoThrough() on both source and target. This is needed when
we are in the ripup phase as both source and target can be go-through.
This was also leading to incomplete detailed routing transformation.
* Change: In Anabatic::Edge::ripup(), ripup one third of the segments instead
of thoses exeeding the global length threshold. This way we are sure to
desaturate an edge. Needs to be further calibrated.
* Change: In Aanabatic::GCell::breakGoThrough(), no longer return NULL.
Return existing gcontact if any. Break if it is a go-through and create
a new gcontact in last resort. Maybe rename this function.
* New: In Anabatic::Configuration, new parameters:
- anabatic.edgeHScaling, to adjust the length of the horizontal edges
relative to the vertical ones (this is a ratio).
- anabatic.globalIterations, set the maximum number of ripup passes
of the global router.
* New: In CRL/etc/*/kite.conf, added new parameters anabatic.edgeHScaling
and anabatic.globalIterations.
* New: In Katana::GlobalRoute::DigitalDistance, take into account the new
edgeHScaling factor. Must be used when the capacity of V-edges differs
greatly for H-edges (case of AMS 350nm c35b4 for instance).
* Bug: In Katana::GlobalRoute::DigitalDistance, the historic cost is
computed for an edge length of "1". Must be multiplicated by the
current edge length to have any measurable effect.
This bug is finally explaining why the ripup was producing the
same solutions over and over, the historical cost was negligible!

Anabatic transient commit 18. Port of Kite (Katana), Yeah, Baby! Yeah!
* Bug: In Hurricane, in StaticObservable::getObserver(), if the slot
pointer is NULL, do not try to access the owner. Returns NULL, so
the caller can be aware of the situation...
* Change: In Hurricane, in BreakpointWidget & ExceptionWidget some
cosmetic changes (fonts and window sizes).
* Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account
the constraints from the source AutoContact, as it holds the constraints
transmitted by the RoutingPads and sets up by propageConstraintsFromRp().
It is likely to be a bug affecting the original Katabatic as well.
* Change: In Anabatic, in RawGCellsUnder(), check that the segment is not
completly oustside the cell abutment box and truncate the coordinates
to the part that is inside. Use the "shrink" if we reach the east/north
border.
* Change: In Anabatic, in Configuration, no more decorator because we will
use a true derived relationship. Katana *derives* from *Anabatic* and do
not *decorate* it, so the Configuration can do the same. It also implies
that we directly create a Katana engine, not an Anabatic one.
* Change: In Anabatic, in Session, do not allow the opening of the Session
in a standalone fashion (with a static method). Instead it must be opened
using the relevant method of the Anabatic/Katana engine. This ensure we
are opening the right Session type.
* Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment
is not part of the collection by default, but will be included if the
Flags::WithSelf is set.
* Change: In Configuration, all the flags value are now defined in two steps.

border.
* Change: In Anabatic, in Configuration, no more decorator because we will
use a true derived relationship. Katana *derives* from *Anabatic* and do
not *decorate* it, so the Configuration can do the same. It also implies
that we directly create a Katana engine, not an Anabatic one.
* Change: In Anabatic, in Session, do not allow the opening of the Session
in a standalone fashion (with a static method). Instead it must be opened
using the relevant method of the Anabatic/Katana engine. This ensure we
are opening the right Session type.
* Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment
is not part of the collection by default, but will be included if the
Flags::WithSelf is set.
* Change: In Configuration, all the flags value are now defined in two steps.
Declared in the header and initialized in the module. This is to prevent
the fact that on some cases, in relation with the Python "extern C" part
modules, we need a true allocated variable. It was causing weird linking
problems.
A side effect is that they can no longer be used as entry is switches,
have to replace them by if/else.
* New: In Anabatic, new GCell::getNeighborAt() utility function.
* Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with
the grid type... Back annote all the edges capacity (north & east) with
the reserved local capacity.
* New: Complete portage of Kite over Anabatic. The new engine is christened
"Katana" for Kite-Analogic. When it's capabilities and performances
will be on a part with Kite, it is to completly replace it (and take
back the "Kite" name). Preliminary tests seems to show that, contrary
to intuition (because built on a more complex/slower grid), it is even
slightly faster than Kite 8-).

Anabatic transient commit 18. Port of Kite (Katana), Yeah, Baby! Yeah!
* Bug: In Hurricane, in StaticObservable::getObserver(), if the slot
pointer is NULL, do not try to access the owner. Returns NULL, so
the caller can be aware of the situation...
* Change: In Hurricane, in BreakpointWidget & ExceptionWidget some
cosmetic changes (fonts and window sizes).
* Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account
the constraints from the source AutoContact, as it holds the constraints
transmitted by the RoutingPads and sets up by propageConstraintsFromRp().
It is likely to be a bug affecting the original Katabatic as well.

completly oustside the cell abutment box and truncate the coordinates

Anabatic transient commit 18. Port of Kite (Katana), Yeah, Baby! Yeah!
* Bug: In Hurricane, in StaticObservable::getObserver(), if the slot
pointer is NULL, do not try to access the owner. Returns NULL, so
the caller can be aware of the situation...
* Change: In Hurricane, in BreakpointWidget & ExceptionWidget some
cosmetic changes (fonts and window sizes).
* Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account
the constraints from the source AutoContact, as it holds the constraints
transmitted by the RoutingPads and sets up by propageConstraintsFromRp().
It is likely to be a bug affecting the original Katabatic as well.
* Change: In Anabatic, in RawGCellsUnder(), check that the segment is not
completly oustside the cell abutment box and truncate the coordinates
to the part that is inside. Use the "shrink" if we reach the east/north
border.
* Change: In Anabatic, in Configuration, no more decorator because we will
use a true derived relationship. Katana *derives* from *Anabatic* and do
not *decorate* it, so the Configuration can do the same. It also implies
that we directly create a Katana engine, not an Anabatic one.
* Change: In Anabatic, in Session, do not allow the opening of the Session
in a standalone fashion (with a static method). Instead it must be opened
using the relevant method of the Anabatic/Katana engine. This ensure we
are opening the right Session type.
* Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment
is not part of the collection by default, but will be included if the
Flags::WithSelf is set.
* Change: In Configuration, all the flags value are now defined in two steps.
Declared in the header and initialized in the module. This is to prevent
the fact that on some cases, in relation with the Python "extern C" part
modules, we need a true allocated variable. It was causing weird linking
problems.
A side effect is that they can no longer be used as entry is switches,
have to replace them by if/else.
* New: In Anabatic, new GCell::getNeighborAt() utility function.
* Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with
the grid type... Back annote all the edges capacity (north & east) with
the reserved local capacity.
* New: Complete portage of Kite over Anabatic. The new engine is christened
"Katana" for Kite-Analogic. When it's capabilities and performances
will be on a part with Kite, it is to completly replace it (and take
back the "Kite" name). Preliminary tests seems to show that, contrary
to intuition (because built on a more complex/slower grid), it is even
slightly faster than Kite 8-).

Anabatic transient commit 18. Port of Kite (Katana), Yeah, Baby! Yeah!
* Bug: In Hurricane, in StaticObservable::getObserver(), if the slot
pointer is NULL, do not try to access the owner. Returns NULL, so
the caller can be aware of the situation...
* Change: In Hurricane, in BreakpointWidget & ExceptionWidget some
cosmetic changes (fonts and window sizes).
* Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account
the constraints from the source AutoContact, as it holds the constraints
transmitted by the RoutingPads and sets up by propageConstraintsFromRp().
It is likely to be a bug affecting the original Katabatic as well.
* Change: In Anabatic, in RawGCellsUnder(), check that the segment is not
completly oustside the cell abutment box and truncate the coordinates
to the part that is inside. Use the "shrink" if we reach the east/north
border.
* Change: In Anabatic, in Configuration, no more decorator because we will
use a true derived relationship. Katana *derives* from *Anabatic* and do
not *decorate* it, so the Configuration can do the same. It also implies
that we directly create a Katana engine, not an Anabatic one.
* Change: In Anabatic, in Session, do not allow the opening of the Session
in a standalone fashion (with a static method). Instead it must be opened
using the relevant method of the Anabatic/Katana engine. This ensure we
are opening the right Session type.
* Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment
is not part of the collection by default, but will be included if the
Flags::WithSelf is set.
* Change: In Configuration, all the flags value are now defined in two steps.
Declared in the header and initialized in the module. This is to prevent
the fact that on some cases, in relation with the Python "extern C" part
modules, we need a true allocated variable. It was causing weird linking
problems.
A side effect is that they can no longer be used as entry is switches,
have to replace them by if/else.
* New: In Anabatic, new GCell::getNeighborAt() utility function.
* Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with
the grid type... Back annote all the edges capacity (north & east) with
the reserved local capacity.
* New: Complete portage of Kite over Anabatic. The new engine is christened
"Katana" for Kite-Analogic. When it's capabilities and performances
will be on a part with Kite, it is to completly replace it (and take
back the "Kite" name). Preliminary tests seems to show that, contrary
to intuition (because built on a more complex/slower grid), it is even
slightly faster than Kite 8-).

cerr << Error( "In Configuration::Concrete::_setTopRoutingLayer():\n"

Added support for 2-Metal block routing in Anabatic & Katana.
* New: In AnabaticEngine::invalidateRoutingPads() this method is a temporary
workaround for a Hurricane problems. When an instance is moved, the
RoutingPads that use it must be moved accordingly, but they are not
invalidated so they stay in the wrong QuadTree.
New method ::_resizeMatrix() to be called when the associated Cell
is resized.
* Bug: In AutoHorizontal::getConstraints() and AutoVertical::getConstraints(),
the *target* constraints where never merged.
* Change: In AutoHorizontal::getCells() and AutoVertical::getGCells(),
now return a boolean to tell if it was ok (must not encounter a NULL
GCell while progessing from source to target).
* New: In Anabatic::Configuration and Anabatic:Session, create new methods:
- getDHorizontalLayer()
- getDhorizontalDepth()
- getDHorizontalWidth()
- getDHorizontalPitch()
And so on for Vertical and Contact.
They supply depth-independant informations about the H/V layers to
build the initial detailed routing.
The AutoSegment::create() methods have been modificated accordingly.
* New: In Anabatic::GCell, add two new types "StdCellRow" and "ChannelRow"
for implementing 2-Metal blocks.
Rename the GCell::setXY() method in GCell::setSouthWestCorner(),
move the contents of GCell::updateContactsPosition() into it and
suppress it.
WARNING: In case of a GCell shrink this may cause problems. But for
now we only expand...
New method GCell::getNetCount() to count the number of Net going
though the GCell.
* Change: In Anabatic::Edge, add specific support for capacity of 2-Metal
routing channels.
* Change: In Anabatic::Dijsktra various methods, replace the "gcell->isMatrix()"
calls by "not gcell->isAnalog()". Add more check so that the methods
pertaining to the analog routing (GRData) are not called in digital
mode.
* New: In Anabatic::Dijkstra::materialize(), add support for 2-Metal specific
cases. That is, always break in case of vertical pass-through or
U-turn. The global routing must always be broken in H-Channel.
* New: In Anabatic::GCell & Anabatic::Edge, make use of the Session mechanism
to ensure the revalidation. The "::revalidate()" method is then moved
as "::materialize()" (overload of Go) and "::_invalidate()" becomes
"::invalidate()"
* Change: In LoadGlobalRouting, cosmetic rename of SortHkByX in SortHookByX.
* New: In GCellTopology, added support for building 2-Metal topologies.
* ForkStack is now an object attribute as many methods do need it.
* To push segments/hook on the stack, a new method "push()" is
available. Perform NULL and fromHook checking. Can also setup
_southWestContact or _northEastContact if it is the "from" edge.
* N/S/E/W edges are now vector as in digital channel mode there
can be more than one.
* Added build topological build methods:
- doRp_2m_Access() RoutingPad stem access.
- _do_2m_1G_1M1() North or south access.
- _do_2m_2G_1M1() North AND south access.
- _do_2m_xG() H-Channel routing.
* New: In Anabatic::Matrix, new ::resize() function, as Cell can be resizeds.
* New: In Anabatic::Vertex, new static method ::getValueString() for a
friendly text rendering.
* New: In Katana::DigitalDistance, support for channel routing.
* Change: In KatanaEngine::digitalSetup() and KatanaEngine::runGlobalrouter(),
for channel routing, calls to setupPowerRails() and
protectRoutingPads() must be called after the core block has
been fully dimensionned.
::runGlobalrouter() contains the code tasked with the grid creation
and channel sizing.
* New: In KatanaEngine: Added support for core block, for 2-Metal routing.
May be expanded for over-the-cell routing in the future.
Added methods :
- isDigitalMode()
- isAnalogMode()
- isMixedMode()
- isChannelMode()
- getBlock() / addBlock()
- setupChannelMode()
- createChannel()
* New: In Katana, new class Block to manage core blocks and perform
channel routing.
* New: In Katana::Session, new convenience method "isOpen()".

Anabatic transient commit 18. Port of Kite (Katana), Yeah, Baby! Yeah!
* Bug: In Hurricane, in StaticObservable::getObserver(), if the slot
pointer is NULL, do not try to access the owner. Returns NULL, so
the caller can be aware of the situation...
* Change: In Hurricane, in BreakpointWidget & ExceptionWidget some
cosmetic changes (fonts and window sizes).
* Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account
the constraints from the source AutoContact, as it holds the constraints
transmitted by the RoutingPads and sets up by propageConstraintsFromRp().
It is likely to be a bug affecting the original Katabatic as well.
* Change: In Anabatic, in RawGCellsUnder(), check that the segment is not
completly oustside the cell abutment box and truncate the coordinates
to the part that is inside. Use the "shrink" if we reach the east/north
border.
* Change: In Anabatic, in Configuration, no more decorator because we will
use a true derived relationship. Katana *derives* from *Anabatic* and do
not *decorate* it, so the Configuration can do the same. It also implies
that we directly create a Katana engine, not an Anabatic one.
* Change: In Anabatic, in Session, do not allow the opening of the Session
in a standalone fashion (with a static method). Instead it must be opened
using the relevant method of the Anabatic/Katana engine. This ensure we
are opening the right Session type.
* Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment
is not part of the collection by default, but will be included if the
Flags::WithSelf is set.
* Change: In Configuration, all the flags value are now defined in two steps.
Declared in the header and initialized in the module. This is to prevent
the fact that on some cases, in relation with the Python "extern C" part
modules, we need a true allocated variable. It was causing weird linking
problems.
A side effect is that they can no longer be used as entry is switches,
have to replace them by if/else.
* New: In Anabatic, new GCell::getNeighborAt() utility function.
* Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with
the grid type... Back annote all the edges capacity (north & east) with
the reserved local capacity.
* New: Complete portage of Kite over Anabatic. The new engine is christened
"Katana" for Kite-Analogic. When it's capabilities and performances
will be on a part with Kite, it is to completly replace it (and take
back the "Kite" name). Preliminary tests seems to show that, contrary
to intuition (because built on a more complex/slower grid), it is even
slightly faster than Kite 8-).

Anabatic transient commit 18. Port of Kite (Katana), Yeah, Baby! Yeah!
* Bug: In Hurricane, in StaticObservable::getObserver(), if the slot
pointer is NULL, do not try to access the owner. Returns NULL, so
the caller can be aware of the situation...
* Change: In Hurricane, in BreakpointWidget & ExceptionWidget some
cosmetic changes (fonts and window sizes).
* Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account
the constraints from the source AutoContact, as it holds the constraints
transmitted by the RoutingPads and sets up by propageConstraintsFromRp().
It is likely to be a bug affecting the original Katabatic as well.
* Change: In Anabatic, in RawGCellsUnder(), check that the segment is not
completly oustside the cell abutment box and truncate the coordinates
to the part that is inside. Use the "shrink" if we reach the east/north
border.
* Change: In Anabatic, in Configuration, no more decorator because we will
use a true derived relationship. Katana *derives* from *Anabatic* and do
not *decorate* it, so the Configuration can do the same. It also implies
that we directly create a Katana engine, not an Anabatic one.
* Change: In Anabatic, in Session, do not allow the opening of the Session
in a standalone fashion (with a static method). Instead it must be opened
using the relevant method of the Anabatic/Katana engine. This ensure we
are opening the right Session type.
* Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment
is not part of the collection by default, but will be included if the
Flags::WithSelf is set.
* Change: In Configuration, all the flags value are now defined in two steps.
Declared in the header and initialized in the module. This is to prevent
the fact that on some cases, in relation with the Python "extern C" part
modules, we need a true allocated variable. It was causing weird linking
problems.
A side effect is that they can no longer be used as entry is switches,
have to replace them by if/else.
* New: In Anabatic, new GCell::getNeighborAt() utility function.
* Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with
the grid type... Back annote all the edges capacity (north & east) with
the reserved local capacity.
* New: Complete portage of Kite over Anabatic. The new engine is christened
"Katana" for Kite-Analogic. When it's capabilities and performances
will be on a part with Kite, it is to completly replace it (and take
back the "Kite" name). Preliminary tests seems to show that, contrary
to intuition (because built on a more complex/slower grid), it is even
slightly faster than Kite 8-).

Corrections in the Dijkstra global routing (ripup) mechanism.
* Bug: In Anabatic::Dijkstra, the degree of a vertex (the number of neighbors
belonging to the same net) was miscalculated. This was leading, in the
materialize step to some feed-through vertexes not being broken.
Leading in turn to incomplete transformation of the detailed routing.
Also in _trackback(), the degree of the first vertex we were backtracking
from was not incremented.
* Bug: In Anabatic::Dijkstra::materialize(), systematically use
GCell::breakGoThrough() on both source and target. This is needed when
we are in the ripup phase as both source and target can be go-through.
This was also leading to incomplete detailed routing transformation.
* Change: In Anabatic::Edge::ripup(), ripup one third of the segments instead
of thoses exeeding the global length threshold. This way we are sure to
desaturate an edge. Needs to be further calibrated.
* Change: In Aanabatic::GCell::breakGoThrough(), no longer return NULL.
Return existing gcontact if any. Break if it is a go-through and create
a new gcontact in last resort. Maybe rename this function.
* New: In Anabatic::Configuration, new parameters:
- anabatic.edgeHScaling, to adjust the length of the horizontal edges
relative to the vertical ones (this is a ratio).
- anabatic.globalIterations, set the maximum number of ripup passes
of the global router.
* New: In CRL/etc/*/kite.conf, added new parameters anabatic.edgeHScaling
and anabatic.globalIterations.
* New: In Katana::GlobalRoute::DigitalDistance, take into account the new
edgeHScaling factor. Must be used when the capacity of V-edges differs
greatly for H-edges (case of AMS 350nm c35b4 for instance).
* Bug: In Katana::GlobalRoute::DigitalDistance, the historic cost is
computed for an edge length of "1". Must be multiplicated by the
current edge length to have any measurable effect.
This bug is finally explaining why the ripup was producing the
same solutions over and over, the historical cost was negligible!

In Anabatic/Katana, add support for VH gauges (real technos).
* Change: In Anabatic::AutoContactTerminal::getNativeConstraintBox(),
when the anchor is a RoutingPad (which must be always the case),
perform the true computation of it's position based on the
segment occurrence. It is a important change, previously the
area was in fact the "center line" of the connector while now
it is really an area (mandatory for "half-offgrid" terminals of
real technologies).
The change is not complete yet, the area should be shrinked
by the half size of a VIA, because the area applies to the center
coordinate of the VIA (to be done quickly).
* Bug: In Anabatic::AutoContactTurn::updateTopology(), when a dogleg
is created (restore connexity after a layer change) the layer of
the VIA, based on the segments it connects to must be re-computed
*after* the dogleg has been made.
* Change: In all files of Anabatic, when comparing two layers, no longer
use the Layer pointer itself, but the layer mask. This allow a
transparent management of both real and symbolic layers (which
do share the same mask). Real metal layers (not VIAs) will be
BasicLayer and symbolic metal layers will be RegularLayer.
* New: Anabatic::Configuration::selectRpComponent(), select the best
RoutingPad component for metal1 terminals. Look for the metal1
component with the biggest accessibility on-grid.
RoutingPad using other metals are left untoucheds.
* New: New function Anabatic::Vertex::getNeighbor(Edge*) to get the
neighbor Vertex through an Edge*. This method allows to write
clearer code as we no longer need to access the neighbor through
the underlying GCell.
Also add proxies for GCell methods in Vertex.
* Bug: In Anabatic::Dijkstra::_toSources(), in the ripup stage, when
a component with multiples vertexes is reached *and* two of it's
vertexes are reached *at the same time* (one from which we backtrack
and one still in the queue) extraneous edges may be created by
_materialize(). Case occurs on snx/c35b4, "abc_5360_n903_1".
To solve this, Dijkstra::_toSource() is modificated, the "from"
edges of the newly reacheds vertexes are reset to NULL, *except*
for the one we will be backtracking from. That is, the one given
in the source argument.
* Change: In Anabatic::NetBuilder class, put the various Hooks and
RoutingPad sorting functions as class ones.
* Bug: In AutoSegment::setLayer(), raise the SegInvalidatedFayer flag.
This unset flag was causing AutoContactTurn::updateTopology()
to not work as expected and making gaps, this was the cause of
the last remaining warnings about layer connexity.

Basic support for FreePDK 45 completed.
* 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.

In Anabatic/Katana, add support for VH gauges (real technos).
* Change: In Anabatic::AutoContactTerminal::getNativeConstraintBox(),
when the anchor is a RoutingPad (which must be always the case),
perform the true computation of it's position based on the
segment occurrence. It is a important change, previously the
area was in fact the "center line" of the connector while now
it is really an area (mandatory for "half-offgrid" terminals of
real technologies).
The change is not complete yet, the area should be shrinked
by the half size of a VIA, because the area applies to the center
coordinate of the VIA (to be done quickly).
* Bug: In Anabatic::AutoContactTurn::updateTopology(), when a dogleg
is created (restore connexity after a layer change) the layer of
the VIA, based on the segments it connects to must be re-computed
*after* the dogleg has been made.
* Change: In all files of Anabatic, when comparing two layers, no longer
use the Layer pointer itself, but the layer mask. This allow a
transparent management of both real and symbolic layers (which
do share the same mask). Real metal layers (not VIAs) will be
BasicLayer and symbolic metal layers will be RegularLayer.
* New: Anabatic::Configuration::selectRpComponent(), select the best
RoutingPad component for metal1 terminals. Look for the metal1
component with the biggest accessibility on-grid.
RoutingPad using other metals are left untoucheds.
* New: New function Anabatic::Vertex::getNeighbor(Edge*) to get the
neighbor Vertex through an Edge*. This method allows to write
clearer code as we no longer need to access the neighbor through
the underlying GCell.
Also add proxies for GCell methods in Vertex.
* Bug: In Anabatic::Dijkstra::_toSources(), in the ripup stage, when
a component with multiples vertexes is reached *and* two of it's
vertexes are reached *at the same time* (one from which we backtrack
and one still in the queue) extraneous edges may be created by
_materialize(). Case occurs on snx/c35b4, "abc_5360_n903_1".

First working recursive place & route (Libre-SOC ALU16 benchmark).
* New: In Hurricane::Cell::isLeaf(), a leaf cell was defined as one
without instances. Now it can be software defined with the
"FlattenLeaf" state. If it is flagged "flatten leaf" is will be
considered as a leaf by the trans-hierarchical walkthrough.
This flag is also set for Cells in the Alliance CATAL.
* New: In Hurricane::Cell_LeafInstanceOccurrences::progress(), add a
test to prune leaf cells.
* Bug: In Hurricane::getComponentOccurrences(), when calling the
locator constructor, the "withLeafCells" argument was forgotten
and was getting the value of "doExtraction" (wich, fortunately,
was the same).
* Change: In Hurricane::HypreNet_LeafPlugOccurrences::progress(),
prune the leaf cells instead of the terminal ones.
* Change: In Hurricane::HypreNet_ComponentOccurrences::progress(),
prune the leaf cells instead of the terminal ones.
* New: In Hurricane::Cell, add a "useFlattenLeaf" mode to take into
account or ignore the "FlattenLeaf" flag when doing trans-
hierarchical walkthrough.
Not sure if it shouldn't be systematic.
* New: In Etesian::toColoquinte() and other, activate the "FlattenLeaf"
mode for all walkthough. So we can stop at already placed sub-blocks.
* Bug: In Etesian::toColoquinte(), when placed sub-block where present,
the number of instances was under estimated, so the instance array
was oversized and the end went unitialized. So we were getting all
kind of strange behavior from Coloquinte...
Now throw an exception if the number of instances differs from
the computed size.
* Bug: In Etesian::toColoquinte(), as for the instance array, now
correctly compute the size with the ecluded nets (supplies, clocks).
* Bug: In Etesian::resetPlacement(), event if the Cell is unplaced,
go through the instance list to remove the potential feed cells.
The netlist is written back after placement *with* the feed
cells added. So, when loading again, they where cluttering the
netlist and giving feed redefintions warning. They also generated
erratic behaviors.
* New: In Anabatic::NetBuilderHV, added configurations for:
* 1G_1M1_1PinM3
* 1G_xM1_1PinM2
* 2G_xM1_1PinM2
* doRp_AccessNorthPin
* New: In Anabatic::NetBuilderHV, added Pin management in SingleGCell.
* Bug: In Anabatic::NetBuilderHV::_do_xG_1PinM3(), the North/South
global routing configuration was forgotten (only East/West).
* Bug: In Katana::TrackFixedSegment, the blockage net was a static
variable initialized at the first run. So we were getting stuck
with the blockage net of the first cell to be routed. Of course,
it did show only when Katana was run multiple times in the same

Basic support for FreePDK 45 completed.
* 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

Upgrade of Katana detailed router to support Arlet 6502.
* 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).

Basic support for FreePDK 45 completed.
* 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.

In Anabatic/Katana, add support for VH gauges (real technos).
* Change: In Anabatic::AutoContactTerminal::getNativeConstraintBox(),
when the anchor is a RoutingPad (which must be always the case),
perform the true computation of it's position based on the
segment occurrence. It is a important change, previously the
area was in fact the "center line" of the connector while now
it is really an area (mandatory for "half-offgrid" terminals of
real technologies).
The change is not complete yet, the area should be shrinked
by the half size of a VIA, because the area applies to the center
coordinate of the VIA (to be done quickly).
* Bug: In Anabatic::AutoContactTurn::updateTopology(), when a dogleg
is created (restore connexity after a layer change) the layer of
the VIA, based on the segments it connects to must be re-computed
*after* the dogleg has been made.
* Change: In all files of Anabatic, when comparing two layers, no longer
use the Layer pointer itself, but the layer mask. This allow a
transparent management of both real and symbolic layers (which
do share the same mask). Real metal layers (not VIAs) will be
BasicLayer and symbolic metal layers will be RegularLayer.
* New: Anabatic::Configuration::selectRpComponent(), select the best
RoutingPad component for metal1 terminals. Look for the metal1
component with the biggest accessibility on-grid.
RoutingPad using other metals are left untoucheds.
* New: New function Anabatic::Vertex::getNeighbor(Edge*) to get the
neighbor Vertex through an Edge*. This method allows to write
clearer code as we no longer need to access the neighbor through
the underlying GCell.
Also add proxies for GCell methods in Vertex.
* Bug: In Anabatic::Dijkstra::_toSources(), in the ripup stage, when
a component with multiples vertexes is reached *and* two of it's
vertexes are reached *at the same time* (one from which we backtrack
and one still in the queue) extraneous edges may be created by
_materialize(). Case occurs on snx/c35b4, "abc_5360_n903_1".
To solve this, Dijkstra::_toSource() is modificated, the "from"
edges of the newly reacheds vertexes are reset to NULL, *except*
for the one we will be backtracking from. That is, the one given
in the source argument.
* Change: In Anabatic::NetBuilder class, put the various Hooks and
RoutingPad sorting functions as class ones.
* Bug: In AutoSegment::setLayer(), raise the SegInvalidatedFayer flag.
This unset flag was causing AutoContactTurn::updateTopology()
to not work as expected and making gaps, this was the cause of
the last remaining warnings about layer connexity.

Basic support for FreePDK 45 completed.
* 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.

In Anabatic/Katana, add support for VH gauges (real technos).
* Change: In Anabatic::AutoContactTerminal::getNativeConstraintBox(),
when the anchor is a RoutingPad (which must be always the case),
perform the true computation of it's position based on the
segment occurrence. It is a important change, previously the
area was in fact the "center line" of the connector while now
it is really an area (mandatory for "half-offgrid" terminals of
real technologies).
The change is not complete yet, the area should be shrinked
by the half size of a VIA, because the area applies to the center
coordinate of the VIA (to be done quickly).
* Bug: In Anabatic::AutoContactTurn::updateTopology(), when a dogleg
is created (restore connexity after a layer change) the layer of
the VIA, based on the segments it connects to must be re-computed
*after* the dogleg has been made.
* Change: In all files of Anabatic, when comparing two layers, no longer
use the Layer pointer itself, but the layer mask. This allow a
transparent management of both real and symbolic layers (which
do share the same mask). Real metal layers (not VIAs) will be
BasicLayer and symbolic metal layers will be RegularLayer.
* New: Anabatic::Configuration::selectRpComponent(), select the best
RoutingPad component for metal1 terminals. Look for the metal1
component with the biggest accessibility on-grid.
RoutingPad using other metals are left untoucheds.
* New: New function Anabatic::Vertex::getNeighbor(Edge*) to get the
neighbor Vertex through an Edge*. This method allows to write
clearer code as we no longer need to access the neighbor through
the underlying GCell.
Also add proxies for GCell methods in Vertex.
* Bug: In Anabatic::Dijkstra::_toSources(), in the ripup stage, when
a component with multiples vertexes is reached *and* two of it's
vertexes are reached *at the same time* (one from which we backtrack
and one still in the queue) extraneous edges may be created by
_materialize(). Case occurs on snx/c35b4, "abc_5360_n903_1".
To solve this, Dijkstra::_toSource() is modificated, the "from"
edges of the newly reacheds vertexes are reset to NULL, *except*
for the one we will be backtracking from. That is, the one given
in the source argument.
* Change: In Anabatic::NetBuilder class, put the various Hooks and
RoutingPad sorting functions as class ones.
* Bug: In AutoSegment::setLayer(), raise the SegInvalidatedFayer flag.
This unset flag was causing AutoContactTurn::updateTopology()
to not work as expected and making gaps, this was the cause of
the last remaining warnings about layer connexity.

First working recursive place & route (Libre-SOC ALU16 benchmark).
* New: In Hurricane::Cell::isLeaf(), a leaf cell was defined as one
without instances. Now it can be software defined with the
"FlattenLeaf" state. If it is flagged "flatten leaf" is will be
considered as a leaf by the trans-hierarchical walkthrough.
This flag is also set for Cells in the Alliance CATAL.
* New: In Hurricane::Cell_LeafInstanceOccurrences::progress(), add a
test to prune leaf cells.
* Bug: In Hurricane::getComponentOccurrences(), when calling the
locator constructor, the "withLeafCells" argument was forgotten
and was getting the value of "doExtraction" (wich, fortunately,
was the same).
* Change: In Hurricane::HypreNet_LeafPlugOccurrences::progress(),
prune the leaf cells instead of the terminal ones.
* Change: In Hurricane::HypreNet_ComponentOccurrences::progress(),
prune the leaf cells instead of the terminal ones.
* New: In Hurricane::Cell, add a "useFlattenLeaf" mode to take into
account or ignore the "FlattenLeaf" flag when doing trans-
hierarchical walkthrough.
Not sure if it shouldn't be systematic.
* New: In Etesian::toColoquinte() and other, activate the "FlattenLeaf"
mode for all walkthough. So we can stop at already placed sub-blocks.
* Bug: In Etesian::toColoquinte(), when placed sub-block where present,
the number of instances was under estimated, so the instance array
was oversized and the end went unitialized. So we were getting all
kind of strange behavior from Coloquinte...
Now throw an exception if the number of instances differs from
the computed size.
* Bug: In Etesian::toColoquinte(), as for the instance array, now
correctly compute the size with the ecluded nets (supplies, clocks).
* Bug: In Etesian::resetPlacement(), event if the Cell is unplaced,
go through the instance list to remove the potential feed cells.
The netlist is written back after placement *with* the feed
cells added. So, when loading again, they where cluttering the
netlist and giving feed redefintions warning. They also generated
erratic behaviors.
* New: In Anabatic::NetBuilderHV, added configurations for:
* 1G_1M1_1PinM3
* 1G_xM1_1PinM2
* 2G_xM1_1PinM2
* doRp_AccessNorthPin
* New: In Anabatic::NetBuilderHV, added Pin management in SingleGCell.
* Bug: In Anabatic::NetBuilderHV::_do_xG_1PinM3(), the North/South
global routing configuration was forgotten (only East/West).
* Bug: In Katana::TrackFixedSegment, the blockage net was a static
variable initialized at the first run. So we were getting stuck
with the blockage net of the first cell to be routed. Of course,
it did show only when Katana was run multiple times in the same
process.

Upgrade of Katana detailed router to support Arlet 6502.
* 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).

is created (restore connexity after a layer change) the layer of
the VIA, based on the segments it connects to must be re-computed
*after* the dogleg has been made.
* Change: In all files of Anabatic, when comparing two layers, no longer
use the Layer pointer itself, but the layer mask. This allow a
transparent management of both real and symbolic layers (which
do share the same mask). Real metal layers (not VIAs) will be
BasicLayer and symbolic metal layers will be RegularLayer.
* New: Anabatic::Configuration::selectRpComponent(), select the best
RoutingPad component for metal1 terminals. Look for the metal1
component with the biggest accessibility on-grid.
RoutingPad using other metals are left untoucheds.
* New: New function Anabatic::Vertex::getNeighbor(Edge*) to get the
neighbor Vertex through an Edge*. This method allows to write
clearer code as we no longer need to access the neighbor through
the underlying GCell.
Also add proxies for GCell methods in Vertex.
* Bug: In Anabatic::Dijkstra::_toSources(), in the ripup stage, when
a component with multiples vertexes is reached *and* two of it's
vertexes are reached *at the same time* (one from which we backtrack
and one still in the queue) extraneous edges may be created by
_materialize(). Case occurs on snx/c35b4, "abc_5360_n903_1".
To solve this, Dijkstra::_toSource() is modificated, the "from"
edges of the newly reacheds vertexes are reset to NULL, *except*
for the one we will be backtracking from. That is, the one given
in the source argument.
* Change: In Anabatic::NetBuilder class, put the various Hooks and
RoutingPad sorting functions as class ones.
* Bug: In AutoSegment::setLayer(), raise the SegInvalidatedFayer flag.
This unset flag was causing AutoContactTurn::updateTopology()
to not work as expected and making gaps, this was the cause of
the last remaining warnings about layer connexity.

In Anabatic/Katana, add support for VH gauges (real technos).
* Change: In Anabatic::AutoContactTerminal::getNativeConstraintBox(),
when the anchor is a RoutingPad (which must be always the case),
perform the true computation of it's position based on the
segment occurrence. It is a important change, previously the
area was in fact the "center line" of the connector while now
it is really an area (mandatory for "half-offgrid" terminals of
real technologies).
The change is not complete yet, the area should be shrinked
by the half size of a VIA, because the area applies to the center
coordinate of the VIA (to be done quickly).
* Bug: In Anabatic::AutoContactTurn::updateTopology(), when a dogleg

the VIA, based on the segments it connects to must be re-computed

Anabatic transient commit 18. Port of Kite (Katana), Yeah, Baby! Yeah!
* Bug: In Hurricane, in StaticObservable::getObserver(), if the slot
pointer is NULL, do not try to access the owner. Returns NULL, so
the caller can be aware of the situation...
* Change: In Hurricane, in BreakpointWidget & ExceptionWidget some
cosmetic changes (fonts and window sizes).
* Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account
the constraints from the source AutoContact, as it holds the constraints
transmitted by the RoutingPads and sets up by propageConstraintsFromRp().
It is likely to be a bug affecting the original Katabatic as well.
* Change: In Anabatic, in RawGCellsUnder(), check that the segment is not
completly oustside the cell abutment box and truncate the coordinates
to the part that is inside. Use the "shrink" if we reach the east/north
border.
* Change: In Anabatic, in Configuration, no more decorator because we will
use a true derived relationship. Katana *derives* from *Anabatic* and do
not *decorate* it, so the Configuration can do the same. It also implies
that we directly create a Katana engine, not an Anabatic one.
* Change: In Anabatic, in Session, do not allow the opening of the Session
in a standalone fashion (with a static method). Instead it must be opened
using the relevant method of the Anabatic/Katana engine. This ensure we
are opening the right Session type.
* Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment
is not part of the collection by default, but will be included if the
Flags::WithSelf is set.
* Change: In Configuration, all the flags value are now defined in two steps.
Declared in the header and initialized in the module. This is to prevent
the fact that on some cases, in relation with the Python "extern C" part
modules, we need a true allocated variable. It was causing weird linking
problems.
A side effect is that they can no longer be used as entry is switches,
have to replace them by if/else.
* New: In Anabatic, new GCell::getNeighborAt() utility function.
* Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with
the grid type... Back annote all the edges capacity (north & east) with
the reserved local capacity.
* New: Complete portage of Kite over Anabatic. The new engine is christened
"Katana" for Kite-Analogic. When it's capabilities and performances
will be on a part with Kite, it is to completly replace it (and take
back the "Kite" name). Preliminary tests seems to show that, contrary
to intuition (because built on a more complex/slower grid), it is even
slightly faster than Kite 8-).

Groudwork for routing density driven placement. Compliance with clang 5.0.1.
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.

Added support for 2-Metal block routing in Anabatic & Katana.
* New: In AnabaticEngine::invalidateRoutingPads() this method is a temporary
workaround for a Hurricane problems. When an instance is moved, the
RoutingPads that use it must be moved accordingly, but they are not
invalidated so they stay in the wrong QuadTree.
New method ::_resizeMatrix() to be called when the associated Cell
is resized.
* Bug: In AutoHorizontal::getConstraints() and AutoVertical::getConstraints(),
the *target* constraints where never merged.
* Change: In AutoHorizontal::getCells() and AutoVertical::getGCells(),
now return a boolean to tell if it was ok (must not encounter a NULL
GCell while progessing from source to target).
* New: In Anabatic::Configuration and Anabatic:Session, create new methods:
- getDHorizontalLayer()
- getDhorizontalDepth()
- getDHorizontalWidth()
- getDHorizontalPitch()
And so on for Vertical and Contact.
They supply depth-independant informations about the H/V layers to
build the initial detailed routing.
The AutoSegment::create() methods have been modificated accordingly.
* New: In Anabatic::GCell, add two new types "StdCellRow" and "ChannelRow"
for implementing 2-Metal blocks.
Rename the GCell::setXY() method in GCell::setSouthWestCorner(),
move the contents of GCell::updateContactsPosition() into it and
suppress it.
WARNING: In case of a GCell shrink this may cause problems. But for
now we only expand...
New method GCell::getNetCount() to count the number of Net going
though the GCell.
* Change: In Anabatic::Edge, add specific support for capacity of 2-Metal
routing channels.
* Change: In Anabatic::Dijsktra various methods, replace the "gcell->isMatrix()"
calls by "not gcell->isAnalog()". Add more check so that the methods
pertaining to the analog routing (GRData) are not called in digital
mode.
* New: In Anabatic::Dijkstra::materialize(), add support for 2-Metal specific
cases. That is, always break in case of vertical pass-through or
U-turn. The global routing must always be broken in H-Channel.
* New: In Anabatic::GCell & Anabatic::Edge, make use of the Session mechanism
to ensure the revalidation. The "::revalidate()" method is then moved
as "::materialize()" (overload of Go) and "::_invalidate()" becomes
"::invalidate()"
* Change: In LoadGlobalRouting, cosmetic rename of SortHkByX in SortHookByX.
* New: In GCellTopology, added support for building 2-Metal topologies.
* ForkStack is now an object attribute as many methods do need it.
* To push segments/hook on the stack, a new method "push()" is
available. Perform NULL and fromHook checking. Can also setup
_southWestContact or _northEastContact if it is the "from" edge.
* N/S/E/W edges are now vector as in digital channel mode there
can be more than one.
* Added build topological build methods:
- doRp_2m_Access() RoutingPad stem access.
- _do_2m_1G_1M1() North or south access.
