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.

Replace "unsigned int" by "Flags" in all AutoSegments collections.
* Change: In Anabatic::AutoSegments collections, change the type of all
the flags that where in "unsigned int" (32 bits) to Flags (uint64_t)
as there is now more than 32 flags for functions.
* New: In Ababatic::Constants, added new flag Flags::WithPerpands, which
makes the number of flags tip over 32 bits, thus making mandatory
to uses Flags and not unsigned int.
* New: In Anabatic::AutoSegments_Perpandiculars, manage a new flag
Flags::WithDoglegs to allow to propagate through global segments that
are connecteds via doglegs on local segments. Meaning that there is
a good chance that they could be aligned.
Slighly change the way we propagate on aligned segments: no longer
check for VTee or HTee, but only for same direction and layer as
master.
* New: In Anabatic & Katana, replace all the "int", "long" and their
variants by the less implementation ambiguous "int32_t", "int64_t"
(and variant). This should help to better detect bit trucation in
flags.
Use the type to give a hint about the flags kind:
- Type "Flags", for flags shared among Anabatic & Katana
functions/methods (may also appear in some objects states).
- Type "uint32_t" for flags belonging to an object internal
state of from Hurricane functions flags (those should be
grouped in a Flag subclass in a perfect world).

Improved management of AutoContactTerminal for VH gauges (real ones).
* New: In Anabatic & Katana, add the new "drag" feature.
With VH gauges used by real technologies (M1-H, M2-V, M3-H) a new
routing configuration that was not efficiently handled did appear.
While the preferred routing direction for metal1 is officially
horizontal, due to the way the standard cell must be designed,
their metal1 terminals are still verticals (or punctuals).
Thus, when connecting to them, we face the case where the metal1
terminal (RoutingPad) is vertical *and* the metal2 wire is also
vertical. With that setup, the position of the AutoContactTerminal
via12 cannot be deduced, it may range all the way over the
metal1 RoutingPad. What may define it's position is the metal3 the
metal2 finally connects to. That, is, when we have one horizontal
(the metal3) and one vertical (the metal1 RoutingPad).
The intermediate wire of metal2 can be kept to a minimum size
by "dragging" the via12 close to the via23 when the metal3 wire is
moved.
* New: In Anabatic & Katana, problem of closely vertically aligneds
RoutingPads in metal1 is managed first in PreProcess by restricting
the span of the connecteds metal3 and in _makeDogleg also by restricting
the span even more tightly (to the RoutingPad itself).
* New: In Anabatic::AutoContactTerminal, add the "drag" support.
Automatically check if the connecting segment is in the same
direction as the RoutingPad, if so, sets the "SegDrag" flag.
The dragging state can be known with the "::canDrag()" predicate.
* New: In Anabatic::AutoHorizontal, add the "drag" support.
The drag state can be known with the "::isDrag()" predicate.
In "::_makeDogleg()", when making a dogleg on a dragable segment
pass the drag state correctly and restrict the perpandicular span
of the perpandicular to the RoutingPad (though segment user constraints).
If we make a dogleg on the metal2 is it likely than we cannot go
straigth out vertically from the RoutingPad, so the new perpandicular
*is* restricted to the RoutingPad span.
Idem for AutoVertical.
* New: In Katana::Manipulator, add method "::dragMinimize()" which find a
hole where to minimize a draggable segment. We finally did not use it,
but keep it for potential further use.
* New: In Katana::PreProcess, adds a "protectAlignedaccesses()" local
function to check for vertically aligned metal1 RoutingPads, in that
case setup user constraints on the metal3 segments so they cannot
completly cover the other RoutingPad with metal2.
We also keep a "metal2protect()" function that create a fixed segment
to lock/protect a RoutingPad. Not used for now.
* New: In Katana::Session, add a RoutingPad locking event mechanism.
This allows us to request the creation of a locking (fixed segment)
over a draggable segment. Not used for now.
Lock events are processeds before all others as they create new
TrackElements.
* New: In Katana::Track, "::getNextFree()" and "::getPreviousFree()"
method to find the nearest free interval in a Track after/before a
position.
* Bug: In Anabatic::AutoHorizontal::getConstraints(), merge with user
constraints *only* if it's not an empty interval (as we use min/max
functions). Idem for AutoVertical.
* Bug: In AutoSegments_OnContacts::Locator::isValid(), the boolean test
must be inverted. Seems it never worked, but we never used it until
now...

* New: In Katana::PreProcess, adds a "protectAlignedaccesses()" local
function to check for vertically aligned metal1 RoutingPads, in that
case setup user constraints on the metal3 segments so they cannot
completly cover the other RoutingPad with metal2.
We also keep a "metal2protect()" function that create a fixed segment
to lock/protect a RoutingPad. Not used for now.
* New: In Katana::Session, add a RoutingPad locking event mechanism.
This allows us to request the creation of a locking (fixed segment)
over a draggable segment. Not used for now.
Lock events are processeds before all others as they create new
TrackElements.
* New: In Katana::Track, "::getNextFree()" and "::getPreviousFree()"
method to find the nearest free interval in a Track after/before a
position.
* Bug: In Anabatic::AutoHorizontal::getConstraints(), merge with user
constraints *only* if it's not an empty interval (as we use min/max
functions). Idem for AutoVertical.
* Bug: In AutoSegments_OnContacts::Locator::isValid(), the boolean test
must be inverted. Seems it never worked, but we never used it until
now...

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-).

Improved management of AutoContactTerminal for VH gauges (real ones).
* New: In Anabatic & Katana, add the new "drag" feature.
With VH gauges used by real technologies (M1-H, M2-V, M3-H) a new
routing configuration that was not efficiently handled did appear.
While the preferred routing direction for metal1 is officially
horizontal, due to the way the standard cell must be designed,
their metal1 terminals are still verticals (or punctuals).
Thus, when connecting to them, we face the case where the metal1
terminal (RoutingPad) is vertical *and* the metal2 wire is also
vertical. With that setup, the position of the AutoContactTerminal
via12 cannot be deduced, it may range all the way over the
metal1 RoutingPad. What may define it's position is the metal3 the
metal2 finally connects to. That, is, when we have one horizontal
(the metal3) and one vertical (the metal1 RoutingPad).
The intermediate wire of metal2 can be kept to a minimum size
by "dragging" the via12 close to the via23 when the metal3 wire is
moved.
* New: In Anabatic & Katana, problem of closely vertically aligneds
RoutingPads in metal1 is managed first in PreProcess by restricting
the span of the connecteds metal3 and in _makeDogleg also by restricting
the span even more tightly (to the RoutingPad itself).
* New: In Anabatic::AutoContactTerminal, add the "drag" support.
Automatically check if the connecting segment is in the same
direction as the RoutingPad, if so, sets the "SegDrag" flag.
The dragging state can be known with the "::canDrag()" predicate.
* New: In Anabatic::AutoHorizontal, add the "drag" support.
The drag state can be known with the "::isDrag()" predicate.
In "::_makeDogleg()", when making a dogleg on a dragable segment
pass the drag state correctly and restrict the perpandicular span
of the perpandicular to the RoutingPad (though segment user constraints).
If we make a dogleg on the metal2 is it likely than we cannot go
straigth out vertically from the RoutingPad, so the new perpandicular
*is* restricted to the RoutingPad span.
Idem for AutoVertical.
* New: In Katana::Manipulator, add method "::dragMinimize()" which find a
hole where to minimize a draggable segment. We finally did not use it,
but keep it for potential further use.
* New: In Katana::PreProcess, adds a "protectAlignedaccesses()" local
function to check for vertically aligned metal1 RoutingPads, in that

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()".

The drag state can be known with the "::isDrag()" predicate.
In "::_makeDogleg()", when making a dogleg on a dragable segment
pass the drag state correctly and restrict the perpandicular span
of the perpandicular to the RoutingPad (though segment user constraints).
If we make a dogleg on the metal2 is it likely than we cannot go
straigth out vertically from the RoutingPad, so the new perpandicular
*is* restricted to the RoutingPad span.
Idem for AutoVertical.
* New: In Katana::Manipulator, add method "::dragMinimize()" which find a
hole where to minimize a draggable segment. We finally did not use it,
but keep it for potential further use.
* New: In Katana::PreProcess, adds a "protectAlignedaccesses()" local
function to check for vertically aligned metal1 RoutingPads, in that
case setup user constraints on the metal3 segments so they cannot
completly cover the other RoutingPad with metal2.
We also keep a "metal2protect()" function that create a fixed segment
to lock/protect a RoutingPad. Not used for now.
* New: In Katana::Session, add a RoutingPad locking event mechanism.
This allows us to request the creation of a locking (fixed segment)
over a draggable segment. Not used for now.
Lock events are processeds before all others as they create new
TrackElements.
* New: In Katana::Track, "::getNextFree()" and "::getPreviousFree()"
method to find the nearest free interval in a Track after/before a
position.
* Bug: In Anabatic::AutoHorizontal::getConstraints(), merge with user
constraints *only* if it's not an empty interval (as we use min/max
functions). Idem for AutoVertical.
* Bug: In AutoSegments_OnContacts::Locator::isValid(), the boolean test
must be inverted. Seems it never worked, but we never used it until
now...

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-).

Improved management of AutoContactTerminal for VH gauges (real ones).
* New: In Anabatic & Katana, add the new "drag" feature.
With VH gauges used by real technologies (M1-H, M2-V, M3-H) a new
routing configuration that was not efficiently handled did appear.
While the preferred routing direction for metal1 is officially
horizontal, due to the way the standard cell must be designed,
their metal1 terminals are still verticals (or punctuals).
Thus, when connecting to them, we face the case where the metal1
terminal (RoutingPad) is vertical *and* the metal2 wire is also
vertical. With that setup, the position of the AutoContactTerminal
via12 cannot be deduced, it may range all the way over the
metal1 RoutingPad. What may define it's position is the metal3 the
metal2 finally connects to. That, is, when we have one horizontal
(the metal3) and one vertical (the metal1 RoutingPad).
The intermediate wire of metal2 can be kept to a minimum size
by "dragging" the via12 close to the via23 when the metal3 wire is
moved.
* New: In Anabatic & Katana, problem of closely vertically aligneds
RoutingPads in metal1 is managed first in PreProcess by restricting
the span of the connecteds metal3 and in _makeDogleg also by restricting
the span even more tightly (to the RoutingPad itself).
* New: In Anabatic::AutoContactTerminal, add the "drag" support.
Automatically check if the connecting segment is in the same
direction as the RoutingPad, if so, sets the "SegDrag" flag.
The dragging state can be known with the "::canDrag()" predicate.
* New: In Anabatic::AutoHorizontal, add the "drag" support.
The drag state can be known with the "::isDrag()" predicate.

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()".

Added analog type on segment NetRoutingProperty.
* New: In Anabatic_AutoSegments collection, added a Flag to the constructors
to allow different behavior between digital and analog modes.
For "Aligneds" and "Perpandiculars" collections, now manage a new
Flag WithDoglegs to follow aligned globals through local doglegs
(for analog nets).
Adjust the log level of collections to 144 (formerly 145).
* New: In Anabatic::AutoSegment, new flag SegAnalog for segments that are
part of an analog net.
Note that with this flag, we reach the 32 bits limit...
* Change: In Anabatic::Constants, Flags are now declared as BaseFlags
objects and *not* uint64_t. This avoids overload resolution problems with
arithmetical overload of the operators.
The BaseFlags/Flags types are now completly "isolated" from the
uint64_t, it has the advantage of showing where unwanted previous implicit
conversions where occuring.
* Change: In Katana::Constants, Flags values are now of BaseFlags type instead
of uint64_t.
* Change: In Anabatic::Dijkstra, lots of log cleanup.
* Change: In Anabatic::GCell::getSide(), make the "shrink" parameter visible
to allow to substract the topmost and rightmost track for axis span
computation in AutoSegment::computeOptimal(). Used for analog mode.
* Change: In NetRoutingState, added a flag for analog mode. Use uint32_t
for the flags type.
* New: In Isobar, export the NetRoutingState and NetRoutingExtension objects.

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()".

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...

though the GCell.

Replace "unsigned int" by "Flags" in all AutoSegments collections.
* Change: In Anabatic::AutoSegments collections, change the type of all
the flags that where in "unsigned int" (32 bits) to Flags (uint64_t)
as there is now more than 32 flags for functions.
* New: In Ababatic::Constants, added new flag Flags::WithPerpands, which
makes the number of flags tip over 32 bits, thus making mandatory
to uses Flags and not unsigned int.
* New: In Anabatic::AutoSegments_Perpandiculars, manage a new flag
Flags::WithDoglegs to allow to propagate through global segments that
are connecteds via doglegs on local segments. Meaning that there is
a good chance that they could be aligned.
Slighly change the way we propagate on aligned segments: no longer
check for VTee or HTee, but only for same direction and layer as
master.
* New: In Anabatic & Katana, replace all the "int", "long" and their
variants by the less implementation ambiguous "int32_t", "int64_t"
(and variant). This should help to better detect bit trucation in
flags.
Use the type to give a hint about the flags kind:
- Type "Flags", for flags shared among Anabatic & Katana
functions/methods (may also appear in some objects states).
- Type "uint32_t" for flags belonging to an object internal
state of from Hurricane functions flags (those should be
grouped in a Flag subclass in a perfect world).

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.

Katana manage wide wires, and they can also be symmetric.
* New: In Anabatic::AutoContact and the derived classes, manages wide
wires. The contact self dimension itself according to the segments
it is connected to. Special case for the AutoContactTerminal which
also read the size of the component it is anchored upon.
New refresh method "updateSize()" and flag CntInvalidatedWidth.
to compute the size.
In AutoContactTerminal, compute the constraint box according to
the width of the segment.
* New: In Anabatic::AutoSegment, flags are now implemented as "static const"
attributes of the class. The flags are stored into a uint64_t as
they are more than 32.
Added new flag "SegWide" and associated predicates.
* Change: In GCellTopology::_doHChannel() and GCellTopology::_doVChannel(),
uses the simpler overload of AutoSegment::create() in order to detect
the wire width automatically.
* New: In Katana::Manipulator, split insertToTrack() and forceToTrack()
into a one-track method and a segment level method that iterate over
the track span of the segment.
* New: In Katana::SegmentFsm, for each cost in the table, now allow access
to a specific track. So the base functions have now two parameters:
"icost" and "itrack" (has a cost can have multiple tracks in the case
of wide segments).
* Change: In Katana::TrackElement, remove the index of the element inside
it's track, as for a wide segment it will not be meaningful for the
non-base track. This means that we have to use the Track::find()
method each time instead.
Remove the wide flag, as it is a duplicate of the one in AutoSegment.
Added a getTrackCount() method to tell the number of track the
segment is inserted into. Needed in the Track destroy step to delete
a segment only when the last track that refers it is destroyed.
Added getSymmetricAxis() to correct the computation of the symmetric
base track in case of wide segment as the base track is not centered
but the the leftmost one.
* Change: In Track::insert() insert wide segments in their whole track span.
* Change: In TrackCost, create an array of costs according to the segment
track span.
* Change: In TrackSegment::create(), now activate the factory and create
wide segments.
* Bug: In Katana::AutoSegments_Perpandicular, correct the debug indentation
problem (ever shifting to the right).

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()

Replace "unsigned int" by "Flags" in all AutoSegments collections.
* Change: In Anabatic::AutoSegments collections, change the type of all
the flags that where in "unsigned int" (32 bits) to Flags (uint64_t)
as there is now more than 32 flags for functions.
* New: In Ababatic::Constants, added new flag Flags::WithPerpands, which
makes the number of flags tip over 32 bits, thus making mandatory
to uses Flags and not unsigned int.
* New: In Anabatic::AutoSegments_Perpandiculars, manage a new flag
Flags::WithDoglegs to allow to propagate through global segments that
are connecteds via doglegs on local segments. Meaning that there is
a good chance that they could be aligned.
Slighly change the way we propagate on aligned segments: no longer
check for VTee or HTee, but only for same direction and layer as
master.
* New: In Anabatic & Katana, replace all the "int", "long" and their
variants by the less implementation ambiguous "int32_t", "int64_t"
(and variant). This should help to better detect bit trucation in
flags.
Use the type to give a hint about the flags kind:
- Type "Flags", for flags shared among Anabatic & Katana
functions/methods (may also appear in some objects states).
- Type "uint32_t" for flags belonging to an object internal
state of from Hurricane functions flags (those should be
grouped in a Flag subclass in a perfect world).

Improved management of AutoContactTerminal for VH gauges (real ones).
* New: In Anabatic & Katana, add the new "drag" feature.
With VH gauges used by real technologies (M1-H, M2-V, M3-H) a new
routing configuration that was not efficiently handled did appear.
While the preferred routing direction for metal1 is officially
horizontal, due to the way the standard cell must be designed,
their metal1 terminals are still verticals (or punctuals).
Thus, when connecting to them, we face the case where the metal1
terminal (RoutingPad) is vertical *and* the metal2 wire is also
vertical. With that setup, the position of the AutoContactTerminal
via12 cannot be deduced, it may range all the way over the
metal1 RoutingPad. What may define it's position is the metal3 the
metal2 finally connects to. That, is, when we have one horizontal
(the metal3) and one vertical (the metal1 RoutingPad).
The intermediate wire of metal2 can be kept to a minimum size
by "dragging" the via12 close to the via23 when the metal3 wire is
moved.
* New: In Anabatic & Katana, problem of closely vertically aligneds
RoutingPads in metal1 is managed first in PreProcess by restricting
the span of the connecteds metal3 and in _makeDogleg also by restricting
the span even more tightly (to the RoutingPad itself).
* New: In Anabatic::AutoContactTerminal, add the "drag" support.
Automatically check if the connecting segment is in the same
direction as the RoutingPad, if so, sets the "SegDrag" flag.
The dragging state can be known with the "::canDrag()" predicate.
* New: In Anabatic::AutoHorizontal, add the "drag" support.
The drag state can be known with the "::isDrag()" predicate.
In "::_makeDogleg()", when making a dogleg on a dragable segment
pass the drag state correctly and restrict the perpandicular span
of the perpandicular to the RoutingPad (though segment user constraints).
If we make a dogleg on the metal2 is it likely than we cannot go
straigth out vertically from the RoutingPad, so the new perpandicular
*is* restricted to the RoutingPad span.
Idem for AutoVertical.
* New: In Katana::Manipulator, add method "::dragMinimize()" which find a
hole where to minimize a draggable segment. We finally did not use it,
but keep it for potential further use.
* New: In Katana::PreProcess, adds a "protectAlignedaccesses()" local
function to check for vertically aligned metal1 RoutingPads, in that
case setup user constraints on the metal3 segments so they cannot
completly cover the other RoutingPad with metal2.
We also keep a "metal2protect()" function that create a fixed segment
to lock/protect a RoutingPad. Not used for now.
* New: In Katana::Session, add a RoutingPad locking event mechanism.
This allows us to request the creation of a locking (fixed segment)
over a draggable segment. Not used for now.
Lock events are processeds before all others as they create new
TrackElements.
* New: In Katana::Track, "::getNextFree()" and "::getPreviousFree()"
method to find the nearest free interval in a Track after/before a
position.
* Bug: In Anabatic::AutoHorizontal::getConstraints(), merge with user
constraints *only* if it's not an empty interval (as we use min/max
functions). Idem for AutoVertical.
* Bug: In AutoSegments_OnContacts::Locator::isValid(), the boolean test
must be inverted. Seems it never worked, but we never used it until
now...

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.

Added analog type on segment NetRoutingProperty.
* New: In Anabatic_AutoSegments collection, added a Flag to the constructors
to allow different behavior between digital and analog modes.
For "Aligneds" and "Perpandiculars" collections, now manage a new
Flag WithDoglegs to follow aligned globals through local doglegs
(for analog nets).
Adjust the log level of collections to 144 (formerly 145).
* New: In Anabatic::AutoSegment, new flag SegAnalog for segments that are
part of an analog net.
Note that with this flag, we reach the 32 bits limit...
* Change: In Anabatic::Constants, Flags are now declared as BaseFlags
objects and *not* uint64_t. This avoids overload resolution problems with
arithmetical overload of the operators.
The BaseFlags/Flags types are now completly "isolated" from the
uint64_t, it has the advantage of showing where unwanted previous implicit
conversions where occuring.
* Change: In Katana::Constants, Flags values are now of BaseFlags type instead
of uint64_t.
* Change: In Anabatic::Dijkstra, lots of log cleanup.
* Change: In Anabatic::GCell::getSide(), make the "shrink" parameter visible
to allow to substract the topmost and rightmost track for axis span
computation in AutoSegment::computeOptimal(). Used for analog mode.
* Change: In NetRoutingState, added a flag for analog mode. Use uint32_t
for the flags type.
* New: In Isobar, export the NetRoutingState and NetRoutingExtension objects.

Improved management of AutoContactTerminal for VH gauges (real ones).
* New: In Anabatic & Katana, add the new "drag" feature.
With VH gauges used by real technologies (M1-H, M2-V, M3-H) a new
routing configuration that was not efficiently handled did appear.
While the preferred routing direction for metal1 is officially
horizontal, due to the way the standard cell must be designed,
their metal1 terminals are still verticals (or punctuals).
Thus, when connecting to them, we face the case where the metal1
terminal (RoutingPad) is vertical *and* the metal2 wire is also
vertical. With that setup, the position of the AutoContactTerminal
via12 cannot be deduced, it may range all the way over the
metal1 RoutingPad. What may define it's position is the metal3 the
metal2 finally connects to. That, is, when we have one horizontal
(the metal3) and one vertical (the metal1 RoutingPad).
The intermediate wire of metal2 can be kept to a minimum size
by "dragging" the via12 close to the via23 when the metal3 wire is
moved.
* New: In Anabatic & Katana, problem of closely vertically aligneds
RoutingPads in metal1 is managed first in PreProcess by restricting
the span of the connecteds metal3 and in _makeDogleg also by restricting
the span even more tightly (to the RoutingPad itself).
* New: In Anabatic::AutoContactTerminal, add the "drag" support.
Automatically check if the connecting segment is in the same
direction as the RoutingPad, if so, sets the "SegDrag" flag.
The dragging state can be known with the "::canDrag()" predicate.
* New: In Anabatic::AutoHorizontal, add the "drag" support.
The drag state can be known with the "::isDrag()" predicate.
In "::_makeDogleg()", when making a dogleg on a dragable segment
pass the drag state correctly and restrict the perpandicular span
of the perpandicular to the RoutingPad (though segment user constraints).
If we make a dogleg on the metal2 is it likely than we cannot go
straigth out vertically from the RoutingPad, so the new perpandicular
*is* restricted to the RoutingPad span.
Idem for AutoVertical.
* New: In Katana::Manipulator, add method "::dragMinimize()" which find a
hole where to minimize a draggable segment. We finally did not use it,
but keep it for potential further use.
* New: In Katana::PreProcess, adds a "protectAlignedaccesses()" local
function to check for vertically aligned metal1 RoutingPads, in that
case setup user constraints on the metal3 segments so they cannot
completly cover the other RoutingPad with metal2.
We also keep a "metal2protect()" function that create a fixed segment
to lock/protect a RoutingPad. Not used for now.
* New: In Katana::Session, add a RoutingPad locking event mechanism.
This allows us to request the creation of a locking (fixed segment)
over a draggable segment. Not used for now.
Lock events are processeds before all others as they create new
TrackElements.
* New: In Katana::Track, "::getNextFree()" and "::getPreviousFree()"
method to find the nearest free interval in a Track after/before a
position.
* Bug: In Anabatic::AutoHorizontal::getConstraints(), merge with user
constraints *only* if it's not an empty interval (as we use min/max
functions). Idem for AutoVertical.
* Bug: In AutoSegments_OnContacts::Locator::isValid(), the boolean test
must be inverted. Seems it never worked, but we never used it until
now...
