Improved UpdateSession & exception catching. Start of RoutingGauge implem.
Miscellaneous:
* Change: In <crlcore>, in display.conf use the same display threshold
for both METAL2 & METAL3.
In alliance.conf, the side of VIAs in the gauge is 2l (not 3l).
In kite.conf, separate edge densities for H/V.
* Change: In <Cell>, in flattenNets() use flag as argument, not a
boolean. Do not create rings for clock or supply nets.
* Change: In <DeepNet>, in _createRoutingPads() do not create rings
for clock or supply net (duplicated policy as in Cell::flattenNets()).
* Bug: In <ControllerWidget>, at last find the bad signal disconnect
that was causing ungraceful messages.
* Change: In <knik>, in Edge display occupancy/capacity in the string
name. Improved display progress and debugging capabilities.
Improved exception catch & breakpoint managment:
* Bug: In <PaletteWidget>, in updateExtensions() replace the calls to
deleteLayer() by delete. This cause the widget to be immediatly
erased instead of waiting for the event queue to be completly
processed. This was causing the widget to be left in a incoherent
state when stoping at a breakpoint.
* Bug: In <BreakpointWidget>, in execNoModal(), flush the main event
loop (QApplication::flush()) *before* lauching the *local* event
loop. This is to ensure all widgets are in their final state when
waiting (especially <PaletteWidget>).
* Change: In <ExceptionWidget>, new method catchAllWrapper() to
execute any std::function< void() > function/method with a "try"/
"catch" wraparound and lauch the widget in case something is catch.
* New: In <hurricane>, support for a oberver pattern, backported from
<katabatic> with an Obervable capable of being linked to any
number of Obervers.
* New: In <Cell>, made it observable to detect Cell change, currently
emit two kind of signals:
- Cell::CellAboutToChange : *before* any change.
- Cell::CellChanged : *after* the change has been completed.
* New: In <UpdateSession>, in Go::invalidate() add the Cell owning the
Go to the UPDATOR_STACK (of course the cell is added only once).
In addition, when the Cell is added, send a notification of
Cell::CellAboutToChange to all it's observers. The slave instances
are also invalidated.
Conversely in UpdateSession::_preDestroy() for each invalidated
Cell send a Cell::CellChanged notification to all observer.
The UPDATOR_STACK has been slightly amended to accept Cell which
are not Gos. Prior to this, the Cell where completly excluded from
the UpdateSession mechanism, so it's instances where never actualised
of anything referring to the Cell for that matter.
Note: we use two different mechanisms to transmit a Cell change,
observers and the slave instance map. I think at some point it
should be unificated.
* Change: In <CellViewer>, make it a Cell observer to redraw when the
cell is modificated (also update the palette).
Uses the catchAllWrapper() to protect all critical actions.
* Change: In <GraphicTool>, no longer need of cellPreModificated and
cellPostModificated signals. Now done through the Cell obersvers.
* Change: In <mauka>, <etesian> & <kite> now uses the catchAllWrapper
method for protection (need to split methods in two, to be able
to pass it as argument). No longer emit cellPreModificated and
cellPostModificated.
Support for RoutingGauge in P&R:
* Bug: In <placeandroute.py>, the connection from the internal power
ring to the connectors was not done correctly. Wrong contact layers
leading to a gap.
* Change: In <BuildPowerRails>, detection of the corona signals based
on how the "pck_px" pad is connected. No longer based on name
matching.
* Change: In <placeandroute.py>, support for 2 routing metal only
(3 metal in the technology).
* Change: In <katabatic> & <kite> support for a "top layer" limitation
on the routing gauge, this allows to use only two routing metals
(METAL2 & METAL3). Work in progress.

Support of RoutingGauge, part 2.
In Katabatic & Kite, remove all hard-coded values related to track pitches.
* New: In <Session>, add more convenience function to access RoutingGauge
characteristics.
* New: In <AutoSegment>, <AutoContact>, add support for the "depth spin",
that is, if the source/target contacts are going "top" or "down".
Used to compute the perpandicular pitch. Need a small modification
of the revalidation mechanism. The observers of <AutoSegment> are
notified when the spin changes.
* New: In <AutoSegment>, the getPPitch() method allow to compute the
"perpandicular pitch". For now it is simply the greatest from the
source perpandicular pitch and the target perpandicular pitch.
Make uses of the "depth spin".
* New: In <TrackElement>, <TrackSegment>, cache the perpandicular pitch.
Updated through the notification from the observable.

Add NetRoutingState (Property) on Nets to tell Kite what to do.
* New: In Katabatic, add the ability to decorate some (i.e. few) nets
with a state that indicate to Katabatic & Kite what to do with it.
The possible states are:
1. Fixed : all the wire are in fixed positions. The router cannot
move them and account them as obstacles.
2. ManualGlobalRoute : a user-defined topology is supplied. The
wires still have to be detailed route in "Detailed Pre-Route"
but will be skipped for the global routing and fixed for the
general Detailed route.
3. AutomaticGlobalRoute : ordinary nets, to be global routed then
detail routed.
4. Excluded : do not try to global or detail route thoses nets.
5. MixedPreRoute : mask combining Fixed and ManualGlobalRoute.
Not all nets have this property, only those that needs a special
processing.
To ease the access to the state, it is nested inside a
PrivateProperty in the net (NetRoutingProperty), with an extension
access class (NetRoutingExtension).
* New: In Kite, take account of NetRoutingState. Pointers to the
net's states are strored inside an internal map for faster access.
The property is *not* deleted when Kite is destroyed. The property
will remains until the Net itself is destroyed.
As a consequence, the lists that where passed to high level
function are removed as the information can now be accessed directly
through the net NetRoutingProperty.
* New: In Unicorn, in CgtMain, comply with the update interface.
* New: In documentation, update the User's Guide to explain the Pre-routed
step of Kite.

- New: In BuilPowerRails & BuildBlockage, specific support for chip-level
design. The Alliance "top chip" design hierarchical structure is
hard-coded. Top level POWER/GROUND/CLOCK nets must always have the
<vsse>, <vdde>, <ck>, <vssi>, <vddi>, <ckc>, <cki> names.
Specific method to get trans-hierarchical root nets, espcially in
case of global ones (POWER/GROUND). Clock is *not* global.
Some correction in the manner obscured tracks are computeds.
- New: ProtectRoutingPad module that perform a more clean work for protecting
unused RoutingPad.
- Bug: In BuildPowerRails, uses stable_sort<> instead of sort<>, which
causes unexplained core dumps (seems to try to perform a comparison
using the "end" pseudo element). Already occured in Knik, no explanation
other than a STL bug.
- Change: Slight changes in the weights to move up. Now needs a full empty
track instead of a half one.

* ./kite:
- Change: Propagate renaming "obstacle" -> "blockage".
- Bug/Change: In Configuration, the value of the extensionCap was too big
(1.5 lambda), reduce to 0.5 lambda. This is a problem, the extension
should be coupled to the layer as it is not the same for each METAL.
- Bug: When using TrackElement, always uses the virtual "->isFixed()" method
instead of trying to access to "->base()->isFixed()" as the base may be
NULL in case of blockage/fixed segment.
- Change: Merge PowerRails & Blockage trans-hierarchical construction (into
PowerRails). All blockages are groupeds under "blockagenet".
Allows to remove TrackBlockage & BuildBlockages.
- Change: In KiteEngine::annotateGloblalGraph(), when routing a full chip,
ring power segments around the core must completly saturate the edges
in their segment direction. This is to prevent the global router to
use paths under the power/ground ring (may generate unsolvable configs).
- Change: In KiteEngine::annotateGloblalGraph(), when routing a full chip,
distinguish three areas: the core (65%), the corona (90%) and the pads
(100%). Capacities on the edges are sets accordingly.
- Change: In RoutingEvent, introduce an alternative algorithm for
conflictSolve1, FindPath which try to deduce the breakpoints from a
truly explorated path. Unfortunatly this gives worst results than the
Cs1Candidates method. The why should be investigated as it's a critical
point in the algorithm.
- Change: In Manipulator::ripupPerpandicular(), when a caged perpandicular
is encountered, instead of just "stopping", rip it up and change is
axis hint (actually increase) it's axis hint so it stands a chance to
go outside the track with an obstacle.
- Change: In RoutingEvent/State::slackenTopology(), allow move up of local
segments when they are tightly constrained *and* blocked (cageds).
Partial modification of functions calls from booleans to flags.
- Bug: In NegociateWindow::NegociateOverlapCost, check for fixed segments
before trying to get DataNegociate. The lack of DataNegociate cause the
TrackElement to be discarted. It's a failsafe behavior, but it leads to
overlaps.
- Bug: In ProtectRoutingPad, in Pad Cells only, *do not* protect RoutingPad
to avoid the edge capacity over the pad to decrease to zero. This is
due to unused RoutingPads being accounted as blockages.

Etesian integration with Chip & ClockTree plugins.
* New: In Hurricane, in DebugSession, add a new method to activate the
trace inconditionally with a certain level.
* New: In Hurricane, in HyperNet, allow copy construction as there is
no reason to disallow it and we need it now.
* New: In Hurricane, in Cell::flattenNets(), add a new option to prevent
the flattening of the clock net(s). For more safety perform the
DeepNet creation *outside* the Collection loop.
* Bug: In Hurricane, in Cell_HyperNetRootNetOccurrences, skip the
DeepNets because they are the result of another flattening operation.
* New: In Isobar, in PyBasicLayer, export C++ method getBlockageLayer().
* New: In Isobar, in PyRoutingGauge, export C++ method getLayerPitch(),
needed by Cumulus plugins.
* New: In Etesian, EtesianEngine::findYSpin() to look for the Y orientation
if some cells are already placed. Typically the buffers of a clock
tree.
Pass the correct orienation to row_compatible_orientation().
Do not try to add feeds in the ISPD05 benchmarks. For now the
benchmarks are detected through their names (unreliable).
* Change: In Knik, in KnikEngine::initGlobalRouting(), allow the clock
to be routed as an ordinary signal when the clock tree is not
used.
* New: In Kite, in BuildPowerRails, management & detection for the
pre-routed clock.
In KiteEngine constructor, early initialization of the blockage
net to avoid later troubles in BuildPowerRails.
* New: In Cumulus, in ChipPlugin, add support for Etesian plus new
configuration parameter 'clockTree.placerEngine' to select between
Mauka and Etesian.
* New: In Cumulus, in BlockCorona, add blockages in the vertical sides
in the vertical layer to prevent the router to use the vertical
tracks in under the prower lines (for example, blockage in M3
with power line M5).
In Cumulus, in ChipConf add attribute to access the blockage net.
* New: In Cumulus, when the clock tree is disabled, do not generate
the last rail around the block (the clock rail).
* Bug: In Cumulus, in ChipConf use the clock pad to guess the clock
signals and *not* the power pad.
Add more meaningful error messages if a pad global signal is
not found (implicit connexion by name).
* Bug: In Cumulus, in ClockTree, compute correctly the cells Y spin,
that is *from the bottom of the cell AB* (not from 'zero').

* New: In Katabatic, add the ability to decorate some (i.e. few) nets
with a state that indicate to Katabatic & Kite what to do with it.
The possible states are:
1. Fixed : all the wire are in fixed positions. The router cannot
move them and account them as obstacles.
2. ManualGlobalRoute : a user-defined topology is supplied. The
wires still have to be detailed route in "Detailed Pre-Route"
but will be skipped for the global routing and fixed for the
general Detailed route.
3. AutomaticGlobalRoute : ordinary nets, to be global routed then
detail routed.
4. Excluded : do not try to global or detail route thoses nets.
5. MixedPreRoute : mask combining Fixed and ManualGlobalRoute.
Not all nets have this property, only those that needs a special
processing.
To ease the access to the state, it is nested inside a
PrivateProperty in the net (NetRoutingProperty), with an extension
access class (NetRoutingExtension).
* New: In Kite, take account of NetRoutingState. Pointers to the
net's states are strored inside an internal map for faster access.
The property is *not* deleted when Kite is destroyed. The property
will remains until the Net itself is destroyed.
As a consequence, the lists that where passed to high level
function are removed as the information can now be accessed directly
through the net NetRoutingProperty.
* New: In Unicorn, in CgtMain, comply with the update interface.
* New: In documentation, update the User's Guide to explain the Pre-routed
step of Kite.

Implementation of pre-routing support (for clock-tree compliance).
* New: In Katabatic, in <AutoContact>, this class is no longer derived
from ExtentionGo. With the simplificated AutoContacts, there is no
reason to do so, and it will save some QuadTree insertions/deletions.
New factory function AutoContact::createFrom(Contact*) which try to
build an AutoContact on top of a Hurricane::Contact. Of course that
base contact *must fit* into one of the predefined Contact
configurations (Terminal, Turn, HTee or VTee).
NOTE: This implies that the pre-routed segments & contacts *are*
correctly articulated, which is not the case when a Cell is read
from disk in "ap" format. The pre-routing feature must be used for
now without any re-read from disk. We will implement a re-articulating
pre-process in the future.
* Change: In Katabatic, in <AutoContact> derived classes, the ::updateCache()
method now display an accurate error message if a segment is connected
but has no AutoSegment conterpart (i.e. the lookup fails).
* New: In Katabatic, in <AutoSegment>, the ::computeOptimal() method is
short-circuited for pre-routed segments, the optimal axis position is
considered to be the one it is currently on (i.e. we trust the designer).
* New: In Katabatic, in <KatabaticEngine>, the ::loadGlobalRouting()
method now accept a map of excluded nets (same as Knik). This map is
the one of pre-routed nets.
* New: In Katabatic, in layer assignment, do not try to displace fixed
segments...
* New: In Katabatic, in <AutoSegment>, new flag SegUserDefined and related
methods to know if a segment comes from the global router (Knik) or
is pre-routed (supplied by the user).
* New: In Kite, In <BuildPowerRails>, support (exclusion) for pre-routed
nets.
* New: In Kite, In <GraphicKiteEngine> new menu entry for running the
router on pre-routed nets ("Detailed Pre-Route"), also integrated
in the all-on-one route command.
* New: In Kite, In KiteEngine, new method ::_initDataBase() that group
all the initialisation steps. It is a mix of calls between Knik and
Kite initializations which are intertwinneds (may have to devellop
a shared common base at a later point). It creates the Knik grid,
then the Katabatic grid, then load pre-routed wires and power rails
and protect isolated RoutingPads.
Add support for a map of pre-routed nets (to be excluded for
Knik calls).
The method "::run()" now uses function flags, firstly to know if
it is managing pre-routed wires or general purposes ones.
* New: In Kite, in <NegociateWindow>, the "::run()" methods has now two
modes. The normal one and the 'KtPreRoutedStage' that is for routing
pre-routed nets. When in pre-route stage, the wires are fixed at the
end of this step.
* New: In Kite, in <TrackElement> add decorator for AutoSegment
isUsedDefined().
* New: In Kite, in <TrackSegment>, the various ::canDogleg() methods
returns false for a pre-routed (user-defined segment).
* New: In Kite, in PyKiteEngine, added new method runNegociatePreRouted().

- Change: Propagate renaming "obstacle" -> "blockage".
- Bug/Change: In Configuration, the value of the extensionCap was too big
(1.5 lambda), reduce to 0.5 lambda. This is a problem, the extension
should be coupled to the layer as it is not the same for each METAL.
- Bug: When using TrackElement, always uses the virtual "->isFixed()" method
instead of trying to access to "->base()->isFixed()" as the base may be
NULL in case of blockage/fixed segment.
- Change: Merge PowerRails & Blockage trans-hierarchical construction (into
PowerRails). All blockages are groupeds under "blockagenet".
Allows to remove TrackBlockage & BuildBlockages.
- Change: In KiteEngine::annotateGloblalGraph(), when routing a full chip,
ring power segments around the core must completly saturate the edges
in their segment direction. This is to prevent the global router to
use paths under the power/ground ring (may generate unsolvable configs).
- Change: In KiteEngine::annotateGloblalGraph(), when routing a full chip,
distinguish three areas: the core (65%), the corona (90%) and the pads
(100%). Capacities on the edges are sets accordingly.
- Change: In RoutingEvent, introduce an alternative algorithm for
conflictSolve1, FindPath which try to deduce the breakpoints from a
truly explorated path. Unfortunatly this gives worst results than the
Cs1Candidates method. The why should be investigated as it's a critical
point in the algorithm.
- Change: In Manipulator::ripupPerpandicular(), when a caged perpandicular
is encountered, instead of just "stopping", rip it up and change is
axis hint (actually increase) it's axis hint so it stands a chance to
go outside the track with an obstacle.
- Change: In RoutingEvent/State::slackenTopology(), allow move up of local
segments when they are tightly constrained *and* blocked (cageds).
Partial modification of functions calls from booleans to flags.
- Bug: In NegociateWindow::NegociateOverlapCost, check for fixed segments
before trying to get DataNegociate. The lack of DataNegociate cause the
TrackElement to be discarted. It's a failsafe behavior, but it leads to
overlaps.
- Bug: In ProtectRoutingPad, in Pad Cells only, *do not* protect RoutingPad
to avoid the edge capacity over the pad to decrease to zero. This is
due to unused RoutingPads being accounted as blockages.

Improved UpdateSession & exception catching. Start of RoutingGauge implem.
Miscellaneous:
* Change: In <crlcore>, in display.conf use the same display threshold
for both METAL2 & METAL3.
In alliance.conf, the side of VIAs in the gauge is 2l (not 3l).
In kite.conf, separate edge densities for H/V.
* Change: In <Cell>, in flattenNets() use flag as argument, not a
boolean. Do not create rings for clock or supply nets.
* Change: In <DeepNet>, in _createRoutingPads() do not create rings
for clock or supply net (duplicated policy as in Cell::flattenNets()).
* Bug: In <ControllerWidget>, at last find the bad signal disconnect
that was causing ungraceful messages.
* Change: In <knik>, in Edge display occupancy/capacity in the string
name. Improved display progress and debugging capabilities.
Improved exception catch & breakpoint managment:
* Bug: In <PaletteWidget>, in updateExtensions() replace the calls to
deleteLayer() by delete. This cause the widget to be immediatly
erased instead of waiting for the event queue to be completly
processed. This was causing the widget to be left in a incoherent
state when stoping at a breakpoint.
* Bug: In <BreakpointWidget>, in execNoModal(), flush the main event
loop (QApplication::flush()) *before* lauching the *local* event
loop. This is to ensure all widgets are in their final state when
waiting (especially <PaletteWidget>).
* Change: In <ExceptionWidget>, new method catchAllWrapper() to
execute any std::function< void() > function/method with a "try"/
"catch" wraparound and lauch the widget in case something is catch.
* New: In <hurricane>, support for a oberver pattern, backported from
<katabatic> with an Obervable capable of being linked to any
number of Obervers.
* New: In <Cell>, made it observable to detect Cell change, currently
emit two kind of signals:
- Cell::CellAboutToChange : *before* any change.
- Cell::CellChanged : *after* the change has been completed.
* New: In <UpdateSession>, in Go::invalidate() add the Cell owning the
Go to the UPDATOR_STACK (of course the cell is added only once).
In addition, when the Cell is added, send a notification of
Cell::CellAboutToChange to all it's observers. The slave instances
are also invalidated.
Conversely in UpdateSession::_preDestroy() for each invalidated
Cell send a Cell::CellChanged notification to all observer.
The UPDATOR_STACK has been slightly amended to accept Cell which
are not Gos. Prior to this, the Cell where completly excluded from
the UpdateSession mechanism, so it's instances where never actualised
of anything referring to the Cell for that matter.
Note: we use two different mechanisms to transmit a Cell change,
observers and the slave instance map. I think at some point it
should be unificated.
* Change: In <CellViewer>, make it a Cell observer to redraw when the
cell is modificated (also update the palette).
Uses the catchAllWrapper() to protect all critical actions.
* Change: In <GraphicTool>, no longer need of cellPreModificated and
cellPostModificated signals. Now done through the Cell obersvers.
* Change: In <mauka>, <etesian> & <kite> now uses the catchAllWrapper
method for protection (need to split methods in two, to be able
to pass it as argument). No longer emit cellPreModificated and
cellPostModificated.
Support for RoutingGauge in P&R:
* Bug: In <placeandroute.py>, the connection from the internal power
ring to the connectors was not done correctly. Wrong contact layers
leading to a gap.
* Change: In <BuildPowerRails>, detection of the corona signals based
on how the "pck_px" pad is connected. No longer based on name
matching.
* Change: In <placeandroute.py>, support for 2 routing metal only
(3 metal in the technology).
* Change: In <katabatic> & <kite> support for a "top layer" limitation
on the routing gauge, this allows to use only two routing metals
(METAL2 & METAL3). Work in progress.

Express "xEdgeCapacity" ratio as "xTracksReservedLocal" a number of tracks.
* Change: In Kite, Katabatic & Knik, express the number of tracks truly
available to the global router by the number of tracks reserved to
the local routage inside a GCell. Replace the ratio parameter
"hEdgeCapacity" by an integer parameter "hTracksReservedLocal"
(duplicate for verticals).
It is more explicit to give directly the number of tracks that
are to be used locally, and potentially saves us from rouding
problems when calculating the number of availables tracks.
Note: we cannot do that for the layer saturateRatio as it
uses the density ratio that take account local wires, leading
to fractional results.
* Change: In Katabatic, in <GCellGrid>, rename checkEdgeSaturation()
into checkEdgeOverflow(), more explicit.
* Change: In Knik, in <Graph>, display the computed capacities of the
lower left node edges (should be the same througout all the grid).
* Change: In Unicorn, in <cgt.py>, uses the new parameters names for
edge density.

- New: In NegociateWindow/RoutingEvent, adds a more comprehensive stage
"Repair". Perform in three stage: first try to place with a relaxed
constraint (one GCell on each side). Second try to minimize the faulty
segment. Third perform another "repack perpandicular" but this time
the faulty segment is re-inserted *before* any of it's perpandiculars.
- New: In RoutingEvent::cacheAxisHint(), when a segment has a parent, that
is comes for a "moveUp()", uses the parent axis hint as it's own.
- New: In State::slackenTopology(), in the global FSM, adds a special
operation when reaching MaximumSlack: forceOverLocals(), try to insert
the global on track containing only local segments. Should tend to
concentrate locals on a small set of shared tracks. Most useful on the
highest layers.
- New: In State::slackenTopology(), in the "MoveUp" state, try to find the
more appropriate segment to move up (Manipulator::desaturate()).
Effectively move up the longest segment fully enclosing the one we are
processing.
- New: In State::slackenTopology(), add a check for fully blocked segments
in the local segment FSM. Calls State::solveFullBlocked().
- New: In KiteEngine::createGlobalGraph(), decrease the vertical capacity
of one track inside the core. Helps smooth the vertical density.
- Change: In Manipulator::insertInTrack(), when a track is freed for a
to be inserted changes the priorities so that the segment is immediatly
inserted. Parallels ripeds and theirs perpandiculars are replaced
only *after*. This is the opposite of the previous behavior.
- Change: In NegociateWindow::NegociateOverlapCost(), account the costs
of terminals only for deep depth layers (M1, M2 & M3).
- Change: In RoutingEvent::insertInTrack(), expand the excluded interval
by a half-pitch (2.5l) instead of one lambda.
- Change: In State::State(), do not uses DiscardGlobal if the ripup count
exceed 5. Case of the "Strap" segments that can be ripped a lot
before changing state.
- Change: In State::_processNegociate(), no longer lock into position
(fixed) the local terminal segments as a last resort.
- Change: In RoutingEvent::_processNegociate(), no longer ripup perpandiculars
when a segment is inserted in a free space. Reduce the number of
events whithout degrading the routing quality.
- Change: In State::conflictSolve1_v1b(), if getLongestConflict() is nul,
ignore the track, the conflict must occurs on another track.
- Change: In TrackCost, add a flag support. First uses, a flags to prevent
a local of the topmost layer to ripup a global which is in moveUp
state.
- Bug: In State::solveFullBlockage(), after have been freed, reset the
segment state to "moveUp".
- Bug: In manipulator::minimize(), the axisHint was miscalculated if the
punctual span was empty.

- Bug/Change: In Configuration, the value of the extensionCap was too big
(1.5 lambda), reduce to 0.5 lambda. This is a problem, the extension
should be coupled to the layer as it is not the same for each METAL.
- Bug: When using TrackElement, always uses the virtual "->isFixed()" method
instead of trying to access to "->base()->isFixed()" as the base may be
NULL in case of blockage/fixed segment.
- Change: Merge PowerRails & Blockage trans-hierarchical construction (into
PowerRails). All blockages are groupeds under "blockagenet".
Allows to remove TrackBlockage & BuildBlockages.
- Change: In KiteEngine::annotateGloblalGraph(), when routing a full chip,
ring power segments around the core must completly saturate the edges
in their segment direction. This is to prevent the global router to
use paths under the power/ground ring (may generate unsolvable configs).
- Change: In KiteEngine::annotateGloblalGraph(), when routing a full chip,
distinguish three areas: the core (65%), the corona (90%) and the pads
(100%). Capacities on the edges are sets accordingly.
- Change: In RoutingEvent, introduce an alternative algorithm for
conflictSolve1, FindPath which try to deduce the breakpoints from a
truly explorated path. Unfortunatly this gives worst results than the
Cs1Candidates method. The why should be investigated as it's a critical
point in the algorithm.
- Change: In Manipulator::ripupPerpandicular(), when a caged perpandicular
is encountered, instead of just "stopping", rip it up and change is
axis hint (actually increase) it's axis hint so it stands a chance to
go outside the track with an obstacle.
- Change: In RoutingEvent/State::slackenTopology(), allow move up of local
segments when they are tightly constrained *and* blocked (cageds).
Partial modification of functions calls from booleans to flags.
- Bug: In NegociateWindow::NegociateOverlapCost, check for fixed segments
before trying to get DataNegociate. The lack of DataNegociate cause the
TrackElement to be discarted. It's a failsafe behavior, but it leads to
overlaps.
- Bug: In ProtectRoutingPad, in Pad Cells only, *do not* protect RoutingPad
to avoid the edge capacity over the pad to decrease to zero. This is
due to unused RoutingPads being accounted as blockages.

Improved UpdateSession & exception catching. Start of RoutingGauge implem.
Miscellaneous:
* Change: In <crlcore>, in display.conf use the same display threshold
for both METAL2 & METAL3.
In alliance.conf, the side of VIAs in the gauge is 2l (not 3l).
In kite.conf, separate edge densities for H/V.
* Change: In <Cell>, in flattenNets() use flag as argument, not a
boolean. Do not create rings for clock or supply nets.
* Change: In <DeepNet>, in _createRoutingPads() do not create rings
for clock or supply net (duplicated policy as in Cell::flattenNets()).
* Bug: In <ControllerWidget>, at last find the bad signal disconnect
that was causing ungraceful messages.
* Change: In <knik>, in Edge display occupancy/capacity in the string
name. Improved display progress and debugging capabilities.
Improved exception catch & breakpoint managment:
* Bug: In <PaletteWidget>, in updateExtensions() replace the calls to
deleteLayer() by delete. This cause the widget to be immediatly
erased instead of waiting for the event queue to be completly
processed. This was causing the widget to be left in a incoherent
state when stoping at a breakpoint.
* Bug: In <BreakpointWidget>, in execNoModal(), flush the main event
loop (QApplication::flush()) *before* lauching the *local* event
loop. This is to ensure all widgets are in their final state when
waiting (especially <PaletteWidget>).
* Change: In <ExceptionWidget>, new method catchAllWrapper() to
execute any std::function< void() > function/method with a "try"/
"catch" wraparound and lauch the widget in case something is catch.
* New: In <hurricane>, support for a oberver pattern, backported from
<katabatic> with an Obervable capable of being linked to any
number of Obervers.
* New: In <Cell>, made it observable to detect Cell change, currently
emit two kind of signals:
- Cell::CellAboutToChange : *before* any change.
- Cell::CellChanged : *after* the change has been completed.
* New: In <UpdateSession>, in Go::invalidate() add the Cell owning the
Go to the UPDATOR_STACK (of course the cell is added only once).
In addition, when the Cell is added, send a notification of
Cell::CellAboutToChange to all it's observers. The slave instances
are also invalidated.
Conversely in UpdateSession::_preDestroy() for each invalidated
Cell send a Cell::CellChanged notification to all observer.
The UPDATOR_STACK has been slightly amended to accept Cell which
are not Gos. Prior to this, the Cell where completly excluded from
the UpdateSession mechanism, so it's instances where never actualised
of anything referring to the Cell for that matter.
Note: we use two different mechanisms to transmit a Cell change,
observers and the slave instance map. I think at some point it
should be unificated.
* Change: In <CellViewer>, make it a Cell observer to redraw when the
cell is modificated (also update the palette).
Uses the catchAllWrapper() to protect all critical actions.
* Change: In <GraphicTool>, no longer need of cellPreModificated and
cellPostModificated signals. Now done through the Cell obersvers.
* Change: In <mauka>, <etesian> & <kite> now uses the catchAllWrapper
method for protection (need to split methods in two, to be able
to pass it as argument). No longer emit cellPreModificated and
cellPostModificated.
Support for RoutingGauge in P&R:
* Bug: In <placeandroute.py>, the connection from the internal power
ring to the connectors was not done correctly. Wrong contact layers
leading to a gap.
* Change: In <BuildPowerRails>, detection of the corona signals based
on how the "pck_px" pad is connected. No longer based on name
matching.
* Change: In <placeandroute.py>, support for 2 routing metal only
(3 metal in the technology).
* Change: In <katabatic> & <kite> support for a "top layer" limitation
on the routing gauge, this allows to use only two routing metals
(METAL2 & METAL3). Work in progress.

Express "xEdgeCapacity" ratio as "xTracksReservedLocal" a number of tracks.
* Change: In Kite, Katabatic & Knik, express the number of tracks truly
available to the global router by the number of tracks reserved to
the local routage inside a GCell. Replace the ratio parameter
"hEdgeCapacity" by an integer parameter "hTracksReservedLocal"
(duplicate for verticals).
It is more explicit to give directly the number of tracks that
are to be used locally, and potentially saves us from rouding
problems when calculating the number of availables tracks.
Note: we cannot do that for the layer saturateRatio as it
uses the density ratio that take account local wires, leading
to fractional results.
* Change: In Katabatic, in <GCellGrid>, rename checkEdgeSaturation()
into checkEdgeOverflow(), more explicit.
* Change: In Knik, in <Graph>, display the computed capacities of the
lower left node edges (should be the same througout all the grid).

- New: In RoutingEvent::cacheAxisHint(), when a segment has a parent, that
is comes for a "moveUp()", uses the parent axis hint as it's own.
- New: In State::slackenTopology(), in the global FSM, adds a special
operation when reaching MaximumSlack: forceOverLocals(), try to insert
the global on track containing only local segments. Should tend to
concentrate locals on a small set of shared tracks. Most useful on the
highest layers.
- New: In State::slackenTopology(), in the "MoveUp" state, try to find the
more appropriate segment to move up (Manipulator::desaturate()).
Effectively move up the longest segment fully enclosing the one we are
processing.
- New: In State::slackenTopology(), add a check for fully blocked segments
in the local segment FSM. Calls State::solveFullBlocked().
- New: In KiteEngine::createGlobalGraph(), decrease the vertical capacity
of one track inside the core. Helps smooth the vertical density.
- Change: In Manipulator::insertInTrack(), when a track is freed for a
to be inserted changes the priorities so that the segment is immediatly
inserted. Parallels ripeds and theirs perpandiculars are replaced
only *after*. This is the opposite of the previous behavior.
- Change: In NegociateWindow::NegociateOverlapCost(), account the costs
of terminals only for deep depth layers (M1, M2 & M3).
- Change: In RoutingEvent::insertInTrack(), expand the excluded interval
by a half-pitch (2.5l) instead of one lambda.
- Change: In State::State(), do not uses DiscardGlobal if the ripup count
exceed 5. Case of the "Strap" segments that can be ripped a lot
before changing state.
- Change: In State::_processNegociate(), no longer lock into position
(fixed) the local terminal segments as a last resort.
- Change: In RoutingEvent::_processNegociate(), no longer ripup perpandiculars
when a segment is inserted in a free space. Reduce the number of
events whithout degrading the routing quality.
- Change: In State::conflictSolve1_v1b(), if getLongestConflict() is nul,
ignore the track, the conflict must occurs on another track.
- Change: In TrackCost, add a flag support. First uses, a flags to prevent
a local of the topmost layer to ripup a global which is in moveUp
state.
- Bug: In State::solveFullBlockage(), after have been freed, reset the
segment state to "moveUp".
- Bug: In manipulator::minimize(), the axisHint was miscalculated if the
punctual span was empty.

Express "xEdgeCapacity" ratio as "xTracksReservedLocal" a number of tracks.
* Change: In Kite, Katabatic & Knik, express the number of tracks truly
available to the global router by the number of tracks reserved to
the local routage inside a GCell. Replace the ratio parameter
"hEdgeCapacity" by an integer parameter "hTracksReservedLocal"
(duplicate for verticals).
It is more explicit to give directly the number of tracks that
are to be used locally, and potentially saves us from rouding
problems when calculating the number of availables tracks.
Note: we cannot do that for the layer saturateRatio as it
uses the density ratio that take account local wires, leading
to fractional results.
* Change: In Katabatic, in <GCellGrid>, rename checkEdgeSaturation()
into checkEdgeOverflow(), more explicit.
* Change: In Knik, in <Graph>, display the computed capacities of the
lower left node edges (should be the same througout all the grid).
* Change: In Unicorn, in <cgt.py>, uses the new parameters names for
edge density.

Improved UpdateSession & exception catching. Start of RoutingGauge implem.
Miscellaneous:
* Change: In <crlcore>, in display.conf use the same display threshold
for both METAL2 & METAL3.
In alliance.conf, the side of VIAs in the gauge is 2l (not 3l).
In kite.conf, separate edge densities for H/V.
* Change: In <Cell>, in flattenNets() use flag as argument, not a
boolean. Do not create rings for clock or supply nets.
* Change: In <DeepNet>, in _createRoutingPads() do not create rings
for clock or supply net (duplicated policy as in Cell::flattenNets()).
* Bug: In <ControllerWidget>, at last find the bad signal disconnect
that was causing ungraceful messages.
* Change: In <knik>, in Edge display occupancy/capacity in the string
name. Improved display progress and debugging capabilities.
Improved exception catch & breakpoint managment:
* Bug: In <PaletteWidget>, in updateExtensions() replace the calls to
deleteLayer() by delete. This cause the widget to be immediatly
erased instead of waiting for the event queue to be completly
processed. This was causing the widget to be left in a incoherent
state when stoping at a breakpoint.
* Bug: In <BreakpointWidget>, in execNoModal(), flush the main event
loop (QApplication::flush()) *before* lauching the *local* event
loop. This is to ensure all widgets are in their final state when
waiting (especially <PaletteWidget>).
* Change: In <ExceptionWidget>, new method catchAllWrapper() to
execute any std::function< void() > function/method with a "try"/
"catch" wraparound and lauch the widget in case something is catch.
* New: In <hurricane>, support for a oberver pattern, backported from
<katabatic> with an Obervable capable of being linked to any
number of Obervers.
* New: In <Cell>, made it observable to detect Cell change, currently
emit two kind of signals:
- Cell::CellAboutToChange : *before* any change.
- Cell::CellChanged : *after* the change has been completed.
* New: In <UpdateSession>, in Go::invalidate() add the Cell owning the
Go to the UPDATOR_STACK (of course the cell is added only once).
In addition, when the Cell is added, send a notification of
Cell::CellAboutToChange to all it's observers. The slave instances
are also invalidated.
Conversely in UpdateSession::_preDestroy() for each invalidated
Cell send a Cell::CellChanged notification to all observer.
The UPDATOR_STACK has been slightly amended to accept Cell which
are not Gos. Prior to this, the Cell where completly excluded from
the UpdateSession mechanism, so it's instances where never actualised
of anything referring to the Cell for that matter.
Note: we use two different mechanisms to transmit a Cell change,
observers and the slave instance map. I think at some point it
should be unificated.
* Change: In <CellViewer>, make it a Cell observer to redraw when the
cell is modificated (also update the palette).
Uses the catchAllWrapper() to protect all critical actions.
* Change: In <GraphicTool>, no longer need of cellPreModificated and
cellPostModificated signals. Now done through the Cell obersvers.
* Change: In <mauka>, <etesian> & <kite> now uses the catchAllWrapper
method for protection (need to split methods in two, to be able
to pass it as argument). No longer emit cellPreModificated and
cellPostModificated.
Support for RoutingGauge in P&R:
* Bug: In <placeandroute.py>, the connection from the internal power
ring to the connectors was not done correctly. Wrong contact layers
leading to a gap.
* Change: In <BuildPowerRails>, detection of the corona signals based
on how the "pck_px" pad is connected. No longer based on name
matching.
* Change: In <placeandroute.py>, support for 2 routing metal only
(3 metal in the technology).
* Change: In <katabatic> & <kite> support for a "top layer" limitation
on the routing gauge, this allows to use only two routing metals
(METAL2 & METAL3). Work in progress.

- Change: Propagate renaming "obstacle" -> "blockage".
- Bug/Change: In Configuration, the value of the extensionCap was too big
(1.5 lambda), reduce to 0.5 lambda. This is a problem, the extension
should be coupled to the layer as it is not the same for each METAL.
- Bug: When using TrackElement, always uses the virtual "->isFixed()" method
instead of trying to access to "->base()->isFixed()" as the base may be
NULL in case of blockage/fixed segment.
- Change: Merge PowerRails & Blockage trans-hierarchical construction (into
PowerRails). All blockages are groupeds under "blockagenet".
Allows to remove TrackBlockage & BuildBlockages.
- Change: In KiteEngine::annotateGloblalGraph(), when routing a full chip,
ring power segments around the core must completly saturate the edges
in their segment direction. This is to prevent the global router to
use paths under the power/ground ring (may generate unsolvable configs).
- Change: In KiteEngine::annotateGloblalGraph(), when routing a full chip,
distinguish three areas: the core (65%), the corona (90%) and the pads
(100%). Capacities on the edges are sets accordingly.
- Change: In RoutingEvent, introduce an alternative algorithm for
conflictSolve1, FindPath which try to deduce the breakpoints from a
truly explorated path. Unfortunatly this gives worst results than the
Cs1Candidates method. The why should be investigated as it's a critical
point in the algorithm.
- Change: In Manipulator::ripupPerpandicular(), when a caged perpandicular
is encountered, instead of just "stopping", rip it up and change is
axis hint (actually increase) it's axis hint so it stands a chance to
go outside the track with an obstacle.
- Change: In RoutingEvent/State::slackenTopology(), allow move up of local
segments when they are tightly constrained *and* blocked (cageds).
Partial modification of functions calls from booleans to flags.
- Bug: In NegociateWindow::NegociateOverlapCost, check for fixed segments
before trying to get DataNegociate. The lack of DataNegociate cause the
TrackElement to be discarted. It's a failsafe behavior, but it leads to
overlaps.
- Bug: In ProtectRoutingPad, in Pad Cells only, *do not* protect RoutingPad
to avoid the edge capacity over the pad to decrease to zero. This is
due to unused RoutingPads being accounted as blockages.

execute any std::function< void() > function/method with a "try"/
"catch" wraparound and lauch the widget in case something is catch.
* New: In <hurricane>, support for a oberver pattern, backported from
<katabatic> with an Obervable capable of being linked to any
number of Obervers.
* New: In <Cell>, made it observable to detect Cell change, currently
emit two kind of signals:
- Cell::CellAboutToChange : *before* any change.
- Cell::CellChanged : *after* the change has been completed.
* New: In <UpdateSession>, in Go::invalidate() add the Cell owning the
Go to the UPDATOR_STACK (of course the cell is added only once).
In addition, when the Cell is added, send a notification of
Cell::CellAboutToChange to all it's observers. The slave instances
are also invalidated.
Conversely in UpdateSession::_preDestroy() for each invalidated
Cell send a Cell::CellChanged notification to all observer.
The UPDATOR_STACK has been slightly amended to accept Cell which
are not Gos. Prior to this, the Cell where completly excluded from
the UpdateSession mechanism, so it's instances where never actualised
of anything referring to the Cell for that matter.
Note: we use two different mechanisms to transmit a Cell change,
observers and the slave instance map. I think at some point it
should be unificated.
* Change: In <CellViewer>, make it a Cell observer to redraw when the
cell is modificated (also update the palette).
Uses the catchAllWrapper() to protect all critical actions.
* Change: In <GraphicTool>, no longer need of cellPreModificated and
cellPostModificated signals. Now done through the Cell obersvers.
* Change: In <mauka>, <etesian> & <kite> now uses the catchAllWrapper
method for protection (need to split methods in two, to be able
to pass it as argument). No longer emit cellPreModificated and
cellPostModificated.
Support for RoutingGauge in P&R:
* Bug: In <placeandroute.py>, the connection from the internal power
ring to the connectors was not done correctly. Wrong contact layers
leading to a gap.
* Change: In <BuildPowerRails>, detection of the corona signals based
on how the "pck_px" pad is connected. No longer based on name
matching.
* Change: In <placeandroute.py>, support for 2 routing metal only
(3 metal in the technology).
* Change: In <katabatic> & <kite> support for a "top layer" limitation
on the routing gauge, this allows to use only two routing metals
(METAL2 & METAL3). Work in progress.

- Change: Propagate renaming "obstacle" -> "blockage".
- Bug/Change: In Configuration, the value of the extensionCap was too big
(1.5 lambda), reduce to 0.5 lambda. This is a problem, the extension
should be coupled to the layer as it is not the same for each METAL.
- Bug: When using TrackElement, always uses the virtual "->isFixed()" method
instead of trying to access to "->base()->isFixed()" as the base may be
NULL in case of blockage/fixed segment.
- Change: Merge PowerRails & Blockage trans-hierarchical construction (into
PowerRails). All blockages are groupeds under "blockagenet".
Allows to remove TrackBlockage & BuildBlockages.
- Change: In KiteEngine::annotateGloblalGraph(), when routing a full chip,
ring power segments around the core must completly saturate the edges
in their segment direction. This is to prevent the global router to
use paths under the power/ground ring (may generate unsolvable configs).
- Change: In KiteEngine::annotateGloblalGraph(), when routing a full chip,
distinguish three areas: the core (65%), the corona (90%) and the pads
(100%). Capacities on the edges are sets accordingly.
- Change: In RoutingEvent, introduce an alternative algorithm for
conflictSolve1, FindPath which try to deduce the breakpoints from a
truly explorated path. Unfortunatly this gives worst results than the
Cs1Candidates method. The why should be investigated as it's a critical
point in the algorithm.
- Change: In Manipulator::ripupPerpandicular(), when a caged perpandicular
is encountered, instead of just "stopping", rip it up and change is
axis hint (actually increase) it's axis hint so it stands a chance to
go outside the track with an obstacle.
- Change: In RoutingEvent/State::slackenTopology(), allow move up of local
segments when they are tightly constrained *and* blocked (cageds).
Partial modification of functions calls from booleans to flags.
- Bug: In NegociateWindow::NegociateOverlapCost, check for fixed segments
before trying to get DataNegociate. The lack of DataNegociate cause the
TrackElement to be discarted. It's a failsafe behavior, but it leads to
overlaps.
- Bug: In ProtectRoutingPad, in Pad Cells only, *do not* protect RoutingPad
to avoid the edge capacity over the pad to decrease to zero. This is
due to unused RoutingPads being accounted as blockages.

Implementation of pre-routing support (for clock-tree compliance).
* New: In Katabatic, in <AutoContact>, this class is no longer derived
from ExtentionGo. With the simplificated AutoContacts, there is no
reason to do so, and it will save some QuadTree insertions/deletions.
New factory function AutoContact::createFrom(Contact*) which try to
build an AutoContact on top of a Hurricane::Contact. Of course that
base contact *must fit* into one of the predefined Contact
configurations (Terminal, Turn, HTee or VTee).
NOTE: This implies that the pre-routed segments & contacts *are*
correctly articulated, which is not the case when a Cell is read
from disk in "ap" format. The pre-routing feature must be used for
now without any re-read from disk. We will implement a re-articulating
pre-process in the future.
* Change: In Katabatic, in <AutoContact> derived classes, the ::updateCache()
method now display an accurate error message if a segment is connected
but has no AutoSegment conterpart (i.e. the lookup fails).
* New: In Katabatic, in <AutoSegment>, the ::computeOptimal() method is
short-circuited for pre-routed segments, the optimal axis position is
considered to be the one it is currently on (i.e. we trust the designer).
* New: In Katabatic, in <KatabaticEngine>, the ::loadGlobalRouting()
method now accept a map of excluded nets (same as Knik). This map is
the one of pre-routed nets.
* New: In Katabatic, in layer assignment, do not try to displace fixed
segments...
* New: In Katabatic, in <AutoSegment>, new flag SegUserDefined and related
methods to know if a segment comes from the global router (Knik) or
is pre-routed (supplied by the user).
* New: In Kite, In <BuildPowerRails>, support (exclusion) for pre-routed
nets.
* New: In Kite, In <GraphicKiteEngine> new menu entry for running the
router on pre-routed nets ("Detailed Pre-Route"), also integrated
in the all-on-one route command.
* New: In Kite, In KiteEngine, new method ::_initDataBase() that group
all the initialisation steps. It is a mix of calls between Knik and
Kite initializations which are intertwinneds (may have to devellop
a shared common base at a later point). It creates the Knik grid,
then the Katabatic grid, then load pre-routed wires and power rails
and protect isolated RoutingPads.
Add support for a map of pre-routed nets (to be excluded for
Knik calls).
The method "::run()" now uses function flags, firstly to know if
it is managing pre-routed wires or general purposes ones.
* New: In Kite, in <NegociateWindow>, the "::run()" methods has now two
modes. The normal one and the 'KtPreRoutedStage' that is for routing
pre-routed nets. When in pre-route stage, the wires are fixed at the
end of this step.
* New: In Kite, in <TrackElement> add decorator for AutoSegment
isUsedDefined().
* New: In Kite, in <TrackSegment>, the various ::canDogleg() methods
returns false for a pre-routed (user-defined segment).
* New: In Kite, in PyKiteEngine, added new method runNegociatePreRouted().

- Bug: In BuildPowerRails, uses stable_sort<> instead of sort<>, which
causes unexplained core dumps (seems to try to perform a comparison
using the "end" pseudo element). Already occured in Knik, no explanation
other than a STL bug.
- Change: Slight changes in the weights to move up. Now needs a full empty
track instead of a half one.

* ./kite:
- Change: Propagate renaming "obstacle" -> "blockage".
- Bug/Change: In Configuration, the value of the extensionCap was too big
(1.5 lambda), reduce to 0.5 lambda. This is a problem, the extension
should be coupled to the layer as it is not the same for each METAL.
- Bug: When using TrackElement, always uses the virtual "->isFixed()" method
instead of trying to access to "->base()->isFixed()" as the base may be
NULL in case of blockage/fixed segment.
- Change: Merge PowerRails & Blockage trans-hierarchical construction (into
PowerRails). All blockages are groupeds under "blockagenet".
Allows to remove TrackBlockage & BuildBlockages.
- Change: In KiteEngine::annotateGloblalGraph(), when routing a full chip,
ring power segments around the core must completly saturate the edges
in their segment direction. This is to prevent the global router to
use paths under the power/ground ring (may generate unsolvable configs).
- Change: In KiteEngine::annotateGloblalGraph(), when routing a full chip,
distinguish three areas: the core (65%), the corona (90%) and the pads
(100%). Capacities on the edges are sets accordingly.
- Change: In RoutingEvent, introduce an alternative algorithm for
conflictSolve1, FindPath which try to deduce the breakpoints from a
truly explorated path. Unfortunatly this gives worst results than the
Cs1Candidates method. The why should be investigated as it's a critical
point in the algorithm.
- Change: In Manipulator::ripupPerpandicular(), when a caged perpandicular
is encountered, instead of just "stopping", rip it up and change is
axis hint (actually increase) it's axis hint so it stands a chance to
go outside the track with an obstacle.
- Change: In RoutingEvent/State::slackenTopology(), allow move up of local
segments when they are tightly constrained *and* blocked (cageds).
Partial modification of functions calls from booleans to flags.
- Bug: In NegociateWindow::NegociateOverlapCost, check for fixed segments
before trying to get DataNegociate. The lack of DataNegociate cause the
TrackElement to be discarted. It's a failsafe behavior, but it leads to
overlaps.
- Bug: In ProtectRoutingPad, in Pad Cells only, *do not* protect RoutingPad
to avoid the edge capacity over the pad to decrease to zero. This is
due to unused RoutingPads being accounted as blockages.

* ./kite:
- New: In BuilPowerRails & BuildBlockage, specific support for chip-level
design. The Alliance "top chip" design hierarchical structure is
hard-coded. Top level POWER/GROUND/CLOCK nets must always have the
<vsse>, <vdde>, <ck>, <vssi>, <vddi>, <ckc>, <cki> names.
Specific method to get trans-hierarchical root nets, espcially in
case of global ones (POWER/GROUND). Clock is *not* global.
Some correction in the manner obscured tracks are computeds.
- New: ProtectRoutingPad module that perform a more clean work for protecting
unused RoutingPad.

ExtensionCap support and source/target terminal flags in Katabatic & Kite.
Placement management:
* Change: In <metis>, always disable the hMetis support regardless of
it being detected or not as the placer is still unable manage the
final bin contents.
Routing gauge management:
* Bug: In CRL Core, <vsclib/alliance.conf>, set the correct pitches and
size for the routing layers and the cell gauge.
* Change: In Katabatic & Kite, extract the correct extension cap for each
routing layer from the layers characteristics (cache then in
Katabatic::Configuration).
* Change: In Katabatic, <AutoSegment>, create segment with the wire width
defined in the gauge. For AutoSegment created on already existing
Segment from the global routing, adjust the width.
* Change: In Katabatic, <AutoSegment>, more accurate information about how
a segment is connected to terminal via source and/or target.
The flag SegStrongTerminal is splitted into SegSourceTerminal and
SegSourceTarget (but still used as a mask). So now we can know by
which end an AutoSegment is connected to a terminal.
* Change: In Katabatic, ::doRp_Access(), create constraint freeing segments
not only when HSmall but also when VSmall (more critical for <vsclib>).
Otherwise we may see AutoSegments with incompatible source/target
constraints.
* Change: In Kite, BuildPowerRails, do not create blockage on PinOnly
layers *but* still create power rails planes. This is a temporary
workaround for <vsclib> where the METAL1 blockages overlaps the
terminals (it was fine for Nero, but they shouldn't for Kite).
* Change: In Kite, <RoutingEvent>, if a TrackSegment is overconstrained,
directly bybass it's slackening state to DataNegociate::Slacken.
Also rename the flag "_canHandleConstraints" to "_overConstrained",
seems clearer to me.
Miscellaneous:
* Change: In CRL Core, <Utilities>, add a "pass-though" capability on the
mstream to temporarily make them print everything.

Support of RoutingGauge, part 2.
In Katabatic & Kite, remove all hard-coded values related to track pitches.
* New: In <Session>, add more convenience function to access RoutingGauge
characteristics.
* New: In <AutoSegment>, <AutoContact>, add support for the "depth spin",
that is, if the source/target contacts are going "top" or "down".
Used to compute the perpandicular pitch. Need a small modification
of the revalidation mechanism. The observers of <AutoSegment> are
notified when the spin changes.
* New: In <AutoSegment>, the getPPitch() method allow to compute the
"perpandicular pitch". For now it is simply the greatest from the
source perpandicular pitch and the target perpandicular pitch.
Make uses of the "depth spin".
* New: In <TrackElement>, <TrackSegment>, cache the perpandicular pitch.

Improved UpdateSession & exception catching. Start of RoutingGauge implem.
Miscellaneous:
* Change: In <crlcore>, in display.conf use the same display threshold
for both METAL2 & METAL3.
In alliance.conf, the side of VIAs in the gauge is 2l (not 3l).
In kite.conf, separate edge densities for H/V.
* Change: In <Cell>, in flattenNets() use flag as argument, not a
boolean. Do not create rings for clock or supply nets.
* Change: In <DeepNet>, in _createRoutingPads() do not create rings
for clock or supply net (duplicated policy as in Cell::flattenNets()).
* Bug: In <ControllerWidget>, at last find the bad signal disconnect
that was causing ungraceful messages.
* Change: In <knik>, in Edge display occupancy/capacity in the string
name. Improved display progress and debugging capabilities.
Improved exception catch & breakpoint managment:
* Bug: In <PaletteWidget>, in updateExtensions() replace the calls to
deleteLayer() by delete. This cause the widget to be immediatly
erased instead of waiting for the event queue to be completly
processed. This was causing the widget to be left in a incoherent
state when stoping at a breakpoint.
* Bug: In <BreakpointWidget>, in execNoModal(), flush the main event
loop (QApplication::flush()) *before* lauching the *local* event
loop. This is to ensure all widgets are in their final state when
waiting (especially <PaletteWidget>).
* Change: In <ExceptionWidget>, new method catchAllWrapper() to
execute any std::function< void() > function/method with a "try"/
"catch" wraparound and lauch the widget in case something is catch.
* New: In <hurricane>, support for a oberver pattern, backported from
<katabatic> with an Obervable capable of being linked to any
number of Obervers.
* New: In <Cell>, made it observable to detect Cell change, currently
emit two kind of signals:
- Cell::CellAboutToChange : *before* any change.
- Cell::CellChanged : *after* the change has been completed.
* New: In <UpdateSession>, in Go::invalidate() add the Cell owning the
Go to the UPDATOR_STACK (of course the cell is added only once).
In addition, when the Cell is added, send a notification of
Cell::CellAboutToChange to all it's observers. The slave instances
are also invalidated.
Conversely in UpdateSession::_preDestroy() for each invalidated
Cell send a Cell::CellChanged notification to all observer.
The UPDATOR_STACK has been slightly amended to accept Cell which
are not Gos. Prior to this, the Cell where completly excluded from
the UpdateSession mechanism, so it's instances where never actualised
of anything referring to the Cell for that matter.
Note: we use two different mechanisms to transmit a Cell change,
observers and the slave instance map. I think at some point it
should be unificated.
* Change: In <CellViewer>, make it a Cell observer to redraw when the
cell is modificated (also update the palette).
Uses the catchAllWrapper() to protect all critical actions.
* Change: In <GraphicTool>, no longer need of cellPreModificated and
cellPostModificated signals. Now done through the Cell obersvers.
* Change: In <mauka>, <etesian> & <kite> now uses the catchAllWrapper
method for protection (need to split methods in two, to be able
to pass it as argument). No longer emit cellPreModificated and
cellPostModificated.
Support for RoutingGauge in P&R:
* Bug: In <placeandroute.py>, the connection from the internal power
ring to the connectors was not done correctly. Wrong contact layers
leading to a gap.
* Change: In <BuildPowerRails>, detection of the corona signals based
on how the "pck_px" pad is connected. No longer based on name
matching.
* Change: In <placeandroute.py>, support for 2 routing metal only
(3 metal in the technology).
* Change: In <katabatic> & <kite> support for a "top layer" limitation
on the routing gauge, this allows to use only two routing metals
(METAL2 & METAL3). Work in progress.

are also invalidated.
Conversely in UpdateSession::_preDestroy() for each invalidated
Cell send a Cell::CellChanged notification to all observer.
The UPDATOR_STACK has been slightly amended to accept Cell which
are not Gos. Prior to this, the Cell where completly excluded from
the UpdateSession mechanism, so it's instances where never actualised
of anything referring to the Cell for that matter.
Note: we use two different mechanisms to transmit a Cell change,
observers and the slave instance map. I think at some point it
should be unificated.
* Change: In <CellViewer>, make it a Cell observer to redraw when the
cell is modificated (also update the palette).
Uses the catchAllWrapper() to protect all critical actions.
* Change: In <GraphicTool>, no longer need of cellPreModificated and
cellPostModificated signals. Now done through the Cell obersvers.
* Change: In <mauka>, <etesian> & <kite> now uses the catchAllWrapper
method for protection (need to split methods in two, to be able
to pass it as argument). No longer emit cellPreModificated and
cellPostModificated.
Support for RoutingGauge in P&R:
* Bug: In <placeandroute.py>, the connection from the internal power
ring to the connectors was not done correctly. Wrong contact layers
leading to a gap.
* Change: In <BuildPowerRails>, detection of the corona signals based
on how the "pck_px" pad is connected. No longer based on name
matching.
* Change: In <placeandroute.py>, support for 2 routing metal only
(3 metal in the technology).
* Change: In <katabatic> & <kite> support for a "top layer" limitation
on the routing gauge, this allows to use only two routing metals
(METAL2 & METAL3). Work in progress.

Implementation of pre-routing support (for clock-tree compliance).
* New: In Katabatic, in <AutoContact>, this class is no longer derived
from ExtentionGo. With the simplificated AutoContacts, there is no
reason to do so, and it will save some QuadTree insertions/deletions.
New factory function AutoContact::createFrom(Contact*) which try to
build an AutoContact on top of a Hurricane::Contact. Of course that
base contact *must fit* into one of the predefined Contact
configurations (Terminal, Turn, HTee or VTee).
NOTE: This implies that the pre-routed segments & contacts *are*
correctly articulated, which is not the case when a Cell is read
from disk in "ap" format. The pre-routing feature must be used for
now without any re-read from disk. We will implement a re-articulating
pre-process in the future.
* Change: In Katabatic, in <AutoContact> derived classes, the ::updateCache()
method now display an accurate error message if a segment is connected
but has no AutoSegment conterpart (i.e. the lookup fails).
* New: In Katabatic, in <AutoSegment>, the ::computeOptimal() method is
short-circuited for pre-routed segments, the optimal axis position is
considered to be the one it is currently on (i.e. we trust the designer).
* New: In Katabatic, in <KatabaticEngine>, the ::loadGlobalRouting()
method now accept a map of excluded nets (same as Knik). This map is
the one of pre-routed nets.
* New: In Katabatic, in layer assignment, do not try to displace fixed
segments...
* New: In Katabatic, in <AutoSegment>, new flag SegUserDefined and related
methods to know if a segment comes from the global router (Knik) or
is pre-routed (supplied by the user).
* New: In Kite, In <BuildPowerRails>, support (exclusion) for pre-routed
nets.
* New: In Kite, In <GraphicKiteEngine> new menu entry for running the
router on pre-routed nets ("Detailed Pre-Route"), also integrated
in the all-on-one route command.
* New: In Kite, In KiteEngine, new method ::_initDataBase() that group
all the initialisation steps. It is a mix of calls between Knik and
Kite initializations which are intertwinneds (may have to devellop
a shared common base at a later point). It creates the Knik grid,
then the Katabatic grid, then load pre-routed wires and power rails
and protect isolated RoutingPads.
Add support for a map of pre-routed nets (to be excluded for
Knik calls).
The method "::run()" now uses function flags, firstly to know if
it is managing pre-routed wires or general purposes ones.
* New: In Kite, in <NegociateWindow>, the "::run()" methods has now two
modes. The normal one and the 'KtPreRoutedStage' that is for routing
pre-routed nets. When in pre-route stage, the wires are fixed at the
end of this step.
* New: In Kite, in <TrackElement> add decorator for AutoSegment
isUsedDefined().
* New: In Kite, in <TrackSegment>, the various ::canDogleg() methods
returns false for a pre-routed (user-defined segment).
* New: In Kite, in PyKiteEngine, added new method runNegociatePreRouted().

Add NetRoutingState (Property) on Nets to tell Kite what to do.
* New: In Katabatic, add the ability to decorate some (i.e. few) nets
with a state that indicate to Katabatic & Kite what to do with it.
The possible states are:
1. Fixed : all the wire are in fixed positions. The router cannot
move them and account them as obstacles.
2. ManualGlobalRoute : a user-defined topology is supplied. The
wires still have to be detailed route in "Detailed Pre-Route"
but will be skipped for the global routing and fixed for the
general Detailed route.
3. AutomaticGlobalRoute : ordinary nets, to be global routed then
detail routed.
4. Excluded : do not try to global or detail route thoses nets.
5. MixedPreRoute : mask combining Fixed and ManualGlobalRoute.
Not all nets have this property, only those that needs a special
processing.
To ease the access to the state, it is nested inside a
PrivateProperty in the net (NetRoutingProperty), with an extension
access class (NetRoutingExtension).
* New: In Kite, take account of NetRoutingState. Pointers to the
net's states are strored inside an internal map for faster access.
The property is *not* deleted when Kite is destroyed. The property
will remains until the Net itself is destroyed.
As a consequence, the lists that where passed to high level
function are removed as the information can now be accessed directly
through the net NetRoutingProperty.
* New: In Unicorn, in CgtMain, comply with the update interface.
* New: In documentation, update the User's Guide to explain the Pre-routed
step of Kite.

Express "xEdgeCapacity" ratio as "xTracksReservedLocal" a number of tracks.
* Change: In Kite, Katabatic & Knik, express the number of tracks truly
available to the global router by the number of tracks reserved to
the local routage inside a GCell. Replace the ratio parameter
"hEdgeCapacity" by an integer parameter "hTracksReservedLocal"
(duplicate for verticals).
It is more explicit to give directly the number of tracks that
are to be used locally, and potentially saves us from rouding
problems when calculating the number of availables tracks.
Note: we cannot do that for the layer saturateRatio as it
uses the density ratio that take account local wires, leading
to fractional results.
* Change: In Katabatic, in <GCellGrid>, rename checkEdgeSaturation()
into checkEdgeOverflow(), more explicit.
* Change: In Knik, in <Graph>, display the computed capacities of the
lower left node edges (should be the same througout all the grid).
* Change: In Unicorn, in <cgt.py>, uses the new parameters names for
edge density.

Support of RoutingGauge, part 2.

characteristics.
* New: In <AutoSegment>, <AutoContact>, add support for the "depth spin",
that is, if the source/target contacts are going "top" or "down".
Used to compute the perpandicular pitch. Need a small modification
of the revalidation mechanism. The observers of <AutoSegment> are
notified when the spin changes.
* New: In <AutoSegment>, the getPPitch() method allow to compute the
"perpandicular pitch". For now it is simply the greatest from the
source perpandicular pitch and the target perpandicular pitch.
Make uses of the "depth spin".
* New: In <TrackElement>, <TrackSegment>, cache the perpandicular pitch.

Support of RoutingGauge, part 2.
In Katabatic & Kite, remove all hard-coded values related to track pitches.
* New: In <Session>, add more convenience function to access RoutingGauge
characteristics.
* New: In <AutoSegment>, <AutoContact>, add support for the "depth spin",
that is, if the source/target contacts are going "top" or "down".
Used to compute the perpandicular pitch. Need a small modification
of the revalidation mechanism. The observers of <AutoSegment> are
notified when the spin changes.
* New: In <AutoSegment>, the getPPitch() method allow to compute the
"perpandicular pitch". For now it is simply the greatest from the
source perpandicular pitch and the target perpandicular pitch.
Make uses of the "depth spin".
* New: In <TrackElement>, <TrackSegment>, cache the perpandicular pitch.
Updated through the notification from the observable.

* ./kite:
- New: In NegociateWindow/RoutingEvent, adds a more comprehensive stage
"Repair". Perform in three stage: first try to place with a relaxed
constraint (one GCell on each side). Second try to minimize the faulty
segment. Third perform another "repack perpandicular" but this time
the faulty segment is re-inserted *before* any of it's perpandiculars.
- New: In RoutingEvent::cacheAxisHint(), when a segment has a parent, that
is comes for a "moveUp()", uses the parent axis hint as it's own.
- New: In State::slackenTopology(), in the global FSM, adds a special
operation when reaching MaximumSlack: forceOverLocals(), try to insert
the global on track containing only local segments. Should tend to
concentrate locals on a small set of shared tracks. Most useful on the
highest layers.
- New: In State::slackenTopology(), in the "MoveUp" state, try to find the
more appropriate segment to move up (Manipulator::desaturate()).
Effectively move up the longest segment fully enclosing the one we are
processing.
- New: In State::slackenTopology(), add a check for fully blocked segments
in the local segment FSM. Calls State::solveFullBlocked().
- New: In KiteEngine::createGlobalGraph(), decrease the vertical capacity
of one track inside the core. Helps smooth the vertical density.
- Change: In Manipulator::insertInTrack(), when a track is freed for a
to be inserted changes the priorities so that the segment is immediatly
inserted. Parallels ripeds and theirs perpandiculars are replaced
only *after*. This is the opposite of the previous behavior.
- Change: In NegociateWindow::NegociateOverlapCost(), account the costs
of terminals only for deep depth layers (M1, M2 & M3).
- Change: In RoutingEvent::insertInTrack(), expand the excluded interval
by a half-pitch (2.5l) instead of one lambda.
- Change: In State::State(), do not uses DiscardGlobal if the ripup count
exceed 5. Case of the "Strap" segments that can be ripped a lot
before changing state.
- Change: In State::_processNegociate(), no longer lock into position
(fixed) the local terminal segments as a last resort.
- Change: In RoutingEvent::_processNegociate(), no longer ripup perpandiculars
when a segment is inserted in a free space. Reduce the number of
events whithout degrading the routing quality.
- Change: In State::conflictSolve1_v1b(), if getLongestConflict() is nul,
ignore the track, the conflict must occurs on another track.
- Change: In TrackCost, add a flag support. First uses, a flags to prevent
a local of the topmost layer to ripup a global which is in moveUp
state.
- Bug: In State::solveFullBlockage(), after have been freed, reset the
segment state to "moveUp".
- Bug: In manipulator::minimize(), the axisHint was miscalculated if the
punctual span was empty.

* ./Kite:
- New: In BuildPowerRails, special processing for the power ring segments.
The "diagonal" of vias at each corner is causing a misbehavior of the
routing algorithm (due to fully saturated GCells in one direction).
As a temporary fix, extend the segments so they form a "square corner".
(problem arise on "d_in_i(22)").
- New: In RoutingEvent::_processNegociate, disable the "isForcedToHint()"
feature. No noticeable loss of quality or speed.
- New: In TrackElement/TrackSegment, wraps the AutoSegment parent's mechanism.
Allows to gets the DataNegociate of either the segment or it's parent.
- New: State::solveFullBlockages(), dedicated method to solves the case when
all the allowed tracks of a segment are blocked, tries to moves up
local segments and to break-up global ones.
- New: RoutingEventLoop, a more sophisticated way to detect looping.
Maintain a dynamic histogram of the last N (default 10) segments routeds,
with the count of how many times they have occurred. If that count
exeed 40, we *may* be facing a loop.
- Change: In State::conflictSolve1, implement new policy. The global segments
no more can be broken by local ones. The idea behind is that breaking
a global on the request of a local will only produce more cluttering
in the GCell. Globals must be keep straigth pass through, especially
inside near-saturated GCells. Globals breaking however can occurs at
another global's request.
- Change: In TrackCost, implement the new policy about locals segments that
cannot break globals segments. The sorting class now accept flags to
modulate the sorting function. Two options avalaibles: IgnoreAxisWeigth
(to uses for strap segments) and DiscardGlobals (to uses with locals).
- Change: In TrackCost, the "distance to fixed" have now an upper bound of
50 lambdas (no need to be greater because it means it's outside the
begin & en GCells). Take account not only of fixed segment, but also
of placed segments which makes bound.
- Bug: In Track::_check(), while calling each individual TrackSegment check,
uses it as the *first* argument of the "or", otherwise it may not be
called.
- Bug: In ProtectRoutingPad, loop over segment Collections while modificating
it was producing non-deterministic results. The fact that a collection
must be not modificated while beeing iterated is becoming a more and more
painful problem.

* ./Kite:
- New: In BuildPowerRails, special processing for the power ring segments.
The "diagonal" of vias at each corner is causing a misbehavior of the
routing algorithm (due to fully saturated GCells in one direction).
As a temporary fix, extend the segments so they form a "square corner".
(problem arise on "d_in_i(22)").
- New: In RoutingEvent::_processNegociate, disable the "isForcedToHint()"
feature. No noticeable loss of quality or speed.
- New: In TrackElement/TrackSegment, wraps the AutoSegment parent's mechanism.
Allows to gets the DataNegociate of either the segment or it's parent.
- New: State::solveFullBlockages(), dedicated method to solves the case when
all the allowed tracks of a segment are blocked, tries to moves up
local segments and to break-up global ones.
- New: RoutingEventLoop, a more sophisticated way to detect looping.
Maintain a dynamic histogram of the last N (default 10) segments routeds,
with the count of how many times they have occurred. If that count
exeed 40, we *may* be facing a loop.
- Change: In State::conflictSolve1, implement new policy. The global segments
no more can be broken by local ones. The idea behind is that breaking
a global on the request of a local will only produce more cluttering
in the GCell. Globals must be keep straigth pass through, especially
inside near-saturated GCells. Globals breaking however can occurs at
another global's request.
- Change: In TrackCost, implement the new policy about locals segments that
cannot break globals segments. The sorting class now accept flags to
modulate the sorting function. Two options avalaibles: IgnoreAxisWeigth
(to uses for strap segments) and DiscardGlobals (to uses with locals).
- Change: In TrackCost, the "distance to fixed" have now an upper bound of
50 lambdas (no need to be greater because it means it's outside the
begin & en GCells). Take account not only of fixed segment, but also
of placed segments which makes bound.
- Bug: In Track::_check(), while calling each individual TrackSegment check,
uses it as the *first* argument of the "or", otherwise it may not be
called.
- Bug: In ProtectRoutingPad, loop over segment Collections while modificating
it was producing non-deterministic results. The fact that a collection
must be not modificated while beeing iterated is becoming a more and more
painful problem.
