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().

Added support for "same layer" dogleg. Big fix for pad routing.
* Change: In Knik, in Vertex, add a "blocked" flag to signal disabled
vertexes in the grid (must not be used by the global router).
Modificate the Graph::getVertex() method so that when a vertex
is geometrically queried, if is a blocked one, return a non-blocked
neighbor. This mechanism is introduced to, at last, prevent the
global router to go *under* the pad in case of a commplete chip.
* New: In Katabatic, in AutoSegment, a new state has been added: "reduced".
A reduced segment is in the same layer as it's perpandiculars.
To be reduced, a segments has to be connected on source & target to
AutoContactTurn, both of the perpandiculars must be of the same layer
(below or above) and it's length must not exceed one pitch in the
perpandicular direction.
To reduce an AutoSegment, call ::reduce() and to revert the state,
call ::raise(). Two associated predicates are associated:
::canReduce() and ::mustRaise().
Note: No two adjacent segments can be reduced at the same time.
* Bug: In Katabatic, in GCellTopology, add a new method ::doRp_AccessPad()
to connect to the pads. Create wiring, fixed and non managed by
Katabatic, to connect the pad connector layer to the lowest routing
layers (depth 1 & 2). The former implementation was sometimes leading
to gaps (sheared contact) that *must not* occurs during the building
stage.
Remark: This bug did put under the light the fact that the initial
wiring must be created without gaps. Gaps are closed by making doglegs
on contacts. But this mechanism could only work when the database if
fully initialised (the cache is up to date). Otherwise various problems
arise, in the canonization process for example.
* New: In Katabatic, in AutoContactTerminal::getNativeConstraintBox(),
when anchored on a RoutingPad, now take account the potential rotation
of the Path's transformation. Here again, for the chip's pads.
* New: In Kite, support for reduced AutoSegment. TrackSegment associateds
to reduced AutoSegment are *not* inserted into track to become
effectively invisibles. When a segment becomes reduced, a TrackEvent
is generated to remove it. Conversely when it is raised a RoutingEvent
is created/rescheduled to insert it. All this is mostly managed inside
the Session::revalidate() method.
* New: In Kite, in KiteEngine::createGlobalGraph(), in case of a chip,
mark all global routing vertexes (Knik) that are under a pad, as blockeds.
* Bug: In Cumulus, in PadsCorona.Side.getAxis(), inversion between X and
Y coordinate of the chip size. Did not show until a non-square chip
was routed (i.e. our MIPS R3000).
* Change: In Stratus1, in st_placement.py add the ClockBuffer class for
backward compatibility with the MIPS32 bench. Have to review this
functionnality coming from the deprecated placeAndroute.py.
In st_instance.py, no longer creates the Plug ring of a Net.
In my opinion it just clutter the display until the P&R is called.
Can re-enable later as an option (in Unicorn).
* Change: In Unicorn, in cgt.py, more reliable way of loading then running
user supplied scripts. Borrowed from alliance-checker-toolkit doChip.py .

* ./katabatic:
- New: In AutoSegment, adds a "_parent" attribute to keep track of the fragmentation
processus. Currently used only for strap segments, points to the original
segment in the appropriate direction (before the split).
- New: In GCell & LayerAssign, new method of layer assignment. Move up
the whole net trunk if only one of it's segment is inside an over-saturated
GCell. AutoSegment are moved up only if there is at least 2 free tracks
remaining on the upper level.
- Change: In Session::_canonize(), uses the lowest segment Id as canonical.
More reliable than geometricals criterions in the end. Assuming that the
segments are being created in deterministic order, which *should* be the
case consediring the way we are walking through the global routing.
- Change: In AutoSegment, completly suppress the CompareCanonical(), replace
it by the much simpler CompareId().
- Change: In GCell::rpDesaturate(), stops desaturation when bottom density
is under 0.5, otherwise we are causing a severe imbalance in M2/M4
densities. All wires pushed up to M4...
- Change: In ChipTools, for the Pad's RoutingPad, reslect the best component
using the one in the lowest layer. To avoid problem when splitting
AutoContact as we expect the base Contact to be on the lower layer.
- Bug: In GCellConfiguration::_GCell_xG_xL1_xL3(), add H/V alignement constraints
in fork case. This allow NE/SW contact to be splitted correctly later.
- Bug: In AutoContact::split(), the connexity on the splitted contacts was
not correctly restored, leading to canonization and parentage looping
errors. This was concealed by the Kite Track::_check() bug (incomplete
individual TrackSegment checking).

Solve the template lookup problem in tstream.
* Bug: In Hurricane, in tstream (Commons.h), in the *template* overload of
operator<<(), do not use the operator<<() of ostream as it will be
looked up in "stage 1" (template definition) and so will miss all the
overloads added later and built over getString<>(). Instead, make use
of getString<>(), which, as another template will be looked up in
"stage 2" (template instanciation) and at that point will have all the
needed template specialisation of getString<>().
We also need to define new stream manipulators to be able to create
a matching template overload not dependant from the implementation.
To avoid name clashes, we prefix a 't'. For now, only 'tsetw()' is
refined.
As a side effect, we cannot directly print bit-fields into the stream,
we must go through an intermediate variable (happens once in AutoContact).

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().

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.

* 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().

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.

* 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.

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.

More clever way of taking into account constraints on caged terminals.
* Change: In vlsispad, in Dots, add an enable/disable flag because when printing
into a cmess, it is only the base class ostream which is took into account
as none of it's methods are virtuals (silly me).
* Bug: In Etesian, print into cmess instead of cout and make use of the Dots
enabling feature.
* New: In Katabatic, added AutoContact::migrateConstraintBox() to transfert
constraint from one contact to another.
New flag for AutoContact, CntWeakTerminal for AutoContact which are at
the other of a segment directly connected to a terminal. They may hold
special constraints in case of caged terminals (computed in Kite).
In AutoHorizontal & AutoVertical, in ::_makeDogleg(), transfert flags
and constraints when breaking a segment directly connected to a terminal.
* New: In Kite, in protectCagedTerminals(), uses cross constraint on the
AutoContact opposite to the ContactTerminal (CntWeakTerminal) instead
of moving up one terminal over two consecutives. This is simpler without
degrading the routing quality.

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().
