* Change: In Hurricane, in Flags add operator overload for "int" type
and not only "unsigned int". Otherwise the compiler complaints about
ambiguous overload when using enum values which are considered as
"int".
Simpler code for the BaseFlags::contains() method.
Added implicit conversion from BaseFlags toward bool type.
* Change: In Hurricane, in Commons, complete replacement of the previous
two trace systems (trace & ltrace) by a stream-based one.
As it is a true object it is much less fragile than the one based
on defines (but maybe a little slower).
Define a reservation table for the trace levels for all the
Coriolis & Chams components.
* Change: All tools, use the new trace system.
* 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.
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.
- Bug: In Cs1Candidate::consolidate(), the loop on the conflicting segment was
going one step to far. "i" must be bound to _conflicts.size()-1.
- Change: kite-text is renamed into kite.bin. It features the router only
with a subset of options consistent with cgt (python). Mainly used for
debugging purposes (gdb, valgrind, ...).
- Change: Big cleanup. Supress all the GCell level: GCell, GCellGrid,
GCellRoutingSet. Blockages now managed inside the BuildPower.
- New: In NegociateWindow, Histogram of GCell densities in Gnuplot
format.
./metis,

./kite :
- Change: switch toward the XML configuration system. Suppress the need
of a default static configuration (now built on demand from the XML
database).
In Mauka and Kite, suppress the ConfigurationWidget, wich are
obsoleted by the generic XML configuration widget.
- Bug: In CMakeLists.txt, local include directories *first*.
- Change: In Configuration::setRipupLimit(), swap the two parameters,
more natural ordering.
- New: In ConfigurationWidget, adds an "apply" button to register the
new parameters values.
- Change: In Configuration, sets the default expandStep parameter to
0.99 (gives better results).
- Change: In KiteEngine::_computeCagedConstraints(), detect and build
a list of segments on which caged constraints are incompatibles
(tearing effect shown in ieee_division). All caged constraints
functions are modificated accordingly.
- Change: In Session::_revalidate(), makes doglegs on Segment with
incompatible caged constraints.
- Mark: vld & ieee_division works.
- Bug: In top CMakeLists.txt the SETUP_PROJECT_PATHS was not inserting
X_USER_TOP *before* X_TOP, thus potentially allowing an obsolete
system-wide configuration to shadow an up-to-date local one.
* ./kite:
- Change: In Configuration/KiteEngine, propagate changes in Configuration
in Kite. Note that a *second* singleton is created at Kite level.
- New: KiteEngine::printConfiguration() method to allow quick checks of
the router's main parameters.
- New: ConfigurationWidget to display/sets all the revelant Katabatic/
Kite configuration parameters. To be used with the TabSettings from
the ControllerWidget.
The ConfigurationWidget is bound to the default (static) Kite
configuration, as once it has been run you obviously cannot change the
router's settings.

No more "coriolis/src".
