* New: In Anabatic_AutoSegments collection, added a Flag to the constructors
to allow different behavior between digital and analog modes.
For "Aligneds" and "Perpandiculars" collections, now manage a new
Flag WithDoglegs to follow aligned globals through local doglegs
(for analog nets).
Adjust the log level of collections to 144 (formerly 145).
* New: In Anabatic::AutoSegment, new flag SegAnalog for segments that are
part of an analog net.
Note that with this flag, we reach the 32 bits limit...
* Change: In Anabatic::Constants, Flags are now declared as BaseFlags
objects and *not* uint64_t. This avoids overload resolution problems with
arithmetical overload of the operators.
The BaseFlags/Flags types are now completly "isolated" from the
uint64_t, it has the advantage of showing where unwanted previous implicit
conversions where occuring.
* Change: In Katana::Constants, Flags values are now of BaseFlags type instead
of uint64_t.
* Change: In Anabatic::Dijkstra, lots of log cleanup.
* Change: In Anabatic::GCell::getSide(), make the "shrink" parameter visible
to allow to substract the topmost and rightmost track for axis span
computation in AutoSegment::computeOptimal(). Used for analog mode.
* Change: In NetRoutingState, added a flag for analog mode. Use uint32_t
for the flags type.
* New: In Isobar, export the NetRoutingState and NetRoutingExtension objects.
* Change: In Anabatic::AutoSegments collections, change the type of all
the flags that where in "unsigned int" (32 bits) to Flags (uint64_t)
as there is now more than 32 flags for functions.
* New: In Ababatic::Constants, added new flag Flags::WithPerpands, which
makes the number of flags tip over 32 bits, thus making mandatory
to uses Flags and not unsigned int.
* New: In Anabatic::AutoSegments_Perpandiculars, manage a new flag
Flags::WithDoglegs to allow to propagate through global segments that
are connecteds via doglegs on local segments. Meaning that there is
a good chance that they could be aligned.
Slighly change the way we propagate on aligned segments: no longer
check for VTee or HTee, but only for same direction and layer as
master.
* New: In Anabatic & Katana, replace all the "int", "long" and their
variants by the less implementation ambiguous "int32_t", "int64_t"
(and variant). This should help to better detect bit trucation in
flags.
Use the type to give a hint about the flags kind:
- Type "Flags", for flags shared among Anabatic & Katana
functions/methods (may also appear in some objects states).
- Type "uint32_t" for flags belonging to an object internal
state of from Hurricane functions flags (those should be
grouped in a Flag subclass in a perfect world).
* Change: In Hurricane::BaseFlags, store flags in uint64_t instead of
unsigned int because we start to need more than 32 different flags
in some tools.
* New: In ::getString() & ::getRecord() templates, add support for
std::array<>.
* Change: In CRL::ToolEngine, add support for timer (time & memory
measurements) displaced from Katabatic. This way all ToolEngine
can use this feature. The _postCreate() method display the
memory just after ToolEngine allocation.
* Change: In Etesian::EtesianEngine, make use of the ToolEngine
builtin timer (remove the local one). Forgot to call the base
class _postCreate() and _preDestroy().
* Change: In Anabatic::AnabaticEngine, make use of the ToolEngine
builtin timer (remove the local one).
* New: In Anabatic, new AutoSegments_Connecteds() collection. This
Collection allows a deterministic walkthough *all* the AutoSegments
connected either to source or target of one AutoSegment.
* New: In Anabatic::AutoContactTerminal::isEndPoint() to check if an
AutoContactTerminal is the *only one* anchored on a RoutingPad,
thus being a true "end point" and not a kind of feed-through.
* New: In Katana::KatanaEngine, added support for symmetric nets.
Created new class DataSymmetric to store symmetric information
of a net (mainly the paired AutoSegments).
Added KatanaEngine::runSymmetricRouter(), for now only build
the DataSymmetric informations. More to come...
* Change: In Katana::GraphicKatanaEngine::_runTest(), now perform
symmetric information building the non-symmetric routing.
* Bug: In Hurricane, in StaticObservable::getObserver(), if the slot
pointer is NULL, do not try to access the owner. Returns NULL, so
the caller can be aware of the situation...
* Change: In Hurricane, in BreakpointWidget & ExceptionWidget some
cosmetic changes (fonts and window sizes).
* Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account
the constraints from the source AutoContact, as it holds the constraints
transmitted by the RoutingPads and sets up by propageConstraintsFromRp().
It is likely to be a bug affecting the original Katabatic as well.
* Change: In Anabatic, in RawGCellsUnder(), check that the segment is not
completly oustside the cell abutment box and truncate the coordinates
to the part that is inside. Use the "shrink" if we reach the east/north
border.
* Change: In Anabatic, in Configuration, no more decorator because we will
use a true derived relationship. Katana *derives* from *Anabatic* and do
not *decorate* it, so the Configuration can do the same. It also implies
that we directly create a Katana engine, not an Anabatic one.
* Change: In Anabatic, in Session, do not allow the opening of the Session
in a standalone fashion (with a static method). Instead it must be opened
using the relevant method of the Anabatic/Katana engine. This ensure we
are opening the right Session type.
* Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment
is not part of the collection by default, but will be included if the
Flags::WithSelf is set.
* Change: In Configuration, all the flags value are now defined in two steps.
Declared in the header and initialized in the module. This is to prevent
the fact that on some cases, in relation with the Python "extern C" part
modules, we need a true allocated variable. It was causing weird linking
problems.
A side effect is that they can no longer be used as entry is switches,
have to replace them by if/else.
* New: In Anabatic, new GCell::getNeighborAt() utility function.
* Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with
the grid type... Back annote all the edges capacity (north & east) with
the reserved local capacity.
* New: Complete portage of Kite over Anabatic. The new engine is christened
"Katana" for Kite-Analogic. When it's capabilities and performances
will be on a part with Kite, it is to completly replace it (and take
back the "Kite" name). Preliminary tests seems to show that, contrary
to intuition (because built on a more complex/slower grid), it is even
slightly faster than Kite 8-).
