* New: In Hurricane, in Cell & Instance, add the ability to merge the
QuadTree when *second level* instances of a Cell are placed in
the same space as the top Cell. This is the case of a deeply
hierarchical design made of only standard cells that are to
be placed in a "flat" manner.
The design is uniquified then the intermediate instances models,
which should be unique at that point have their QuadTree merged
through a call to Instance::slaveAbutmentBox(). That method will
make the model of the instance use the QuadTree of the Cell to
which the instance belong. The instance model no longer posseses
a dedicated QuadTree. As a corollary the abutment box of both
Cell are kept identical and the Instance has it's transformation
set to (0,0,ID).
Remark: when we talk about "QuadTree", we mean in fact the
QuadTree for the instances *and* the SliceMap (Layer+QuadTree).
Consequence in Query: when going through the resulting
"flattened" QuadTree we will find objects with an incomplete
Path du to the fact that we didn't have to explore their
Instance/Cell level to reach them. The shunted part of the
Path is stored in the Go master Cell in the _shuntedPath
attribute. This also affect the displayed depth of hierarchy,
but not too badly.
* New: In Hurricane, in Cell, new methods:
- Cell::updatePlacedFlag() : set the placement flags.
- Cell::isUnique() : one or less instance.
- Cell::isUniquified() : is the result of an uniquification.
- Cell::isUniquifyMaster() : is the reference cell of the
uniquification.
* Change: In Hurricane, in Cell::Uniquify(), uniquify a Cell only
if it is unplaced. We do not need to duplicate placed Cells
(see datapathes).
* New: In Hurricane, In NetAlias & Net, add an AliasList collection to
iterate over all the aliases names (this *not* include the main
net name).
* New: In Hurricane, In Cell, Instance & Net add support for cloning and
uniquification (update documentation).
All Cells that are uniquified from a given model are kept in an
Uniquify relation. This relation allows to get all the clones and
generate unique clone names by adding a "_uXX" suffix.
* Bug: In Hurricane, the Cell::_isFlattenLeaf attribute was not initialized
in the constructor.
* Change: In CRL Core, in AllianceFramework::getCell(), no longer destroy
a partially loaded Cell in case of parser failure, let the incomplete
Cell be.
* New: In CRL Core, in ApParser, if all the instances are placed, sets the
Cell::Placed flag.
* Change: In CRL Core, in BlifParser, complete rewrite of the parser.
Not so good an idea afterwards...
* New: In Etesian, uniquify the design before placing.
* Change: In Kite, display the list of unrouted wired after all other
statistics.
- New: Added an id on DBo, SharedName and SharedPath to ensure
database determinism. All the hash key now uses the id instead
of the object's pointer (see _getHashValue()).
- Change: In RoutingPad, position is now only relative to the anchor,
no more (dx,dy). Add a isPlacedOccurrence() to check if all the
occurrence in the path are fixed and thus the position meaningful.
* ./hurricane/doc/hurricane:
- Change: In Cell, added doc about PlacementStatus.
- Change: In Transformation, more detailed explanations about the
orientations. A little beautifying too...
- Change: RoutingPad doc update.
- Change: Entity doc update (for id).
- Change: In HTML header/footer uses the new SoC.css.
- A complete sweep of cleanup to suppress allmost all compiler warnings.
* ./hurricane/doc/hurricane:
- New: Documentation cleanup and update, particularly on the new Layer
derived classes.
* ./hurricane/src/hurricane,
./hurricane/src/isobar,
./hurricane/src/viewer:
- New: Creation of new methods, more explicit on DbU. Based on a to/from
naming scheme.
- New: Python support extented to include all objects needed to configure
through python scripts.
- Change: Finally understood what's causing the _XOPEN_SOURCE redefinition.
Basically the Python.h must be included first before any other
include. The type-puned problem will remains still (that is a Python
problem, not our own).
- Change: In DisplayStyle, uses shared_ptr for DrawingStyle instead of
custom made reference count.
