* New: Equipotential elements includes now:
1. Components at the top level (the cell owning the Equi).
2. Nets at the top level. If an equi include all the components
of a Net, own the Net, not all it's individual components.
3. Other equipotentials from the Instances immediatey below.
Thoses equis should be equivalents to the Plug of the Net.
They are stored in the form of Occurrences <Instance,Equi>,
the relation is stored on that Occurrence.
* New: Equipotential::getFlatComponents(), a collection to recursively
get all the *component* occurrences of the equi. Transhierarchically.
Go through components, nets components, and recursively through
the child equis.
* New: EquipotentialRelation, the master of this relation is the
Equipotential and the slaves, all its elements.
* Change: In Tile, in case the tile is build on a deep component,
we trace up the Equipotential it belongs to in the Instance
level immediately belonging to the Cell under extraction.
They must exists as we extract from bottom to top all the
master cells. So we have, for that tile an Occurrence
<Instance,Equi> that we can store in the current Equi level.
* Change/Bug: In Tile, add an Id to be reliably sort the tiles
in the IntervalTree. As we replaced the tile component occurrence
by a <Instance,Equi> we were having multiple tiles with the same
equi. This was causing havoc again in the IntervalTree.
Should add a check in the RbTree for elements with the
exact same key, but that would imply passing a new template
parameter for the "equal" function.
* Bug: In Interval::intersect(), bad condition check in strict mode.
* Change: In Occurrence::operator<(), change the sorting criterions
so that the ones with no paths are "lower", then the one with
no entities, then compare entities Id then Path hashes.
* Change: In Occurrence::getCompactString(), to be more readable,
suppress leading and ending "<>".
* Change: In IntervalTree, now use an IntervalDataCompare to control
the ordering of the nodes inside the tree. This may be needed
when IntervalData is build upon a pointer, we don't want to
sort on pointer values (non deterministic) .
* Bug: In IntervalTree::postRemove(), there was an incorrect computation
of the updated childsVMax.
* Bug: In IntervalTree::beginOverlaps(), miscalculated leftmost
interval overlapping.
* Bug: In RbTree::remove(), when exchanging the removed node for a
leaf, fully swap the nodes contents, was incompletly copied before.
* New: In CellWidget, add new slots selectSet(OccurrenceSet&) and
unselectSet(OccurrenceSet&), to be able to select/unselected sets
of Occurrence (for use by TabEquipotentials).
* Change: In EtesianEngine, no more need to remove leading/ending "<>".
* New: In Tramontana, use a Query to find all the Occurrence under
an area. Previously we were using Cell::getOccurrencesUnder()
which *do not* return the components in instances, so we would
have been unable to find trans-hierarchical shorts circuits.
* New: In tramontana, now use a Relation to tag all the components
belonging to an Equipotential.
* Change: In Equipotential, store everything under the form of
Occurrence, instead of Components. Due to the way the Occurrences
are sorted, the one holding Components should be firts.
* New: In Tramontana,
* Multi-layer support for the swap line. Split VIAs into their
various metal plates and link the two relevant tiles, ensuring
connexity between layers.
* Improved Equipotential information rebuild. Try to rebuild more
closely the Net characteristics. Improved tab widgets.
* New: Tramontana::Equipotential, implemented.
* Change: Tramontana::Tile, add UnionFind capabilities and Equipotential
attribute.
* New: Tramontana::SweepLine, build upon Hurricane::IntervalTree,
can now perform a "one layer only" extraction (checked with "metal1").
