In the Cell/Instance hierarchy, the "terminal" and "leaf cell" concepts
where not clearly defined and partially overlapping. Now, "Terminal" is
the refer to the physical hierarchy (layout) and "TerminalNetlist" to
the logical hierarchy (netlist). The logical hierarchy can be less deep
than the physical one thanks to a Cell dedicated cell flags. Collections
related to the physical hierarchy keep their old names, the one related
to the logical hierarchy are renamed from "Leaf" to "TerminalNetlist".
The name "Leaf" was too ambiguous (leaf for *what* hierarchy).
* Change: In Hurricane::Device, set the "TerminalNetlist" flag once and
for all. No need set it in all the derived classes again.
* New: In Hurricane::MultiCapacitor, added new parameter "dummy" to
create dummies around the capacity matrix.
* Change: In Hurricane::Cell, remove "Leaf" related methods, replace
them by "TerminalNetlist" one, especially Collections. Now we have
two clear sets of Collections to walkthough the layout or the
netlist.
Change the "Terminal" flag into "TerminalNetlist".
* Change: In Hurricane::CellCollections, rename "Leaf" into
"TerminalNetlist" collections and apply the new semantic to the
locators.
* Change: In Hurricane::DataBase, Leaf to TerminalInstance renaming.
* Change: In Hurricane::DeepNet, Leaf to TerminalInstance renaming.
* Change: In Hurricane::HyperNet, Leaf to TerminalInstance renaming.
* Change: In Hurricane::Instance, Leaf to TerminalInstance renaming.
* Change: In Hurricane::Viewer::HierarchyInformations, Leaf to
TerminalInstance renaming.
* Change: In CRL::AllianceFramework, Leaf to TerminalInstance renaming.
* Change: In CRL::Catalog, Leaf to TerminalInstance renaming.
* Change: In CRL::ApParser, Leaf to TerminalInstance renaming.
* Change: In EtesianEngine::AddFeeds, Leaf to TerminalInstance renaming.
* Bug: In EtesianEngine::resetPlacement, move there the loop over
non terminal netlist instances to flag fully placed sub-blocks
as terminal for the netlist. Only then remove the feed cells
from unplaced instances. Previously, the feed cells where stripped
even from already placed instances.
* Change: In Katana, Leaf to TerminalInstance renaming.
* Bug: In Bora::PyDSlicingNode, allow the range parameter to be the
Python None object when we do not want to pass one but need to
have it as positional parameter.
* Change: In Cumulus/clocktree/ClockTree.py, Leaf to TerminalInstance
renaming.
* Bug: In Bootstrap, in coriolisEnv.py, check if devtoolset-2 is already
active before launching it as a sub-shell.
* Bug: In Isobar, In PyHurricane.h, DBoDestroyAttribute() set the proxy
pointer toward the C++ object to NULL. So when the Python object is
deleted no double-deletion occurs on the C++ object.
Add some more trace information in Python link/dealloc.
* Change: In CRL Core, in cyclop, make CMakeLists.txt automatically
choose the right rule for linking the binary wether we use Qt 4 or
Qt 5. Very irksome problem.
* New: In EtesianEngine::addFeed(), do not take into account instances
that are not placed entirely inside the top cell abutment box (was
causing a core dump).
* Bug: In Katabatic, in GCellQueue, correct a mismatch between a GCell
set and the iterators used upon it.
* Bug: In Mauka, in Row & Surface correct a mismatch between a container
and it's iterator.
* New: In Etesian, updated to work with the latest Coloquinte, patch
contributed by G. Gouvine.
Added EtesianEngine::setDefaultAb() to compute an abutment box if
the Cell is completly unplaced.
* New: In cumulus, in ClockTree, now the placer can be configured to be
either Mauka (slow simulated annealing) or Etesian (fast analytic).
New setting 'clockTree.placerEngine' in plugin settings.
- Bug: target_link_libraries() must be put back for OSX Snow Leopard
(doesn't seems to affect Leopard). As I do not have an OSX under
my hand it's untested and is likely to fail at that point.
* ./mauka:
- Bug: Place intermediate levels of instances, so that they show up in
the top level.
- Change: New InsertFeeds method + module, sadly we cannot insert the feeds
cells in one merged step with the BBPlacer as the SubRows do not cover
the entire surface due to fixed Cells.
- Change: In doQuadriPart, manage correctly non-square designs. So that
after an initial non-quadripartition step, the partitions are rougly
squares. Seems to have trouble with small designs.
- New: In ConfigurationWidget, add support for hMETIS partitionner.
- New: Static method doQuadriPart() to perform recursive quadri-partionning
of the circuit. Down to the instanceStopCriterion and with metis/nimbus.
Ported from pycoriolis.
- New: MaukaEngine::regroupOverloadedGCells() also imported from pycoriolis.
- New: hMETIS support.
- Change: In Configuration, now CellGauge characteristics are supplied only
through Configuration.
- Change: In SubRow, change the way bin widths are computed.
- Bug: In Surface & MaukaEngine, lengthes that are "proportional" to areas
are now coded with double instead of DbU::Unit, because of capacity
overflow.
