- New: In LayerAssignement & GCell, perform layer assignment on whole net
trunk, instead on a segment by segment basis.
- New: In GCell, fragmentation analysis. When a layer change is requested,
it allows to check if the additionnal perpandiculars created to
maintain connexity will not over fragment the layer. This is particu-
larly critical for M3->M5 which create M4 in perpandiculars, and M4
may be subject to very dense configuration.
- New: In AutoSegment & LoadGrByNet, adds a flags telling if the net's
degree equal 2. Has not proven to be useful yet.
- New: In AutoSegment, adds a flag telling if the segment is the perpan-
dicular part of a dogleg. Has not proven useful yet.
- New: ChipTools, regroup all datas and utilities to manage a full-chip
design.
- Change: In LoadGrByNet/GCellConfiguration::_GCell_xG_1Pad(), uses straight
perpandicular wires on top & right pads. The GCells under those connectors
are fully saturated, wires must go out as straight as possible.
- Change: In AutoHorizontal/AutoVertical, update the "terminal" flag after
slackening. This is to avoid global that are no longer connected to
terminals behave as such.
- Change: In AutoSegment::canMoveUp() & canPivotUp(), prevent all local segments
to go up. This is to avoid cluttering upper levels with small segments.
- Change: In GCellConfiguration, for xG_xL3, detect straight vertical topologies
and for them to be fixed (new flag FIXED_GLOBAL set by the topological
builder instead of the constructor). This prevent the router to do
stupid things...
To sets the "Fixed" flag *after* the axis of global segments have been
positionned correctly adds a "_toFixGlobals" static table lookup.
- Change: In GCell::stepDesaturate(), if less than one free track remains in
the upper layer, do not move up the segment. This allows from a minimum
free room for expansion.
- Change: In GCell::_getString(), display indexes and layer names in various
saturation tables.
- Change: In AutoSegment, allow move up of local Segment. ::moveUp() and
::canMoveUp() arguments go from booleans to flags, which are more
explicits.
- Change: In KatabaticEngine, the containers used to store the "nets to
route" is changed from a vector<> to a set<> sorted by the Nets names.
Uses more memory but allows much faster Net deletion.
- New: In _loadNetGlobalRouting(Net*), detect non-routed Nets. A Net is
considered as unrouted if it's 10 first RoutingPads have no slave
Segment. The Net is withdrawn from the set of Nets to route.
- Bug: In GCellConfiguration::_GCell_1G_1L1(), correctly compute the
access flag passed to _GCell_rp_Access().
- Change: In AutoContact::restrictConstraintBox() adds "warnOnError"
parameter to shut down warnings.
- New: KatabaticEngine::_computeNetConstraints() now also returns a set<>
of segments on which constraints are incompatibles. All the NetConstraints
related functions are modificateds accordingly.
- Change: In KatabaticEngine::_loadNetGlobalRouting(), create dogleg
on overconstrained Segments computed by a call to _computeNetConstraints().
Overconstraineds Segments can occurs when a global is directly
connecting two punctual RoutingPads (see "ieee_division").
As a side effect, and to avoid looping each Net is revalidated
*before* making any dogleg. So Nets are revalidated one by one instead
of alltogether.
- Change: In AutoSegment::_toConstraintAxis(), do nothing if constraint
interval is empty.

are at the same level, directly under the root of the repository.
No more "coriolis/src".
