* ./katabatic: - Change: In loadGlobalRouting(), more exlicit message as to why a net is filtered out the routing set (POWER, GROUND, CLOCK or BLOCKAGE). - New: ChipTool, module with utilities specific to chip routing. Containing a function to pre-break wires around a block. - New: In loadGlobalRouting/GCellConfiguration, adds supports for RoutingPad connected on chip's pad. - New: In GCellGrid/GCell, can compute the density in three modes: average, max of H/V and max of layer. Currently implemented in getMaxHVDensity(), should be unificated with getDensity(). Used for display purposes. - Bug: In AutoContact, when splitting a contact, add a specific check for "one layer span". - Bug: In AutoSegment::canMoveUp(), do not move up fixed segments.

* ./katabatic: - 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.

* ./katabatic: - 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.
