* ./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.

Compliance with Clang 3.4 (RHEL7, MacOS). * New: In Bootstrap, added support for RHEL7 in ccb.py & coriolisEnv.py. In coriolisEnv.py, under RHEL6, directly launch a shell under devtoolset-2 (do not put it in .bashrc). * Change: All tools, compliance with Clang 3.2. - Call using namespace std *after* at least one include of std has been used. - In Utilities.h define both const and non-cont overload for operator<< of mstream (this was the true cause of the Banner display problem). - No longer use defaults arguments in templates, instead create two separated overloads. - Put template static attributes allocation outside of namespaces (this one I'm not sure how to justify). - Protect by NDEBUG variables that are only needed in assert(). - In PyInterval getUnion() & getIntersection() we where silently overwriting the "self" object (interval). - In Mauka, *do no* overload _postCreate() and add an argument, breaks the virtual function mechanism. Rename it into _maukaPostCreate(). Idem for SubRow(). - In Katabatic::GCell(), invalidate() overload a Go funtion but is used for different purpose at this level. Rename it invalidateCt() (invalidate *ConTents*). - Miscellaneous small cleanup.

* ./katabatic: - New: In AutoSegment, adds a "_parent" attribute to keep track of the fragmentation processus. Currently used only for strap segments, points to the original segment in the appropriate direction (before the split). - New: In GCell & LayerAssign, new method of layer assignment. Move up the whole net trunk if only one of it's segment is inside an over-saturated GCell. AutoSegment are moved up only if there is at least 2 free tracks remaining on the upper level. - Change: In Session::_canonize(), uses the lowest segment Id as canonical. More reliable than geometricals criterions in the end. Assuming that the segments are being created in deterministic order, which *should* be the case consediring the way we are walking through the global routing. - Change: In AutoSegment, completly suppress the CompareCanonical(), replace it by the much simpler CompareId(). - Change: In GCell::rpDesaturate(), stops desaturation when bottom density is under 0.5, otherwise we are causing a severe imbalance in M2/M4 densities. All wires pushed up to M4... - Change: In ChipTools, for the Pad's RoutingPad, reslect the best component using the one in the lowest layer. To avoid problem when splitting AutoContact as we expect the base Contact to be on the lower layer. - Bug: In GCellConfiguration::_GCell_xG_xL1_xL3(), add H/V alignement constraints in fork case. This allow NE/SW contact to be splitted correctly later. - Bug: In AutoContact::split(), the connexity on the splitted contacts was not correctly restored, leading to canonization and parentage looping errors. This was concealed by the Kite Track::_check() bug (incomplete individual TrackSegment checking).

* ./katabatic: - New: In AutoSegment, adds a "_parent" attribute to keep track of the fragmentation processus. Currently used only for strap segments, points to the original segment in the appropriate direction (before the split). - New: In GCell & LayerAssign, new method of layer assignment. Move up the whole net trunk if only one of it's segment is inside an over-saturated GCell. AutoSegment are moved up only if there is at least 2 free tracks remaining on the upper level. - Change: In Session::_canonize(), uses the lowest segment Id as canonical. More reliable than geometricals criterions in the end. Assuming that the segments are being created in deterministic order, which *should* be the case consediring the way we are walking through the global routing. - Change: In AutoSegment, completly suppress the CompareCanonical(), replace it by the much simpler CompareId(). - Change: In GCell::rpDesaturate(), stops desaturation when bottom density is under 0.5, otherwise we are causing a severe imbalance in M2/M4 densities. All wires pushed up to M4... - Change: In ChipTools, for the Pad's RoutingPad, reslect the best component using the one in the lowest layer. To avoid problem when splitting AutoContact as we expect the base Contact to be on the lower layer. - Bug: In GCellConfiguration::_GCell_xG_xL1_xL3(), add H/V alignement constraints in fork case. This allow NE/SW contact to be splitted correctly later. - Bug: In AutoContact::split(), the connexity on the splitted contacts was not correctly restored, leading to canonization and parentage looping errors. This was concealed by the Kite Track::_check() bug (incomplete individual TrackSegment checking).

* ./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: - 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.
