- Bug: During the packaging stage, DESTDIR must be appended to the
pathes prepended to CMAKE_MODULE_PATH.
* ./stratus:
- Bug: In dpgen_RF1.py, small typo for the python executable if the module
is to be run stand-alone. Never show in normal uses.
- Bug: In ROM_encours & dpen_ROM, correct bad indentation.
- New: Install a general index for the HTML documentation.
- Bug: In cyclop CMakeLists, forgot to list all the needed libraries for
the linker.
- New: Support of Python installation layout under Ubuntu 10.04.
lib/python2.6/dist-packages
- New: "debian" directory holding the paraphernalia needed to create a
Debian/Ubuntu package.
- New: In buildCoriolis, add a Debian packaging method.
- Change: In coriolis2.spec, the build/install procedure now makes uses of
the top-level Makefile.
- Change: In FindBoostrap, detection of the distribution type. Finally not
needed but kept here, just in case. Based on "lsb_release".
- Change: In FindPythonSitePackages, simplificate the detection of the Python
site-package directory. No longer on-the-fly generate a python script.
- New: In NegociateWindow/RoutingEvent, adds a more comprehensive stage
"Repair". Perform in three stage: first try to place with a relaxed
constraint (one GCell on each side). Second try to minimize the faulty
segment. Third perform another "repack perpandicular" but this time
the faulty segment is re-inserted *before* any of it's perpandiculars.
- New: In RoutingEvent::cacheAxisHint(), when a segment has a parent, that
is comes for a "moveUp()", uses the parent axis hint as it's own.
- New: In State::slackenTopology(), in the global FSM, adds a special
operation when reaching MaximumSlack: forceOverLocals(), try to insert
the global on track containing only local segments. Should tend to
concentrate locals on a small set of shared tracks. Most useful on the
highest layers.
- New: In State::slackenTopology(), in the "MoveUp" state, try to find the
more appropriate segment to move up (Manipulator::desaturate()).
Effectively move up the longest segment fully enclosing the one we are
processing.
- New: In State::slackenTopology(), add a check for fully blocked segments
in the local segment FSM. Calls State::solveFullBlocked().
- New: In KiteEngine::createGlobalGraph(), decrease the vertical capacity
of one track inside the core. Helps smooth the vertical density.
- Change: In Manipulator::insertInTrack(), when a track is freed for a
to be inserted changes the priorities so that the segment is immediatly
inserted. Parallels ripeds and theirs perpandiculars are replaced
only *after*. This is the opposite of the previous behavior.
- Change: In NegociateWindow::NegociateOverlapCost(), account the costs
of terminals only for deep depth layers (M1, M2 & M3).
- Change: In RoutingEvent::insertInTrack(), expand the excluded interval
by a half-pitch (2.5l) instead of one lambda.
- Change: In State::State(), do not uses DiscardGlobal if the ripup count
exceed 5. Case of the "Strap" segments that can be ripped a lot
before changing state.
- Change: In State::_processNegociate(), no longer lock into position
(fixed) the local terminal segments as a last resort.
- Change: In RoutingEvent::_processNegociate(), no longer ripup perpandiculars
when a segment is inserted in a free space. Reduce the number of
events whithout degrading the routing quality.
- Change: In State::conflictSolve1_v1b(), if getLongestConflict() is nul,
ignore the track, the conflict must occurs on another track.
- Change: In TrackCost, add a flag support. First uses, a flags to prevent
a local of the topmost layer to ripup a global which is in moveUp
state.
- Bug: In State::solveFullBlockage(), after have been freed, reset the
segment state to "moveUp".
- Bug: In manipulator::minimize(), the axisHint was miscalculated if the
punctual span was empty.
- 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.
- Change: In RoutingLayerGauge, no longer throw exception when the position
requested it outside the track grid. Instead returns first/last track
index.
