- New: In Configuration & RoutingEvent, adds support for minimal break length
by layer (METAL1 through METAL7).
- New: Added measures for final detailed wirelength, wirelength expansion ratio,
failed wirelength, number of processeds events and number of unique events.
- New: Parameter "kite.globalMinBreak" (in lambda) telling the minimal size
under wich a global segment will not be broken, used in "conflictSolve1()".
- 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.
- Library linking: there must not be "target_link_library()" for libraries,
only when building binaries. Avoid clashes between static module
or class variables, and strange reinitialisation of those variables.
- Change: Boost is now always linked staticly.
./metis,
./mauka,
./katabatic,
./kite :
- Change: switch toward the XML configuration system. Suppress the need
of a default static configuration (now built on demand from the XML
database).
In Mauka and Kite, suppress the ConfigurationWidget, wich are
obsoleted by the generic XML configuration widget.
- Bug: In CMakeLists.txt, local include directories *first*.
- Change: In Configuration::setRipupLimit(), swap the two parameters,
more natural ordering.
- New: In ConfigurationWidget, adds an "apply" button to register the
new parameters values.
- Change: When static linking is required, also switch Boost libraries in static
mode. Automatically done is modules using FindHURRICANE through
SET_LIB_LINK_MODE(). Note: FindBoost must be called *after* SET_LIB_LINK_MODE().
- New: Adds support to restrict the number of routing layers. Not enabled yet
because the router needs some more tweak if using only two routing layers.
- Change: adopt a tree layout compliant with the UNIX FHS.
* includes under TOP/include/coriolis2.
* shared datas under TOP/shared/coriolis2.
* docs under TOP/share/doc/coriolis2.
* configuration under TOP/etc/coriolis2
* ./crlcore:
- Change: In Environment, comply to the new tree layout, search configuration
files under TOP/etc/coriolis2/.
* ./knik:
- Change: In flute, comply to the new tree layout, get the "POW*.dat" files
from TOP/share/coriolis2/flute-2.4.
libraries gets installed in "lib64" instead of "lib".
buildCoriolis.py sets automatically LIB_SUFFIX for cmake.
coriolis2.spec modificated to uses lib64 on 64 bits.
- Change: In the CMakeLists.txt, in all the install commands remove all
the leading "/" as they prevents the CMAKE_INSTALL_PREFIX to be took
into account. It was nevertheless working because buildCoriolis.py was
using DESTDIR which is prepended anyway.
* ./goodies:
- Change: In buildCoriolis.py, no longer uses the DESTDIR but instead
CMAKE_INSTALL_PREFIX.
- Change: In Configuration, sets the default expandStep parameter to
0.99 (gives better results).
- Change: In KiteEngine::_computeCagedConstraints(), detect and build
a list of segments on which caged constraints are incompatibles
(tearing effect shown in ieee_division). All caged constraints
functions are modificated accordingly.
- Change: In Session::_revalidate(), makes doglegs on Segment with
incompatible caged constraints.
- Mark: vld & ieee_division works.
- Change: In TrackCost, the ripup cost is now computed from a mix between
the number of ripup *and* the data state. Restore a correct balance
of the ripping up between segments.
- New: In RoutingEvent::State::conflictSolve1(), when a very long Segment
enters in conflictSolve1(), still prefers to move it up in one piece,
but if it's not possible, it is unlikely that it will overlap with
only one or two other Segment. In that cases, blindy break it up in
the middle.
- New: In RoutingEvent::Manipulator, another overload of makeDogLeg to
allow break up at one precise point.
- Change/Bug: In RoutingEvent::Manipulator::Relax(), reset the state of
the non-overlapping Segment fragments instead of inheriting blindly
of the state of the breaked up one. Gives some supplemental slack
that allows to converge.
- Note: Now the strategy is to disable the uses of GCellRoutingSet by
setting the expand step to 0.99. This induces only a slight slow
dow and memory increase and passes all the tests...
- Mark: This revision passes all the benches except for idct, vld &
ieee_division.
- Bug: In top CMakeLists.txt the SETUP_PROJECT_PATHS was not inserting
X_USER_TOP *before* X_TOP, thus potentially allowing an obsolete
system-wide configuration to shadow an up-to-date local one.
* ./kite:
- Change: In Configuration/KiteEngine, propagate changes in Configuration
in Kite. Note that a *second* singleton is created at Kite level.
- New: KiteEngine::printConfiguration() method to allow quick checks of
the router's main parameters.
- New: ConfigurationWidget to display/sets all the revelant Katabatic/
Kite configuration parameters. To be used with the TabSettings from
the ControllerWidget.
The ConfigurationWidget is bound to the default (static) Kite
configuration, as once it has been run you obviously cannot change the
router's settings.
- Change: In TrackFixedSegment, when the source/target coordinates of the
fixed segment are outside the grid (i.e. the Cell Abutment Box) truncate
them.
- Change: In GCell::addTrackSegment, when looking for overlap between the
to be inserted TrackSegment and Blockage segment, shrink the Blockage
span by one DbU to avoid false overlap when they are just edges connexes.
- Bug: In RoutingEvent::slackenTopology, in the local segment FSM, looping
on the MaximumSlack state. Now also checks the state count.
- Change: In TrackSegment::canMoveUp() & canPivotUp() adds the "reserve"
parameter and uses it in RoutingEvent to prevent over saturated GCells.
- Change: In Configuration, parameters adjustements: expandStep increased to
0.40. Makes RoutingSets biggers but no noticeable slow down.
- Bug: In RoutingEvent::Manipulator::forceToTrack(), wrong return code,
was always return true, blocking the explorations of least good
Track.
- Bug: In RoutingEvent::_processNegociate(), must reset the "insert state"
while looping on candidate. This bug was having the same effect as
(and masking) the previous one!
- Bug: In TrackSegment::moveUp(), reset the ripup count after the move
up...
- Change: At various DebugSession opening points, sets the debug level to
200 to avoid extraneous debugging output.
- New: KiteEngine::dumpMeasures() to create a data file for later uses
by gnuplot. In interactive mode, this function is called in the
"finalize layout" stage.
- New: Adds measurments "algo", "fin" & "Segs".
- Change: In TrackSegment, _postDogLeg() & _postModify(), add segments to
"Ring" if they are directly connected to a RoutingPad. To maintain the
"border effect" after a topological slackening.
- Change: In GraphicKiteEngine, in the global routing relateds menus, suppress
the mention of "solution" as it might be unclear for an average user.
(just "Save Global Routing" or "Load Global Routing").
- Change: In RoutingEvent, conflictSolve1() tries to move up "other" blocking
segment before trying to break "self".
- Bug: In TrackSegment::reschedule(), remove from Track segments that are
now in a greater order than the current one. This bug was shown in the
TrackSegment::_postModify() method after a desalignate.
It was causing overlaps and/or routing completion false reports.
- Cleanup: In GCell, remove the DyKeyQueue support as it's been moved
to Katabatic level.
- Change: In NegociateWidow, increase the event stop thresold to 4M events
to be able to process the eFPGA matrix 16x16 (150K gates).
- Change: <PROJECT>_SEARCH_PATH are put back into the *first* tool of
a project.
- Bug: In HURRICANE_CHECK_MACRO(), the quiet flag was not correctly
implemented. User ARGV instead of argv (case sensitivity!).
- Change: New structure for the installation & CMake system.
* Tools are now grouped in "projects". There are three projects:
1. - IO: Standalones parsers/drivers (IO_USER_TOP, IO_TOP).
2. - Coriolis: Base & digital tools (CORIOLIS_USER_TOP, CORIOLIS_TOP).
3. - Chams: Analogic tools (CHAMS_USER_TOP, CHAMS_TOP).
Each *project* has a two "TOP" environement variables, for
example: IO_TOP and IO_USER_TOP. Thoses variables are the only
ones useds to locate the tool (CMake modules, headers & libraries).
The local path always takes precedence over the global one.
The localisation process occurs in each tool top CMakeLists.txt
where the macro SETUP_PROJECT_PATH is to be defined. There is no
way to put it in a shared includes file as it's the macro precisely
used to locates the includes... You have to call the macro once for
each project you wants to uses:
SETUP_PROJECT_PATHS(IO)
SETUP_PROJECT_PATHS(CORIOLIS)
* In FindTOOL.cmake, supress the <TOOL>_DIR_SEARCH and uses the
<PROJECT>_DIR_SEARCH instead (example: CORIOLIS_DIR_SEARCH).
* buildCoriolis.py modificated according to the new "TOP" scheme.
- Change: Adaptation to cmake 2.8. No more "add_subdirectory()" when
the sub directory doesn't hold a CMakeList.txt.
For "add_definition()", set policy 00005 to NEW.
- Change: Integrate IO extenal libraries.
- Change: Small compatibilities between "size_t" and "unsigned int"
under 64 bits.
- Change: Temporarily disable Equinox/Solstice in unicorn.
