- New: In BuildPowerRails, special processing for the power ring segments.
The "diagonal" of vias at each corner is causing a misbehavior of the
routing algorithm (due to fully saturated GCells in one direction).
As a temporary fix, extend the segments so they form a "square corner".
(problem arise on "d_in_i(22)").
- New: In RoutingEvent::_processNegociate, disable the "isForcedToHint()"
feature. No noticeable loss of quality or speed.
- New: In TrackElement/TrackSegment, wraps the AutoSegment parent's mechanism.
Allows to gets the DataNegociate of either the segment or it's parent.
- New: State::solveFullBlockages(), dedicated method to solves the case when
all the allowed tracks of a segment are blocked, tries to moves up
local segments and to break-up global ones.
- New: RoutingEventLoop, a more sophisticated way to detect looping.
Maintain a dynamic histogram of the last N (default 10) segments routeds,
with the count of how many times they have occurred. If that count
exeed 40, we *may* be facing a loop.
- Change: In State::conflictSolve1, implement new policy. The global segments
no more can be broken by local ones. The idea behind is that breaking
a global on the request of a local will only produce more cluttering
in the GCell. Globals must be keep straigth pass through, especially
inside near-saturated GCells. Globals breaking however can occurs at
another global's request.
- Change: In TrackCost, implement the new policy about locals segments that
cannot break globals segments. The sorting class now accept flags to
modulate the sorting function. Two options avalaibles: IgnoreAxisWeigth
(to uses for strap segments) and DiscardGlobals (to uses with locals).
- Change: In TrackCost, the "distance to fixed" have now an upper bound of
50 lambdas (no need to be greater because it means it's outside the
begin & en GCells). Take account not only of fixed segment, but also
of placed segments which makes bound.
- Bug: In Track::_check(), while calling each individual TrackSegment check,
uses it as the *first* argument of the "or", otherwise it may not be
called.
- Bug: In ProtectRoutingPad, loop over segment Collections while modificating
it was producing non-deterministic results. The fact that a collection
must be not modificated while beeing iterated is becoming a more and more
painful problem.
- Change: Big cleanup. Supress all the GCell level: GCell, GCellGrid,
GCellRoutingSet. Blockages now managed inside the BuildPower.
- New: In NegociateWindow, Histogram of GCell densities in Gnuplot
format.
- New: In BuilPowerRails & BuildBlockage, specific support for chip-level
design. The Alliance "top chip" design hierarchical structure is
hard-coded. Top level POWER/GROUND/CLOCK nets must always have the
<vsse>, <vdde>, <ck>, <vssi>, <vddi>, <ckc>, <cki> names.
Specific method to get trans-hierarchical root nets, espcially in
case of global ones (POWER/GROUND). Clock is *not* global.
Some correction in the manner obscured tracks are computeds.
- New: ProtectRoutingPad module that perform a more clean work for protecting
unused RoutingPad.
- Bug: In BuildPowerRails, uses stable_sort<> instead of sort<>, which
causes unexplained core dumps (seems to try to perform a comparison
using the "end" pseudo element). Already occured in Knik, no explanation
other than a STL bug.
- Change: Slight changes in the weights to move up. Now needs a full empty
track instead of a half one.
- 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: 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.
- 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: 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.
