* Change: To allow multiple tools, and not only Knik, to link and use
FLUTE, remove it from Knik and put it at top level.
Bootsrap must compile this new tool and the library must be
included in all CMakeLists.txt depending on Knik (and soon
Anabatic).
* New: In VLSISAPD, in Configuration, add a new priority level UserFile
to distinguish between the system configuration files and the user's
configuration files (which take precedence).
* New: In Hurricane, in Script (Python), improve the API to be able
to support Chams (and remove the duplicate capability from it).
Add separate functions to perform the initialize/run(s)/finalize
cycle step by step.
* Change: In CRL Core, rename real technology <hcmos9> to <hcmos9gp>,
it's offcial name from CMP/ST. This is the 130nm.
Move the reading of the symbolic & real technologies names from
coriolisInit.py to helpers.__init__.py, to be shared with
chamsInit.py.
To avoid a clash of names inside of helpers, the two variables
of techno.py are renamed "symbolicTechnology" and "realTechnology".
Move python init system from crlcore/src/crlcore to crlcore/python.
* New: In CRL Core, In Utilities, add site-packages/pharos to the
PYTHONPATH.
* Change: In Kite, move python init system from kite/src/init to
kite/python.
* Change: In bootstrap, in ccb, builder and coriolisEnv.py, correct detection
of the windows architecture (32 or 64 bits). Under Cygwin, add the
directory of the dll into the PATH also. Uses "site-package" as the
location of Python modules (*not* "dist-package").
Use gnu++0x under Cygwin instead of c++11.
* Change: In Etesian, if Coloquinte is not found, do not stop the compilation,
just disable the tool altogether.
* Change: In Hurricane, In Backtrace, disable backtrace under Cygwin as it
uses features specific of the glibc.
* Change: In Knik, use HUGE_VAL instead of HUGE (not present under Cygwin),
add the <cmath> header.
* Change: In Unicorn, Coloquinte no longer stops the compilation.
* Change: In bootstrap, in ccb & builder, build by default with Qt4 and
provide a --qt5 command line switch to enable Qt5.
FindBootstrap.cmake now provides a qtX_wrap_cpp() macros to be
independant of the version of Qt being used.
Add all thoses options to the graphical interface to the builder.
* Change: In all the tools using Qt, switch to the qtX_*() macros from
FindBootstrap.cmake.
* Change: In Hurricane, in CellViewer, revert to the Qt4 way of connecting
signal/slots for backward compatibility.
* New: In Isobar, export the DebugSession mechanism.
* New: In Kite, In KiteEngine, add the ability to run a Python script
(hook) after the initialization of the KiteEngine.
* New: In Katabatic, in <AutoContact>, this class is no longer derived
from ExtentionGo. With the simplificated AutoContacts, there is no
reason to do so, and it will save some QuadTree insertions/deletions.
New factory function AutoContact::createFrom(Contact*) which try to
build an AutoContact on top of a Hurricane::Contact. Of course that
base contact *must fit* into one of the predefined Contact
configurations (Terminal, Turn, HTee or VTee).
NOTE: This implies that the pre-routed segments & contacts *are*
correctly articulated, which is not the case when a Cell is read
from disk in "ap" format. The pre-routing feature must be used for
now without any re-read from disk. We will implement a re-articulating
pre-process in the future.
* Change: In Katabatic, in <AutoContact> derived classes, the ::updateCache()
method now display an accurate error message if a segment is connected
but has no AutoSegment conterpart (i.e. the lookup fails).
* New: In Katabatic, in <AutoSegment>, the ::computeOptimal() method is
short-circuited for pre-routed segments, the optimal axis position is
considered to be the one it is currently on (i.e. we trust the designer).
* New: In Katabatic, in <KatabaticEngine>, the ::loadGlobalRouting()
method now accept a map of excluded nets (same as Knik). This map is
the one of pre-routed nets.
* New: In Katabatic, in layer assignment, do not try to displace fixed
segments...
* New: In Katabatic, in <AutoSegment>, new flag SegUserDefined and related
methods to know if a segment comes from the global router (Knik) or
is pre-routed (supplied by the user).
* New: In Kite, In <BuildPowerRails>, support (exclusion) for pre-routed
nets.
* New: In Kite, In <GraphicKiteEngine> new menu entry for running the
router on pre-routed nets ("Detailed Pre-Route"), also integrated
in the all-on-one route command.
* New: In Kite, In KiteEngine, new method ::_initDataBase() that group
all the initialisation steps. It is a mix of calls between Knik and
Kite initializations which are intertwinneds (may have to devellop
a shared common base at a later point). It creates the Knik grid,
then the Katabatic grid, then load pre-routed wires and power rails
and protect isolated RoutingPads.
Add support for a map of pre-routed nets (to be excluded for
Knik calls).
The method "::run()" now uses function flags, firstly to know if
it is managing pre-routed wires or general purposes ones.
* New: In Kite, in <NegociateWindow>, the "::run()" methods has now two
modes. The normal one and the 'KtPreRoutedStage' that is for routing
pre-routed nets. When in pre-route stage, the wires are fixed at the
end of this step.
* New: In Kite, in <TrackElement> add decorator for AutoSegment
isUsedDefined().
* New: In Kite, in <TrackSegment>, the various ::canDogleg() methods
returns false for a pre-routed (user-defined segment).
* New: In Kite, in PyKiteEngine, added new method runNegociatePreRouted().
Update to Qt 5:
* Change: Now requires at least cmake 2.8.9.
* Change: CMakeLists.txt needs small changes. Qt modules must be found
one by one (Core, Gui, Widgets). Must add "set(CMAKE_AUTOMOC ON)"
in the top file and replace "qt4" prefix in macros by "qt5".
Added simpler macro "setup_qt()" in FindBootstrap.cmake.
* Change: No longer need to include <QGtkStyle> is is choosen by default
according to the current desktop environment.
* Change: In <hurricane>, In HApplication, launch ExceptionWidget when
a std::exception is catched instead of silently discarting it.
New placer Tool: Etesian
* New: <etesian> analytical placer. Encapsulate Coloquinte from
Gabriel Gouvine.
* New: in <documentation>, add stub demonstration ToolEngine <smurf>.
Needs to be commented.
Miscellaneous:
* New: in <boostrap> and <unicorn>, added support for Etesian, the new
analytic placer. The tool itself will be added in the next commit.
* Bug: in <CellWidget>, when shifting the display buffer, we no longer
can copy the buffer on itself (we should never have). Now go through
a temporary one (PlaneId::AutoCopy) which is added to the
DrawingPlanes. Affect "goLeft()" and "goUp()".
* Bug: In <CellWidget>, remove the WA_PaintOnScreen flag/attribute.
When it's on, no PaintEvent is transmitted to the CellWidget
when it's the central widget of the <CellViewer> (QMainWindow).
It's something I still don't understand from the doc of Qt.
* Change: In <AreaCommand>, use the PlaneId enumeration instead of a
anonymous numerical index.
* Change: In <HApplication>, no longer catch and silently discard
standartd exceptions but launch the ExceptionWidget...
Suppress the now deprecated constructor with "Type" argument.
* Change: In <SelectionModel>, the "reset()" method is deprecated in
Qt5, instead enclose the "clear()" by a "beginResetModel()" and
"endResetModel()" pair.
* New: In <crlcore>, add support for ISPD05 benchmarks (in Bookshelf
format). Forked from ISPD04 and not finished yet.
* Change: In <Mauka>, distinguish the Action string identifier from
<Etesian>
* New: In <unicorn>, add entry for ISPD05 loader. Add entry for
<Etesian> analytic placer.
- Bug: In Cs1Candidate::consolidate(), the loop on the conflicting segment was
going one step to far. "i" must be bound to _conflicts.size()-1.
- Change: kite-text is renamed into kite.bin. It features the router only
with a subset of options consistent with cgt (python). Mainly used for
debugging purposes (gdb, valgrind, ...).
- New: Added FreeBSD/Ubuntu patches from Otacilio De Araujo
(<otaciliodearaujo@gmail.com>).
* ./kite:
- New: Makes use of cbug to display the (scary) debug messages.
- Change: Re-enable deletion of Knik in Kite destructor.
- 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.
