* Change: In Hurricane, in Plug::setNet(), more informative error messages.
* Change: In Hurricane, In Segment, more informative error messages.
* Change: In Hurricane, In DeepNet, accessor for the Net occurrence.
* Bug: In Katabatic, in AutoSegment::create(), error message uses correct
variables (vertical was using horizontal)...
* Change: In Kite, in BuildPowerRails, already existing wiring in instances
is copied up as blockage. Uses blockage layer instead of true layer
(it was a bug).
* Change: In Kite, in BuildPreRouted, consider as manual global routing
nets with only default wiring (default size wire & contacts).
Non-default routing is flagged as fixed (with the NetRoutingState
property).
* 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 all to CMakeLists.txt, disable the warning about deprecated
WIN32 under cygwin.
* New: In boostrap, in ccb.py, coriolisEnv.py and builder/Configuration.py
add recognition in uname for the values returned under Windows/Cygwin.
* New: In Documenation, in UsersGuide.rst add some informations about
Cygwin and a section for the devel branch.
* Bug: In Kite, in TrackCost, the boolean attribute "_forGlobal" was not
initialized in the constructor causing the non-deterministic behavior.
Arrrrgggghhhhhh.
* Bug: In Kite, in PyKiteEngine, forgot to perform the
"balanceGlobalDensity()" in the layer assign Python wrapper, another
cause for non-determinism.
* Change: In Kite, In KiteEngine, print the configuration at the same
point as in the python script (to get identical output).
* New: In Katabatic, add the ability to decorate some (i.e. few) nets
with a state that indicate to Katabatic & Kite what to do with it.
The possible states are:
1. Fixed : all the wire are in fixed positions. The router cannot
move them and account them as obstacles.
2. ManualGlobalRoute : a user-defined topology is supplied. The
wires still have to be detailed route in "Detailed Pre-Route"
but will be skipped for the global routing and fixed for the
general Detailed route.
3. AutomaticGlobalRoute : ordinary nets, to be global routed then
detail routed.
4. Excluded : do not try to global or detail route thoses nets.
5. MixedPreRoute : mask combining Fixed and ManualGlobalRoute.
Not all nets have this property, only those that needs a special
processing.
To ease the access to the state, it is nested inside a
PrivateProperty in the net (NetRoutingProperty), with an extension
access class (NetRoutingExtension).
* New: In Kite, take account of NetRoutingState. Pointers to the
net's states are strored inside an internal map for faster access.
The property is *not* deleted when Kite is destroyed. The property
will remains until the Net itself is destroyed.
As a consequence, the lists that where passed to high level
function are removed as the information can now be accessed directly
through the net NetRoutingProperty.
* New: In Unicorn, in CgtMain, comply with the update interface.
* New: In documentation, update the User's Guide to explain the Pre-routed
step of Kite.
* 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().
* Change: In Kite, Katabatic & Knik, express the number of tracks truly
available to the global router by the number of tracks reserved to
the local routage inside a GCell. Replace the ratio parameter
"hEdgeCapacity" by an integer parameter "hTracksReservedLocal"
(duplicate for verticals).
It is more explicit to give directly the number of tracks that
are to be used locally, and potentially saves us from rouding
problems when calculating the number of availables tracks.
Note: we cannot do that for the layer saturateRatio as it
uses the density ratio that take account local wires, leading
to fractional results.
* Change: In Katabatic, in <GCellGrid>, rename checkEdgeSaturation()
into checkEdgeOverflow(), more explicit.
* Change: In Knik, in <Graph>, display the computed capacities of the
lower left node edges (should be the same througout all the grid).
* Change: In Unicorn, in <cgt.py>, uses the new parameters names for
edge density.
Placement management:
* Change: In <metis>, always disable the hMetis support regardless of
it being detected or not as the placer is still unable manage the
final bin contents.
Routing gauge management:
* Bug: In CRL Core, <vsclib/alliance.conf>, set the correct pitches and
size for the routing layers and the cell gauge.
* Change: In Katabatic & Kite, extract the correct extension cap for each
routing layer from the layers characteristics (cache then in
Katabatic::Configuration).
* Change: In Katabatic, <AutoSegment>, create segment with the wire width
defined in the gauge. For AutoSegment created on already existing
Segment from the global routing, adjust the width.
* Change: In Katabatic, <AutoSegment>, more accurate information about how
a segment is connected to terminal via source and/or target.
The flag SegStrongTerminal is splitted into SegSourceTerminal and
SegSourceTarget (but still used as a mask). So now we can know by
which end an AutoSegment is connected to a terminal.
* Change: In Katabatic, ::doRp_Access(), create constraint freeing segments
not only when HSmall but also when VSmall (more critical for <vsclib>).
Otherwise we may see AutoSegments with incompatible source/target
constraints.
* Change: In Kite, BuildPowerRails, do not create blockage on PinOnly
layers *but* still create power rails planes. This is a temporary
workaround for <vsclib> where the METAL1 blockages overlaps the
terminals (it was fine for Nero, but they shouldn't for Kite).
* Change: In Kite, <RoutingEvent>, if a TrackSegment is overconstrained,
directly bybass it's slackening state to DataNegociate::Slacken.
Also rename the flag "_canHandleConstraints" to "_overConstrained",
seems clearer to me.
Miscellaneous:
* Change: In CRL Core, <Utilities>, add a "pass-though" capability on the
mstream to temporarily make them print everything.
In Katabatic & Kite, remove all hard-coded values related to track pitches.
* New: In <Session>, add more convenience function to access RoutingGauge
characteristics.
* New: In <AutoSegment>, <AutoContact>, add support for the "depth spin",
that is, if the source/target contacts are going "top" or "down".
Used to compute the perpandicular pitch. Need a small modification
of the revalidation mechanism. The observers of <AutoSegment> are
notified when the spin changes.
* New: In <AutoSegment>, the getPPitch() method allow to compute the
"perpandicular pitch". For now it is simply the greatest from the
source perpandicular pitch and the target perpandicular pitch.
Make uses of the "depth spin".
* New: In <TrackElement>, <TrackSegment>, cache the perpandicular pitch.
Updated through the notification from the observable.
When upgrading from doxygen 1.5.x to 1.8.5 the way the documentation
is generated has underwent many changes, particularly in the headers.
* Change: In <header.html>, must include the javascripts <jquery.js>
and <dynsections.js>.
* In <CMakeLists.txt>, as the header is customized, doxygen seems not
copy some files like the javascripts and some images (open.png,
closed.png). So we copy them from doxygen installation and make
the CMakeLists.txt install them. I hope they will not change too
much in the future.
* In <doxyfile>, disable markdown support as it do not interpret
correctly the formating we already adopted (with a left margin
to put command into). Use HTML_EXTRA_STYLESHEET instead of
HTML_STYLESHEET. Enable the index (DISABLE_INDEX=NO), for the
top header. Enable dot for inheritance diagram. Set the
EXAMPLE_PATH=. to include the synthetic hierarchy.
Correct the tag inclusion (faulty path in some places).
* In <SoC.css>, create style for the new header generated by doxygen.
* In the documentation, move the synthetic hierarchy into a module.
Miscellaneous:
* Change: In <crlcore>, in display.conf use the same display threshold
for both METAL2 & METAL3.
In alliance.conf, the side of VIAs in the gauge is 2l (not 3l).
In kite.conf, separate edge densities for H/V.
* Change: In <Cell>, in flattenNets() use flag as argument, not a
boolean. Do not create rings for clock or supply nets.
* Change: In <DeepNet>, in _createRoutingPads() do not create rings
for clock or supply net (duplicated policy as in Cell::flattenNets()).
* Bug: In <ControllerWidget>, at last find the bad signal disconnect
that was causing ungraceful messages.
* Change: In <knik>, in Edge display occupancy/capacity in the string
name. Improved display progress and debugging capabilities.
Improved exception catch & breakpoint managment:
* Bug: In <PaletteWidget>, in updateExtensions() replace the calls to
deleteLayer() by delete. This cause the widget to be immediatly
erased instead of waiting for the event queue to be completly
processed. This was causing the widget to be left in a incoherent
state when stoping at a breakpoint.
* Bug: In <BreakpointWidget>, in execNoModal(), flush the main event
loop (QApplication::flush()) *before* lauching the *local* event
loop. This is to ensure all widgets are in their final state when
waiting (especially <PaletteWidget>).
* Change: In <ExceptionWidget>, new method catchAllWrapper() to
execute any std::function< void() > function/method with a "try"/
"catch" wraparound and lauch the widget in case something is catch.
* New: In <hurricane>, support for a oberver pattern, backported from
<katabatic> with an Obervable capable of being linked to any
number of Obervers.
* New: In <Cell>, made it observable to detect Cell change, currently
emit two kind of signals:
- Cell::CellAboutToChange : *before* any change.
- Cell::CellChanged : *after* the change has been completed.
* New: In <UpdateSession>, in Go::invalidate() add the Cell owning the
Go to the UPDATOR_STACK (of course the cell is added only once).
In addition, when the Cell is added, send a notification of
Cell::CellAboutToChange to all it's observers. The slave instances
are also invalidated.
Conversely in UpdateSession::_preDestroy() for each invalidated
Cell send a Cell::CellChanged notification to all observer.
The UPDATOR_STACK has been slightly amended to accept Cell which
are not Gos. Prior to this, the Cell where completly excluded from
the UpdateSession mechanism, so it's instances where never actualised
of anything referring to the Cell for that matter.
Note: we use two different mechanisms to transmit a Cell change,
observers and the slave instance map. I think at some point it
should be unificated.
* Change: In <CellViewer>, make it a Cell observer to redraw when the
cell is modificated (also update the palette).
Uses the catchAllWrapper() to protect all critical actions.
* Change: In <GraphicTool>, no longer need of cellPreModificated and
cellPostModificated signals. Now done through the Cell obersvers.
* Change: In <mauka>, <etesian> & <kite> now uses the catchAllWrapper
method for protection (need to split methods in two, to be able
to pass it as argument). No longer emit cellPreModificated and
cellPostModificated.
Support for RoutingGauge in P&R:
* Bug: In <placeandroute.py>, the connection from the internal power
ring to the connectors was not done correctly. Wrong contact layers
leading to a gap.
* Change: In <BuildPowerRails>, detection of the corona signals based
on how the "pck_px" pad is connected. No longer based on name
matching.
* Change: In <placeandroute.py>, support for 2 routing metal only
(3 metal in the technology).
* Change: In <katabatic> & <kite> support for a "top layer" limitation
on the routing gauge, this allows to use only two routing metals
(METAL2 & METAL3). Work in progress.
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.
Details:
* New: in <bootstrap>: add support for devtoolset-2 in ccb. Run the
cmake commands through 'scl', set shell environment variables
BOOST_INCLUDEDIR & BOOST_LIBRARYDIR and disable the default
system path search.
* Change: In various flex scanners add the %nounput to suppress
compiler warnings.
* Change: Little cleanup for g++ 4.8.1 as it's more strict.
* Change: In various top CMakeLists.txt, suppress extraneous '/'
after DESTDIR.
Documentation restructuration:
* Bug: in <hurricane>: bad figure for transf-R1.
* Change, in <kite>: Remove deprecated configuration variables.
* New: documentation <tool> to regroup all documentation not directly
related to one tool.
* Change, in <crlcore>, move the user's guide and the top doc index
into <documentation>.
* New, in <documenation>: added Python script demo based on AM2901.
Project hierarchy reorganisation:
* With svn, we were doing a tool by tool checkout, suppressing the
whole repository hierarchy level.
* The tools were also grouped, inside one repository, into multiple
projects (<bootstrap>, <vlsisapd>, <coriolis>).
* We do not want to split up each tool into a separate repository,
given their tight integration (except for vlsisapd).
* We choose to simplify, and consider all tools in a svn repository
one project. Due to the way Git clone repositories, the directory
containing the project is now to be seen under "src/".
CMake modifications:
* Now that the <vlsisapd> and <bootstrap> projects are merged into
coriolis, modificate the top CMakeLists.txt of each tool to uses
only Coriolis (and bootstrap hard wired).
CCB compile script modifications:
* Uses the new source tree hierarchy, with the project directory
inserted.
* Remove (comment) all parts relateds to svn managment.
* Git is sufficiently simple so that we do not want to integrate
command shortcut into the script.
SVN cleanup:
* Remove the obsolete <chamsin> tool, that has become the full fledged
<chams> project long time ago.
- In Session::_canonize(): if the canonical segment has never had it's axis
sets, put it into *optimal* position instead of simply constraint
compliant. Force realignment of the segment sets as rounding errors
may introduce slight misalignment on the axis (causing error laters
in the various contact topological updates).
This also seems to solve the ludicrous problem of negative ratio of
expansion wires... (segments *not* at their optimal position at the
start).
- In LayerAssign, KatabaticEngine::layerAssign(), suppress the triple loop
enclosign the desaturation. Now desaturate each layer exactly once and
from bottom to top.
- New: Added FreeBSD/Ubuntu patches from Otacilio De Araujo
(<otaciliodearaujo@gmail.com>).
* ./katabatic:
- New: Makes use of cbug to display the (scary) debug messages.
- 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.
- New: In GCell, compute a "fragmentation" indice, the average free track
length, the more fragmented, the smaller the indice.
- New: In AutoSegment::canMoveUp(), when requested, not only check for free
(parallel) track in the up layer but also check that the begin/end
local segments created to maintain layer connexity do not creates too
much fragmentation. This fragment could prove critical in higly dense
GCells.
- Change: In LayerAssign, disable the ::rpDesaturate() steps, after optimization
the router can handle 10 terminals per GCells in M2 without problem.
And ::rpDesaturate() must uses GCell::stepNetDesaturate() and *not*
directly ::stepDesaturate().
- 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).
- Change: In GCell & GCellGrid, unificated way of computing all the GCell's
densities.
- Change: In GCell::stepDesaturate(), uses shearUp() instead of moveUp().
- Change: In AutoSegment, new method ::shearUp() to avoid moveUp() saturating
GCells as side-effect.
- 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.
- 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.
- Change: In LayerAssign, desaturate until the last two top layers are reacheds
instead of only METAL2 & METAL3.
- Change: In Configuration/GCellGrid/GCell, correct computation of the edges
capacity (based on the numbers of avalaibles layers and not hard-wired to
4).
- New: To pass the ibmXX, new parameter "katabatic.saturateRp" which allows
to sets the threshold above which a GCell has too much RoutingPads in
it and must be further desaturated. Must be 8 for FPGA, and 10 for ibm.
- Bug: In LoadGrByNet(), when looking for the starting GCell, the computation
of unconnecteds RoutingPads was incorrect, too great and letting the
router believe that the routage was incomplete.
- 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.
- 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 KatabaticEngine, the containers used to store the "nets to
route" is changed from a vector<> to a set<> sorted by the Nets names.
Uses more memory but allows much faster Net deletion.
- New: In _loadNetGlobalRouting(Net*), detect non-routed Nets. A Net is
considered as unrouted if it's 10 first RoutingPads have no slave
Segment. The Net is withdrawn from the set of Nets to route.
- Bug: In GCellConfiguration::_GCell_1G_1L1(), correctly compute the
access flag passed to _GCell_rp_Access().
- Change: In AutoContact::restrictConstraintBox() adds "warnOnError"
parameter to shut down warnings.
- New: KatabaticEngine::_computeNetConstraints() now also returns a set<>
of segments on which constraints are incompatibles. All the NetConstraints
related functions are modificateds accordingly.
- Change: In KatabaticEngine::_loadNetGlobalRouting(), create dogleg
on overconstrained Segments computed by a call to _computeNetConstraints().
Overconstraineds Segments can occurs when a global is directly
connecting two punctual RoutingPads (see "ieee_division").
As a side effect, and to avoid looping each Net is revalidated
*before* making any dogleg. So Nets are revalidated one by one instead
of alltogether.
- Change: In AutoSegment::_toConstraintAxis(), do nothing if constraint
interval is empty.
- Bug: In KatabaticEnginge::_desaturate() (part of LayerAssign), reset
the moved up Segment pointer between iterations. Suppress the warning
about the GCell's DyKeyQueue beeing not revalidated on deletion.
- Change: In LoadGrByNet, manage the 4G+3L1 configuration with the generic
_GCell_xG_xL1_xL3(). Needed for "dct_lvl2".
- 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.
* ./katabatic:
- Change: In Configuration/KatabaticEngine, introduce a static Configuration
object (singleton) to handle the default configuration. Configuration are
now created only through cloning operations. In KatabaticEngine, the
_configuration becomes a pointer (previoulsy an value).
Confifuration becames a singleton and a decorator.
Also adds a print method to nicely display configurations values on
the terminal.
- Change: In Grid/BaseGrid, add an Abutment Box attribute (to facilitate
segment truncation in Kite::TrackFixedSegment.
- Change: In Grid/BaseGrid::Axis, when computing a row/column index using
the graduation table, if the coordinate is exactly on the last
graduation, return the last GCell instead of "out of bound".
- Change: In GCell::hasFreeTrack(), AutoSegment::canMoveUp() &
AutoSegment::canPivotUp() adds a "reserve" parameter to modify the
amount of wirelength to remains free after the insertion.
- Bug: In GCell, bad cast between <size_t> and <unsigned int>, showed only
under 64 bits.
- New: In KatabaticEngine::printMeasures(), adds a support for measurments,
both time and memory size in Mb are stored for each tag.
- New: Adds measurements "Gates", "GCells", "load" & "assign".
- New: In GCell & LayerAssign, adds a supplemental desaturation steps when
a GCell containts too many (more than 7) RoutingPads in M1. This is
especially useful for the eFPGA matrix with it's custom made cells.
- Change: Uses a map instead of a sorted vector in the layer assignment
steps. It was used to order GCells by density, and causing terrific
slowdown on big examples. Namely the eFPGA 16x16 took 1h20, now it's
down to 21 seconds...
Devellop a new object <DyKeyQueue> to handle map with elements
whose key *can* change. Next step is to normalize the key caching
mechanism and to templatize.
- Change: In LayerAssign, account the number of globals AutoSegments
moved up.
- 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.

- SVN MOVE: Source tree simplification & uniformisation. Now all tools
are at the same level, directly under the root of the repository.
No more "coriolis/src".
