* New: In Knik, in <KnikEngine>, the methods ::initGlobalRouting(), ::run()
and ::Route() now accepts one argument, a reference to a map of not to
be routed nets (the key being the name for fast search by name).
This feature is introduced to prevent the routing of nets for which
a global/detailed routing is already supplied by the designer. For now
it applies to the clock tree.
* Change: In Hurricane, in Cell::flattenNets(), do not flatten a *top net*
if at least one RoutingPad is present. In that case, we assumes that
the net has already been completly flattened.
* New: In Hurricane, in Entity, add an accessor to unique id counter.
* 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.
* New: In CRL Core, in PyCellGauge, add the missing methods.
* Bug: In Isobar, PyOccurrence_create(), the HTRY/HCATCH block was not
enclosing the constructor of Occurrence, which can throw exceptions.
When an exception was thown the Python interpreter just terminate
with the cryptic message:
"Fatal Python error: Py_EndInterpreter: thread still has a frame"
Reminder to myself: when such a message occurs, it means that the
interpreter did encounter a problem, but it's related to the isobar
interface.
* Bug: In Hurricane, UpdateSession::close(), when re-materializing, the
cells must be notified <CellChanged> *after* all the Gos are
re-materializeds. In fact they must also revalided according to the
deepness of their instanciation (the deepest first). Has still to
be done.
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 CRL Core configuration files, "display.conf", "patterns.conf" and
"technology.conf" share most of their code. So that common part is put
into "common/" and sourced from the final configuration file.
Update the documentation according the the new initialization scheme.
In CRL Core, the layout of the files under "/coriolis2/etc" changes.
Instead of having them directly under "etc", they are now replicated,
in subdirectories. Each subdirectory having the name of the associated
symbolic or real technology (they are kept separated). We have, for
now:
* etc/cmos/ : symbolic, the Alliance original one.
* etc/vsc200/ : symbolic, for G. Petley vsclib.
* etc/hcmos9/ : real, generic fake (130nm).
To tell which pair (symbolic,real) technologies must be used we create
a *second* (sigh) configuration file "coriolis2_techno.conf", and it's
hidden counterpart in the user's account, to set it up. It needs to be
separate because it is read as early as possible and select which set
of configuration files would be read.
Also add support up to METAL8 and POLY2 in CRL core and it's Alliance
parser/drivers.
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.
Cleanup:
* Cleanup: In <vlsisapd/src/bookshelf>, remove unused file Bookshelf.cpp
(may have been a parser once upon a time).
* Cleanup: In <hurricane>, in Cell::flattenNets() use flags instead of
booleans to be more readable. Allow occurrence placement checking.
* New: In <crlcore> add Python wrapper for the Ispd05 loader.
* New: In <unicorn> add option for direct loading of ISPD05 designs.
* Bug: In <hurricane/src/viewer>, RecordModel must emit
layoutAboutToBeChanged() before changing the record contents (and
layoutChanged() afterwards).
Details:
* New: In <vlsispad/utilities>, new objet Dots for displaying a kind
of progress bar.
* Change: In <vlsisapd/bookshelf>, keywords are now case-insensitive.
Added a "strict syntax" option (to be disabled for ISPD05).
* New: First working implementation of Etesian, at least for ISPD05
"bigblue1".
* Change: In <hurricane>, in Cell::flattenNets(), no longer display
a warning if an instance is unplaced, this does not make sense
when the circuit is not placed.
* New: In <crlcore>, Added translator for ISPD05 bookshelf, the
circuit is *not* placed, unlike in ISPD04 and terminal nodes
*are* true cells.
* New: In <unicorn>, added entry in import cell for ISPD05 benchmarks.
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.
Details:
* Change, in build.conf: re-added support for the newly migrated Chams
project.
* Bug, in bootstrap/../Project.py: the tool by tool compilation was
not working. Now it does (argument "--tool").
* New, in boostrap/../cmake_modules: support for retreiving the Git
hash number (SHA1). Borrowed on the net from (kudos):
Ryan Pavlik <rpavlik@iastate.edu>
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.
- Bug: In Manipulator::insertInTrack(), no longer skip overlapping segment
with an Id inferior to AutoSegment::maxId(). This counter is no longer
used, and I don't remember this test was done in the first place.
- 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.
- Change: In Cell, added doc about PlacementStatus.
- Change: In Transformation, more detailed explanations about the
orientations. A little beautifying too...
- Change: RoutingPad doc update.
- Change: Entity doc update (for id).
- Change: In HTML header/footer uses the new SoC.css.
* ./crlcore/src:
- Change: In DefDriver, added support for placement exportation.
- New: In Utility, added a "paranoid" output stream (for my extra
warnings in the router).
- Bug: In ApParser, correct parsing of connectors index (recreate
the vector).
- Change: In alliance.conf, make "blockageNet" case insensitive.
- Change: In misc.conf, added support for paranoid stream.
- Change: In x2y and CyclopMain correct verbose flags positionning.
* ./crlcore/doc:
- Change: Updated style and added some documenation.
- New: Added an id on DBo, SharedName and SharedPath to ensure
database determinism. All the hash key now uses the id instead
of the object's pointer (see _getHashValue()).
- Change: In RoutingPad, position is now only relative to the anchor,
no more (dx,dy). Add a isPlacedOccurrence() to check if all the
occurrence in the path are fixed and thus the position meaningful.
* ./hurricane/doc/hurricane:
- Change: In Cell, added doc about PlacementStatus.
- Change: In Transformation, more detailed explanations about the
orientations. A little beautifying too...
- Change: RoutingPad doc update.
- Change: Entity doc update (for id).
- Change: In HTML header/footer uses the new SoC.css.
- New: In Environment, adds a method getLIBRARYPath() to directly access the
path of an element in the SearchPath. Also added to the Python interface.
This is a quick alternative to fully export SearchPath and it's element
into the Python interface.
- Bug: In AgdsQuery::goCallBack(), take account the instance transformation.
This problem was not showing until now because there wasn't any instances...
