* Bug: In HyperNet_ComponentOccurrences::Locator::progress(), (Collection
locator), the _netOccurrenceLocator (which progess along the various
Net occurrences of the HyperNet) was not in synch with the
_componentOccurrence locator of the current net. It was pointing
to the *next* net occurrence.
The result was the generation of a path for the net commponents
that was incorrect (it was the path of the *next* net occurrence),
and making Occurrence constructor throw an exception.
* Change: In Cell::flattenNets(), DeepNet::_createRoutingPads(),
Occurrence::Occurrence() and UpdateSession, added even more trace
informations.
* Change: In Hurricane::ExceptionWidget,
- Use a QTextLabel instead of a QLabel, make it "look like" a QLabel.
- Always display using text mode. Not HTML (to preserve indentation).
- Make the text of the error message selectable.
- Make it resizable.
* Change: In Hurricane::Viewer::ExceptionWidget & CRL/python/helpers/io.py,
downscale icons for non-HiDPI screen.
* Change: In CRL/etc/common/display.py, change the display threshold of
METAL1 layer so it do not appear at high scaling.
* New: In Etesian, activate the "setFixedAbHeight()" feature and export it
to Python. Allows to increase the space margin at constant height.
To be used by the P&R conductor.
* Change: In Unicorn/cgt.py, when running a script, insert the current
working directory at head of the sys.path, not at the end. So installed
modules do not shadow local one.
* New: In Anabatic::Edge, new accessor "getRawcapacity()" to know the full
capacity of the edge, that is, the real maximum number of tracks that
can go through the associated side.
* Change: In Katana/BloatProfile/Slice::tagsOverloaded(), bloating policy
change, now bloat all the instances under the GCell, not only the first
one.
* Change: In KatanaEngine::runGlobalRouter(), restore the search halo growth
policy to expanding of 3 GCells every 3 iterations.
New metrics displayed, the edge wire length length overload.
* Change: In cumulus/plugins/ConductorPlugin.py, now accepts the following
configuration parameters:
- "anabatic.globalIterationsEstimate", maximum number of global
iterations during the bloating computation passes.
- "conductor.useFixedAbHeight", tells wether the additionnal blank
space must be added so the aspect ratio is kept or the height is
kept (and the block become wider).
Disable the display of "rubber" to unclutter a little the view.
* Change: In Hurricane::Error constructors disable the backtrace generation.
(*very* slow).
* Change: In Hurricane::Library::getHierarchicalname(), more compact
naming. Remove the name of the root library.
* New: In Hurricane::Net, new type "FUSED", for component with no net.
More efficient than having one net for each.
* Change: In CellViewer, BreakpointWidget, use Angry Birds icons.
* Change: In CellWidget::State, use the hierarchical name (cached) as key
to the state. This allow to load two cells with the same name but from
different libraries in the widget history.
* Change: In PyGraphics, export "isEnabled()" and "isHighDpi()" functions.
* Change: In CRL/etc/symbolic/cmos/plugin.conf, and
CRL/etc/common/plugin.conf use the physical dimensions converters.
* Change: In CRL/etc/symbolic/cmos/technology.conf, make the GDS layer
table coherent with the default Alliance cmos.rds.
* New: CRL/python/helpers/io.py, put ErrorMessage new implementation here,
along with a new ErrorWidget written in PyQt4. It seems finally that
PyQt4 can be used alongside Coriolis Qt widgets.
New ErrorMessage.catch() static function to manage all exceptions
in except clauses.
* Change: In CRL/python/helpers/, no longer use ErrorMessage.wrapPrint(),
directly print it.
Rewrite the utilities to display Python stack traces "textStacktrace()"
and "showStacktrace()".
* Change: In CRL::AllianceFramework, shorten the names of the libraries.
* Change: In CRL::ApParser & CRL::ApDriver, more accurate translation between
Alliance connectors (C record) and Hurricane::Pin objects. Pin are no
longer made square but thin and oriented in the connecting direction.
Use the new fused net for unnamed components.
* New: In CRL::GdsParser, implementation of SREF parsing, i.e. instances.
Due to the unordered nature of the GDS stream, instances creation are
delayed until the whole stream has been parsed and only then are they
created.
For the sake of reading back Alliance s2r GDS, we assume that any
TEXT following a boundary is the Net name the boundary (component)
belongs to.
Create abutment box for Cells, computed from the bounding box, so
the Hurricane QuadTree could work properly.
Make use of the fused net for unnamed components.
* New: In Cumulus/plugins/chip, complete rewrite of the I/O pad management.
Now we can mix real (foundry) pads and a symbolic core.
To cleanly support the de-coupling between the real part and the
symbolic one we introduce a new intermediary hierarchical level, the
corona. We have now:
Chip --> Pads + Corona --> Core.
At chip level (and if we are using real pads) the layout is fully
real (excepting the corona).
The Corona contains everything that is symbolic. It has symbolic
wires extending outward the abutment box to make contact with the
real wires coming from the pads.
In the pad ring we can use corners instances (or not), pad spacers
or directly draw wires between connectors ring pads.
Provide two flavors: placement only or full place & route.
WARNING: If routing in a second step, *do not route* the *Chip* but
the *Corona*.
* Change: In Cumulus/plugins/clocktree, give the modified Cell an
additional extension of "_cts" (Clock Tree Synthesis) instead of
"_clocked", to follow the common convention.
* New: In cumulus/plugins/S2R.py, encapsulate call to Alliance S2R and
reload the translated Cell in the editor.
* New: In cumulus/plugins/core2chip, provide an utility to automatically
create a chip from a core. To work this plugins must have a basic
understanding of the pad functionalities which may differs from
foundry to foundry. So a base class CoreToChip is created, then for
each supported pad foundry a derived class is added. Currently we
support AMS c35b4 and Alliance symbolic cmos.
* Bug: In Anabatic::Configuration, read the right configuration parameter
"anabatic.topRoutinglayer" (Katana), and not the one for Katabatic...
* Change: In Unicorn/cgt.py, process the plugins in alphabetical order
to ensure a reproductible ordering of the menus...
* New: In Hurricane::UpdateSession, added "reset()" static function to
close all the currently opened sessions.
* New: In Hurricane::ExceptionWidget::catchAllwrapper(), close all
pending UpdateSession if the user choose to resume.
* Bug: In Hurricane, in StaticObservable::getObserver(), if the slot
pointer is NULL, do not try to access the owner. Returns NULL, so
the caller can be aware of the situation...
* Change: In Hurricane, in BreakpointWidget & ExceptionWidget some
cosmetic changes (fonts and window sizes).
* Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account
the constraints from the source AutoContact, as it holds the constraints
transmitted by the RoutingPads and sets up by propageConstraintsFromRp().
It is likely to be a bug affecting the original Katabatic as well.
* Change: In Anabatic, in RawGCellsUnder(), check that the segment is not
completly oustside the cell abutment box and truncate the coordinates
to the part that is inside. Use the "shrink" if we reach the east/north
border.
* Change: In Anabatic, in Configuration, no more decorator because we will
use a true derived relationship. Katana *derives* from *Anabatic* and do
not *decorate* it, so the Configuration can do the same. It also implies
that we directly create a Katana engine, not an Anabatic one.
* Change: In Anabatic, in Session, do not allow the opening of the Session
in a standalone fashion (with a static method). Instead it must be opened
using the relevant method of the Anabatic/Katana engine. This ensure we
are opening the right Session type.
* Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment
is not part of the collection by default, but will be included if the
Flags::WithSelf is set.
* Change: In Configuration, all the flags value are now defined in two steps.
Declared in the header and initialized in the module. This is to prevent
the fact that on some cases, in relation with the Python "extern C" part
modules, we need a true allocated variable. It was causing weird linking
problems.
A side effect is that they can no longer be used as entry is switches,
have to replace them by if/else.
* New: In Anabatic, new GCell::getNeighborAt() utility function.
* Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with
the grid type... Back annote all the edges capacity (north & east) with
the reserved local capacity.
* New: Complete portage of Kite over Anabatic. The new engine is christened
"Katana" for Kite-Analogic. When it's capabilities and performances
will be on a part with Kite, it is to completly replace it (and take
back the "Kite" name). Preliminary tests seems to show that, contrary
to intuition (because built on a more complex/slower grid), it is even
slightly faster than Kite 8-).
* New: In Bootstrap, add cmake detection for libbfd.
* New: In Hurricane, in Backtrace, add BFD support to read debuginfo from
the shared libraries (aka DSO) when compiled with "-g". This avoid the
tedious step of running gdb after generating a core dump. It is also
mandatory in ExceptioWidget to known from where an exception was thrown
as Qt::notify() block all C++ exceptions.
Currently works only under Linux (gcc or clang), may be extended in
the future.
The BFD reading is based on the small utility from:
Don Hatch (hatch@plunk.org)
http://www.plunk.org/~hatch/goodies/backtracefilt.C
And small trinket: adjust the size of the window for high DPI screens.
* New: In CRL Core & Unicorn add link toward libbfd, if needed.
* Bug: In Hurricane, in HApplication, ExceptionWidget ans PyHurricane.h,
forgot to catch the Hurricane::Bug exception which was leading to
terminate() without explanations.
* Change: In Katabatic, In GCellTopology, now support one GCell with
five metal1 terminal of the same net. This unlikely configuration
did appear in the SNX for the first time...
* New: In Hurricane, in Graphics, add a new static method ::isHighDpi()
which returns true if the DPI is greater than 192. A "normal" screen
is typically 96dpi, we sets the trigger at twice that value.
Then in all the widgets with size settings, we uses that method to
select the more appropriate size.
* Bug: In Hurricane, in PyHurricane.h the macro HCATCH was not catching
standard STL exceptions. This was the source of the cryptic message:
"Fatal Python error: Py_EndInterpreter: thread still has a frame"
The Python interpreter was interrupted uncleanly bypassing it's own
exceptions mechanism.
In PyViewer, the Viewer *do not* inherit from a base class (in the
Python export).
* New: In Hurricane, in DbU, compute maximum values (in double) for
grid, lambda & physical (in meter) so now the DbU::toGrid(),
DbU::toLambda() & DbU::toPhysical() methods can check for out of
bound values, and throw an exception.
* Change: In Hurricane, ExceptionWidget::catchAllWrapper() now returns
a boolean, set to <true> if an exception has been catched. Allow
callers to interrupt themselves if a problem has occured.
* Bug: In Kite & Etesian, in the Python wrapper, send a Python exception
if catchAllwrapper() did return true, instead of continuing...
* Change: In Kite & Etesian, adds a setViewer() method (exported in Python)
to use the graphical ExceptionWidget when in graphic mode.
* Bug: In Cumulus, in PadsCorona.py the check for the core vs. chip size
was not returning False when invalid.
* New: In CRL Core, in Vst driver, add a support IEEE VHDL. Inactive for
now as I don't see clearly the policy for selecting it or not.
Remove the code of the old Vst driver.
In Blif parser, check for non-existent models (incomplete or
corrupted Blif file). Found by G. Gouvine.
* New: Added extras file for IDE-like support under Emacs.
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.
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.
- New: In ExceptionWidget, mimic more closely the behavior of a QDialog.
Uses QTextEdit/QTextDocument for the trace. Static "all in one" methods,
build from various exceptions/Errors & QString. Automatic window centering
when the trace is displayed.
- In CellViewer, adds a shortcut for launching Stratus scipts: SHIFT+P,S
and one for pure Python scripts: SHIFT+P,P.
- In ExceptionWidget, put the trace inside a QScrollArea so all the call
stack can be viewed regardless of the window's size. It seems that
QFontMetrics has problems to compute the right text size when using
a Qt::RichText enabled widget. Adds some "manual" corrections, hope
they will be sufficiently portables.
- New: Backtrace to print the stack when an exception is thrown.
- New: In Error, support for Backtrack.
- Change: In TextTranslator, provides a default HTML translator instead of
building it every time it was needed.
- Bug: In Common, when demangling a C++ symbol fails, returns the empty
string instead of NULL.
* ./hurricane/src/viewer:
- New: In Exception, support for the Backtrack new feature.
* ./hurricane/src/isobar:
- Change: In PyHurricane, when catching a C++ exception, adds a newline to
have a more clean display.
- Cleanup: In Slot.h, comment out print for debug.
- New: In CellViewer, adds a renameCell() method to "rename" the currently
loaded Cell "in place". Utility function for SaveCellDialog (see below).
