* Change: In bootstrap/FindBootstrap.cmake, new setup_qwt() macro to
link with the Qwt library build with Qt 5 *or* Qt 4 and not the
first found.
* Change: In Hurricane/DbU, uses <int64_t> instead of <long> to always be
sure that we use 64 bits integers for coordinates.
* Change: In Katana/KatanaEngine::_gutKatana() checks that the
RoutingPlanes have been allocateds before trying to delete them.
* 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 Anabatic:
- In _propagate(), on reaching a target, forgot to remove it from
the queue before pushing it back with the new distance. It also
simplificate the core algorithm as target as treated normal nodes.
* New: In Anabatic:
- Update cdebug to use the fastest macro version.
- More readable drawings of GCells and Edges.
- Added timer support.
- The distance is now computed in DbU::Unit (aka long) and not in
normalized float.
- The distance function is now a callback (std::function<>) that
can be changed (a default is provided at initialization).
- New concept of branch in the agglomerated connex component.
Each trace back part create a "branch" (tagged with a "branchId").
When a node is reached with the same distance, but from two
different branches, choose the the branch that was lastly created.
This create a slightly different tree which grows outward from
the newest branches.
- Makes the horizontal edges *slightly* longer than the vertical ones
to skew the tree to use vertical edges, as it is usually less
congested than the horiontal one (due to metal1 cell terminals).
It is also my understanding that it is useful to reduce the
number of vias, whithout introducing a via cost.
* New: In Bootstrap:
- Script sprof.py to perform sprof & demangle libraries execution
profile.
* ToDo: In Anabatic:
- Corner optimization. Sometimes when two corners are possible, the
wrong one is choosen. That is, one of it's edge cannot be used for
further grow of the tree.
* Change: In Hurricane Commons.h, even when cdebug print nothing, it slow
down the program (three times for Kite!). Create a macro cdebug_log
which calls cdebug *only* if the debug level is active.
* Change: In Bootstrap, in coriolisEnv.py no longer sets the environment
variable STRATUS_MAPPING_NAME (guessed by init).
* Change: In CRL Core, in System CTOR sets the default value for
"stratus1.mappingName" to "not_set" so the init can known it is not
set.
In etc/coriolis2/*/stratus1.conf, do not set "stratus1.mappingName".
In coriolisInit.py, now guess the value of "stratus1.mappingName"
if it has not already been set by the user. The complete setting
process is as follow (decreasing priority):
1. Setup by the user in his ".coriolis2/setting.py".
2. A "stratus.xml" file is detected in the current technological
directory (example: etc/coriolis2/65/cmos065/setting.xml).
3. Fallback value to "etc/coriolis2/stratus2sxlib.xml".
* Change: In bootstrap, in socInstaler.sh, use the current version of
rapidjson.
* Change: In Hurricane, in FileWriteGzStream, complie to the latest
rapidjson headers organization.
* New: In Hurricane, in Cell, emit a new signal CellDestroyed toward the
observers (i.e. the CellViewer(s)), from _preDestroy().
* Change: In Hurricane, in CellViewer, in CellObserver::notify(), manage
the CellDestroyed case. Do not forget to remove the deleted Cell
from the viewer's history.
* Change: In bootstrap, in socInstaller.py checkout the support git
repositories (currently, only rapidjson). Send the report mail
to <jpc> & <lao>.
* Bug: in VLSISAPD, in the top CMakeLists.txt, do not requires the
Hurricane cmake, it is build after (cycling dependency).
- Add OpenChams::SlicingNode class to drive/parse XML files.
OpenChams::SlicingNode contains information to create a real slicing tree (SlicingNode from hurricaneAMS)
- Minor modification in Circuit.cpp for case when HBTree are not described in XML file.
* New: In boostrap, in ccb.py, added support for the "support" project
which contains external dependencies. Currently contains only
RapidJSON. Those dependencies must be cloned here manually.
* New: In Hurricane, Initializer class for an ordered static initialization
across different compilation modules.
* Change: In Hurricane, at DataBase level, no longer save the Cells in
the libraries, but create and ordered list of Cell. Deepest cells
(leaf cells) first. To avoid dependency problems.
* New: In Hurricane, JSON support for Property.
* New; In CRL, added JSON support for AllianceFramework, Environement &
Catalog and their associated properties. Adjustment of the
AllianceLibrary creation policy.
* Bug: In Hurricane, in Instance::getClone(), the Instance::create()
was called with a wrong number of parameters, causing the the
wrong overload to be called. The position was thus not copied
generating an unplaced copy. This was causing error in the
AM2901/datapath bench, because fixed blocks where becoming
unfixed.
* Bug: In <bootstrap>, in coriolisEnv (again) an error in the
detection of the LD_LIBRARY_PATH.
* New: In <bootstrap>, socInstaller.py, a script to perform standard
SoC network installations and nighltly builds. Clone/update the
git repositories (Coriolis & Chams), build binaries and docs
in two passes, then send a mail report.
* New: In Hurricane, in Collection add simple STL iterator support.
So now the C++11 "for" instruction can be used instead of the
in-house "forEach".
Example:
forEach ( Component*, icomponent, net->getComponents() ) {
cout << (*icomponent) << endl;
}
Become:
for ( Component icomponent : net->getComponents() ) {
cout << icomponent << endl;
}
* Change: In bootstrap, in FindLEFDEF.cmake, adds my personal path where
the LEF/DEF libraries are to be found (~jpc/oa/lefdef/5.7-s038/).
* Change: In CRL Core, in LEF/DEF exporters, use the default routing
gauge and cell gauge, instead of systematically requiring "sxlib".
IMPORTANT: In order to build a *shared* library including the
*static* LEF/DEF libraries, those libraries, even if static, must
be build with the "-fPIC" flag (otherwise the compiler complains).
I have done so on my 64 bit build of LEF/DEF, but it's a completly
*local* patch. You may have to do it manually on your installations.
* Change: In CRL Core, simplify the loading sequence. The technology,
both symbolic and real is now loaded directly from coriolisInit.py
and not through the Alliance loader. This was a leftover from the
time configuration was in XML. Remove others traces of XML loading.
Remove SYMB_TECHNO_NAME, REAL_TECHNO_NAME & DISPLAY from the Alliance
environement, as they was no longer used.
Note that technology *still* need to be loader *after* Alliance
framework has been initialized.
Gauge information is moved from <alliance.conf> to <kite.conf>.
* Bug: In Coloquinte, in optimization_subproblems.cxx static variables
must not be inlined. Generate a problem when linking in debug mode
(seems the symbol gets optimised out).
* Bug: In Katabatic, in Grid::getGCell(), when the coordinate is *outside*
the area, do not try to find a GCell, directly return NULL.
* New: In Unicorn, create a generic command launcher named "coriolis" which
automatically take cares of all environement setup, then run a command
by default, it's <cgt>, but it can be anything. For example: <zsh>.
* Change: coriolis2.spec.in, Makefile.package and Builder/ccb now support
RHEL6, RHEL7 & Fedora.
* Change: In Bootstrap, added a flag to activate compilation with
openmp.
