* Bug: In all CMakeLists.txt, it seems I was doing a worng use of
target_link_library(). No longer add dependencies to the C++ base
library but instead either to the Python associated module or
to the final binaries. This was inderectly causing the linking
problem related to Python (which was a misdirection).
* Bug: Typo in FindLibexecinfo.cmake, do not use FindLib[E]xecinfo.
* Change: In CRL/ccore/CMakeLists.txt, activate SKIP_AUTOMOC on
bison/flex generated files.
* Bug: In viewer/PyHApplication, do not delete the C++ object in
the Python destroy method.
* New: Python/C++ API level:
* Write a new C++/template wrapper to get rid of boost::python
* The int & long Python type are now merged. So a C/C++ level,
it became "PyLong_X" (remove "PyInt_X") and at Python code
level, it became "int" (remove "long").
* Change: VLSISAPD finally defunct.
* Configuration is now integrated as a Hurricane component,
makes use of the new C++/template wrapper.
* vlsisapd is now defunct. Keep it in the source for now as
some remaining non essential code may have to be ported in
the future.
* Note: Python code (copy of the migration howto):
* New print function syntax print().
* Changed "dict.has_key(k)" for "k" in dict.
* Changed "except Exception, e" for "except Exception as e".
* The division "/" is now the floating point division, even if
both operand are integers. So 3/2 now gives 1.5 and no longer 1.
The integer division is now "//" : 1 = 3//2. So have to carefully
review the code to update. Most of the time we want to use "//".
We must never change to float for long that, in fact, represents
DbU (exposed as Python int type).
* execfile() must be replaced by exec(open("file").read()).
* iter().__next__() becomes iter(x).__next__().
* __getslice__() has been removed, integrated to __getitem__().
* The formating used for str(type(o)) has changed, so In Stratus,
have to update them ("<class 'MyClass'>" instead of "MyClass").
* the "types" module no longer supply values for default types
like str (types.StringType) or list (types.StringType).
Must use "isinstance()" where they were occuring.
* Remove the 'L' to indicate "long integer" (like "12L"), now
all Python integer are long.
* Change in bootstrap:
* Ported Coriolis builder (ccb) to Python3.
* Ported Coriolis socInstaller.py to Python3.
* Note: In PyQt4+Python3, QVariant no longer exists. Use None or
directly convert using the python syntax: bool(x), int(x), ...
By default, it is a string (str).
* Note: PyQt4 bindings & Python3 under SL7.
* In order to compile user's must upgrade to my own rebuild of
PyQt 4 & 5 bindings 4.19.21-1.el7.soc.
* Bug: In cumulus/plugins.block.htree.HTree.splitNet(), set the root
buffer of the H-Tree to the original signal (mainly: top clock).
Strangely, it was only done when working in full chip mode.
Note: Keep the various hfnsX.py as toolboxes for future experiments.
* New: cumulus/plugins/block/hfns3.py, build the trunk of the
net as a RMST. First with the "Iterative One Steiner Point"
(terribly slow above 100 points) then with FLUTE.
For the global routing trunk, must be very cautious to
check that the cluster "graph point" is the one of the
it's buffer RoutingPad so both end up in the same GCell.
* New: cumulus/plugins/block/timing.py, stub for basic
timing computation and conversion between sink and
capacitance. Currently based on the fake 350nm given as
example in SxLib ("man sxlib"...).
* Change: In CRL/helpers, cumulus/plugins, oroshi & karakaze,
Move towards more Python PEP8 compliance:
* All indentations sets to 4 spaces (in progress).
* In plugins, remove messages about software collections
and RHEL (too many case could wrongly lead to that).
Instead systematically uses "helpers.io.catch()".
* Put in lowercases all modules names. Note that C++ exported
modules *keep* their Capitalized names (to preserve the
identity with the C++ namespace).
* When making import, use full path.
* Rename the run function from "ScriptMain()" to "scriptMain()".
* Cleanup: In CRL/etc, remove obsoleted configuration files,
the one ending in ".conf". Keep those who have not been ported
to the new style yet.
* New: In Hurricane/src/configuration, first trial at replacing the
C preprocessor macros by C++ templates. Applied first to configuration
from VLSISAPD.
This is unfinished business, just a limited demonstrator for now.
It is installed as a separate Python library "Cfg2" which do not
interact with the rest of Coriiolis.
The end goal is to fully remove boost and merge VLSISAPD useful
components directly inside Hurricane.
* Change: In all tools, FindTOOL.cmake, no longer use LIB_SUFFIX to
search for tool libraries but try "lib64/" then "lib/".
* Change: In bootstrap/socInstaller.py, take Debian 10 into account.
* Change: In bootstrap/docker, move from Debian 9 to Debian 10.
* Change: In documentation, now generate the overall documentation using
Pelican instead of Sphinx. This allows to have an unified approach
between the coriolis.lip6.fr website and the local documentation.
So we keep using "only" two doc generators: doxygen & Pelican.
* Change: In bootstrap/FindBoostrap.cmake, remove the -fsanitize=address
as it requires the "san" librarie which may be difficult to install.
* Change: In CRL/symbolic/cmos45/kite.py, decrease the METAL3 pitch from
10l to 8l. This is for testing with 4 routing metal only technology
like AMS c35b4 symbolic.
* Change: In Katana/BloatProfile, add static bloat option, that is, only
cell bloated in the first pass will be bloated again in subsequent
ones.
Add a "katana.bloatOverloadAdd" parameter to more easily control the
amount added to the computed overload.
* Change: In Oroshi, start integration of multi capacitors as generator.
Translate generator parameter into CapacitorStack ones. Add code for
routing unit capacitor.
This commit contains two set of features that should have been commited
separately.
1. Compliance with clang 5.0.1, tested with the RedHat collection
llvm-toolset-7. This allow Coriolis to be compiled under Darwin (MacOS)
with Xcode & macports. The bootstrap install system has been modificated
accordingly.
2. The basic support for routing density driven placement. Related
features are:
* Bloat property. Each Occurrence of an Instance can be individually
bloated. This property not attached to any tool to allow the placer and
router to share it as wanted. Nevertheless, it is defined in Etesian.
* BloatProfile in Katana, add individual Bloat properties to Instances
occurrences based on the East & North overflowed edges of each GCell.
* Support in ToolEngine for a "pass number" of a tool. This pass number
is mainly used to make "per pass" measurements. The MeasureSet system
is improved accordingly to support multiple values of a same measure.
* Embryo of "P&R Conductor" to perform the place & route loop until the
design is successfully placed. May be the first brick of a Silicon
Compiler.
* Change: In boostrap/FindBoostrap.cmake, in setup_boost(), added tag to
the python component for macport (ex: python27).
* Change: In boostrap/build.conf, put etesian before anabatic for
instance occurrence BloatProperty dependency.
Added option support for the "llvm-toolset-7" collection to build
against clang 5.0.1.
* Bug: In Hurricane::getRecord( const pair<T,U>& ), the getSlot<> templates
for first & second arguments must be called with <const T> and <const U>
as the pair itself is const (and not simply <T> & <U>).
* Change: In Hurricane::getSlot() temlate, only use "string" arguments and
not const string&, simpler for template argument deduction.
* Bug: In Hurricane::AnalogCellExtension, the StandardPrivateProperty<>
template has a static member "_name". Clang did show that the template
for this static number has to be put inside the namespace where the
template *is defined* (i.e. Hurricane) instead of the namespace where
it is instanciated (i.e. Analog).
* Bug: In Isobar, Matrix_FromListOfList(), PyInt_AsPlacementStatus() must
be put outside the C linkage back in the Isobar C++ namespace (clang).
* Bug: In Hurricane::DBo::~DBo, and derived add a throw() specification
(clang).
* Bug: In Hurricane::RegularLayer::getEnclosure() & setEnclosure(), change
signature so it matches the one of the base class (clang).
* Bug: In Hurricane::CellPrinter, use double brackets for initializer list
(clang).
* Change: In Hurricane::Breakpoint, reverse the meaning of the error level.
Only error level *lesser or equal* than the stop level will be enabled.
* Bug: In CRL/python/helpers/__init__.loadUserSettings(), must put the
current working directory in the sys.path as in certain configuration
it may not be included.
* Bug: In CRL::ApDriver, DumpSegments(), no longer generate segments when
encountering a RoutingPad on a top-level Pin Occurrence. The segment
was generated in the wrong direction, creating DRC violations on the
"mips_core_flat" example.
* Change: In CRL::Measures, partial re-design of the measurements management.
Now, each kind of measure can accept multiple values put in a vector.
The index is intented to match a tool run number.
* Change: In CRL::Histogram, add support for multiple sets of datas,
indexeds with tool run number.
* Change: In CRL::ToolEngine, add support for multiple pass number, add
addMeasure<> templates for the various data-types.
* Change: In CRL::gdsDriver & CRL::gdsParser(), comment out unused GDS record
name constants.
* New: Etesian::BloatProperty, property to attach to Instance occurrences
that contains the extra number of pitch to add to the cell width.
* Bug: In AutoSegment::CompareByDepthLength, the segment length comparison
was wrong, it was always returning true, which broke the "strick weak
ordering" of the comparison.
This was producing a core-dump in GCell::updateDensity() when sorting
a vector<>. The end() iterator was being dereferenced, leading to the
problem.
* Bug: In Katana::DataSymmetric::checkPairing(), the test for segments
whose axis is perpandicular to the symmetry axis was wrong
("!=" instead of "-").
* New: In Katana/GlobalRoute, new ::selectSegments(), selectOverloadedgcells()
and selectBloatedInstances() to automatically select segments from
overloaded edges, overloaded GCells and bloated cells.
* Change: In KatanaEngine, return a more detailed success state, distinguish
between global and detailed.
Add support for multiple routing iterations.
* New: In cumulus/python/plugins/ConductorPlugin.py, embryo of routing
driven placement.
* Change: In boostrap/ccb.py, change the devtoolset argument from a fixed
behavior "--devtoolset-2" to a selecting one "--devtoolset=X" where X
is the requested version of the devtoolset.
Modify coriolisEnv.py to dynamically detect with which devtoolset
we have been compiled. Idem for Makefile.package and
FindBootstrap.cmake.
* 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: As, starting from version 5.8, LEF/DEF parser/drivers are
availables under Apache 2.0 license, integrate them inside the
project. Rewrite the Makefiles into CMakeLists.txt, build only
the C++ version. Create an entry for the LEF/DEF doc in the
documentation.
* New: In documentation, reorganise all the various documents into one
Sphinx coherent one. The index also provide a link toward the
Doxygen generated doc (C++ APIs) and the venerable LaTeX2HTML ones
(for Stratus).
This will make easier all future extensions to the doc corpus.
The generated documentation is commited into Git so a new user
can use it directly after cloning the repository.
The HTML doc is truly generated by Sphinx, but the pdf one is
created rst2latex. The Sphinx pdf writer is buggy when a "tabular"
contain a multicol and a multirow in the same area of the table.
rst2latex handles it correctly.
We use a theme borrowed for Read The Doc (half of it).
It seems that some Javascripts are not working correctly,
namely the folding of the navigation sub-menus and the index
generation and search mode.
* 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.
* 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.
* 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: coriolis2.spec.in, Makefile.package and Builder/ccb now support
RHEL6, RHEL7 & Fedora.
* Change: In Bootstrap, added a flag to activate compilation with
openmp.
* Bug: In Bootstrap, in coriolisEnv.py, check if devtoolset-2 is already
active before launching it as a sub-shell.
* Bug: In Isobar, In PyHurricane.h, DBoDestroyAttribute() set the proxy
pointer toward the C++ object to NULL. So when the Python object is
deleted no double-deletion occurs on the C++ object.
Add some more trace information in Python link/dealloc.
* Change: In CRL Core, in cyclop, make CMakeLists.txt automatically
choose the right rule for linking the binary wether we use Qt 4 or
Qt 5. Very irksome problem.
* New: In EtesianEngine::addFeed(), do not take into account instances
that are not placed entirely inside the top cell abutment box (was
causing a core dump).
* Bug: In Katabatic, in GCellQueue, correct a mismatch between a GCell
set and the iterators used upon it.
* Bug: In Mauka, in Row & Surface correct a mismatch between a container
and it's iterator.
* New: In Etesian, updated to work with the latest Coloquinte, patch
contributed by G. Gouvine.
Added EtesianEngine::setDefaultAb() to compute an abutment box if
the Cell is completly unplaced.
* New: In cumulus, in ClockTree, now the placer can be configured to be
either Mauka (slow simulated annealing) or Etesian (fast analytic).
New setting 'clockTree.placerEngine' in plugin settings.
* New: In Bootstrap, in Builder & coriolisEnv.py support for RHEL7/SL7.
The sub-directory name is 'el7_64'.
In qt_setup() add QtSvg to list of Qt5 & Qt4 used libraries.
* New: In Hurricane, In Cell add a placeholder for flags. First use to
store whether the Nets have been transhierarchically flatteneds.
* New: In Hurricane, In NetRoutingState add an Unconnected flag for
more accurate diagnosis.
* New: Hurricane, in CellViewer add an entry menu for stress tests.
The script must be named "stressScript.py" in the cwd.
* Change: In CRL Core, in display.conf add a scaling parameter for the
display threhold of the layer. This way we can adapt to different
standard cells height.
* Change: In CRL Core, in ISPD05 bookshelf loader, use the pitch of the
cell gauge instead of a hard-wired 5.0.
* Change: In Cumulus, in ClockTreePlugin, add support for Etesian placer
and a new configuration parameter to choose between Mauka/Etesian.
* New: In Etesian, support for the latest Coloquinte.
Add feed insertion stage.
* Bug: In Kite, In BuildPowerRails, check that _ck is not NULL before
tring to access it's name...
* Change: In Kite, check if the Cell has it's Nets flattened before
doing it (or not).
* Change: In Bootstrap, in FindBoostrap.cmake, install in system-wide
directories /etc or /opt only if the the installation path is
exactly /usr or /opt and not only beginning with it.
* 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.
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.
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.
