* New: In Hurricane, dedicated class BaseFlags to wrap a set of flags.
Similar to the Mask class, only with a slightly different semantic.
Encapsulation of <unsigned int>.
Also provide support for the Inspector, to have a human-readable
display of the flags.
* Change: In Hurricane, in Cell, regroup all the flags under a Flags
sub-class of Cell. No more mixing between booleans and bit flags.
(first use of BaseClass).
* In Hurricane, CRL Core & Knik, many small corrections to suppress
annoying warning messages at compile time.
Most noticeably, Bison errors in VstParserGrammar generated by
rules and token with mismatched return value type. This was not
problematic because the badly defined return value where not used.
But still...
* New: In CRL Core, created a LibraryManager widget. It provides a
composite information based on what is present, for each
Alliance library:
1. - A Cell in memory, without Catalog::State.
2. - A Catalog::State, with or whithout the Cell in memory.
3. - The files of the Cell in the librariy's directory.
4. - A file with a format referenced for one of the importers.
File type recognition is based *only* on the file extension,
so it may easily confused. Be careful about what you put in
the library's directory.
One of the big limitation is that it will not display Hurricane
libraries that do not have the AllianceLibrary extension.
This widget is put in a separate library <libmanager>, included
in the default CRLCORE_LIBRARIES.
* Change: In CRL Core, in State (through the loader), now sets the
InMemory flag (event if nobody uses it yet...). Display it in
the state _getString().
In AllianceFramework, new getAllianceLibraries() method.
In CatalogExtension, make the static method "get()" publicly
accessible, for sometimes we want the whole State.
* Bug: In vlsisapd, in Path, the pathcache was not rebuild when it
should, leading to incorrect results.
* New: In vlsisapd, in Path, added a listdir() method to access the
contents of a directory and a stat() method to poll the status
of a file/directory.
Rename the ".string()" method in ".toString()" to avoid
tricky name resolution with std::string, refactor in all the
other tools.
* Change: In Hurricane, in Controller, no longer oversize the fonts
of the table's headers.
* New: In Unicorn, in UnicornGui, integrate LibraryManager.
* New: In VLSISAPD, in Configuration, add a new priority level UserFile
to distinguish between the system configuration files and the user's
configuration files (which take precedence).
* New: In Hurricane, in Script (Python), improve the API to be able
to support Chams (and remove the duplicate capability from it).
Add separate functions to perform the initialize/run(s)/finalize
cycle step by step.
* Change: In CRL Core, rename real technology <hcmos9> to <hcmos9gp>,
it's offcial name from CMP/ST. This is the 130nm.
Move the reading of the symbolic & real technologies names from
coriolisInit.py to helpers.__init__.py, to be shared with
chamsInit.py.
To avoid a clash of names inside of helpers, the two variables
of techno.py are renamed "symbolicTechnology" and "realTechnology".
Move python init system from crlcore/src/crlcore to crlcore/python.
* New: In CRL Core, In Utilities, add site-packages/pharos to the
PYTHONPATH.
* Change: In Kite, move python init system from kite/src/init to
kite/python.
* 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.
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, 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.
- 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 FreeBSD/Ubuntu patches from Otacilio De Araujo
(<otaciliodearaujo@gmail.com>).
* ./crlcore:
- New: In Utilities, cbug stream to separate all the scary messages
from Kite/Katabatic and maybe others.
- New: In stratus1.conf, adds default settings previously in st_config.
- New: Moves Python configuration helpers from under /etc/coriolis2
into PYTHON_SITE_PACKAGES/crlcore. Adapt Utilities so coriolisInit.py
is now searched in that directory. This way only true configuration
files remains under /etc/coriolis2
- Change: In helpers/__init__.py, do not try to guess the sysConfDir
when not run through coriolisInit.py. This is done by exploring the
call stack with traceback.
- Change: In ApDriver, when a physical view is driven, update the flag
in the catalog state telling that this view is present. This is far
from satisfactory as this flag should be set as soon as any physical
component is created.
- A complete sweep of cleanup to suppress allmost all compiler warnings.
* ./crlcore:
- New: Extented Python support for all objects needed to configure Coriolis.
- New: Configuration files and load helpers completly written in Python.
An XML emulation mode is still avalaible.
- New: UsersGuide, as a replacement for README, written in ReST.
- New: Start of Doxygen documentation (mostly for documenting the initialisation
objects & methods).
- New: Install a general index for the HTML documentation.
- Bug: In cyclop CMakeLists, forgot to list all the needed libraries for
the linker.
- New: Support of Python installation layout under Ubuntu 10.04.
lib/python2.6/dist-packages
- New: Inspector support enabled for AllianceFramework and most of it's
sub-objects. Attached as a property on the DataBase to be browsable
through the Inspector.
- Change: Now also read a <.coriolis2.configuration.xml> in the user's
root account (before the directory specific one and after the system-
wide).
- Change: In verbose mode, also display what environment files are being
read.
- Change: No more reference to CRL_CATA_LIB in error messages.
- Change: Suppress stratus2sxlib obsolete library.
- New: In Utilities, uses the new Backtrace to print the stack before
core-dumping.
- New: In Environment, pattern recognition of Pad model names.
- New: In AllianceFramework, pattern recognition of Pad model names.
- Bug: In Measures, add inspector support and uses pointer to prevent using
copy construction. Makes the inspector to core-dump.
- New: In RoutingLayerGauge, inspector support for Constant::Direction.
- Change: In ApDriver, correct managment of BIGVIA sizes. BIGVIA in one
metal keep their sizes, but BIGVIA whith cut must be expandeds to
contains their enclosure in metals. In Hurricane VIA size are relatives
to the cut but in Alliance, to the biggest metal.
Generate correct direction (always UP or RIGHT) for segments.
- Change: In ApParser, shrink BIGVIA to the size of their cut from the
Alliance format. Avoid VIA "bloating".
More thorough verification of Segment data coherency, mainly with
direction.
Suppress warning of non-existent logical instance in the special
case of "padreal".
- Change: In VstParserGrammar, perform an explicit plug connection on globals
Nets if the names of globals Nets differs.
- New: In display.xml, add style for printers (B&W).
- Bug: In technology.symbolic.xml, BLOCKAGE6 was associated to metal6 instead
of blockage6.
Correct extensions value for VIA metal layers above cut1.
- Bug: In Utilities, in System singleton constructor check of duplicated
type_info/RTTI initialization. Occurs when python modules are useds.
CRL must always be included first.
- New: In tools.configuration.xml, add default values for METAL minimum break
lengths.
- Change: In AcmSigda, makes the parser an autonomous one, like for ICCAD or
ISPD.
- Change: Remove AcmSigda, Bookshelf and LEF/DEF parsers from the Alliance
builtins. They are now to be used through import/export.
- Bug: In Utilities, the <misc.logMode> parameter boolean parameter was used
the wrong way (true/false).
- New: In Utilities, automatic setting of STRATUS_MAPPING_NAME. It's put
back into the environment from the configuration. This suppress the
need for the last environment variable under cgt.
- Change: New problem identified with the Python modules: each module seems
to be built as a complete binary, so all the static C++ initializers are
allocated in each module. In particular the C++ tree inheritance is built
for *each* module so we cannot longer uses the typeid() comparisons
across modules... It was used by boost::program_options to perform is
casts with boost::any and was starting throwing exceptions because of
bad casts. program_option was first initialized in "configuration"
first included by PyViewer then in PyCRL (see Utilities.cpp).
A first solution is to re-order the import of Python modules in
stratus1/st_model so that CRL is imported first.
The second is to not not link "configuration" with boost::program_option
as only the binary vlsisapd-conf-editor needs it.
That is a serious problem of which we must be aware and can cause further
strange behaviors.
Debug code used to diagnostic has been kept commented in the sources a
it may be needed again :-(
This behavior do not affect our singletons because they are part of
dynamic libraries that seems to be correctly shared between the various
Python modules.
* ./crlcore:
- In PyCRL, module method "getAllianceFramework()" moved as static object
method "get()" of AllianceFramework. Object AllianceFramework added
to module CRL.
- 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.
* ./crlcore:
- New: PyCatalog & PyCatalogState python wrappers, mainly to have constants
values for stratus1 parsers/drivers.
- 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.
* ./crlcore:
- Change: In System, static initialisation problem again, there seems to
be a race between it and boost::filesystem, make the singleton creation
"at first call" again. Triggers the System singleton creation in
AllianceFramework to spare the user the need to explicitly doing it.
- New: In Utilities, automatically adds the "site-packages" PYTHONPATH
component, guessed from CORIOLIS_TOP.
- New: In <tools.configuration.xml>, added parameters for verbosity, info
and trace level.
- New: Uniform mecanism to get the "/etc" path. Now System reads the
environment variables (thanks to boost::program_option).
- Change: In Utility, correct "when first called" initialisation of the
System singleton. Access to members only through static members that
ensure the initialisation of the singleton first.
- Change: In System, makes uses of the callback feature of Parameter to
initialize the new configuration parameters (verbosity, coredump, ...).
- Change: In linefill, build upon mstream instead of ostream. Now dual
aspect, inherit ostream and have a mstream member.
- New: "linefill" class which allows to print filled lines and automatically
go to the next line whenever the line is full (more than 80 characters).
- New: In ToolBox, getInstancesCount() recursively counts leaf cell instances.
- New: In CellGauge, added getClone() method (for Configuration).
- Change: It seems that the changes to match the new VLSISAPD weren't commited
by Damien...
- Bug: In CMakeLists.txt, local include directories *first*.
- New: In Utilities, Dots::asBool() & Dots::asLambda().
- New: In display.xml, new <drawingstyle> for Mauka Containers.
- 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.
* ./crlcore:
- New: In Utilities, The Dots class which allow nice pretty printing on
a terminal (like lines of books summaries).
./coriolis/src/crlcore,
./coriolis/src/knik,
./coriolis/src/katabatic,
./coriolis/src/kite,
./coriolis/src/equinox,
./coriolis/src/solstice,
./coriolis/src/ispd:
- 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".
