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.
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.
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.
- 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.
- Bug: In CMakeLists.txt, when our custom macro "setup_boost()" is used,
do not call find_package() afterward, it corrupt the library pathes
from '/usr/lib/' to '/usr/lib/lib/'.
- Bug: In Histogram::addSample(), reject the sample if iset is superior
OR EQUAL to the sets size...
- Change: In etc/mauka.conf, sets "mauka.standardAnnealing" to True. Otherwise,
when hMetis (4-part) is not used, this leads toward very poor placements.
- New: In UsersGuide, add a third style variant for the soc-extras site.
- 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: In GraphicsParser, read the new darkening scheme (HSV ratio).
"display.xml" configuaration file modificated accordingly. May be some
tuning needed for white background styles.
- New: Histogram object, imported from Kite. Made more generic to be reusable
by all.
- Change: In Measures, added Inspector support.
NOTE: The hidden property holding MeasuresDatas no longer uses a pointer
a value. This forces us to enable the copy constructor. It is needed
for some inner STL container manipulation, but should *not* be used
with non-empty datas. The copy constructor *do not* copy the internal
datas (reset the object).
- New: In Measurments, support for complex data sets, saved in separate Gnuplot
<.dat> files. Used to integrate Histogram.
- New: In Histogram, now a supported Measure type so it can be integrated along
all others measurments.
- Bug: In display.xml, forgotten gcut description in Alliance Classic black
style.
- Change: Rename "obstacle" to "blockage" in all the places it still appears
to be completly homogeneous.
- New: In Catalog, adds a "Pad" attribute to mark cells that are pads.
- Change: In ApParser, discard "padreal" instances as a cause for a Cell to
be non-terminal. This is for LeafPlugOccurrences to consider the terminals
of those cells.
- Change: In ApParser, makes use of the new Pad flag in Catalog.
- 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 AllianceFramework constructor, now look for an XML configuration
file in the current directory (<cwd>/.environment.alliance.xml).
- New: DefParser, DefDriver & LefDriver are replaced by DefImport, DefExport
and LefExport (resp.). LEF/DEF parser/driver are no longer integrated
in among Alliance ones due to too much difference in data organisation.
Instead they are build as Import/Export utilities.
- New: Iccad04Lefdef import the ICCAD'04 benchmarks into the SxLib format
suitable for Knik/Kite. They are derived from the ISPD'98 (ibm01--ibm18)
benchmarks. Many corrections are applieds to ensure a more realistic
representation.
Generate a new library from the LEF file "on the fly".
- New: Ispd04Bookshelf import the ISPD'04 benchmarks in SxLib from bookshelf.
Thoses benchmarks can be placeds whith fastplace. Unfortunatly fastplace
do not manage blocks and reduce them to standard cell which is not
usable for detailed placement. Too bad, the parser exists still.
Make uses of the new vlsisapd/bookshelf parser. A whole library is
generated "on the fly" on the basis of "one node, one Cell" (so we have
a bijection between Cell and Instance). The result of this parsing is
different from the one of the stand-alone ispd04 binary in the sense it
fits the circuit to the SxLib gauge thus changing the routing capacity:
from 16 to 20.
- Change: In ApDriver, the lookup modify the lookup table for matching
Alliance layers against Hurricane ones, "OBSTACLEx" became "BLOCKAGEx".
- Change: In default <enviromnent.alliance.xml> adds the name of the
blockage net: "^obstacleNet$". Some work over the coherency of the
blockage managment remains to be done.
- Change: In AllianceFramework, partial rewrite of the get/creation of
AllianceLibrary to fit the requirements of the "on the fly" generation
from the benchmarks loaders. And correct some bugs by the way.
- Change: In Environment, suppress any reference to LEF technology as LEF/
DEF is now used as import/exports.
- Bug: In VstDriver, perform only one lookup for global signals among all
nets and not for each instance master cell. That was making the driver
quadratic! Now it's linear and reasonably fast.
- 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: In PaletteWidget, uses "goMatched" to hide DrawingStyle that are
not associated to a Go to hide/show. That is, are only pure color useds
by ExtensionGo.
- 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.
- 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 AllianceFramework, do not try to build SxLib gauge if the layers are
not presents. Prevent cgt to miserably fails if the environment is not
found.
- Change: In src/ccore/CMakeLists.txt, try to guess the CORIOLIS_TOP from the
compilation environment and pass back to sources.
- Change: Rename hcmos9 into cmos130 in configuration files.
- New: Adds a README.tex describing the essentials features of Coriolis2.
- New: Support for LaTeX in CMake through the macros supplieds by Sandia.
- Change: Adds support for installation of config file in system-wide
/etc.
- Change: adopt a tree layout compliant with the UNIX FHS.
* includes under TOP/include/coriolis2.
* shared datas under TOP/shared/coriolis2.
* docs under TOP/share/doc/coriolis2.
* configuration under TOP/etc/coriolis2
* ./crlcore:
- Change: In Environment, comply to the new tree layout, search configuration
files under TOP/etc/coriolis2/.
* ./knik:
- Change: In flute, comply to the new tree layout, get the "POW*.dat" files
from TOP/share/coriolis2/flute-2.4.
- Change: In the CMakeLists.txt, in all the install commands remove all
the leading "/" as they prevents the CMAKE_INSTALL_PREFIX to be took
into account. It was nevertheless working because buildCoriolis.py was
using DESTDIR which is prepended anyway.
* ./goodies:
- Change: In buildCoriolis.py, no longer uses the DESTDIR but instead
CMAKE_INSTALL_PREFIX.
- Cleanup: No longer import the std namespace in headers.
- Bug: In Measures.h, incoherent prototyping of getMeasure() template.
- Change: In Environment, SearchPath & the XML format, slight change to
allow overwriting of Alliance library pathes. Instead of having an
attribute on the <system> node that applies to all libraries, we
have a "mode" attribute in each <library> node.
"mode" can takes three values:
1. - "append" : the library path is added in tail of the list.
2. - "prepend" : the library path is added in head of the list.
3. - "replace" : if the library already exists in the pathes,
this ones replaces it, whitout modifiying the order.
If it doesn't exists, it simply appended.
The "replace" mode is the one to be used if a users wants to shadow
system libraries by his own versions (sets in ~/.environment.alliance.xml).
- Change: In ToolEngine, adds a static method "destroyAll()" that must be
called *before* the Hurricane database destruction. This is to avoid
a mis-oredering in destruction.
ToolEngines are stored in a property, property are part of the DBo
base object so are destroyed *after* the Cell derived object has been.
Thus ToolEngine are deleted *after* the Cell components and if they
still refers to it, we are doomed.
- Change: In display.xml, color support for displaying references.
