Jean-Paul Chaput f1668cec5f Disable BFD support by default.
* Change: In <tool>/CMakeLists.txt, add an USE_LIBBFD option to
    enable the link against the BFD library. Latest versions seems
    to have changed their API.
* Change: In bootstrap/ccp.by & builder/Builder.py, add an option
    "--bfd" (and self._bfd) to enable BFD support.

Jean-Paul Chaput c6e5583233 Documentation cleanup & rebuild.
* Change: In documentation/build.py, more PEP8 & Python 3 future compliance.
    Correct copy of the tools HTML docs on my laptop, to have a full
    offline copy of the doc.
* New: In documentation/contents/pages/check-toolkit, duplicate the doc
    from alliance-check-toolkit README. Seems it has been inadvertently
    removed at some point (?). Have to be careful to maintain in synch
    with the toolkit.
* Change: <tool>/doc/*/SoC.css, use Roboto fonts when availables.
* Update: Commit the whole pre-generated docs (Doxygen, Pelican).

Jean-Paul Chaput 5d891b2cd8 The VST driver is now allowed to preserve the case of identifiers.
* New: In CRL::NamingScheme, add a flag VstNoLowerCase, and its
    management it in the Verilog to VHDL converter.
* Change: In CRL::BlifParser::Model::toVhdlModels(), disable the
    lowercasing of identifiers. We shouldn't apply Alliance VHDL
    subset constraits when reading blif files. So we will see
    uppercase identifiers in Coriolis.
* Change: In CRL::VstParser, no longer lowercase identifiers that
    are *not* VHDL keywords. Uppercases are legals in VHDL...
* New: In CRL::Catalog::State, add a new flag VstNoLowerCase to
    tell if the VST driver should keep the uppercases.
* Change: In CRL::VhdlEntity, add a VstNolowerCase flag to disable
    the lowercasing.
* Change: In CRL::vstDriver, lower case the file name if needed.
    remove the previously opened filename if it differs from the
    lowercased one.
* Change: In UnicornGui CTOR, disable VHDL enforcement for the
    Blif parser.

Jean-Paul Chaput 3dbaea6aca Bug fix, restore the FreePDK 45 (real) support.
* Change: In CRL::LefParser::_macroCbk(), create a Catalog entry for the
    newly read MACRO (that is Cell) and sets the Logical, Physical,
    InMemory and TerminalNetlist flags.
* Bug: In CRL::LefParser::_siteCbk(), check for NULL cell gauge.
* New: In CRL::AllianceFramework, add setCellGauge(), to set the default
    cell gauge. Exported to Python.
* Change: In CRL/etc/common/technology.py, create variables for VIA
    layers, so we can modify their properties afterwards.
* New: In CRL/etc/node45/freepdk45, port the configuration files to the
    new Python "importable" format.
      Note: in kite.py, all the gauges (Routing & Cells) must be named
    "LEF.CoreSite" to please my LEF parser, so it can match the gauge
    name with the SITE name for standard cells.
* Bug: In Anabatic::NetBuilderVH::_do_2G(), forgotten to be reimplemented
    from the base class. Simply redirect to _do_xG().
* Change: In Katana::PowerRailsPlanes::PowerRailsplanes(), create plane
    from the layers in the RoutingGauge and their associated blockages
    instead of sweeping through all the basic layers.
      Allow to distinguish bewteen "METAL" (symbolic) and "metal" (real).

Jean-Paul Chaput 7e7e7170ba Improve symmetry management for analog designs.
* Bug: In Hurricane::NetRoutingState::getSymValue(), outrageously bad
    computation of the symmetric coordinate when the value was superior
    to the axis... (shame on me).
* Change: In Anabatic::Disjkstra::load(), for symmetrically paired nets,
    check that the axis of symmetry is *outside* the searchArea.
      Otherwise, the two mirrored areas overlaps and the two nets will
    unescapably be on top of each other. Issue a warning but still
    continue.
* Change: In Anabatic::Vertex::isRestricted(), allow perpandicular
    wire to go through struts or thin (less than one routing pitch)
    node. May have to recheck in the future and restrict to struts
    only.
* Bug: In Bora::HVSlicingNode::updateSymNetAxis(), rescursive call in
    child node was not systematically done (bad curly brace position).
      Also checks that symmetries are not empty before accessing the
    front element (one less core dump).

Jean-Paul Chaput a50b6ce317 More PEP8 compliant Python code. Start rewrite Python/C++ wrappers.
* 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.

Jean-Paul Chaput 837de500aa Compliance with Debian 10 Buster.
* 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.

Jean-Paul Chaput 0dc98dfce3 Migrating doc from Sphinx towards Pelican.
* 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.
2020-02-03 17:44:15 +01:00
Jean-Paul Chaput e711ce8dd2 More configuration parameters for P&R Conductor, for experimenting.
* 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.

Jean-Paul Chaput 68e45bc5ab Groudwork for routing density driven placement. Compliance with clang 5.0.1.
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.
2019-12-09 01:57:44 +01:00
Jean-Paul Chaput 39cd831a57 Added message when loading the technology/configuration files.
* New: In CRL/python/helpers.io, vprint() wrapper around print to display
    messages according to the verbose level.
      In etc/*, add messages in every configuration files so we may know
    under which we are running.
2019-11-15 14:40:59 +01:00
Jean-Paul Chaput 2c73cfe76c Migrating the initialisation system to be completely Python-like.
* New: In bootstrap/coriolisEnv.py, add the "etc" directory to the
    PYTHONPATH as initialization are now Python modules.
* New: In Hurricane/analogic, first groundwork for the integration of
    PIP/MIM/MOM multi-capacitors. Add C++ and Python interface for the
    allocation matrix and the list of capacities values.
* Change: In Hurricane::RegularLayer, add a layer parameter to the
    constructor so the association between the RegularLayer and it's
    BasicLayer can readily be done.
* Change: In Hurricane::Layer, add a new getCut() accessor to get the
    cut layer in ViaLayer.
* Change: In Hurricane::DataBase::get(), the Python wrapper should no
    longer consider an error if the data-base has not been created yet.
    Just return None.
* Bug: In Isobar::PyLayer::getEnclosure() wrapper, if the overall
    enclosure is requested, pass the right parameter to the C++ function.
* Change: In AllianceFramework, make public _bindLibraries() and export
    it to the Python interface.
* Change: In AllianceFramework::create(), do not longer call bindLibraries().
    This now must be done explicitely and afterwards.
* Change: In AllianceFramework::createLibrary() and
    Environement::addSYSTEM_LIBRARY(), minor bug corrections that I don't
    recall.
* Change: In SearchPath::prepend(), set the selected index to zero and
    return it.
* Change: In CRL::System CTOR, add "etc" to the PYTHONPATH as the
    configuration files are now organized as Python modules.
* New: In PyCRL, export the CRL::System singleton, it's creation is no
    longer triggered by the one of AllianceFramework.
* New: In CRL/etc/, convert most of the configuration files into the
    Python module format. For now, keep the old ".conf", but that are no
    longer used.
      For the real technologies, we cannot keep the directory name as
    "180" or "45" as it not allowed by Python syntax, so we create "node180"
    or "node45" instead.
      Most of the helpers and coriolisInit.py are no longer used now.
    To be removed in future commits after being sure that everything
    works...
* Bug: In AutoSegment::makeDogleg(AutoContact*), the layer of the contacts
    where badly computed when one end of the original segment was attached
    to a non-preferred direction segment (mostly on terminal contacts).
      Now use the new AutoContact::updateLayer() method.
* Bug: In Dijkstra::load(), limit symetric search area only if the net
    is a symmetric one !
* Change: In Katana/python/katanaInit.py, comply with the new initialisation
    scheme.
* Change: In Unicorn/cgt.py, comply to the new inititalization scheme.
* Change: In cumulus various Python scripts remove the call to
    helpers.staticInitialization() as they are not needed now (we run in
    only *one* interpreter, so we correctly share all init).
      In plugins/__init__.py, read the new NDA directory variable.
* Bug: In cumulus/plugins/Chip.doCoronafloorplan(), self.railsNb was not
    correctly managed when there was no clock.
* Change: In cumulus/plugins/Configuration.coronaContactArray(), compute
    the viaPitch from the technology instead of the hard-coded 4.0 lambdas.
      In Configuration.loadConfiguration(), read the "ioring.py" from
    the new user's settings module.
* Bug: In stratus.dpgen_ADSB2F, gives coordinates translated into DbU to
    the XY functions.
      In st_model.Save(), use the VstUseConcat flag to get correct VST files.
      In st_net.hur_net(), when a net is POWER/GROUND or CLOCK also make it
    global.
* Change: In Oroshi/python/WIP_Transistor.py, encapsulate the generator
    inside a try/except block to get prettier error (and stop at the first).
2019-10-28 18:09:14 +01:00
Jean-Paul Chaput 5bbeb0b062 Support for separated NDA tree. Big cleanup of the Python init system.
* Change: In Hurricane::Script, when running a script, no longer do it
    inside a Python sun-interpreter, use the current one. This way we
    no longer have our modules initialized twice or more, which was
    starting to be unmanageable (with the NDA support).
      The settings were re-read multiple time to the same value, so it
    was working, but still...
      I hope I didn't left some dangling Python objects now.
* Bug: In Hurricane::LayoutGenerator::drawLayout(), get the device abutment
    box though a Pyhon object *before* finalizing which removes that objet.
* New: In cumulus/plugins/__init__.py, add a "loadPlugins()" and static
    initialisation to preload plugins modules.
      We use that pre-loading step to append to the module __path__ attribute
    the alternate directory where a NDA covered may be found. This assume that
    the directory tree under the NDA root is identical to the one under the
    public root.
* New: In cumulus/plugins/chip/__init__.py, small utility function
    importContants() to import the constants inside another module namespace,
    to have more consise notations.
* Change: In cumulus/plugins/, in the various plugins sub-modules import
    use the full path from plugins, that is, for example:
      from plugins.core2chip.CoreToChip import IoPad
* Change: In Unicorn/python/unicornInit.py, no longer directly load the
    plugins modules, this is now done by cumulus/plugins/__init__.py.
      Instead, iterate through sys.modules for the ones starting by "plugins/"
    and try to execute a Unicorn hook, if present.
* Change: In Karakaze/python/AnalogDesign.py, update for the new Instance.create()
    prototype (added placement parameter).

Gabriel Gouvine f1644fc229 Workaround to get the ISPD benchmarks working 2019-10-06 12:58:33 +02:00
Jean-Paul Chaput 91f973c00f Improve the management of the I/O pad near the chip corner.
* Bug: In cumulus/plugins/PadsCorona.py, when a pad is at the beginning
    or at the end of the side, the pad corona terminal may be outside
    the corona range (not directly facing it). In that case, create a
    bend to reach it.
      Worse, in some case more than one (but likely no more), could be
    in that case, so not only do we create a bend but also make a
    shift in the bended segment so two consecutive ones are not on the
    same axis, causing shorts.
      If both end pads of a corner are in that case, we cannot prevent
    a short, so at least, issue a warning.
* Bug: In CRL::Vhdl, the Entity::VstUseConcat was not passed correctly
    along, so we did get a strange mix of conat and direct assignment.
* New: In Unicorn/cgt.py : added --vst-use-concat options to control
    the VST driver behavior.

Jean-Paul Chaput 0df4821806 Full update of the generated documentation for version 2.3 2019-05-27 18:49:51 +02:00
Jean-Paul Chaput 4cd0bcb009 Various bug corrections to pass the alliance-check-toolkit reference benchs.
* New: In Isobar::PyCell, export the isRouted() and setRouted() to the
    Python interface.
* Bug: In CRL::Entity::parseEntity(), check that the closing parenthesis
    is the last character of the net name. Issue a more relevant error
    message.
* In Anabatic::NetBuilder::_do_xG() and all other unimplemented methods,
    throw an error if called from a derived classes instead of just
    issuing a message in the debug stream. Avoid later core dumps...
* In Anabatic::NetBuilderHV, implement the builders for GCells with
    one pin. Needed to support chip/corona routing.
* Bug: In Cumulus/plugins/Chip.py, check that coronaCk exists before
    using it.
* New: In Cumulus/plugins/PadsCorona/Side._placePad(), when routing
    a design with symbolic pads, export the chip external "pad"
    connectors to be able to perform a lvx (otherwise cougar do not
    create external nets).
      In Corona._createCoreWire(), set the minimal gap between the pads
    and the corona to 6 pitches. Empirical value to avoid DRC errors
    with symbolic pads (pxlib).
      When successufully done, mark the Corona cell as routed.
* Bug: In Cumulus/plugins/Core2Chip.IoNet, the regex for vectorizet net
    was wrong, it was allowing only one digit in the index.
* Bug: In Cumulus/plugins/Core2Chip.cmos, correct management of
    pad & corona clock nets. Correct connexion between vdde/vddi.
* Bug: In Unicorn/cgt.py, forgot to execute scripts when in text mode.
2019-05-24 23:57:22 +02:00
Jean-Paul Chaput 3fb746fbef Support for mixing real pads & symbolic core. Wrapper around s2r.
* 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...
2019-05-22 14:34:32 +02:00
Jean-Paul Chaput f6c840fd59 ISPD05 loading speed issues. IO PAD support for LEF importation.
* New: In Hurricane::IntrusiveMap, introduce IntrusiveMapConst which allow
    to search with a "const Key&" instead of a "Key", sparing the copy
    construction of the Key.
* Change: In Hurricane::Cell::NetMap, use the new kind of map with
    "const Name&" key access. This speeds up the Cell::getNet() method
    by suppressing one copy construction of a Name, which are costly
    after all...
      Should review the whole code to use "const Name&" everywhere it
    is possible.
* Change: In Hurricane::Entity & Hurricane::DBo, displace the unique
    identifier from Entity to DBo (move up to the base class).This
    to allow us to build deterministic map of DBo requireds in
    UpdateSession (which is built upon a SharedProperty).
      WARNING: This break the JSON database exportation support, do not
    use it until fixed/rewritten.
* Change: In Hurricane::Layer, add an attribute to know if a layer is
    associated to a blockage. Modificate accordingly PyLayer and
    BasicLayer.
* Change: In Hurricane::SharedProperty, the set of owners (DBo*) is now
    stored in a std::set sorted on the objects Ids, instead of a simple
    vector. The linera search time through the std::vector was starting
    to show (ISPD05 bigblue1).
* Bug: In Isobar::PyInstance, make full contructor signature (5 arguments)
    conform to the C++ one. It was only accepting the four first and
    forcing the placement status to be FIXED.
* Bug: In CRL/etc/symbolic/ispd05/kite.conf, update for the new configuration
    requirements where all distance must be converted into DbU in the
    file itself (use "helpers.l()", "helpers.m()"). Apply to the cell &
    routing gauges.
* Bug: In CRL/etc/symbolic/ispd05/technology.conf, update for the new
    configuration. "helpers.initTechno()" *must* by called first thing
    in this file in order for the Technology to be created.
* New: In CRL::AllianceFramework, add matchCellGauge() &
    matchCellgaugeByHeight()
* New: In CRL::CellGauge, add a flag to distinguish gauges meant for
    IO Pads and an "isPad()" predicate.
* Change: In CRL::Ispd05Bookshelf, flush the UpdateSession stack every
    1000 elements additions. Maybe not necessary now the the UpdateSession
    property relies on a std::set instead of a std::vector.
* New: In CRL::LefImport, support for SITE and match/create the appropriate
    CellGauge on the fly. Specific support for MACROS that are flagged PAD.
      Add a dedicated post-treatment for PAD connectors, extend them toward
    the boundary of the nearest abutment box side. Tested only on AMS 350nm
    c35b4 for now.
      This part is most likely to be tweaked for every kind of real foundry
    pad that we may encounter...
* Change: In EtesianEngine::findYSpin(), use the C++ "for" construct to loop
    over Collections.
* Change: In Unicorn/cgt.py, register the Python/C++ tutorial support by
    default.
2019-04-22 12:16:16 +02:00
Jean-Paul Chaput 0b605000ed Bug fixes in Blif parser (no VHDL enforcement) & GDS driver.
* Bug: In Hurricane::DrawingQuery::drawGo(), forgot to apply translation
    on Polygon and Rectilinear.
* Bug: In Hurricane::Rectilinear, forgot implementation of getContour().
    Add a new accessor getPoints().
* Bug: In CRL::Blif::load(), do not always enforce translation towards
    VHDL names. When loading LEF+gds it may change the Cell names between
    the two stages so the gds layout do not get added to the LEF Cell
    phantom.
      Now add a boolean enforceVhdl argument (may be a flag in the future).
* Bug: In ::GdsStream::operator<<(Cell*), forgot to drive the Rectilinear.

Jean-Paul Chaput 57d52023e1 Command line support for Katana in cgt.
* New: In Unicorn/cgt.py, add "-K" option to use Katana for global and
    detailed routed (in place of Knik/Kite).
      Comment the preroute stage to ensure determinism (I often forgot
    to run this stage while in graphic mode).
2019-02-26 20:09:26 +01:00
Jean-Paul Chaput 6fd383ad51 Make FLUTE an independant tool in the Coriolis git repository.
* 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).
2019-02-12 12:48:52 +01:00
Jean-Paul Chaput fcd6d69a2f Analog integration part II. Analog place & route (slicing tree).
* Change: In Hurricane::CellWidget, set the minimal size to 350 pixels
    to fit my normal DPI secondary screen...
* Change: In Hurricane::Error(), reactivate the backtrace generation by
    default. Seriously slow down the program each time an Error is to
    be constructed.
* Bug: In Analog::Device::preCreate(), check for NULL Technology before
    attempting to use it.
* Change: In Hurricane/Analog, remove all '*Arguments*' classes and their
    Python interface. It was an obsoleted way of passing devices parameters
    to the Python layout generators (located in Oroshi). Now we just get
    them straight from the Device with the getParamter() method.
* Change: In CRL::System CTOR, add Python pathes for Oroshi & Karakaze.
* Change: In Oroshi/Python/WIP_*.py layout generator scripts, remove
    all uses of the "Arguments". Directly access the parameters through
    the device itself. Make the checkCoherency() with identical arguments
    as of layout().
* New: Bora tool that performs analog place & route. Based on a slicing
    tree representation. It is the thesis work of Eric Lao.
      Code beautyfication and some programming cleanup.
* New: Karakaze tool, provide the Python base class AnalogDesign used
    to build an analog design. Create/configure devices and assemble
    them in a slicing tree.
* Change: In Unicorn/cgt.py, display the stack trace in case of an
    ImportError exception as well as for other exceptions.
      Add Bora to the set for included tool engines.
2018-10-18 18:10:01 +02:00
Jean-Paul Chaput 3f73b9d033 Anlog integration part I. Atomic devices support (transistors).
* Change: In boostrap, remove support for Chams.
* New: In Hurricane::Technology, added support for DTR rules, UnitRule,
    PhysicalRule and TwoLayersPhysicalrule. Added devices descriptors and
    models descriptors (for Spice). Spice description is not used yet
    but kept anyway in case of future use.
* New: Hurricane::Analog whole library and it's Python interface. This
    provides support for transistors, capacitors and resistors. Only
    transistor support is fully implemented as of now.
* New: In CRL/python/coriolisInit.py, read configuration files for the
    Analog extension (analog.conf & devices.conf). Thoses are optionals
    and a simple warning is issued if not found.
      Added helpers/AnalogTechno.py DTR loading helper.
      Add analog configuration files for 180/scn6m_deep_09.
* New: Oroshi tool that provides actual layout drawing for transistors.

Jean-Paul Chaput 767407736d Add a fully generated documentation in the git repository.
* Change: In all tools supplying documentation, as we use some specific
    software to create the doc, they may not be available, or worse, be
    and incompatible version. So, by default, we install the files shipped
    with the git repository. To force a full doc rebuild, use the "--doc"
    flag of ccb.py.
2018-06-06 18:42:26 +02:00
Jean-Paul Chaput 4a65a8d4e7 Added GDSII driver. Bug in Blif parser.
* New: In CRL, implement a true GDSII driver. The driver is directly under
    CRL and do not use an intermediate structure in vlsisapd. The ASCII
    GDSII is removed.
      Huge polygons are not supported yet. Have to be split up in
    sub-polygons of less than 4000 vertexes.
      Symbolic layout can be exported to give a rough idea of the layout
    but RDS expension is not applied. Symbolic composite layers are
    expansed into their basic layers so the design *looks* normal.
* Deprecated: In CRL, remove all traces of the old XML configuration
    parsers. No one needs them now, including Chams.
* Bug: In CRL::BlifParser, before blindly loading the model of a subckt
    from disk with AllianceFramework, checks if it is in the Catalog
    first. Load with AllianceFramework only cells that are in the
    Catalog.
      This prevent a file of the same name than a model to be loaded
    shadowing the later defintion of the model in the Blif file.
      All this is due to the fact that Blif could be non-ordered for
    the models...
* Change: In Hurricane::BasicLayer, the "extract number" is replaced
    by a GdsLayer and GdsDatatype to generate accurate GDS files.
    Even if datatype is 0 most of the time.
      Update all the "technology.conf" files in CRL to provide those
    two numbers.

Jean-Paul Chaput 2b3b847162 New LEF importer for real technologies.
* New: In CRL Core, added LEF importer for real technologies. This is
    still a work in progress. Exported in Python interface.
* Bug: In CRL Core, CellGauge::getRecord() correctly display DbU
    attributes.
* Change: In Unicorn, mofificate ImportCell and ImportCellDialog to
    support the LEF importer. Add a template layer so we can work with
    loaders returning Cell* or Library*.
* Change: In Unicorn::UnicornGui::getCellFromDb(), in addition to the
    Alliance loader, uses the DataBase::getCell() too (for Cells that
    are *not* in Alliance).

    been made to look like a gdb trace.
* In Unicorn, cgt.py, use showPythonTrace().

Jean-Paul Chaput c44c6b13f3 Adjust Katana event sort. CMake detection of Python 2.7 only.
* Change: In all top CMakeLists.txt, force the use of Python 2.7 as
    we do not compile against 3.x flavors. Do not use the "EXACT"
    flags as it will not recognize 2.7.x versions.
* Change: In Katana::RoutingEvent::Key::Compare(), preliminary
    experiments shows that the best sorting order is:
      - Lower layer first (i.e. M2 -> M3 -> M4 -> ... )
      - Longer segments first.
      The later seems to be counter-intuitive. Guess is that placing
    the small ones first generate a more important fragmentation of
    the big ones. They are placed too early and are difficult to move
    afterwards.
      Another feature to test is *not* inserting pushed left/right
    segments if they are not *already* routed.
* Change: In PyKatanaEngine.runNegociate() now takes a flag argument,
    provided through the new PyKatanaFlags exported object.
    (doChip.py must be changed accordingly)
2017-05-11 17:26:56 +02:00
Jean-Paul Chaput bdc474d7fc Quieter helpers initialisation, isderived() alternative to isinstance().
* New: In CRL.python.helpers, all methods make use of the quiet mode to
    allow completly silent initialisation.
      Introduce isderived() function to check the derivation relationship
    of two C++ encapsulated classes by Isobar. The Python isinstance do
    not work, all C++ wrapped classes are of the base type 'type'.
    isderived() uses the MRO mechanism (Method Resolution Order) as a
    workaround. I can't find in the documentation if it's the expected
    behavior or if i did miss something in when building my classes.
2016-12-12 17:06:53 +01:00
Jean-Paul Chaput 8376d0c209 Remove GraphicAnabaticengine, temporarily made for debugging.
* Change: In Anabatic, remove GraphicAnabaticEngine, PyGraphicAnabaticEngine,
    PyAnabaticEngine (but keep PyAnabatic for constants exportation)
    and GlobalRoute (moved to Katana). Drawing methods for Edge & GCell
    are moved into GraphicKatanaEngine.
2016-09-07 11:21:36 +02:00
Jean-Paul Chaput 48f3a2bc3c Anabatic transient commit 18. Port of Kite (Katana), Yeah, Baby! Yeah!
* 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-).
2016-08-15 16:30:13 +02:00
Jean-Paul Chaput 3835d6f7ad Diplay function, file & line number in the backtrace (like gdb).
* 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.
2016-08-06 18:15:06 +02:00
Jean-Paul Chaput 601e3d3da1 Anabatic transient commit 8. More Dijkstra bugs correcteds.
* 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.

2016-06-11 21:58:25 +02:00
Jean-Paul Chaput f68ac4d0e6 Argh. cdebug was slowing down the program too much.

    down the program (three times for Kite!). Create a macro cdebug_log
    which calls cdebug *only* if the debug level is active.
2016-06-11 21:56:12 +02:00

    yet in the devel branch.
* Change: In Hurricane, in Commons.h, in the vector slot template, start
    index at 0 and not 1 (to closer to the internal representation).
* Change: In ExtensionGo, forgotten trace system calls to update.
2016-05-23 16:02:57 +02:00
Jean-Paul Chaput 82cff69d9f Complete rewrite of the trace system (now a stream).
* Change: In Hurricane, in Flags add operator overload for "int" type
    and not only "unsigned int". Otherwise the compiler complaints about
    ambiguous overload when using enum values which are considered as
    "int".
      Simpler code for the BaseFlags::contains() method.
      Added implicit conversion from BaseFlags toward bool type.
* Change: In Hurricane, in Commons, complete replacement of the previous
    two trace systems (trace & ltrace) by a stream-based one.
    As it is a true object it is much less fragile than the one based
    on defines (but maybe a little slower).
      Define a reservation table for the trace levels for all the
    Coriolis & Chams components.
* Change: All tools, use the new trace system.
