Jean-Paul Chaput 2af531991e Correct drive of the Pin in AP driver.
* Bug: In CRL::ApDriver::DumpSegments(), when saving RoutingPads build
    on Pin *not* at the top level (that is, Pin from an instance),
    use the pin's orientation to choose the segment type.
      * NORTH/SOUTH becomes a Vertical.
      * EAST/WEST becomes an Horizontal.
      Formerly, the segment direction was guessed only for the bounding
    box, leading to segments in incorrect directions leading to DRC
    errors (in nmigen/ALU16, net "b(10)").
* Bug: In CRL/symbolic/cmos/technology.py, forgotten import for
    WarningMessage.

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 dfe4d80b60 Clarify semantic of flatten Collections (walkthrough).
In the Cell/Instance hierarchy, the "terminal" and "leaf cell" concepts
where not clearly defined and partially overlapping. Now, "Terminal" is
the refer to the physical hierarchy (layout) and "TerminalNetlist" to
the logical hierarchy (netlist). The logical hierarchy can be less deep
than the physical one thanks to a Cell dedicated cell flags. Collections
related to the physical hierarchy keep their old names, the one related
to the logical hierarchy are renamed from "Leaf" to "TerminalNetlist".
The name "Leaf" was too ambiguous (leaf for *what* hierarchy).

* Change: In Hurricane::Device, set the "TerminalNetlist" flag once and
    for all. No need set it in all the derived classes again.
* New: In Hurricane::MultiCapacitor, added new parameter "dummy" to
    create dummies around the capacity matrix.
* Change: In Hurricane::Cell, remove "Leaf" related methods, replace
    them by "TerminalNetlist" one, especially Collections. Now we have
    two clear sets of Collections to walkthough the layout or the
    netlist.
      Change the "Terminal" flag into "TerminalNetlist".
* Change: In Hurricane::CellCollections, rename "Leaf" into
    "TerminalNetlist" collections and apply the new semantic to the
    locators.
* Change: In Hurricane::DataBase, Leaf to TerminalInstance renaming.
* Change: In Hurricane::DeepNet, Leaf to TerminalInstance renaming.
* Change: In Hurricane::HyperNet, Leaf to TerminalInstance renaming.
* Change: In Hurricane::Instance, Leaf to TerminalInstance renaming.
* Change: In Hurricane::Viewer::HierarchyInformations, Leaf to
    TerminalInstance renaming.
* Change: In CRL::AllianceFramework, Leaf to TerminalInstance renaming.
* Change: In CRL::Catalog, Leaf to TerminalInstance renaming.
* Change: In CRL::ApParser, Leaf to TerminalInstance renaming.
* Change: In EtesianEngine::AddFeeds, Leaf to TerminalInstance renaming.
* Bug: In EtesianEngine::resetPlacement, move there the loop over
    non terminal netlist instances to flag fully placed sub-blocks
    as terminal for the netlist. Only then remove the feed cells
    from unplaced instances. Previously, the feed cells where stripped
    even from already placed instances.
* Change: In Katana, Leaf to TerminalInstance renaming.
* Bug: In Bora::PyDSlicingNode, allow the range parameter to be the
    Python None object when we do not want to pass one but need to
    have it as positional parameter.
* Change: In Cumulus/clocktree/ClockTree.py, Leaf to TerminalInstance
    renaming.

Jean-Paul Chaput 757b95343b Support for full Database clear & restart.
* New: In CRL/etc/node600/phenitec, ported configuration of Phenitec 0.6um
    Compliant with DataBase reset.
* New: In CRL/python/helpers, added function "unloadUserSettings()" to
    unload Python modules prior to a full reset.
      Added "resetCoriolis()" to perform full DataBase reset.
* Change: In CRL::AllianceFramework, make it a derived class of DBo so
    the destroy() is now provided.
* Bug: In CRL::AllianceFramework::getCell(), do not attempt any load if
    the library list is empty. Should never occur except in case of a
    botched databse reset.
* New: In CRL::AllianceFramework, new method "saveCATAL()" to write back
    the catalog of a library and "saveCells()" to write back the cells.
      Note: only cells actually loaded in memory will be write back.
* New: In CRL::Catalog, add method "saveToFile()" to write back the CATAL
    of a library.
* Change: In CRL::ParserDriver, replace "const string&" by "string"
    (improved string support of the GNU STL).
* Change: In CRL::ParserSlot, use string instead of Name.
* Change: In CRL::ApParser, make _layerInformation an ordinary attribute
    instead of a static one. This allow for it's correct resetting
    across databas resets.
* Change: In CRL::VstParserGrammar, reinitialize Vst::framework at each
    parser call. Needed to support database reset.

* New: In Hurricane::DBo, add an object counter to be sure that when
    we perform a reset, no remaining DBo is allocated. This is different
    of the object id which is ever increasing.
      Note that, at reset, we check against "1" remaining element as at
    this point only Database is still allocated.
      Add a new "resetId()" method. MUST NEVER BE CALLED except by
    DataBase::_preDestroy().
* New: In Hurricane::Database, new clear() method to remove the Cells
    of all the libraries in reverse hierarchical depth order.
    Make use of the new CellsSort class.
* Change: In Hurricane::DataBase::_preDestroy(), call "clear()" and
    DBo::resetId().
* Change: In Hurricane::Breakpoint, change the default callback to be
    a static function. So we can restore it later.
* Bug: In Hurricane::Instance::_preDestroy(), there was yet another
    loop of deletion over a collection for the shared pathes.
      Replace it by the repetitive deletion of the first element.
* Bug: In Hurricane::Net::_preDestroy(), RoutingPads must be destroyed
    prior to any other component.
* New: In Hurricane::ColorScale, add a "qtFree()" method for freeing
    the Qt Brush, Pen & Color.
* New: In Hurricane::DrawingStyle, add a "qtFree()" method for freeing
    the Qt Brush, Pen & Color.
* New: In Hurricane::Graphics, add a "disable()" method to call the
    various "qtFree()" of the sub-objects.

Jean-Paul Chaput eab4a4aa7f In BlifParser, correct management of alias to $true/$false for terminals.
* Bug: In CRL/BlifParser::Model::mergeAlias(), when a signal is aliased
    toward $true or $false in a Blif file (through a ".name" statement),
    it was directly merged to "vdd" (resp. "vss"), and if it is an
    external signal, this leads to its removal, potentially making "hole"
    in its interface.
      Now, create a gate zero or one for each tied up/low signal. This
    way the interface is fully kept. At the cost of some supplemental
    gates.

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.

Jean-Paul Chaput eea67a9111 Added static bloat profile in Katana.
* 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.

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 9812f2fc3a Corrections to build under MacOS X. 2019-12-11 22:13:47 +01:00
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 f38945d200 Various bug fixes (Selection, Measures/Histogram, helpers).
* Bug: In CRL/python/helpers/__init__.py, in textPythonTrace(), when an
    ErrorMessage was catched, the trace parameter was not correctly
    extracted leading to an "exception in exception".
* New: In Isobar/PyCell, exported Cell::getNonLeafInstanceOccurrences()
    collection.
* New: In Isobar/PyTransformation, type is now built so the tp_compare
    is linked to the C++ operator==().
* Change: In Hurricane::SelectionModel, Hurricane::SelectionWidget and
    CellWidget, no longer use Occurrences but directly the Selector property.
      We also use the Selector to know if an Occurrence is selected by
    looking at that property on it's Quark. This avoid a very lengthy
    search in vector when there is many elements (say > 10000).
      NOTE: This is a bad implementation as there is a confusion between
    beeing selected (that is, having a Selector property attached to
    an Occurrence Quark) and being actually displayed as selected.
    This lead to awkward implatation of the various "toggle" methods.
    Have to rethink that more clearly later.
* Bug: In CRL::Histogram, the non-inline template full specialisation
    of Measure<Histogram> must not be put in the header but in the module
    to avoid multiple definition and link failure. They are actually
    real, classic functions.
2019-11-22 00:24:47 +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 92edd9ba31 New implementation for the Python hash and compare methods.
* Change: In Hurricane::Isobar/PyHurricane.h, make the hash function use
    the DBo id whenever possible instead of the object pointer, fall back
    to it for standalone objects (Box like one). The DirectHashMethod()
    macro generate a C style function (linkage) which call a template
    function "getPyHash<>()" that uses a SFINAE mechanism to select
    the right variant.
      Create two comparison macros DirectCmpByPtrMethod() and
    DirectCmpByValueMethod() to customize the comparison for objects that
    have C++ operator==(). So now two boxes with the same contents will
    be seen equal by Python. For DBo objects we keep the previous
    comparison by C++ pointer.
2019-11-14 23:56:01 +01:00
Jean-Paul Chaput f130417232 Various bug fixes for Analog P&R. OK for GM/Chamla & OTA/Miller.
* Change: In CRL::RoutingLayerGauge::getHorizontalGauge(), when selecting
    the default gauge, try, if possible to avoid the PinOnly one.
      Same goes for the vertical one.
* Bug: In Katana::TrackCost CTOR, symmetric track axis position was wrong,
    was using the reference instead of the symmetric.
* Bug: In BoraEngine::updatePlacement(), set up the Dijkstra search halo
    to one pitch so it can use immediately neighboring channels.
* New: In BoraEngine, added python startup hook like in Katana. Mainly
    to setup debug nets.
2019-11-13 23:31:51 +01:00
Jean-Paul Chaput 1e4b8b4647 Added support for extra resistor rules in Hurricane::Technology.
* New: In BasicLayer::Material, added "info" kind of material for layers
    that are only informationals (i.e. not real GDS one). Created to
    store geometric combination of layers, this is a temporary solution.
      Have to define a clearer semantic for that.
* New: In CRL/helpers/AnalogTechno.py, new "Count" type for count numbers
    that must not go through DbU::Unit converter. They are plain integers,
    but stored in DbU::Unit (keeping track of that semantic is left to
    the user).
2019-11-13 16:09:38 +01:00
Jean-Paul Chaput 88235dc3a4 Added Resistor support. Completed Capacitor & Resistor support in Bora.
* New: In Analog, added Analog::ResitorFamily & Analog::Resistor classes.
* New: In Analog, added inspector support for all Parameter classes.
* New: In Analog, new FloatParameter class (for resistor value).
* New: In CRL/etc/scn6m_deep_09/devices.py, added resistor device.
* New: In Oroshi, support for Resistors, stub for ResistorSnake generator.
* New: In Bora::DNodeSets, added support for Resistor devices.
* Change: In Bora::DSlicingNode, rename setNFing()/getNFing() into
    setBoxSetIndex()/getBoxSetIndex() for semantic coherency.
* New: In Karakaze/python/AnalogDesign.py, added support for Resistor.
    Change in addDevice(), the span which was only meaningful for
    transistor devices is replaced by a parameter argument.
      The parameter argument has to be consistent with the device type.
2019-11-12 02:21:03 +01:00
Jean-Paul Chaput 9d86282b8f In Cyclop CMakeLists, cleanup the switch Qt4/Qt5. 2019-11-10 12:28:50 +01:00
Jean-Paul Chaput a8a904180d In AllianceFramework::createCell(), handle non-existent library. 2019-11-08 00:18:23 +01:00
Jean-Paul Chaput 8035b31f27 First stage in analog capacitor integration
* Bug: In Technology::getPhysicalRule(), if the named layerdo not exists,
    throw an exception instead of silently putting a NULL pointer inside
    a rule.
* New: In Hurricane/Analog, new parameters classes for capacitor devices:
    - Analog::Matrix, a matrix of null or positives integers to encode
      capacitor matrix matching.
    - Analog::Capacities, a list of float values for all component of a
      multi-capacitor.
* New: In Hurricane::Script, add a "getFileName()" method to get the full
    path name of the Python module.
* Change: In Analog::LayoutGenerator, completly remove the logger utility
    as it is no longer used. Simply print error messages instead.
* Change: In Analog::MetaCapacitor, rename top & bottom plate 'T' & 'B'.
    Accessors renamed in "getTopPlate()" & "getBottomPlate()".
* New: In Analog::MultiCapacitor, complete rewrite. Makes use of the
    new parameters "capacities" and "matrix". Dynamically generates it's
    terminals as we do not know beforehand how many capacitors could be
    put in it.
* Bug: In isobar/PyHurricane.h, in Type object definition, do not prepend
    a "Py" to class name (so the keep the C++ name).
* Change: In CRL/etc/scn6m_deep_09/devices.py, add entry for the new
    capacitor generator.
* New: In oroshi/python/ParamsMatrix, add a "family" entry in the [0,0]
    element to distinguish between transistor, capacitor and resistor.
    (this is the matrix of values returned to the LayoutGenerator after
     device generation).
      Now have one "setGlobalParams()" function per family.
* New: In oroshi/python/Rules.py, added DTR rules needed by capacitors.
    Catch exceptions if something wrong append when we extract the rules
    from the technology.
* New: In Bora, the devices are no longer *only* transistors, so the
    possibles configurations are no longer defined only by a number of
    fingers. We must be able to support any kind of range of configuration.
      So the explicit range of number of fingers is replaced by a base
    class ParameterRange, and it's derived classes:
      - Bora::StepParameterRange, to encode the possible number of fingers
        of a transistor (the former only possibility).
      - Bora::MatrixParameterRange, to encode all the possible matching
        scheme for a capacitor. As there is no way to compress it, this
	is a vector of Matrix (from Analog).
* Change: In Bora::DSlicingNode::_place(), the ParameterRange has to be set
    on the right configuration (through the index) before being called.
      The generation parameters are taken from the active item in the
    ParameterRange.
* Change: In Bora::NodeSets::create(), iterate over the ParameterRange
    to build all the configuration. Adjustement to the routing gauge
    pitchs are moved into the DBoxSet CTOR to save a lot of code.
      Semantic change: the index in the NodeSets is now the index in
    the associated ParameterRange and no longer the number of fingers
    of a transistor.
      Check that the ParameterRange dynamic class is consitent with the
    device family.
* Change: In Bora::DBoxSet, same semantic change as for NodeSets, the
    number of finger become an index in ParameterRange.
      In DBoxSet::create(), now also perform the abutment box adjustement
    to the RoutingGauge, if possible.
* New: In Karakaze/python/AnalogDesign.py, add support for Capacitor
    devices.
2019-11-07 17:05:49 +01:00
Jean-Paul Chaput ef0f6f771a In Python scripts, if PyQt 4 fails to load, try PyQt 5.
* In CRL::Cyclop/CMakeLists.txt, add *again* the MOC files to the list
    of .cpp . Don't know what is happening here with MOC under Qt 5.
* In CRL/python/helpers.io, cleanly fails if neither PyQt 4 nor PyQt 5 is
    found. And tell it directly because this the module tasked to handle
    the exceptions/errors...
* In Cumulus/plugins/AboutWindow.py, try PyQt 4 then PyQt 5.
* In documentation/UsersGuide, now tells explicitely that Qt 4 must be
    used under RedHat 7 and Qt 5 under Debian.
2019-10-30 16:58:43 +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).

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).

Jean-Paul Chaput 5914e16f26 Added management for "phlib" I/O pad external connectors (for cougar/lvx).
* New: In CRL::ApDriver::DumpSegments(), drive as top-level segments the
    RoutingPads using a Pin, and not only using a segment. They are not
    exported as top level Pin but only as Segment as they do belong to
    a deeper level.
* New: In Cumulus/plugins/PadsCorona.Side._placePads(), now manage both
    "pxlib" and "phlib*". Pad library management is still hardcoded, this
    should be made a configuration option someday.
2019-10-05 16:04:12 +02:00
Jean-Paul Chaput 02b30b6681 More terse failure message from the global router.
* Bug: In CRL::cstDriver(), re-activate the management of the VstUseConcat
    flag. Why was he removed in the first place?
* Change: In KatanaEngine::runGlobalRouter(), no longer give the details of
    each overflowed edge and the complete list of impacted nets.
    Only a count.

Jean-Paul Chaput d7931391c0 Adjusted routing pitch for METAL4 to METAL7 for FreePDK45 symbolic. 2019-09-19 23:52:03 +02:00
Jean-Paul Chaput 24dedce09c Added core2chip support for Phenitec80.
This commit degrades the run success rate of ARMv2a to 87% (40 iters).
* New: In CRLcore/etc/.../kite.conf, add configuration parameters:
      katana.termSatReservedlocal
      katana.termSatthreshold
    for the new edge capacity computation system.
* New: In CRLcore/etc/symbolic/phenitec06/, add support for N. Shimizu
    small I/O pads (supplied in phlib80). Tune various parameters of
    Anabatic/Katana to increase routing success.
* Change: In CRLcore/alliance/ap/ApParser, make Pin external components,
    so RoutingPad will be build upon in global routing.
      Do not complain when a I/O pad has a physical instance that did
    not exists in the netlist. Just create it (appeared in phlib80).
      When no netlist instance exists in a pad, the pad Cell is still
    considered as terminal.
* New: In Etesian::BloatCells, new profile named "3metals" better suited
    for two routing metals technologies (i.e. Phenitec).
* New: In Anabatic::RawGCellsUnder, new CTOR which take only source &
    target points instead of a segment. Needed to manage wide segment for
    which the axis to consider is not that of the segment (one axis for
    each track it intersect).
* New: In Anabatic::GCell, add a RoutingPad count attribute, for Edge
    reservation computation.
* New: In AnabaticEngine::computeEdgeCapacities(), instead of decreasing
    all edges of a fixed amount (hTrackReservedLocal), guess the GCell
    cluttering from the number of RoutingPads that it contains.
      For non-saturated GCells, the four edges are decreased by the number
    of RoutingPads. We use the maximum from the two neigboring GCells.
    The hTrackReservedLocal parameter is now used only as a *maximum*
    that the edge reservation can reach.
      If a GCell is saturated (more than 8 RoutingPads, the saturation is
    propagated horizontally to 2 neigboring GCells).
* Change: In AutoContactTerminal::getNativeConstraintBox(), use a more
    flexible gauge name matching for terminal vertical extensions correction.
    Namely, match all "msxlib*" kind of gauges.
* Change: In AutoSegment::setAxis(), add the ability to force the axis
    position, even if it is a non-canonical segment. Maybe needed in the
    initialisation steo, before the first canonisation is performed.
* New: In NetBuilder, added new methods _do_1G_1PinM1() and _do_2G_1PinM1(),
    to manage coronas for Phenitec designs.
      To avoid various side effects from segments being too close from
    the north / east side of the routing area, make those segments fixeds.
* Change: In KatanaEngine::annotateGlobalGraph(), the management of wide
    wires was wrong. The axis to use to find the underlying GCells is the
    one of the track, not of the segment. This was creating bad edge
    capacity computation under the power ring of a block and subsequently
    routing failures.
* New: In Kanata::Manipulator, added method reprocessParallels(), not used
    though, but keep it anyway, might be of use later...
* New: In Kanata::Manipulator, added method avoidBlockage() for terminal
    METAL2 in non-preferred direction, restrict the terminal and turn
    constraint box at the current position of the perpandicular, so it
    doesn't create a deadlock in METAL2.
* Change: In SegmentFsm::conflictSolveByPlaceds(), if we cannot break
    using the whole overlap, try the first atomic overlap.
* New: In SegmentFsm::_slackenStrap(), manage conflict between a non-prefered
    segment and a blockage, this when to call avoidBlockage()...
* New: In Katana::Configuration, management of the new edge computation
    parameters:
      katana.termSatReservedlocal
      katana.termSatthreshold
* New: In Cumulus/plugins/Core2Chip, support for Phenitec I/O pads.
2019-09-17 17:05:54 +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.
2019-08-16 00:40:49 +02:00
Jean-Paul Chaput f92b48174b Correct management of "fused_net" in Alliance parser/drivers.
* Bug: In CRL::ApDriver & CRL::ApParser, when saving a fused net, do not
    use it's name but put a star (*) character to set it anonymous.
      Having all component named was creating problems in cougar and
    subsquently in yagle (bad name for master latch).
      Conversely, in the parser, if the name of the net is "fused_net",
    make it a real fused_net and not an ordinary one.
2019-08-15 01:59:38 +02:00
Jean-Paul Chaput 5877691cde The VST driver can now be setup to use or not concat ('&') in PORT MAP.
* New: In CRL::AllianceFramework::saveCell(), through the view flag we
    can pass an option 'CRL::Catalog::State::VstUseConcat' to tell the
    driver tu use or not the concat '&' in PORT MAP statements.
      It is not completely clean that the flag for controlling the VST
    driver behavior is put in the Catalog states, but it's easier for
    now...
      And, of course, exported at Python level.
2019-08-13 14:46:23 +02:00
Jean-Paul Chaput d670de4125 Added support for 3 metal layers symbolic Phenitec 0.6um.
* New: In CRL/etc/symbolic/phenitec06, configuration for symbolic
    layout targeted for Phenitec 0.6um (do not contains any NDA
    covered informations). Could be used for any 3 metal layers
    techno.
* Bug: In Cumulus/plugins/chip/Configuaration.py, _setStackposition()
    disable stack error when there is no slave component on the stack
    (happens when the stack consists only of one contact).
2019-08-12 15:41:17 +02:00
Jean-Paul Chaput e80fcd8648 Remove VHDL driver extension/property after use.
* In CRL::vstDriver(), remove the Vhdl::EntityExtension right after driving
    the file. This avoid keeping in memory a mostly usnused structure and
    solve the "second write after modification" problem.
2019-08-08 14:12:22 +02:00

Jean-Paul Chaput 1359fe4ba6 Change Net name merge policy in the Blif parser.
* Change: In CRL/BlifParser::Model::mergeAlias(), do not always merge the
    net2 with net1 (RHS with LHS of the ".name" instruction). This may
    result in a name change in the design interface (external net).
      Instead, merge any internal net with the external, so keep the
    external net name. If both are external, keep the one with the lower
    id (which should have been created first).

Jean-Paul Chaput d69327d9a9 Various typos correction (courtesy of G. Gouvine). 2019-07-30 13:13:57 +02:00
Jean-Paul Chaput f528cdea4c Upgrade of Katana detailed router to support Arlet 6502.
* Change: In Hurricane::SharedName, replace the incremental Id by a hash key.
    This is to ensure better deterministic properties. Between use cases,
    additional strings may have to be allocated, shitfing the ids. Even if
    hash can be duplicated, we should be able to ensure that the absolute
    order in map table should be preserved. Supplemental strings are inserted
    in a way that keep the previous order.
* Change: In CRL/etc/symbolic/cmos/kite.conf, add "katabatic.routingGauge"
    default parameter value ("sxlib").
* Change: In CRL/etc/common/technology.conf, define minimal spacing for
    symbolic layers too (added for METAL4 only for now).
* Change: In CRL::Histogram, extend support to dynamically sized histograms.
    Add a text pretty print with table and pseudo-curve.
* Change: In Cumulus/plugins/ClockTreePlugin, create blockage under the
    block corona corners so the global router do not draw wire under them.
    This was creating deadlock for the detailed router.
      When the abutment has to be computed, directly use Etesian to do it
    instead of duplicating the computation in the Python plugin.
* New: In Etesian, as Coloquinte seems reluctant to evenly spread the
    standard cells, we trick it by making them bigger during the placement
    stage. Furthermore, we do not not uniformely increase the size of the
    cells but create a "bloating profile" based on cell size, cell name
    or it's density of terminals. Currently only two profiles are defined,
    "disabled" which does nothing and "nsxlib" targeted on 4 metal layer
    technologies (aka AMS 350nm, c35b4).
* Bug: In Knik::MatrixVertex, load the default routing gauge using the
    configuration parameter "katabatic.routingGauge" as the default one
    may not be the first registered one.
* New: In AnabaticEngine::setupNetDatas(), build a dynamic historgram of
    the nets terminal numbers.
* Bug: In Anabatic::AutoContact::Invalidate(), always invalidate the
    contact cache when topology is invalidated. In case of multiple
    invalidations, if the first did not invalidate the cache, later one
    that may need it where not allowed to do so. The end result was correct
    nonetheless, but it did generate annoying error messages.
* Bug: In Anabatic::AutoContactTurn::updateTopology(), bad computation
    of the contact's depth when delta == 2.
* Bug: In Anabatic::Gcell::getCapacity(), was always returning the west
    edge capacity, even for the westermost GCell, should be the east
    edge in that case.
* New: In Anabatic::AutoSegment, introduce a new measure "distance to
    terminal". This is the minimal number of segments separating the
    current one from the nearest RoutingPad. This replace the previous
    "strong terminal" and "weak terminal" flags.
      This distance is used by Katana to sort the events, we route the
    segments *from* the RoutingPads *outward*. The idea being that if we
    cannot event connect to the RoutingPad, there is no points continuing
    as thoses segments are the more constraineds. This gives an order close
    to the simple ascending metals but with better results.
* New: In Anabatic::AutoSegment, introduce a new flag "Unbreakable", disable
    dogleg making on those segments. mainly intended for local segments
    directly connecteds to RoutingPads (distance == 0).
* New: In Anabatic::AutoSegment, more aggressive reducing of segments.
    Now the only case where a segment cannot be reduced is when it is
    one horizontal branch in a HTee or a vertical on a VTee. Check if,
    when not accounted the source & target VIAs are still connex, if so,
    allow reducing.
* New: In Anabatic::AutoContact, new state flags CntVDogleg & CntHDogleg
    mainly to prevent making doglegs twice on a turn contact. This is to
    limit over-fragmentation. If one dogleg doesn't solve the problem,
    making a second one will make things worse only...
* Bug: In Anabatic::Configuration::selectRpcomponent(), we were choosing
    the component with the *smallest* span instead of the *bigger* one.
* New: In Anabatic::GCell, introduce a new flag "GoStraight" to tell that
    no turn go be made inside those GCells. Mainly used underneath a block
    corona.
* New: In AnabaticEngine::layerAssign(), new GCellRps & RpsInRow to manage
    GCells with too many terminals. Slacken at least one RoutingPad access
    when there is more than 8 RoutingPad in the GCell (slacken or change
    a vertical METAL2 (non-preferred) into a METAL3).
* Change: In Anabatic::NetBuilderHV, allow the use of terminal connection
    in non-preferred direction. That is, vertical METAL2 directly connected
    to the RoutingPad (then a horizontal METAL2). This alllows for short
    dogleg without clutering the METAL3 layer (critical for AMS c35b4).
      Done in NetBuilderHV::doRp_Access(), with a new UseNonPref flag.
      Perform some other tweaking on METAL1 access topologies, to also
    minimize METAL3 use.
* New: In AnabaticEngine::computeNetConstraints(), also compute the
    distance to RoutingPad for segments. Set the Unbreakable flag, based
    on the distance and segment length (local, short global or long global).
      New local function "propagateDistanceFromRp()".
* Change: In AnabaticEngine.h, the sorting class for NetData, SparsityOrder,
    is modificated so net with a degree superior to 10 are sorted first,
    whatever their sparsity. This is to work in tandem with GlobalRouting.
* New: In Katana::TrackSegmentNonPref, introduce a class to manage segment
    in non-preferred routing direction. Mostly intended for small METAL2
    vertical directly connected to RoutingPad. Modifications to manage
    this new variant all through Katana.
* Change: In Katana::GlobalRoute, DigitalDistance honor the GoStraight flag
    of the GCell. Do not make bend inside thoses GCells.
* Change: In KatanaEngine::runGlobalRouter(), high degree nets (>= 10) are
    routed first and whitout the global routing estimation. There should be
    few of them so they wont create saturations and we want them as straight
    as possible. Detour are for long be-points.
      Set the saerch halo to one GCell in the initial routing stage (before
    ripup).
* Bug: In KatanaEngine & NegociateWindow, call _computeCagedconstraints()
    inside NegociateWindow::run(), as segments are inserted into tracks
    only at that point so we cannot make the computation earlier.
* Change: In Katana::Manipulator::repackPerpandiculars(), add a flag to
    select whether to replace the perpandiculars *after* or *before* the
    current segment.
* Change: In Katana::NegociateWindow::NegociateOverlapCost(), when the
    segment is fully enclosed inside a global, the longest overlap cost
    is set to the shortest global hoverhang (before or after).
      When the cost is for a global, set an infinite cost if the overlapping
    segment has a RP distance less or equal to 1 (this is an access segment).
* Bug: In Katana::PowerRailsPlane::Rail::doLayout(), correct computation of
    the segments extension cap.
* New: In Katana::QueryPowerRails::addToPowerRail(), add support for Pad.
* Change: In Katana/PreProcess::protectCagedTerminals(), apply the contraints
    to any turn connected to the first segment of the RoutingPad so the
    perpandicular constraints got propagated to the perpandicular segment...
* Change: In RoutingEvent, cache the "distance to RP" value.
* Change: In RoutingEvent::Key::compare(), sort *first* on distance to
    RoutingPad, then layer depth. If both distance to RoutingPad is null,
    then sort on segment length.
* Change: In RoutingEvent::_processRepair(), try a repack perpandicular with
    perpandiculars first (then with perpandicular last, then give up).
* Change: In SegmentFsm::bindToTrack() and moveToTrack(), set an axis hint
    when creating the insertion event.
* Change: In SegmentFsm::_slackenStrap(), add a step through slacken between
    minimize and maximum slack (wihch directly end up in unimplemented).
* Change: In Session::_addInsertEvent(), add an axis parameter needed when
    the axis of the segment is not the one of the track (case of wide
    segments or non-preferred direction).
* Bug: In Track::_preDestroy(), bad management of the TrackElement reference
    count. Destroy the segment only when reaching zero...
* Bug: In Track::expandFreeIneterval(), forgotten to manage case when there
    is a set of overlaping segments at the "end" of the track, the
    EndIsTrackMax was not set.
* Change: In TrackCost::Compare, increase the cost when an overlaping
    segment is at it's ripup limit. We should try *not* to rip it up if
    we can. Add a dedicated flag "AtRipupLimit".
* Change: In TrackElement, add proxies for isUnbreakable(), new function
    updateTrackSpan().
* New: In TrackFixedSegment CTOR, when a supply wire of METAL2 or above is
    found, make the underlying GCells "GoStraight".
* New: In TrackElement::canDogleg(GCell*), check for already done perpandicular
    dogleg on source/target (reject if so).

Jean-Paul Chaput 8ad910301d In CRLcore, new gauge "msxlib4" for compliance with AMS 350nm (symbolic).
* New: In CRL/etc/symbolic/cmos45/kite.conf, new gauge "msxlib4" for both
    routing and cells. Have only 4 metal layers but with all the same pitches
    and width. Differs from the 45nm compliant where pitches double starting
    from METAL4.
* New: In CRL/etc/symbolic/cmos45/plugins.conf, adjust default parameters for
    the clock tree plugin so they are identical to the one of "cmos" (scaling).
* Change: In CRL/python/helpers/io.py, in catch(), do not set up the script
    path here as it is non-informative.

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 82dc58bf8e Redesign of I/O pads and Corona support to mix real and symbolic.
* Bug: In CRL/etc/symbolic/cmos/plugins.conf, rails dimensions are no
    longer expressed directly in lambda. Must be created using helper.l().
* Change: In CRL::ApParser, slightly more smart management of Pin width.
    Must normalize Pin behavior between Alliance & Hurricane as in
    Alliance they have only one dimension.
* Change: In CRL::LefImport, if a net name end with "!", assume it's a
    global one. Have to check this naming convention.
* Change: In Anabatic::NetBuilderHV::_do_1G_1PinM3() & _do_1G_1PinM2()
    now implemented. Needed for the corona routing support.
* Change: In AnabaticEngine::setupPreRouted(), exclude segments outside
    the abutment box.
* Change: In KatanaEngine::PowerRails, remove the I/O pad support as now
    we route only inside the Corona. So only one vdd/vss/ck are supported.
* New: In cumulus/plugins/ChipPlugin.py, complete rewrite of the chip
    support:
    * Uncouple pad I/O ring whith real cells (foundry) from a symbolic
      core. A new intermediate level "corona" is introduced to handle
      the real/symbolic transition.
    * Ability to explicitly setup position of the pads on the chip side
      in case of uneven distribution.
    * Enable clock tree to be build with 3 metal only (M2 to M4) instead
      of (M2 to M5).
2019-05-10 11:58:05 +02:00
Jean-Paul Chaput 43629a6c1c Tweaking Layer & RoutingGauge management. Allow negative track indexes.
* Bug: In Hurricane python module, forgot to add the Segment type.
* Change: In Isobar/layer.getEnclosure() wrapper check and cast the Layer
    argument into BasicLayer.
* Change: In CRL::RoutingGauge::getLayerGauge(Layer*), getLayerType() and
    getLayerDirection() no longer check layer identity based on layer
    mask instead of just Layer* pointer. To allow a unified call wether
    the layer is real or symbolic.
* Change: In CRL::RoutingLayerGauge::getTrackIndex() and getTrackPositon(),
    no longer consider negative indexes as invalid and reset them to
    zero. The check for out of bound index is now left to Anabatic &
    Katana.
* Change: In CRL/RoutingGauge.getRoutingLayer() and getContactLayer(),
    more detailed error message.
* Change: In CRL/RoutingLayerGauge.getTrackIndex() and getTrackPosition(),
    indexes are now signed long instead of unsigned.
2019-05-10 11:52:42 +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 bbcf14eb5a First step in supporting ISPD18 detailed routing benchmarks.
* Change: In CRL::DefImport, added callback to read the DEF UNITS statement
    and perform a correct length conversion. Previously set to read pseudo
    lambdas in hundredth of microns.
      Added DefParser::getLefCell() to lookup master cells in the LEF
    libraries before looking in the Alliance ones (rooted under "LEF"
    library).
* Change: In CRL::LefParser::_pinPostProcess(), when no segment suitable
    for terminal connexion is found, add all of them. This is a quick hack
    and an a correct policy that match all techno must be implemeneted.
* New: In CRL::pyCRL, add a Python wrapper for DefImport.
* New: In CRL/etc/45/ispd18/ added configuration files for the "real"
    technology used by the ISPD18 45nm design benchmarks.
2019-03-29 11:07:55 +01:00
Jean-Paul Chaput 3a2916b5e6 Improved clock-tree support for variable pitch routing gauges.
* New: In Hurricane::Isobar::PySegment, added wrapper for getOppositeAnchor().
* Bug: CRL::PyRoutingLayerGauge, Python wrapper of getTrackPosition() was
    in fact returning getTrackNumer().
* Bug: In Katana::PowerRailsPlanes::Rail::doLayout(), add the half minimum
    distance to the blockage segments extensions. Was causing too near
    VIAs is cmos45.
* Change: In cumulus/plugins/ClockTree, correctly manage routing gauge when
    the lower pitches (M2/M3) is different from the upper one (M4/M5).
    But we still can only do sxlib compliant gauges because we do not
    handle a switch in preferred routing directions.
2019-03-23 11:05:51 +01:00
Jean-Paul Chaput 5dd235b3cd Adding moc cpps to the link of Cyclop under Qt 5.
* Bug: In CRL::cyclop, on former versions of Qt 5 there was a double
    link of the moc generated modules. This appears to be solved under
    Ubuntu 10.04 LTS, so now we have to add them again explicitly.
2019-03-21 13:27:43 +01:00
Jean-Paul Chaput 94044992ef Pin management implemented for NetBuilderHV.
* Bug: In Katana::Track::expandFreeInterval(), the OutsideElement case was
    not handled correctly, the end index must be increased in that case.
    As a result, this function was returning too short an interval.
      This was affecting the computation of perpandicular free interval
    in DataNegociate::update() for perpandicular fixed but not in a track.
* New: In Anabatic::NetBuilder and NetBuilderVH, now manage GCells with
    one Pin, and up to three globals. Used to put terminals at the
    edge of a block.
* New: In EtesianEngine, now manage placed Pins.
    (done through extractInstanceName())
* Change: In CRL::RoutingGauge::getHorizontalGauge() no longer skip PinOnly
    gauges to find the reference one (same goes for vertical).
2019-03-10 13:25:43 +01:00
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 f107a68938 Reorganisation of menus in a more clear way. 2019-03-05 23:23:14 +01:00
Jean-Paul Chaput 6ae3a902ee Correct H/K parameters for global routing. New cmos45 symbolic.
* Change: In CRL/etc/cmos/kite.conf, setup correct H/K parameters for
    the Katana global router. Value copied from Knik. They give a
    faster solution.
* New: In CRL/etc/cmos45/, new symbolic settings adapted to FreePDK 45nm.
    Courtesy of N. Shimizu. To be used with NSXLIB.
* New In CRL::System, add "coriolis_top" to the set of pathes available
    to the user.
2019-02-26 20:00:28 +01:00
Jean-Paul Chaput 9f69230837 Correct CellWidget & CellPrinter to be really WYSIWYG.
* Change: In Hurricane::CellWidget, new "isPrinter" attribute to know if
    the CellWidget is used as a device for printing.
      New function copyExtensionsGos() to duplicate the ExtensionGo drawing
    callbacks. This is a temporary hack until the ExtensionGo are made static
    to be shared by all CellWidgets.
      In _redraw(), the DrawingQuery flags were not correctly reset between
    different stage of the drawing. This was resulting of uneeded walkthough
    of the slicing tree, along with incorrect display of some of the layers
    (i.e. rubbers where diplayeds when ExtensionGos where active).
* Change: In GraphicKatanaEngine, fine tune the display of GCells for printing
    CellWidget.
* Change: In Hurricane::CellPrinter, copy all the settings from the palette
    of the reference (graphic) CellWidget into the printer CellWidget.
    Also copy the ExtensionGos callbacks so we can print them. Use the
    new CellWidget attribute "isPrinter" for the callbacks to be able
    to adapt to Printer settings.
* Change: In Hurricane::Time::getStringTime(), only print two decimals
    for time durations.
2019-02-20 18:24:43 +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.
2018-10-01 16:52:17 +02:00
Jean-Paul Chaput b53511ea83 Minor adjustements for analog device checker (test of AMS c35b4).
* Change: In CRL::GdsStream, no longer export empty Cells as structures,
    to avoid empty cells in Cadence. To prevent meta-transistors to be
    exported as real physical objects.
      Also put a hard-coded test to prevent exporting "control_r" model
    which is made of AMS standard cells for "amsOTA".
* Change: In CRL/PyRoutingGauge, export the isHV() and isVH() methods so
    the Stack can access it.
* Change: In Hurricane/PyCellViewer, export the removeHistory() method.
    When a Cell is deleted, it must be also removed from the editor
    history. This should be take care of automatically, but for now
    we make it manually through scripts.
* Bug: In Anabatic::NetBuilder::doRp_accessAnalog(), the gauge offset
    was not taken into account when creating initial Contact on
    RoutingPad. The program self corrected afterwards, but with the
    display of a disgraceful message.
* Change: In Anabatic::Configuration and Session, export the gauge offsets.

Jean-Paul Chaput 116d927d1e Correct comutation of metricsBdu in GDS driver (courtesy of M. Koefferlein). 2018-07-17 13:36:17 +02:00
Jean-Paul Chaput d99d797a40 Debugged the GDSII driver. Now working with Cadence.
* Bug: In CRL::GdsDriver::GdsStream two bugs :
    1. The tm fields are int but must be casted into uint16_t in BGNLIB
       and BGNSTR.
    2. The mandatory LIBNAME record was missing.
    3. We also force, for now the dbu to be 1000 and the UU to be 1um.
2018-07-16 19:43:44 +02:00
Jean-Paul Chaput 55a29488c9 Correct handling of lambdas & microns in configuration files.
* Bug: In CRL/etc/NODE/VENDOR/Technology.conf, the database must be configured
    as early has possible so the functions ensuring length conversions can
    work correctly (l(v), u(v)). So we can no longer rely on a table to be
    read after the execution of the file. We perform a direct call to the
    helpers.Technology.initTechno() function. And it must be made first
    thing.
      In all tables taking dimensions, we must use one of the converter
    function helpers.l(v), helpers.u(v) or helpers.n(v) so the the value v
    get converted in lambda, microns or nanometer (resp.). Make the
    modifications in all technology.conf and kite.conf files.
* Change: In CRL/coriolisInit.py, remove the technoConfig variable that has
    been replaced by a direct call to helpers.Technology.initTechno().
* Change: In CRL/helpers.Alliance.loadRoutingGaugesTable(), no longer try to
    convert coordinates, they must already be in DbU.
* Change: In CRL/helpers.__init__.py, remove lambdaMode() and micronsMode()
    they could not be made to work as expected. Create l(), u(), n() as
    replacement.
2018-07-16 11:32:40 +02:00
Jean-Paul Chaput 094cb8a132 Improved handling of short nets (fully included in one GCell).
The short net mode degrade the routing in some cases. This will be
fixed in a next batch of commits.

* New: In Hurricane::NetRoutingProperty, added "ShortNet" flag for Nets
    that are completly inside *one* GCell.
* Bug: In CRL::BlifParser::Model::staticInit(), when looking for the
    output of zero and one cell, also skip the blockage net (as well as
    automatic and supplies).
* New: In Anabatic::AutoSegment, added "ShortNet" flag to know if the
    segment is part of a short net (fully included in *one* GCell).
      Also add accessor/mutators for the _analogMode flag (was it ever
    used before?).
* New: In Anabatic::NetBuilder::singleGCell(), if a RoutingPad is
    vertically small, add a vertical segment to give it some slack.
* New: In Anabatic::Dijkstra::_materialize(), detect "short net" as
    they have only one GCell in their source list...
* Bug: In AnabaticEngine::_loadGrbyNet(), reset the AutoSegment
    "short net" and "analog mode" creation flags between two different
    nets.
* New: In Katana::Configuration, added dedicated ripup for short net
    segmnts.
* New: In Katana: partially implemented support for "short dogleg", that
    is dogleg that are always kept in same metal because they connect
    neighboring perpandicular tracks. Not finished neither activated
    yet.
* New: In Katana::TreckElement and derived, export the the *short net*
    support from AutoSegment.
* Bug: In Katana::RoutingEvent::_processRepair(), when a segment is
    successfully inserted, re-process any perpandicular that is in
    repair state, as it may have a new chance to be placed.
* New: In Katana::SegmentFsm::slackenTopology(), always reject short nets.
* Bug: In Katana::Track::check(), correctly handle wide segments instead
    of issuing false check messages.
2018-07-16 11:16:51 +02:00
Jean-Paul Chaput 6b29ad0078 In AllianceFramework, no longer try to load ".vhdl" files in ".vst".
* Change: In CRL::ParserMap, no longer recognize the file extensions
    ".vhdl" and ".vhd" which are true VHDL and cannot be parsed by the
    "vst" (Alliance structural subset VHDL) parser.
       This should solve annoying problems for the Makefiles when there
    is both the full VHDL file ".vhdl" and the synthesized one ".vst"
    (note that this problem do not arise when using Yosys/Blif).
2018-06-11 16:49:40 +02:00
Jean-Paul Chaput ea9a1f3710 CRL::Blif parser now able to load both non-Alliance & Alliance design.
* Change: In CRL::Blif, we now can add a list of Hurricane library for
    the parser to look for standart cells. If the library list is *empty*
    we look use the Alliance mechanism, if not, we look *only* in this
    library list. This behavior is implemented in Subckt::createModel(). I
      To add a library, use CRL::Blif::add(Library*).
      This allow to manage symbolic or real mode loading, it may need
    some rework to clarify the interface.

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 4f089ffdea Polygon internal normalization. Sub-polygons for GDSII driver.
* Change: In Hurricane::Polygon, store the points so they are always
    ordered in the counter-clockwise (trigonometric) direction. This
    simplicificate internal computations.
* New: In Hurricane::Polygon, added getSubPolygons() methods, that
    split horizontally the polygon in sub-polygons of about 1000
    vertexes. This is mainly to be used by the GDSII driver to abide
    to the XY 4000 points limitation.
* New: In Hurricane::Isobar, export support for Point collections so
    the various contour Polygon methods can be created in the Python
    interface.
* New: In CRL::GdsDriver, split the Polygons into set of sub-polygons
    of less than 1000 vertexes. Use the getSubPolygons() method.
* Change: In stratus1.dpgen_RF2, makes more explicit error messages
    about placement by displaying the faulty vs. expected coordinates.
2018-06-03 11:47:31 +02:00
Jean-Paul Chaput ea16b5a556 Added GDSII parser. Component/Polygon reorganisation.
* New: In CRL, implement a GDSII parser. The complete syntax is supported,
    but only a few subset is really taken into account. It is intended to
    load the layout of standard cells only. The interface of the cell is
    provided through a LEF file and it complete layout through the GDSII.
      The loader work in a Library way. It takes a Hurricane library as
    argument and search in the GDSII library structures with a name
    matching the Cell of the library and complete them.
* Change: In Hurricane::Component, put the Contour methods at Component
    level so we can use them in a generic way in the CellWidget drawing
    primitives.
* New: Hurricane::Rectilinear polygon, for small rectlinear polygons.
    Should be less than 100 vertexes. For bigger ones, use Polygon
    which allows slanted egdes.
* Bug: In CRL, freepdk_45/technology.conf, there seems to be an incoherency
    bettween the GDSII layer numbers as defined in the Cadence FreeePDK45.tf
    file and the one used in the supplied layout of the GDSII cells.
      For now, we align on the GDSII cells to get nice layouts, but it
    has to checked.
2018-05-20 15:47:34 +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 0902b21f23 Added support for huge approximated polygons (for photonics).
* New: Hurricane::Triange as been renamed into Hurricane::Polygon.
    Add support for convex polygons. Polygon are approximateds by
    excess by a manhattan rectilinear polygon (with potentially
    thousands of vertexes). To reduce the memory footprint,
    compaction techniques reducing by at least a factor 4 has been
    implemented. We could go further by only storing the non-repetitive
    part of the edge (defined by the integral fraction dY/dY).
    We will see, if the program slows too much.
      The manhattan approximate is always computed but displayed
    only if the polygon grid step is greated than 4 pixels.
      The level of approximation of the polygons can be controlled
    through the "DbU::_polygonStep" parameter.
* Change: In CRL/coriolisInit.py and CRL/helpers/Technology.py, regroup
    all DbU related parameters into "technoConfig" (i.e. suppress
    "viewerConfig"). Update all the relevant technology.conf configuration
    files.
      Change the loader behavior so that "technoConfig" is read first
    and is now responsible for creating the Technology of the DataBase.
* New: In Hurricane::CellWidget, added support for displaying mahanttanized
    polygons.
* Change: In documenation/scripts/expample/polygons.py, perform (I hope)
    a comprehensive test of the polygons (check all slopes, clockwise and
    conter-clockwise).
* New: In Hurricane::DbU, added template to manage vector<> of DbU.
    Support for the "polygonStep" parameter.
2018-05-04 17:06:41 +02:00
Jean-Paul Chaput 1a338f620c Corrections in the Dijkstra global routing (ripup) mechanism.
* Bug: In Anabatic::Dijkstra, the degree of a vertex (the number of neighbors
    belonging to the same net) was miscalculated. This was leading, in the
    materialize step to some feed-through vertexes not being broken.
    Leading in turn to incomplete transformation of the detailed routing.
      Also in _trackback(), the degree of the first vertex we were backtracking
    from was not incremented.
* Bug: In Anabatic::Dijkstra::materialize(), systematically use
    GCell::breakGoThrough() on both source and target. This is needed when
    we are in the ripup phase as both source and target can be go-through.
      This was also leading to incomplete detailed routing transformation.
* Change: In Anabatic::Edge::ripup(), ripup one third of the segments instead
    of thoses exeeding the global length threshold. This way we are sure to
    desaturate an edge. Needs to be further calibrated.
* Change: In Aanabatic::GCell::breakGoThrough(), no longer return NULL.
    Return existing gcontact if any. Break if it is a go-through and create
    a new gcontact in last resort. Maybe rename this function.
* New: In Anabatic::Configuration, new parameters:
    - anabatic.edgeHScaling, to adjust the length of the horizontal edges
        relative to the vertical ones (this is a ratio).
    - anabatic.globalIterations, set the maximum number of ripup passes
        of the global router.
* New: In CRL/etc/*/kite.conf, added new parameters anabatic.edgeHScaling
    and anabatic.globalIterations.
* New: In Katana::GlobalRoute::DigitalDistance, take into account the new
    edgeHScaling factor. Must be used when the capacity of V-edges differs
    greatly for H-edges (case of AMS 350nm c35b4 for instance).
* Bug: In Katana::GlobalRoute::DigitalDistance, the historic cost is
    computed for an edge length of "1". Must be multiplicated by the
    current edge length to have any measurable effect.
      This bug is finally explaining why the ripup was producing the
    same solutions over and over, the historical cost was negligible!
2018-04-16 12:10:48 +02:00
Jean-Paul Chaput cabbab5140 Correct interval capacity computation around zero in RoutingLayerGauge.
* Bug: In CRL::RoutingLayerGauge::divide() & getTrackNumber(), the number
    of traks crossing an edge was wrongly computed for GCells around the
    zero coordinate, this was due to the change in rouding direction
    around zero. It was starting to show for routing gauges with an offset.
      Note: to simplificate the computation of the capacity of an interval,
    all the track over a Cell are computed from (0,0). The Cell abutment
    box has to be choosen relative to that. The tracks positions are fixed
    all over the Cell (or chip if it is one).
2018-04-13 14:59:40 +02:00
Jean-Paul Chaput 6b4baad8b9 More non-deterministics behavior corrections.
* Bug: In Hurricane::Cell_SubCells collection, order the set<> of Cell
    with Entity::CompareById instead of pointer values.
* Bug: In Hurricane::Component_ConnexComponents::Locator, sort the
    set<> of Components with Entity::CompareById instead of pointers.
* Bug: In Hurricane::Occurrence::operator<(), uses Ids to compare
    both _entity and _sharedPath. Check for NULL pointers.
* Change: In Hurricane::IntrusiveMap, add a debug output in _resize()
    like for IntrusiveSet.
      Note to myself : despite their names, InstrusiveMap are hash
    tables and not map<> in the STL sense.
* Bug: In CRL Core, Vst parser, sort the CellVectorMap on Ids.
* Bug: In CRL::NamingScheme::toVhdl(), sort the set<Cell*> models on Ids.
* Bug: In CRL::toVhdlName(), sort the set<Cell*> models on Ids.
* Bug: In CRL::getInstancesCount(), sort the map<Cell*,size_t>
    gatesByMaster on Ids.
2018-04-08 16:58:55 +02:00
Jean-Paul Chaput 0fa6f8be9b Determinism correction of Hurricane, CRL core & Katana.
* Bug: In Hurricane::Cell::uniquify(), a set<Cell*> sorted on pointers
    was remaining. Now sorted on Entity::Id.
* Bug: In CRL::VhdlEntity, in the driver, the components where driven
    in pointer order (set<> again). Now use ids.
* Bug: In CRL/etc/scn6m_deep_09/technology.conf, the symbolic extentions
    for VIAs and layers were wrong. Have to be multiplied by two.
* Change: In AnabaticEngine, AutoContact and AutoSegment LUTs are now
    sorted on Entity::Id. Should not have had any impact, but better
    safe than sorry.
* Change: In KatanaEngine, Symmetric contraint map<> is now sorted on
    Entity::id. Idem for TrackSegmentLut.
2018-03-25 00:58:22 +01:00
Jean-Paul Chaput 23cb020ed3 Fix in 180/scn6m_deep_09, forgot to setup metal layers mininal spacing.
* Bug: In CRL Core, etc/180/scn6m_deep_09/technology.conf the minimal
    spacing for the metal layers layout were not set, allowing the
    router to place VIAs too close to each others. This was generating
    either DRC errors or short-circuits.
2018-03-21 17:32:05 +01:00
Jean-Paul Chaput 8434b01457 Add missing 'anabatic.routingGauge' parameter for scn6m_deep. 2018-03-19 14:16:05 +01:00
Jean-Paul Chaput 3a6760f52a Bad guessing of the output of zero_x0 & one_x0 in BlifParser.
* Bug: In CRL::BlifParser::Model::staticInit(), when looking for the
    output of the Cell, discard power supplies *and* automatic Nets.
2018-03-19 12:55:22 +01:00
Jean-Paul Chaput dd4a01fe70 Validating channel routing mode (two metals) on SNX.
* New: In Hurricane::Entity, add an id counter limit and a memory size
    limit. The two limits are checked only when a new Entity object is
    created. This should help avoiding massive memory links.
* New: In CRL Core, add a "crlcore.groundName" and a "crlcore.powerName"
    parameter to specify the name of the ground/power signals to be
    created if they are missing in a Cell. For Alliance libraries it
    would be "vss" & "vdd" (default values), but for real technologies,
    it is often "gnd!" & "vdd!".
      The Blif parser is modificated to make use of it.
* Bug: In AnabaticEngine::unify(), set the resulting unified segment in
    the  center of the GCells common side. Gcells under a segment are
    found by using the edge that cover the segment axis. When we have
    a "bend" GCell stack and the axis is wrong, they could be ommited.
      This was causing deleted segments to be not removed from some
    Edges, then core dump.
* Change: In Anabatic::AutoSegment::create(), smarter choosing of the
    reference contact, select the fixed or terminal one instead of
    always the source one.
* New: In Anabatic::Edge::isEnding(), new function to check if a
    segment going through an Edge is starting/ending in either source
    or target GCell of the edge (active only when running in channel
    mode).
* New: In Anabatic::Edge::add(), a segment takes part in the occupancy
    only if it is not ending in either source or target (channel mode
    only). The occupancy due to terminal is pre-computed in Katana.
* New: In Anabatic::Edge::ripup(), in channel mode, never ripup a
    segment which is ending in either source or target (we *have* to
    access this edge to connect to the terminal).
* Bug: In Anabatic::GCell::hcut() and vcut(), force the update of
    the Edge which is on the side that will get splitted by the cut.
    It's capacity will be reduced to it must be updated.
* Change: In Anabatic::GCell::updateGContacts() add a flag to conditionnally
    update horizontals or verticals only. We may require only a partial
    update when resizing the GCell in only one direction.
      This, again, related to the fact that we compute the GCells under
    a segment thanks to it's axis position, so we need to be very careful
    when modificating axis.
* Change: In Katana::Block::resizeChannels(), only update GContact vertical
    position. Do not disturb X positions of segments.
* Bug: In Katana::GlobalRoute::DigitalDistance, in channel mode, some
    Edges can have a zero capacity, but still be reachable if the net has
    a terminal in either source or target. Look for this case and return
    a distance of zero instead of "unreachable". This was causing the
    global routing not to complete in channel mode.
      For computing the edge distance, makes the vertical edges much more
    long (10 times) than the horizontal ones as the vertical capacity is
    very limited. Hard coded for now, should make it a parameter in the
    future.
* Change: In KatanaEngine::annotateGlobalGraph(), decrease the capacity
    of edges with reserveCapacity for each terminal inside a GCell.
    Both north and south edges are decreased as we a terminal will
    block both north and south edges.
      As a counterpart, the Edge capacity is not decreased when the
    global router connect to a terminal.
* Change: In Katana::RoutingEvent::revalidate(), when in repair stage,
    do not expand the slack for horizontal segments in channel mode.
    So they may not overlap the standard cell row.
* Bug: In Stratus documentation, do not use the french option in babel,
    the documentation is in english!
* New: In Documentation, added Hurricane/Python tutorial, part for drawing
    layout.
2018-03-16 16:20:04 +01:00
Jean-Paul Chaput 59917680cb In BlifParser, revert gnd! and vdd! to vss and vdd. 2018-03-08 15:53:02 +01:00
Jean-Paul Chaput 793dbb26b2 Capacity managment by layer in Edges & GCells (plus fixes).
* New: In Anabatic::EdgeCapacity, dedicated object to manage the capacities
    of an edge by layer. This needed now because with real technologies
    layers capacities differs (unlike with symbolic technologies).
      This object is separated to be shared between Edges with identical
    characteristics (direction+interval). Deletion is automatic and
    done through refcounting. All the already allocateds EdgeCapacity
    are kept into a set in the AnabaticEngine (key is (direction,interval)).
* New: In Anabatic::Edge, capacities are stored in a shared EdgeCapacity
    object. The total capacity can be annotated (i.e. decreased).
      EdgeCapacity attribute is created during the materialize() call.
    The capacities are computed at this time.
      The incCapacity() function is renamed in reserveCapacity().
* New: In Anabatic::AnabaticEngine, added attribute _edgeCapacitiesLut
    to store the shared EdgeCapacity.
      Lookup/Creation of an EdgeCapacity is done through _createCapacity().
* Change: In Anabatic::Constants, rename Flags::IllimitedCapacity into
    Flags::InfiniteCapacity. Add Flags::NullCapacity (both for Edges).
* Change: In Anabatic::GCell, implement a by depth (for layer) getCapacity().
    This modification did expose a bug in the density calculation :
    per depth density where divided by the complete density instead of the
    density's depth. This was leading to greatly underestimated densities.
    Thoses underestimations where preventing Dijkstra and layer assignement
    to manage congestion correctly (in fact, it was acting as if there
    never was congestion).
      Also avoid a divide by zero (thus -NAN showing in densities).
* Change: In Anabatic::GCell, rename setEdgeOccupancy() into the more
    accurate forceEdgesCapacities().
      Note for Eric: only the first Edge on each side has it's capacity
    forced. What if there's more than one Edge ?
2018-02-21 00:16:50 +01:00
Jean-Paul Chaput 592c098ab2 Basic support for FreePDK 45 completed.
* New: In Commons, inspector support for std::pair<T,U>.
* New: In Hurricane::Layer, ContactLayer & ViaLayer, support for non
    square VIAs. The hole (cut) remains square, but the various metal
    extensions can now be different in X and Y. The ::getEnclosure()
    method now takes a flag EnclosureH / EnclosureV.
* New: In Hurricane::DbU, inspector support for:
         std::pair<DbU::Unit,DbU::Unit>
	 std::array<DbU::Unit,3>
     Must be defined here as DbU do not exists yet in Commons.h
* Bug: In Hurricane::Interval::getSize(), when the interval is "full span",
    do not return the difference between min and max, but directly DbU::Max.
    (the previous result was -1 !)
* New: In CRL Core Python/Technology.py, support for non square VIAs in
    the configuration files. Applied to FreePDK 45.
* New: In CRL::RoutingGauge, added a "symbolic" flag to tell if a gauge
    is for symbolic layout or not. Exported to Python.
* New: In Anabatic::AutoHorizontal::updatePosition(), differentiated
    computation for soure or target taking account of the VIA extension
    in the right segment metal (due to non-square VIAs).
* Change: In Anabatic::AutoHorizontal::_makeDogleg(), the dogleg is
    UP for HV gauges and DOWN for VH.
* New: In Anabatic::AutoSegment::_initialize(), create a cache of the
    various extension length for each layer (viaToTop, viaToBottom,
    viaToSame).
      New implementation of getExtensionCap() using the previous cached
    extension table. See updatePositions().
      New static functions to access the extension cache in the header:
    getViaTotopCap() ...
* Change: In Anabatic::AutoSegment, in various update methods, updateOrient()
    must always be called *before* updatePositions() as extensions are
    dependant on source/target.
* New: In Anabatic::AutoSegment::getEndAxes() compute the position of the
    first source and last target position (center/axes) on an *aligned*
    set of segments.
* New: In Anabatic::AutoSegment, add a new state flag SegAxisFixed to
    signal segments that can be put on only one track. Specific case
    to VH gauge for a M1 vertical terminal with a M2 vertical segment.
    The M2 is effectively bound to the M1 axis position.
* Bug: In Anabatic::NetBuilderVH::_do_xG_xM1_xM3(), in case of E/W global
    and only one RoutingPad the connexion to the RoutingPad was duplicated.
    It was valid, but totally stupid.
* Bug: In Anabatic::Session::_canonize(), for an aligned segment set,
    intersect the user constraints from all segments instead of only
    considering the canonical one.
      Issue a warning about too tight constraints only for symbolic
    gauges. It may be correct for the real ones.
* New: In Katata::DataNegociate::update(), more accurate computation
    of the perpandicular free interval. Use segment extension cap
    calculation. Create a special case for fixed axis segments allowing
    them to find alternative free interval, try under source and under
    target as they are likely to be draggable segments.
* Change: In Katana::Manipulator::relax(), use the extension cap value
    to compute the axis of the perpandicular segemnts.
* Change: In Katana::Manipulator::moveUp(), now move up the whole set
    of aligned segments instead of just the canonical one.
* Change: In Katana::NegociateWindow::loadRoutingPads(), more accurate
    TrackMarkers insertions for fixed terminals.
* New: In Katana::RoutingEvent::Key::Compare::operator(), segments with
    fixed axis are processed prior to any others.
* New: In Katana::RoutingEventLoop, store segment pointers instead of
    ids to generate more accurate error messages.
* Change: In Katana::RoutingPlane::create(), perform local track
    assignment only for HV gauges.
* Change: In Katana::SegmentFsm::_slackenLocal(), add a "dragMinimize"
    step in the automaton. Mutliple states transitions can occurs in
    a row if an action fails.
* New: In Katana::Session::_toIntervalAxis(), normalize interval
    bounds so they are on track positions (by shrinking the interval).
* Bug: In Katana::TrackMarker CTOR, the weigh computation was wrong.
2018-02-17 20:27:38 +01:00
Jean-Paul Chaput 7bcf47212b Improved management of AutoContactTerminal for VH gauges (real ones).
* New: In Anabatic & Katana, add the new "drag" feature.
    With VH gauges used by real technologies (M1-H, M2-V, M3-H) a new
    routing configuration that was not efficiently handled did appear.
      While the preferred routing direction for metal1 is officially
    horizontal, due to the way the standard cell must be designed,
    their metal1 terminals are still verticals (or punctuals).
      Thus, when connecting to them, we face the case where the metal1
    terminal (RoutingPad) is vertical *and* the metal2 wire is also
    vertical. With that setup, the position of the AutoContactTerminal
    via12 cannot be deduced, it may range all the way over the
    metal1 RoutingPad. What may define it's position is the metal3 the
    metal2 finally connects to. That, is, when we have one horizontal
    (the metal3) and one vertical (the metal1 RoutingPad).
      The intermediate wire of metal2 can be kept to a minimum size
    by "dragging" the via12 close to the via23 when the metal3 wire is
    moved.
* New: In Anabatic & Katana, problem of closely vertically aligneds
    RoutingPads in metal1 is managed first in PreProcess by restricting
    the span of the connecteds metal3 and in _makeDogleg also by restricting
    the span even more tightly (to the RoutingPad itself).
* New: In Anabatic::AutoContactTerminal, add the "drag" support.
    Automatically check if the connecting segment is in the same
    direction as the RoutingPad, if so, sets the "SegDrag" flag.
      The dragging state can be known with the "::canDrag()" predicate.
* New: In Anabatic::AutoHorizontal, add the "drag" support.
    The drag state can be known with the "::isDrag()" predicate.
      In "::_makeDogleg()", when making a dogleg on a dragable segment
    pass the drag state correctly and restrict the perpandicular span
    of the perpandicular to the RoutingPad (though segment user constraints).
    If we make a dogleg on the metal2 is it likely than we cannot go
    straigth out vertically from the RoutingPad, so the new perpandicular
    *is* restricted to the RoutingPad span.
      Idem for AutoVertical.
* New: In Katana::Manipulator, add method "::dragMinimize()" which find a
    hole where to minimize a draggable segment. We finally did not use it,
    but keep it for potential further use.
* New: In Katana::PreProcess, adds a "protectAlignedaccesses()" local
    function to check for vertically aligned metal1 RoutingPads, in that
    case setup user constraints on the metal3 segments so they cannot
    completly cover the other RoutingPad with metal2.
      We also keep a "metal2protect()" function that create a fixed segment
    to lock/protect a RoutingPad. Not used for now.
* New: In Katana::Session, add a RoutingPad locking event mechanism.
    This allows us to request the creation of a locking (fixed segment)
    over a draggable segment. Not used for now.
      Lock events are processeds before all others as they create new
    TrackElements.
* New: In Katana::Track, "::getNextFree()" and "::getPreviousFree()"
    method to find the nearest free interval in a Track after/before a
    position.
* Bug: In Anabatic::AutoHorizontal::getConstraints(), merge with user
    constraints *only* if it's not an empty interval (as we use min/max
    functions). Idem for AutoVertical.
* Bug: In AutoSegments_OnContacts::Locator::isValid(), the boolean test
    must be inverted. Seems it never worked, but we never used it until
    now...
2018-01-25 11:58:04 +01:00
Jean-Paul Chaput ba3ddafdf5 Adjustements for analog routing.
* Change: In Anabatic::GCell::doGrid(), remove the "3 slice height"
    limit (for small digital analog blocs).
* Bug: In Anabatic::NetBuilder::setStartHook(), perform a check for
    a RoutingPad still on a Plug. Diplay an error instead of crashing.
* Bug: In CRL::RoutingLayerGauge::getTrackIndex(), the upper bound
    of the track interval must be included instead of excluded.
* New: In Hurricane::Cell, add a StayOnPlugs flags for flattenNets().
    To keep the RoutingPad occurrences on Plug instead of selecting
    physical components.
* New: In Isobar::PyNet, add setAutomatic() and isAutomatic() to the
    interface.
* Bug: In Katana::protectRoutingPads(), do not create protections on
    PinOnly layers (mostly metal1).

Jean-Paul Chaput 95aba574a5 Happy New Year 2018 ! Update license years... 2018-01-06 17:55:44 +01:00
Jean-Paul Chaput 3d0431b238 In CRL, update real conf. files. Smarter management of pin in LEF parser.
* Change: In CRL Core, etc/, update the configuration files of real
    technologies. Mostly for FreePDK 45. This work is also done for
    AMS c35b4 (350nm) but in a private (SoC) git repository.
      Added a new parameter 'lefImport.minTerminalwidth' for the
    minimum size (width) of a metal1 terminal in standard cells.
      Corrected bug of the minimum trace level which must be
    initialized to a great value and *not* zero;
* Change: In CRL Core, BlifParser, detect when there is no tie low
    or tie high defined, issue an error (connexion left open) but
    continue.
* New: In CRL::RoutingLayerGauge, new overlad of getTrackPosition()
    with the parameter set of getTrackIndex(). Used to know if a
    terminal is on-grid or not.
* New: In CRL::LefImport, smarter management of metal1 pins. Adds a
    _pinPostProcess() function to select the external components
    among the various shapes. If the gauge is VH, all the pin rectangles
    are translateds into vertical segments (even if the metal1 gauge
    says the tracks are horizontals).
      The _pinPostProcess() function adds as external components of
    a net, only the segments of a sufficent width as given in
    'lefImport.minTerminalWidth' and that are on-grid.
2018-01-06 16:18:33 +01:00
Jean-Paul Chaput 24d8fe5957 Cleaner support for real technologies (Hurricane, CRL Core configuration).
* Change: In Hurricane::Technology, in all the layer connexity methods
    (getLayers(), getMetalAbove(), getCutAbove(), getViaBetween(), ...)
    the "useWorking" parameter is replaced by a more accurate "useSymbolic".
      BEHAVIOR CHANGE: formerly, if a symbolic layer was requested, and
    none was found, NULL was returned. Now, if the symbolic layer is not
    found, we try to return the associated real one (same layer mask,
    but not flagged as symbolic, and usually with a lowercase name).
      All thoses changes have been propagated to Python bindings.
* Change: In Hurricane::BasicLayer and derived classes, rename the
    "isWorking" attribute into "isSymbolic" (to match the technology
    renaming).
* Change: In Hurricane::Cell::flattenNets(), ignore power, ground and
    blockage nets for the flatten.
* Change: In CRL Core, in coriolisInit.py and Technology.py helpers,
    rename the tables describing the technology as follow:
      - symbolicLayersTable --> compositeLayersTable
      - workingLayersTable  --> symbolicLayersTable
      - symbolicRulesTable  --> layersExtensionsTable
    This is to give the table names a more clearer semantic after
    merging real technologies configurations (testbench AMS c35b4).
      In particular, we need to define a composite layer for the
    real VIAs, and not only the symbolic ones. And with correct
    enclosures expressed in real dimensions (microns).

Jean-Paul Chaput 24d5e9f172 The min debug level has to be high (10000) and not zero.
* Bug: In Hurricane the ::tstream class must be initialized with a
    minLevel of 10000 instead of zero, as the minLevel go *towards*
    zero as the debug slice [min:max[ is expanded by DebugSession.
      This default value must be repeated in the CRL::System CTOR
    and in the coriolis2/etc/commons/misc.conf.
* Bug: In Hurricane::IntrusiveSet, uses "tsetw(n)" dedicated cdebug
    stream manipulator instead of the STL one.
2017-12-21 17:29:29 +01:00
Jean-Paul Chaput f87bcf717c Complete the modularization of the detail routing converter.
* New: In Anabatic::NetBuilder, set all the attributes as private and
    create accessors and mutators.
      Finish virtualising all GCell build methods and transfer them
    into the NetBuilderHV class.
      Build methods now return a boolean to tell if the GCell was
    processed or not, to allow cascading in the "big switch".
      Reorganise the "big switch" in separate sections only partially
    cascading.
      Truly fuse the *big switch* for channel routing and over-the-cells.
      Create a new method "_do_globalSegment()" to delagate the
    drawing of global segments between two GCell to the derived classes.

Jean-Paul Chaput 62a433ad3c In CRL Core, added helpers.overload() to modificate Python tuples. 2017-11-29 17:06:24 +01:00
Jean-Paul Chaput e51ff95337 Support for non-square routing pitch. Allow loading of "foreign" cells.
* New: In CRL Core, AllianceFramework::getCell(), adds a new Catalog::State
    flags to request the loading of a "foreign" cell. That is, a Cell which
    is *not* in the Alliance libraries, but in *any* library starting from
    the root library. This is a temporary hack to allow the Blif parser to
    run.
* New: In CRL Core, RoutingGauge::getHorizontalGauge() and
    RoutingGauge::getVerticalGauge() to avoid relying on either metal names
    or depth to know the vertical and horizontal default routing
    informations. They return the metal layers gauges *closests* to the
    substrate which are likely to have the lesser pitch.
* New: In CRL Core, BlifParser, new configuration parameters:
    "etesian.cell.zero" & "etesian.cell.one" to figure out what are the
    tielow and tiehigh cells (instead of having the ones from sxlib
    hardwired).
* New: In Etesian, add support for non-square routing pitchs, that is,
    the lowest vertical and horizontal pitches are not equal. Needs to
    work with two pitches (H & V) instead of one.
      The Configuration associated class now also provides the
    RoutingGauge (not only the CellGauge).
      Use a new Configuration setting "etesian.feedNames" to set up
    the names of the filler cells. This a string of comma separated
    cell names.
* New: In Anabatic, Session::_getNearestGridPoint(), use the new
    non-square grid scheme.

Jean-Paul Chaput 20eadc85f3 Bug: LEF/DEF includes in the wrong place. 2017-11-17 15:32:30 +01:00
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).
2017-11-17 11:48:20 +01:00
Jean-Paul Chaput bc1c7838d1 Reorganisation of technology configuration files.
* Change: In CRL Core, in coriolis2/etc the file an directory structure
    describing the technonolies is modified.
      Before, one technology was split in two: the symbolic part that
    may be shared across multiple real technology and the real technology
    itself. To configure this we needed in ".coriolis2/techno.py" two
    variables:
      * symbolicTechnology.
      * realTechnology.
      After, we duplicate the symbolic technology in each real ones, so
    to configure we only have to refer to one technology with the
    variable:
      * technology.
      Pure sympolic technologies are still availables, associated with
    a dummy real one.
      We provides:
      * 180/scn6m_deep_09  for MOSIS 180nm
      * 45/freepdk_45      for FreePDK 45nm (work in progress).
      * symbolic/cmos      for classical Alliance symbolic.
* Change: In CRL Core python/helpers, SymbolicTechnology.py and
    RealTechnology.py are now grouped under Technology.py.

Jean-Paul Chaput bed79c0156 New DataBase::getCell() and bug in Technology::getNthMetal().
* New: Hurricane::DataBase::getCell() method to search a cell through
    all the libraries of *all* the frameworks, not just Alliance.
    Also exported in Python interface.
* Bug: In Technology::getNthMetal() the function was not returning the
    right metal, there was an offset of one. And when the offset was
    0, no metal was even returned. Same fix goes for getNthCut().
      The fault was in Mask<>::nthbit().
* Change: In Hurricane::CellWidget, the initial window size is too tiny.
    Increase the size from 250 to 500 pixels.
2017-11-17 10:54:19 +01:00
Jean-Paul Chaput 4e8ac63408 In CRL Core Python helpers, new showPythonTrace().

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

Jean-Paul Chaput cafced2bf8 Katana manage wide wires, and they can also be symmetric.
* New: In Anabatic::AutoContact and the derived classes, manages wide
    wires. The contact self dimension itself according to the segments
    it is connected to. Special case for the AutoContactTerminal which
    also read the size of the component it is anchored upon.
      New refresh method "updateSize()" and flag CntInvalidatedWidth.
    to compute the size.
      In AutoContactTerminal, compute the constraint box according to
    the width of the segment.
* New: In Anabatic::AutoSegment, flags are now implemented as "static const"
    attributes of the class. The flags are stored into a uint64_t as
    they are more than 32.
      Added new flag "SegWide" and associated predicates.
* Change: In GCellTopology::_doHChannel() and GCellTopology::_doVChannel(),
    uses the simpler overload of AutoSegment::create() in order to detect
    the wire width automatically.
* New: In Katana::Manipulator, split insertToTrack() and forceToTrack()
    into a one-track method and a segment level method that iterate over
    the track span of the segment.
* New: In Katana::SegmentFsm, for each cost in the table, now allow access
    to a specific track. So the base functions have now two parameters:
    "icost" and "itrack" (has a cost can have multiple tracks in the case
    of wide segments).
* Change: In Katana::TrackElement, remove the index of the element inside
    it's track, as for a wide segment it will not be meaningful for the
    non-base track. This means that we have to use the Track::find()
    method each time instead.
      Remove the wide flag, as it is a duplicate of the one in AutoSegment.
      Added a getTrackCount() method to tell the number of track the
    segment is inserted into. Needed in the Track destroy step to delete
    a segment only when the last track that refers it is destroyed.
      Added getSymmetricAxis() to correct the computation of the symmetric
    base track in case of wide segment as the base track is not centered
    but the the leftmost one.
* Change: In Track::insert() insert wide segments in their whole track span.
* Change: In TrackCost, create an array of costs according to the segment
    track span.
* Change: In TrackSegment::create(), now activate the factory and create
    wide segments.
* Bug: In Katana::AutoSegments_Perpandicular, correct the debug indentation
    problem (ever shifting to the right).

Jean-Paul Chaput e78c3f21ef Added analog type on segment NetRoutingProperty.
* New: In Anabatic_AutoSegments collection, added a Flag to the constructors
    to allow different behavior between digital and analog modes.
      For "Aligneds" and "Perpandiculars" collections, now manage a new
    Flag WithDoglegs to follow aligned globals through local doglegs
    (for analog nets).
      Adjust the log level of collections to 144 (formerly 145).
* New: In Anabatic::AutoSegment, new flag SegAnalog for segments that are
    part of an analog net.
      Note that with this flag, we reach the 32 bits limit...
* Change: In Anabatic::Constants, Flags are now declared as BaseFlags
    objects and *not* uint64_t. This avoids overload resolution problems with
    arithmetical overload of the operators.
      The BaseFlags/Flags types are now completly "isolated" from the
    uint64_t, it has the advantage of showing where unwanted previous implicit
    conversions where occuring.
* Change: In Katana::Constants, Flags values are now of BaseFlags type instead
    of uint64_t.
* Change: In Anabatic::Dijkstra, lots of log cleanup.
* Change: In Anabatic::GCell::getSide(), make the "shrink" parameter visible
    to allow to substract the topmost and rightmost track for axis span
    computation in AutoSegment::computeOptimal(). Used for analog mode.
* Change: In NetRoutingState, added a flag for analog mode. Use uint32_t
    for the flags type.
* New: In Isobar, export the NetRoutingState and NetRoutingExtension objects.
2017-05-20 12:33:12 +02:00
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 db8e51524f Deterministic destruction of Components.
* Change: In Hurrican::Component::_preDestroy(), the cascaded destruction
    of slaves Components and subsequent ring merge and Rubber creation
    was using set<> sorted on pointer values. This was making the order
    of destruction of the slaves components non-deterministic. Now the
    sets are sorted according to their id (see Entity).
* Change: In Hurricane::SharedProperty, the _ownerSet is now a vector<>
    instead of a set<>. This will slow the search process, but hopefully
    this is needed only during construction/destruction of a Property
    so the slow down shouldn't be too much.
      This has also an impact on Hurricane::Relation.

Jean-Paul Chaput b99a362509 Apaired segments building for symmetric routing (step 1).
* Change: In Hurricane::BaseFlags, store flags in uint64_t instead of
    unsigned int because we start to need more than 32 different flags
    in some tools.
* New: In ::getString() & ::getRecord() templates, add support for
    std::array<>.
* Change: In CRL::ToolEngine, add support for timer (time & memory
    measurements) displaced from Katabatic. This way all ToolEngine
    can use this feature. The _postCreate() method display the
    memory just after ToolEngine allocation.
* Change: In Etesian::EtesianEngine, make use of the ToolEngine
    builtin timer (remove the local one). Forgot to call the base
    class _postCreate() and _preDestroy().
* Change: In Anabatic::AnabaticEngine, make use of the ToolEngine
    builtin timer (remove the local one).
* New: In Anabatic, new AutoSegments_Connecteds() collection. This
    Collection allows a deterministic walkthough *all* the AutoSegments
    connected either to source or target of one AutoSegment.
* New: In Anabatic::AutoContactTerminal::isEndPoint() to check if an
    AutoContactTerminal is the *only one* anchored on a RoutingPad,
    thus being a true "end point" and not a kind of feed-through.
* New: In Katana::KatanaEngine, added support for symmetric nets.
    Created new class DataSymmetric to store symmetric information
    of a net (mainly the paired AutoSegments).
      Added KatanaEngine::runSymmetricRouter(), for now only build
    the DataSymmetric informations. More to come...
* Change: In Katana::GraphicKatanaEngine::_runTest(), now perform
    symmetric information building the non-symmetric routing.

    going ashtray.

      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'.

* Bug: In Hurricane::DbU, replace long by DbU::Unit (aka int64_t) in all

* Change: In Hurricane::DbU::getValueString(), rewrite using ostringstream.
* Change: In Hurricane, in PyHurricane.h, PyAny_AsLong<> template to
    convert any kind of Python integer into DbU, making sure we always
    use 64 bits integers (long long for 32 bits and long for 64 bits).
      PyDbU_FromLong<> template to peform the reverse, DbU to Python
    integer in 64 bits (either using PyLong_FromLong() or
    PyLong_FromLongLong()).
* Bug: In Isobar, in PyArg_ParseTuple(), never use the "l" direct
    converter when reading a DbU. Instead read a PyObject then convert
    using PyAny_AsLong<>. This ensure to never do a truncature.

    first found.
* Change: In Hurricane/DbU, uses <int64_t> instead of <long> to always be

    RoutingPlanes have been allocateds before trying to delete them.
2016-11-23 11:29:28 +01:00
Jean-Paul Chaput 47c9961ef3 First intergration of the Analogic router parts.
* New: In Anabatic::AutoSegment, introduce a the kind (associated to a
    flag) "LongLocal". Analog GCells can be very wide, so at least some
    carefuly choosen long local segments must be took into account as
    attractors in the computation of the optimal axis.
* New: In Anabatic::AutoSegment::computeOptimal(), take LongLocal into
    account as attractors.
* Change: In ::GCellTopology constructors compare the layers of the
    RoutingPads using layer masks instead of Layer pointers. Allows to
    find both "METALx" (symbolic) and "metalX" (real).
* Change: In ::GCellTopology::_doHChannel(), _doChannel(), _doStrut()
    and _doDevice(), tag long locals as "LongLocal". This need to be
    reviewed as it as bind done a bit too quickly.
* Change: In Anabatic::AutoSegment, due too a much bigger span of the
    analogic GCells the _optimalMin & _optimalMax bitfields must use
    16 bits instead of 8 (they where overflowed).
* New: In Katana, reorganisation of the initialization procedure to fit
    both digital and analogic cases. Create an analogInit() method.
* Change: In Katana::RoutingEvent, the _tracksNb and _tracksFree bitfields
    where too short for the Analog GCell size, now uses 16 bits instead of
    6.
* Bug: In Katana::GraphicKatanEngine::drawGCell(), skip drawing of a
    GCell if *both* width and height are under 150 pixels.
* New: In Katana::Session, add a new isOpen() method.

* New: In Anabatic::GCell, add a display mode to select between boundary
    display (for analogic) and density display (for numeric).
* Bug: In KatanaEngine::runGlobalRouter(), do not check if an Edge cannot
    be desatured when the vector or overloaded Edges is empty.
    (one less disgraceful warning)
* New: In GraphicKatanaEngine::drawGCell(), support for drawing the GCells
    in density mode. Use the fire scale and the MaxDensity mode.
      Setup the GCell drawing mode in GraphicKatanaEngine::initGCell().
* Change: In GraphicKatanaEngine::drawEdge(), adjust the various thresholds
    for showing the Edge and its label.
* New: In CRL Core, adds "anabatic.gcell.displayMode" to the set of Anabatic
    parameters.
      Adjust the showing threshold for GCells in "display.conf" so when the
    zoom level is low, we still can see the density map.

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.

          http://www.plunk.org/~hatch/goodies/backtracefilt.C
      And small trinket: adjust the size of the window for high DPI screens.

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.

Jean-Paul Chaput 36a982ce47 Merge branch 'devel' into devel_anabatic
Catch up the Lemon removal and cdebug correction.
2016-06-11 21:58:25 +02:00
Jean-Paul Chaput f68ac4d0e6 Argh. cdebug was slowing down the program too much.
* Change: In Hurricane Commons.h, even when cdebug print nothing, it slow
    down the program (three times for Kite!). Create a macro cdebug_log
    which calls cdebug *only* if the debug level is active.
2016-06-11 21:56:12 +02:00
Jean-Paul Chaput 747027f23a Simplification of the Hurricane::Observer mechanism.
* Change: In Hurricane::Observer, simplification of the template so that
    we can use it directly instead of creating a derived class with an
    implementation of Observer::notify(). Now the implemenation is the
    same for all and just calls a notify() method on the owner object.
      Create a StaticObservable for fast access of the observers. This
    is mainly a fixed size table (array<>) with oberservers at known
    indexes. This way we can go from the obervable to the observer
    owner in one indirect access (or so I hope).
* Change: In Hurricane::CellViewer, use the new observers.
* Change: In Hurricane::ControllerWidget, use the new observers.
* Change: In Hurricane::CellWidget, set the winidow initial size to a
   more sensible 500px.
* Change: In CRL::LibraryManager, use the new observers.
* Change: In CRL::LibraryManager, use the new observers.
* Change: In CRL, in display.conf & technology.conf, modification for
    the ST hcmos9gp capacitors.
2016-06-03 17:19:46 +02:00
Jean-Paul Chaput a4655aec8b Anabatic transient commit 2.
* Change: In Hurricane, in CellWidget, enable the drawing of ExtensionGos
    according to the the threshold paramaters (as layers do).
* Change: In CRL Core, provide DrawingStyle for Anabatic::GCell &
    Anabatic::Edge. Use the exact name of the ExtensionGo.
      In kite.conf, add settings for the size of an edge as the optimal
    size may change between analog & digital designs.
* New: In Anabatic:
    - Support for fast position query using a matrix.
    - Computation of the Edge capacity, based on the routing gauge parameters.
    - Graphic display of the edges capacity. Added configuration
      parameters to size the bounding box of an Edge.
* Bug: In Anabatic:
    - GCell::_moveEdges was both too complex (some cases never arise the
      way we divide GCells) and bugged.
2016-05-26 13:56:16 +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.

Jean-Paul Chaput 1c7cbbe6f7 Typo in error message raising an exception. 2016-05-06 17:42:05 +02:00
Jean-Paul Chaput babf23f303 Let the init system guess "stratus1.mapppingName" value.
* Change: In Bootstrap, in coriolisEnv.py no longer sets the environment
    variable STRATUS_MAPPING_NAME (guessed by init).
* Change: In CRL Core, in System CTOR sets the default value for
    "stratus1.mappingName" to "not_set" so the init can known it is not
    set.
      In etc/coriolis2/*/stratus1.conf, do not set "stratus1.mappingName".
      In coriolisInit.py, now guess the value of "stratus1.mappingName"
    if it has not already been set by the user. The complete setting
    process is as follow (decreasing priority):
      1. Setup by the user in his ".coriolis2/setting.py".
      2. A "stratus.xml" file is detected in the current technological
         directory (example: etc/coriolis2/65/cmos065/setting.xml).
      3. Fallback value to "etc/coriolis2/stratus2sxlib.xml".

Jean-Paul Chaput f2c036ac6d Corrections in C-Python interface required by Analagic (CHAMS).
* Change: In Hurricane, in PyHurricane.h, in all DirectSet*() macros,
    suppress the third parameter giving the function name. It is now
    build from stringification of other parameters.
      The various macros calls are also modificated all througout
    Isobar.
      Added PyAny_AsInt() to convert a Python Int or Long into an int.
    Maybe we should manage only long, because the type difference seems
    ambiguous in Python itself.
* Change: In Hurricane, in PyHurricane.h, in DirectGetBoolAttribute()
    deduce the function name to display in messages from the arguments.
      Idem for DirectIsAFromCStringAttribute(), DirectGetIntAttribute(),
    DirectGetUIntAttribute(), DirectGetDoubleAttribute() and
    DirectGetStringAttribute().
* New: In Hurricane, in PyHurricane.h, new macro DirectGetNameAttribute()
    to build accessors for method returning a Name.
* New: In Hurricane, in PyHurricane.h, new macro DirectSetIntAttribute()
    to build modificators taking int arguments.
* Bug: In Hurricane, in PyHurricane.h, in macro DirectSetBoolAttribute(),
    the check for a boolean PyObject was wrong, leading the macro to
    systematically emit a Python exception.
* Bug: In Hurricane, in PyInstance method table, PyLibrary_create() was
    registered as a NOARGS function, but it *do* have arguments, change
    to VARARGS.

Jean-Paul Chaput 09e5784bc4 Bad active width extension on PTRANS/NTRANS in scmos_deep_018.
* Bug: In CRL Core, in scmos_deep_018/technology.conf, the extension
    width in PTRANS/NTRANS active layer was too big. 4.0l instead of
    3.0l. This was preventing seeing gaps in the active layer by cgt.
    They did show up under Graal though...
2016-04-14 21:35:08 +02:00
Jean-Paul Chaput b46c06042b Added Python support for AllianceLibrary in CRL Core.
* New: In CRL Core, added support for AllianceLibrary.
2016-04-13 18:26:08 +02:00
Jean-Paul Chaput 2a40fa7d92 New "obstacleDw" for Kite.
* New: In CRL Core, in RoutingLayerGauge, adds a new parameter "obstacleDw".
    It represents the distance to add from the *edge* of a blockage segment
    to the next *axis* of a routing track. This was previously computed as
    the pitch minus the mimimum half wire width. This works if the pitch
    is *equal* to the wire width plus the minimal distance (edge to edge).
    But if the wire width is less, than it leads to too great a distance
    around obstacles, making them bigger than they are. And potentially
    blocking everything. To summarize:
         before:  obstacleDw = pitch - wireWidth/2  (deduced)
         after:   obstacleDw = explicitly setup, usually:
                               pitch - max(wireWidth)/2
      Modify the Alliance configuration helper and the various kite.conf
    file accordingly.
* New: In Kite, in BuildPowerRails, make use of "obstacleDw" to compute
    the footprint of a blockage.
2016-04-13 18:21:09 +02:00
Jean-Paul Chaput a4e46444e2 Various problems in the BLIF parser.
* In CRL Core, in BlifParser, when an input terminal of an instance is
    either connected to power or ground, insert a zero_x0 or one_x0
    Cell to avoid direct connection to the supply (the router is not
    able to do it). The names and terminals of the intermediate cells
    are hard-wired for now (to SxLib).
      When merging Nets, always merge internal nets into external ones
    as the other way around is not always legal.
2016-04-04 17:54:09 +02:00
Jean-Paul Chaput d641f236a3 Suppress warnings when flatening a Cell twice.
* In Hurricane, in Cell::flattenedNets(), if the cell has already been
    flattened, do not issue warnings about duplictated flattened nets.
* In Hurricane, in Net, allow Net::setName() to switch the main name
    for an alias without complaining about an already used name.
* In Cumulus, in RSavePlugin.py, when "views" is supplied in keywords
    (kw) arguments, override the default instead of merging with it.
    This is to allow scripts to save exactly what views they want.
2016-04-02 14:47:10 +02:00
Jean-Paul Chaput 6ad644fac2 New relation for slaved ABs. Do *not* delete blockage nets.
* Change: In Hurricane, in DataBase::CellDepths() the recursion stop
    criterion must be Cell::isLeaf() and not Cell::isTerminal() as
    the second one can be used to hide some levels of hierarchy,
    and we want all of them in a blob.
* New: In Hurricane, in Cell, create a new Slaveds relation to keep
    track of all the Cells with a slaved abutment box. This work is
    incomplete as we do not manage the behavior in case of merge or
    Cell destruction or slaving Cells with aready slaveds ones.
      Modify Cell::setAbutmentBox() to work in both autonomous and
    slaved mode.
* New: In Hurricane, in Net, add a new type of Net: BLOCKAGE this
    avoid us to be dependant on the framework pattern recognition.
    (change propagated to the Python support)
* New: In CRL Core, in the various drivers, recognize blockage nets
    as such and set their type accordingly.
* Change: In CRL, in Toolbox::deleteEmptyNets(), preserve blockage
    Nets. This was the cause of crashs in Kite::BuildPowerRails() as
    we where trying to use a deleted blockage net...
* Bug: In Hurricane, in NetAlias, do not write NetAlias as a name
    but as a type. They were not read back and moreover staying in
    the JSON parser stack.
2016-03-30 17:47:00 +02:00
Jean-Paul Chaput a78882fd5b Clocks in BLIF parser. In RSavePlugin, flags to select views to save.
* Bug: In CRL Core, in BlifParser, recognize clocks (Alliance patterns).
* Change: In Cumulus, in RSavePlugin, "kw" manage a new "views" to
    specify which views must be saved. Physical by default, but sometimes
    we need logical as well. If the design contains uniquified cells,
    save the logical view.
      In ClockTree, abort the clock tree building if the design has no
    top level clock.
* Change: In Katabatic, in GCellTopology, adds 2G_5M1 configuration.
* Bug: Kite, in BuildPowerRails, if we are not in a chip the nets
   composing the H-Tree must be protecteds be blockages.
2016-03-26 11:59:32 +01:00
Jean-Paul Chaput 1ef4bc122f Forgot to catch Bug exception. GCell manage 5 terminals of a Net.
* Bug: In Hurricane, in HApplication, ExceptionWidget ans PyHurricane.h,
    forgot to catch the Hurricane::Bug exception which was leading to
    terminate() without explanations.
* Change: In Katabatic, In GCellTopology, now support one GCell with
    five metal1 terminal of the same net. This unlikely configuration
    did appear in the SNX for the first time...
2016-03-17 16:54:53 +01:00
Jean-Paul Chaput b9da9531a7 The VHDL driver must not rename Cell/Instance/Net names.
* Change: In CRL Core, the Alliance VHDL (vst) driver was renaming the
    names of Cells, Instances and Nets into their VHDL conterparts.
    But if we still work on the Cell after saving it, the Net renaming
    will cause touble, especially when there are DeepNets. The name
    of the DeepNet is generated from the Occurrence name with the dot
    separator which is *not* a VHDL valid character for name, thus
    after that the DeepNet name has changed it cannot be reassociated
    with the Occurrence path. This was causing double-flattening issues.

Jean-Paul Chaput 12ac23713e Duplicate ScalarSignal creation (signal & global) in VhdlEntity.
* Bug: In CRL Core, in VhdlEntity, when a scalar signal is also global,
    two ScalarSignal where created, but only one can be linked as a
    property on a Net. So when the one *not* linked as a property was
    deleted, an infinite loop started (under Cygwin at least).
      The _globals list now contains pointers to signals that are in
    _signals. The _globals elements no longer needs to be deleted.
2016-03-03 18:14:20 +01:00
Jean-Paul Chaput b57c81dda8 Bug in Cell::_preDestroy().
* Bug: In Hurricane, in Cell::_preDestroy(), the classic mistake again:
    do not iterate over a collection while deleting it's elements.
    Now should be safe.
* Change: In CRL Core, set the default display style to "Alliance.Classic [black]"
    (my favorite).
2016-02-23 17:19:42 +01:00
Jean-Paul Chaput 0efe75af00 Implementation of DataBase native save/restore in JSON (step 3).
* Test: post-receive hook on server should send mail [1].
* New: In VLSISAPD, in Parameter, callback have now a tag, which the
    pointer to the caller. This allow for the callback removal when
    the caller is destroyed.
* New: In VLSISAPD, in WidgetDescription, when associated to a parameter,
    the destructor must remove the associated callback function on
    the Parameter.
* New: In Hurricane, added JSON support for Configuration, separated
    from vlsisapd, as the support is not available at this point.
    JSON support for Configuration, Parameter & LayoutDescription.
* Change: In Hurricane, in JsonStack, the stack of JsonObjects has been
    displaced here from HurricaneHandler. This way, all
    JsonObject::toData() can access the JsonOjects in the context
    of the parser.
* New: In Hurricane, in DBo::toJson() added support for Entity by
    reference (ids).
* New: In Hurricane, added JSON support for all Layer sub-class types.
* New: In Hurricane, in Technology, export the Layers, but must be
   sorted by increasing mask value.
* New: In Hurricane, in Entity, added support for Entity by reference (ids).
* New: In Hurricane, in DataBase, added technology full support.
* New: In Hurricane, In JsonNet, move the ring rebuild management from
    JsonStack to JsonNet.
* New: In Hurricane, added JSON support for NetAlias, NetExternalcomponents
    (not cleanly implemented as a Relation).
* New: In Hurricane, new method Cell::fromJson() to load a cell from
    a JSON file.
* New: In Hurricane, In Graphics, make it an observable, for when JSON
    fully reload the graphic state, it must be able to notify other
    objects (namely the Controller).
* New: In Hurricane, in ControllerWidget, observe the Graphics to regenerate
    the palette as needed. New method ControllerTab::graphicsUpdated().
* New: In Hurricane, in RawDrawingStyle added a destructor to release the
    Qt pen/brush. Added JSON support for HSVr, DrawingStyle, DrawingGroup,
    & DisplayStyle.
* New: In Hurricane, in GraphicsWidget, rewrite correctly the readGraphics()
    to erase the previous widgets and re-create the new ones.
* New: In Hurricane, in PaletteWidget, correct re-creation of the layout/widgets
    in case of Graphics change.
* New: In CRL Core, in System, register the parameters callbacks with
    the address of the object, for later deletion.
* New: In CRL Core, in AllianceFramework, make it observable, to notify
    library changes. For the AllianceFramework creation, now allow to
    completly bypass the Python initialization system, when we expect
    to restore it from a full blob. Added methods to sets the default
    RoutingGauge & CellGauge.
* New: In CRL Core, added JSON suppport for CellGauge, RoutingLayerGauge
    & RoutingGauge.
* New: In CRL Core, in LibraryManager, oberver AllianceFramework, to update
    the list of libraries in case of change (for JSON full reload).

Jean-Paul Chaput 5baddeb558 Implementation of DataBase native save/restore in JSON (step 2).
* New: In boostrap, in ccb.py, added support for the "support" project
    which contains external dependencies. Currently contains only
    RapidJSON. Those dependencies must be cloned here manually.
* New: In Hurricane, Initializer class for an ordered static initialization
    across different compilation modules.
* Change: In Hurricane, at DataBase level, no longer save the Cells in
    the libraries, but create and ordered list of Cell. Deepest cells
    (leaf cells) first. To avoid dependency problems.
* New: In Hurricane, JSON support for Property.
* New; In CRL, added JSON support for AllianceFramework, Environement &
    Catalog and their associated properties. Adjustment of the
    AllianceLibrary creation policy.
2016-01-21 00:25:39 +01:00
Jean-Paul Chaput f537a10d45 Implementation of DataBase native save/restore in JSON (step 1).
* New: In Hurricane, added first support for DataBase native import/export
    using JSON.
      We choose RapidJSON, in SAX mode, to manage the JSON format low level
    Read/Write. Thus, it's Git repository http://github.com/miloyip/rapidjson
    must be added under ~/coriolis-2.x/src and manually build and installed
    in the Coriolis installation tree (to be integrated in ccb later).
      Two mode are being supported:
        1. Cell mode: one Cell only is saved. In that mode, Entities
           referred by Occurrences are "outside" the file. They are coded
           through their "signature" (mostly, all the values of their
           attributes). The ids saved in the file cannot be restored
           identically as we cannot predict when and in which context the
           Cell will be reloaded.
        2. Design Blob mode: the whole design hierarchy, down and including
           the standard cells is saved. This way the design is completly
           self contained and Entities ared referred through their ids.
           A design blob can only be loaded immediatly after starting cgt
           as the DataBase *must* be empty. This way we restore the whole
           design hierarchy with *exactly* the same ids.
      Now, Hurricane object should provide a "toJson()" method for driving
    JSON, and be associated with a JsonObject derived class for parsing.
* New: In Hurricane, ability to force the next id that will be used for a
    DBo (used by Design Blob Mode).
* New: In Hurricane, in DataBase, added getCell() and getLibrary() functions
    to allow the hierarchical access of a Cell/Library in native mode
    (i.e. whithout the requirement of AllianceFramework).
* New: In Hurricane, In CellViewer, added menu entry for Save/Load of
    JSON Design Blobs. Added at this level because we consider it as the
    "native" format of Hurricane.
* New: In Unicorn, added support of import/export of JSON Cell.
* Bug: In Hurricane, in Instance, when cloning an Instance or uniquifying
    it's master Cell, we forgot about the Occurrences (through shared pathes).
    When an instance is cloned the Shared pathes still points toward the
    original Instance. And when it's the master Cell that is uniquifyed
    it's the Entities pointed to that remains in the original Cell.
    This is a software design problem. It is difficult to define what
    policy to adopt when uniquifying: basically that means that one
    Occurence is either moved onto the clone or duplicated. Furthermore,
    it is not trivial to known what Occurrence is pointing on the
    uniquifyed/cloned item. Have to think about it a little more.
* Bug: In Etesian, in EtesianEngine, build the flattened nets and their
    RoutingPads *after* uniquifying (through slaving bounding boxes).
    This way we avoid the Occurrences problem described above.
* Bug: In Etesian, in EtesianEngine, invalidate the RoutingPad after
    processing the placement so they are put into the right quadtree.
    This problem is due to the fact that the RoutingPads do not belong
    to the Instance that they refer. And when this instance is moved
    around, she doesn't inform the RoutingPad that is has moved.
    More software architecture design to review...
2016-01-07 13:15:33 +01:00
Jean-Paul Chaput 1adefabb2f Correctly remove VHDL Entity and Bit properties.
* Bug: In CRL Core, in Vst driver, remove VhdlEntity (from Cell) and
    BitProperty/Bit (from Net) with the property remove and not the
    destroy() method. The BitProperty removal was completly forgotten
    leading to the use of removed Signals when doing multiple saves
    (hence core-dump).
* Change: In CRL Core, in Vst driver, never save as Signals the DeepNets
    as they are created by a virtual flatten and do not connect any
    instances at top level. Note that they will exists in the physical
    file if routing layout has been created.
2015-09-06 17:24:04 +02:00
Jean-Paul Chaput ed557d9027 Added support for "same layer" dogleg. Big fix for pad routing.
* Change: In Knik, in Vertex, add a "blocked" flag to signal disabled
    vertexes in the grid (must not be used by the global router).
      Modificate the Graph::getVertex() method so that when a vertex
    is geometrically queried, if is a blocked one, return a non-blocked
    neighbor. This mechanism is introduced to, at last, prevent the
    global router to go *under* the pad in case of a commplete chip.
* New: In Katabatic, in AutoSegment, a new state has been added: "reduced".
    A reduced segment is in the same layer as it's perpandiculars.
    To be reduced, a segments has to be connected on source & target to
    AutoContactTurn, both of the perpandiculars must be of the same layer
    (below or above) and it's length must not exceed one pitch in the
    perpandicular direction.
      To reduce an AutoSegment, call ::reduce() and to revert the state,
    call ::raise(). Two associated predicates are associated:
    ::canReduce() and ::mustRaise().
      Note: No two adjacent segments can be reduced at the same time.
* Bug: In Katabatic, in GCellTopology, add a new method ::doRp_AccessPad()
    to connect to the pads. Create wiring, fixed and non managed by
    Katabatic, to connect the pad connector layer to the lowest routing
    layers (depth 1 & 2). The former implementation was sometimes leading
    to gaps (sheared contact) that *must not* occurs during the building
    stage.
      Remark: This bug did put under the light the fact that the initial
    wiring must be created without gaps. Gaps are closed by making doglegs
    on contacts. But this mechanism could only work when the database if
    fully initialised (the cache is up to date). Otherwise various problems
    arise, in the canonization process for example.
* New: In Katabatic, in AutoContactTerminal::getNativeConstraintBox(),
    when anchored on a RoutingPad, now take account the potential rotation
    of the Path's transformation. Here again, for the chip's pads.
* New: In Kite, support for reduced AutoSegment. TrackSegment associateds
    to reduced AutoSegment are *not* inserted into track to become
    effectively invisibles. When a segment becomes reduced, a TrackEvent
    is generated to remove it. Conversely when it is raised a RoutingEvent
    is created/rescheduled to insert it. All this is mostly managed inside
    the Session::revalidate() method.
* New: In Kite, in KiteEngine::createGlobalGraph(), in case of a chip,
    mark all global routing vertexes (Knik) that are under a pad, as blockeds.
* Bug: In Cumulus, in PadsCorona.Side.getAxis(), inversion between X and
    Y coordinate of the chip size. Did not show until a non-square chip
    was routed (i.e. our MIPS R3000).
* Change: In Stratus1, in st_placement.py add the ClockBuffer class for
    backward compatibility with the MIPS32 bench. Have to review this
    functionnality coming from the deprecated placeAndroute.py.
      In st_instance.py, no longer creates the Plug ring of a Net.
    In my opinion it just clutter the display until the P&R is called.
    Can re-enable later as an option (in Unicorn).
* Change: In Unicorn, in cgt.py, more reliable way of loading then running
    user supplied scripts. Borrowed from alliance-checker-toolkit doChip.py	.

Jean-Paul Chaput ff69a2ef74 Added Hierarchy browser to the Controller.
* New: In Hurricane, added hierarchy browser in the controller.
    The hierarchy is presented as a tree. New MVC, HierarchyInformations,
    HierarchyModel and HierarchyBrowser.
      When using a data model which is not directly connect inside the
    model, we must use the internalPointer field of the QModelIndex.
    But this field is also used by the QSortFilterproxymodel, this
    prevent using it with a Tree model.
      The filter is directly implemented and is specific to each
    Instance entry.
* Change: In CellWidget & CellWidget::State, now store the Cell and
    a Path, this way we can keep track of the hierarchy when browsing.
    The Path is in the State and so propagated back to the Controller.
* Change: In HierarchyCommand, use the Path with setCell().
2015-07-23 00:44:56 +02:00
Jean-Paul Chaput ae6eeb8f56 Merged QuadTrees in overlayed Cells (placed together).
* New: In Hurricane, in Cell & Instance, add the ability to merge the
    QuadTree when *second level* instances of a Cell are placed in
    the same space as the top Cell. This is the case of a deeply
    hierarchical design made of only standard cells that are to
    be placed in a "flat" manner.
      The design is uniquified then the intermediate instances models,
    which should be unique at that point have their QuadTree merged
    through a call to Instance::slaveAbutmentBox(). That method will
    make the model of the instance use the QuadTree of the Cell to
    which the instance belong. The instance model no longer posseses
    a dedicated QuadTree. As a corollary the abutment box of both
    Cell are kept identical and the Instance has it's transformation
    set to (0,0,ID).
      Remark: when we talk about "QuadTree", we mean in fact the
    QuadTree for the instances *and* the SliceMap (Layer+QuadTree).
      Consequence in Query: when going through the resulting
    "flattened" QuadTree we will find objects with an incomplete
    Path du to the fact that we didn't have to explore their
    Instance/Cell level to reach them. The shunted part of the
    Path is stored in the Go master Cell in the _shuntedPath
    attribute. This also affect the displayed depth of hierarchy,
    but not too badly.
* New: In Hurricane, in Cell, new methods:
    - Cell::updatePlacedFlag() : set the placement flags.
    - Cell::isUnique() : one or less instance.
    - Cell::isUniquified() : is the result of an uniquification.
    - Cell::isUniquifyMaster() : is the reference cell of the
    uniquification.
* Change: In Hurricane, in Cell::Uniquify(), uniquify a Cell only
    if it is unplaced. We do not need to duplicate placed Cells
    (see datapathes).
2015-06-26 18:35:11 +02:00
Jean-Paul Chaput fcb4acadad Improvements & bugs corrections in the LEF/DEF importer/exporter.
* Bug: In Hurricane, In NetAlias::removeAlias(), perform the isMaster()
    check on the *current* hook, not the *this* one... Was preventing the
    removal of most aliases.
* New: In CRL Core, in DefExport, perform a virtual flatten before exporting
    a design. Replace the hard-wired "sxlib" gauge by the current default
    one. More secure management of flattened instance and net names (removal
    of all potentially special characters). In net names, correct management
    of vectorized names (do not systematically add "_net" at the end).
      In DefImport, manage the BUSBITS property and revectorize accordingly
    the net names. When loading nets, systematically remove the alias of
    the temporary net "__prebuild__" (a bug in NetAlias was preventing it).
      In LefExport, the right value of MANUFACTURINGGRID in pseudo symbolic
    mode is 0.5 (expressed in lamba). That way all length are even multiples
    of it. Note that there is still the order bug of the 5.7 drivers that
    puts that entry *before* UNITS in the LEF file (bad bad Cadence).
2015-06-18 15:12:01 +02:00
Jean-Paul Chaput d769fafe92 Forgotten files for ST CMOS065 techno (real). 2015-06-12 17:58:30 +02:00
Jean-Paul Chaput e2fcfcb699 Rationalization of Cell's flags. Compilation warnings hunt.
* 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...
2015-06-10 15:49:58 +02:00
Jean-Paul Chaput 701487247d Bug in VHDL portmap. Too strict checking in Kite & Etesian ::setViewer().
* Bug: In CRL Core, in VectorPortMap::VhdlPortMap(), if the connection
    was made to *non-contiguous* bits of an otherwise *contiguous* vector,
    it was using a span instead of the separate bits. Now check that
    bits are contiguous (delta: +1/-1) and the delta do not change of
    sign.
* Change: In Etesian & Kite, the Python interface function ::setViewer()
    was checking that the argument was indeed a CellViewer, but in text
    mode it is None. Now, silently ignore the argument if it cannot be
    converted into CellViewer.
2015-06-08 12:01:32 +02:00
Jean-Paul Chaput 51043df640 Merge "collections" branch from <github> (G. Gouvine).
* New: In Hurricane, in Collection add simple STL iterator support.
    So now the C++11 "for" instruction can be used instead of the
    in-house "forEach".
      Example:
         forEach ( Component*, icomponent, net->getComponents() ) {
           cout << (*icomponent) << endl;
         }
      Become:
         for ( Component icomponent : net->getComponents() ) {
           cout << icomponent << endl;
         }
2015-06-08 11:51:09 +02:00
Jean-Paul Chaput 2906d90b04 Re-activate the LEF/DEF symbolic exporter (for benchmarking).
* 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.
2015-06-07 14:12:00 +02:00
Jean-Paul Chaput 9ac199f11b Change in policy for duplicate libraries.
* Change: In CRL Core, replace duplicated libraries, even when performing
    a Append/Prepend operation. Also correct a bug in library name
    uniquification, event if it's no used. The policy in cas of duplicate
    libraries is not completly clear for me, still.
2015-06-07 11:05:01 +02:00
Jean-Paul Chaput 445104eaf7 Start to support high DPI screen (> 192dpi).
* New: In Hurricane, in Graphics, add a new static method ::isHighDpi()
    which returns true if the DPI is greater than 192. A "normal" screen
    is typically 96dpi, we sets the trigger at twice that value.
      Then in all the widgets with size settings, we uses that method to
    select the more appropriate size.
2015-06-06 18:41:28 +02:00

Jean-Paul Chaput 20ac9080d6 Do not generate IEEE VHDL when driving vst files (silly me). 2015-05-21 14:55:38 +02:00
Jean-Paul Chaput f8a72288aa Better handling of exceptions between C++ & Python. Misc. checks.
* Bug: In Hurricane, in PyHurricane.h the macro HCATCH was not catching
    standard STL exceptions. This was the source of the cryptic message:
        "Fatal Python error: Py_EndInterpreter: thread still has a frame"
    The Python interpreter was interrupted uncleanly bypassing it's own
    exceptions mechanism.
      In PyViewer, the Viewer *do not* inherit from a base class (in the
    Python export).
* New: In Hurricane, in DbU, compute maximum values (in double) for
    grid, lambda & physical (in meter) so now the DbU::toGrid(),
    DbU::toLambda() & DbU::toPhysical() methods can check for out of
    bound values, and throw an exception.
* Change: In Hurricane, ExceptionWidget::catchAllWrapper() now returns
    a boolean, set to <true> if an exception has been catched. Allow
    callers to interrupt themselves if a problem has occured.
* Bug: In Kite & Etesian, in the Python wrapper, send a Python exception
    if catchAllwrapper() did return true, instead of continuing...
* Change: In Kite & Etesian, adds a setViewer() method (exported in Python)
    to use the graphical ExceptionWidget when in graphic mode.
* Bug: In Cumulus, in PadsCorona.py the check for the core vs. chip size
    was not returning False when invalid.
* New: In CRL Core, in Vst driver, add a support IEEE VHDL. Inactive for
    now as I don't see clearly the policy for selecting it or not.
      Remove the code of the old Vst driver.
      In Blif parser, check for non-existent models (incomplete or
    corrupted Blif file). Found by G. Gouvine.
* New: Added extras file for IDE-like support under Emacs.
2015-05-20 14:03:59 +02:00
Jean-Paul Chaput 909f86b4fc Added support for IEEE VHDL in the Vst parser (std_logic).
* New: In CRL Core, in VstParser, support IEEE VHDL, with tokens
    <library> and <use>. If "use IEEE.std_logic_1164.ALL" is present
    the file will be considered to be IEEE compliant.
      To be precise, the parser now support any mix between Alliance
    and IEEE VHDL. So you can have both <std_logic> and <wor_bit>
    in the same file, but it is unclean to do that.
      The two extensions ".vhd" & ".vhdl" are supported.
      The drivers still always creates Alliance VHDL.
2015-05-10 17:16:00 +02:00
Jean-Paul Chaput a2d4f01ca3 New Library Manager Widget. Access with Tools menu or CTRL+M.
* 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.
2015-05-09 17:03:17 +02:00
Gabriel Gouvine dc0485935d Better error messages
* Error messages are more explicit in Ap and Blif parsers
* Warns when not using tie cells
* New layer synonym in ApParser for easier format conversion
* Blif import is now on top
2015-05-02 22:10:42 +02:00
Jean-Paul Chaput 06e5e3060c Complete rewrite of the VHDL (Vst) driver. True handling of vectors.
* Bug: In Hurricane, in NetAlias, bad Record construction of the _next
    field.
* New: In CRL Core, in VstDriver complete replacement of the old Vst
    driver. Needed cleaner architecture to manage correctly files
    importeds through the Blif parser, which are Verilog like.
      It is build as an extension trough property and is not kept
    in sync with the Cell. So it's use should be transient only.
* Change: In CRL Core, in NamingScheme forgot to change '.' (dot)
    forbidden character into '_'.
* Change: In Cumulus, in the RSave plugins, remove the VHDL extensions
    after saving.
2015-05-02 18:39:35 +02:00
Jean-Paul Chaput 479429e12d Support for .gates and .mlatch in Blif. Ap parser beautifying. 2015-04-29 10:41:43 +02:00
Jean-Paul Chaput 770b1fbbbc Support for Uniquification. Rewrite of the Blif parser.
* New: In Hurricane, In NetAlias & Net, add an AliasList collection to
    iterate over all the aliases names (this *not* include the main
    net name).
* New: In Hurricane, In Cell, Instance & Net add support for cloning and
    uniquification (update documentation).
      All Cells that are uniquified from a given model are kept in an
    Uniquify relation. This relation allows to get all the clones and
    generate unique clone names by adding a "_uXX" suffix.
* Bug: In Hurricane, the Cell::_isFlattenLeaf attribute was not initialized
    in the constructor.
* Change: In CRL Core, in AllianceFramework::getCell(), no longer destroy
    a partially loaded Cell in case of parser failure, let the incomplete
    Cell be.
* New: In CRL Core, in ApParser, if all the instances are placed, sets the
    Cell::Placed flag.
* Change: In CRL Core, in BlifParser, complete rewrite of the parser.
    Not so good an idea afterwards...
* New: In Etesian, uniquify the design before placing.
* Change: In Kite, display the list of unrouted wired after all other
    statistics.
2015-04-25 16:52:18 +02:00
Jean-Paul Chaput 4023481da3 Add a state to Cell to know if is placed and/or routed.
* New: In Hurricane, In Cell, add Placed and Routed flags to know the
    state of the Cell.
* Change: In CRL Core, In ApDriver, do not save the RoutingPads as
    external connectors if the design is *not* routed (create
    conflics on reload with the newly generated RoutingPads).
* Change: In Etesian, set the Placed flag on the Cell.
* Change: In Kite, set the Routed flag on the Cell.
* Change: In Cumulus, in RSavePluginAll, save the layout only if it
    has a bounding box.
2015-04-16 16:52:33 +02:00
Jean-Paul Chaput ef9936e87c Support for Net alias names. Blif parser enhancements.
* New: In Hurricane, In Net & Cell, support for Net aliases names.
    Use a structure based on a simple ring of NetAliasHook. The Net
    holds a global map, sorted by names of all the aliases of all Nets.
    Elements NetAliasesHook of the map are slaves of ring whose master
    is an attribute of the Net (it is *not* in the map, as the primary
    name of the Net).
      In case of merge, the aliases of both Nets are merged and the
    name of the merged one become an alias.
      The Cell::getNet() looks in both the Net map and the aliases to
    find a Net by name.
* Bug: In CRL Core, in coriolisInit.py, reoder the loading of the
    configuration files so the real technology is read as early as
    possible to set up the <gridsPerLambda> factor before any lambda
    is actually computed...
* Bug: In CRL Core, in AcmSigda, do not try to fed the file when it
    has failed to be opened. Throw a clean exception instead.
* New: In CRL Core, in Toolbox, add a NamingScheme object to convert
    a design into VHDL compliant names (mainly from Blif/Verilog).
    This is extensible in any case.
* New: In CRL Core, in BlifParser, slightly more informative warning
    messages. Align the loading progress information on the other
    parsers.
      Add a capability to select which component of the design will
    be returned, if there are more than one. Use the "." as separator.
    For exemple you can request "Processor.Alu", which will load
    the "Alu" component from the design in "Processor.blif".
      To be able to save a Blif loaded design, systematically convert
    all the name for VHDL compliance, as it is the format used by
    the Coriolis native files (vst).
      Export the Blif parser to the Python interface.
* New: In Kite, In NegociateWindow, add a counter of the number of
    remaining events. Gives an idea of the ETA...
* New: In Unicorn, in cgt.by, add an option to load a Blif design from
    the command line.
* New: In Cumulus, new RSave plugin to save both netlist & layout.
    Partly redundant with the previous one. Have to better organize
    that later.

Jean-Paul Chaput 2cbb072e6c Merge branch 'github/Blif', fast blif parser. 2015-04-13 18:55:06 +02:00
Jean-Paul Chaput db60fe0aa6 New coriolis launcher. Configuration files cleanup.
* Change: In CRL Core, simplify the loading sequence. The technology,
    both symbolic and real is now loaded directly from coriolisInit.py
    and not through the Alliance loader. This was a leftover from the
    time configuration was in XML. Remove others traces of XML loading.
      Remove SYMB_TECHNO_NAME, REAL_TECHNO_NAME & DISPLAY from the Alliance
    environement, as they was no longer used.
      Note that technology *still* need to be loader *after* Alliance
    framework has been initialized.
      Gauge information is moved from <alliance.conf> to <kite.conf>.
* Bug: In Coloquinte, in optimization_subproblems.cxx static variables
    must not be inlined. Generate a problem when linking in debug mode
    (seems the symbol gets optimised out).
* Bug: In Katabatic, in Grid::getGCell(), when the coordinate is *outside*
    the area, do not try to find a GCell, directly return NULL.
* New: In Unicorn, create a generic command launcher named "coriolis" which
    automatically take cares of all environement setup, then run a command
    by default, it's <cgt>, but it can be anything. For example: <zsh>.

    add their own. See the ImportCell::addImporter() method.
* Bug: In Unicorn, in FindUNICORN.cmake, seems to be unable to detect

    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>,

Jean-Paul Chaput 8566126acc Adding Configuration support to Etesian.
* Change: In Bootstrap & ccb, the coloquinte project is renamed into
    "importeds", it will be the home of all the externally
    devellopped softwares that are needed to build Coriolis.
      Add explicit support for Fedora ("Linux.fc") and uses
    site-packages, as everybody else.
* New: In CRL Core, in etc/, adds the configuration files for Etesian.
* New: In Etesian, activate the Configuration object. Now uses it's
    own configuration variables instead of borrowing those of
    Nimbus & Mauka.
* Change: In Documentation, updated User's Guide to present Etesian
    as the placer, instead of Mauka.
* Change: In Cumulus, slight change in ClokTreePlugin and ChipPlugin
    to match the new Etesian/Python interface.
2015-02-27 18:16:03 +01:00
Jean-Paul Chaput bd3984a313 Correctly manage clock net isolateds from the main clock.
* New: In Bootstrap, in ccb.py, check if cmake is installed and issue
    a warning, if not.
* New: In Hurricane, added Cell::getDeepNet() to search for a deepnet
    given a path and a leaf net. This method is slow and must not be
    used too often. Introduced for Kite::BuildPowerRails().
* Change: In CRL Core, in cmos/alliance.conf, modify the clock name
    pattern to match the sub-clock signals in the datapath operators.
* Bug: In Etesian, do not blindly reset the top cell abutment-box.
    Do it only if it's empty, otherwise keep it.
* Bug: In Kite, in buildPowerRails(), in getRootNet() the management
    of clock nets was incomplete. The case of unrouted clock nets
    that where not connected to the top core clock net, like the
    one in the datapath registers was faulty. They were partly
    recognized as unrouteds and partly as blockage generating a
    routing deadlock: routage impossible due to blockage generated
    from itself...
* New: In Stratus1, add a buildModel() utility function to automate
    the model generation and allow a call by the model name (string).
* Change: In Unicorn, in cgt.py, display the Alliance environement.
2015-02-25 22:22:16 +01:00
Jean-Paul Chaput 6d366a08bc Etesian integration with Chip & ClockTree plugins.
* New: In Hurricane, in DebugSession, add a new method to activate the
    trace inconditionally with a certain level.
* New: In Hurricane, in HyperNet, allow copy construction as there is
    no reason to disallow it and we need it now.
* New: In Hurricane, in Cell::flattenNets(), add a new option to prevent
    the flattening of the clock net(s). For more safety perform the
    DeepNet creation *outside* the Collection loop.
* Bug: In Hurricane, in Cell_HyperNetRootNetOccurrences, skip the
    DeepNets because they are the result of another flattening operation.
* New: In Isobar, in PyBasicLayer, export C++ method getBlockageLayer().
* New: In Isobar, in PyRoutingGauge, export C++ method getLayerPitch(),
    needed by Cumulus plugins.
* New: In Etesian, EtesianEngine::findYSpin() to look for the Y orientation
    if some cells are already placed. Typically the buffers of a clock
    tree.
      Pass the correct orienation to row_compatible_orientation().
      Do not try to add feeds in the ISPD05 benchmarks. For now the
    benchmarks are detected through their names (unreliable).
* Change: In Knik, in KnikEngine::initGlobalRouting(), allow the clock
    to be routed as an ordinary signal when the clock tree is not
    used.
* New: In Kite, in BuildPowerRails, management & detection for the
    pre-routed clock.
      In KiteEngine constructor, early initialization of the blockage
    net to avoid later troubles in BuildPowerRails.
* New: In Cumulus, in ChipPlugin, add support for Etesian plus new
    configuration parameter 'clockTree.placerEngine' to select between
    Mauka and Etesian.
* New: In Cumulus, in BlockCorona, add blockages in the vertical sides
    in the vertical layer to prevent the router to use the vertical
    tracks in under the prower lines (for example, blockage in M3
    with power line M5).
      In Cumulus, in ChipConf add attribute to access the blockage net.
* New: In Cumulus, when the clock tree is disabled, do not generate
    the last rail around the block (the clock rail).
* Bug: In Cumulus, in ChipConf use the clock pad to guess the clock
    signals and *not* the power pad.
      Add more meaningful error messages if a pad global signal is
    not found (implicit connexion by name).
* Bug: In Cumulus, in ClockTree, compute correctly the cells Y spin,
    that is *from the bottom of the cell AB* (not from 'zero').
2015-02-24 13:13:17 +01:00
Jean-Paul Chaput 3b343f08cf Bug in Python proxy deallocation. Update to latest Coloquinte.
* 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.
2015-02-13 23:38:55 +01:00
Jean-Paul Chaput b18219d807 Integration of the latest Coloquinte in Etesian & misc modifs.
* 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).
2015-02-01 23:24:13 +01:00
Jean-Paul Chaput a09e716ce9 More talkative VST parser.
* Change: In CRL Core, in VstParserGrammar.yy display in which mode a file
    is read. Behavioral, structural or model. Model is the step of reading
    the instance's models before truly reading the file.
      In addition, a small optimization, when in behavioral mode, parse
    the file only once.
2014-12-12 18:40:12 +01:00
Jean-Paul Chaput 8eac4b4b6f More robust VST parser.
* Bug: In CRL Core, in VstParserGrammar.yy & VstParserScanner.ll, accurate
    error message positions (file & line numbers).
      When generating error message, we cannot pass char* on variables that
    will be deallocated by the throw. So generate a string that will be
    copied along with the exception. That problems explain numerous
    core-dump when encountering syntaxes errors in the file.
2014-12-11 23:56:59 +01:00
Jean-Paul Chaput 978315c017 Compliance with Clang 3.4 (RHEL7, MacOS).
* New: In Bootstrap, added support for RHEL7 in ccb.py & coriolisEnv.py.
   In coriolisEnv.py, under RHEL6, directly launch a shell under
   devtoolset-2 (do not put it in .bashrc).
* Change: All tools, compliance with Clang 3.2.
   - Call using namespace std *after* at least one include of std has
     been used.
   - In Utilities.h define both const and non-cont overload for operator<<
     of mstream (this was the true cause of the Banner display problem).
   - No longer use defaults arguments in templates, instead create two
     separated overloads.
   - Put template static attributes allocation outside of namespaces
     (this one I'm not sure how to justify).
   - Protect by NDEBUG variables that are only needed in assert().
   - In PyInterval getUnion() & getIntersection() we where silently
     overwriting the "self" object (interval).
   - In Mauka, *do no* overload _postCreate() and add an argument, breaks
     the virtual function mechanism. Rename it into _maukaPostCreate().
     Idem for SubRow().
   - In Katabatic::GCell(), invalidate() overload a Go funtion but is
     used for different purpose at this level. Rename it invalidateCt()
     (invalidate *ConTents*).
   - Miscellaneous small cleanup.
2014-12-09 23:49:46 +01:00
Jean-Paul Chaput 60b0aa5ca7 Rename user's configuration (again), to use '.py' extentions.
* Change: In CRL Core, in coriolisInit.py user configuration files are
    now suffixed ".py" instead of ".conf" (for settings & techno).
2014-10-03 19:11:06 +02:00
Jean-Paul Chaput c244c9ce70 Group all the user configuration file under a ".coriolis/" directory.
* Change: In CRL Core, in coriolisInit.py now read the configuration
    files from a ".coriolis2/" directory. This is to avoid too many
    dot files in the user's directory. Files have also been renamed:
       .coriolis2.conf         ==>  .coriolis2/settings.conf
       .coriolis2_techno.conf  ==>  .coriolis2/techno.conf
* Change: In Kite, in kiteInit.py follow the same policy as CRL Core
    for configuration file.
       .coriolis2.kite.py      ==>  .coriolis2/kite.py
2014-09-27 17:40:35 +02:00
Jean-Paul Chaput 1f9ae36554 Bug fixes for MOSIS SCMOS_DEEP support.
* Change: In Hurricane, the NetRoutingProperty is moved into Hurricane
    from Katabatic. Needed for Knik to be able to access thoses
    informations.
* Change: In Hurricane, in RoutingPad::setOnBestComponent(), now in
    case of identical area, select the component of lowest id.
    This should not be needed if the component ordering was fully
    deterministic as it should be (will investigate later).
      This is to ensure that the choosen component is always the
    same, especially between save/load of a global routing.
* Bug: In Katabatic, in AutoContactHTee::updateTopology(), invalidate
    the segments only if the topology is valid (no NULL in the
    cached segments).
* Bug: In Katabatic, in GCellTopology::construct(), throw an error
    if the topology is bad instead of trying to continue (and core
    dump later... ).
* Bug: In Kite, in BuildPowerRails, distinguish the name of the master
    net in the pad (for vddi, vssi, vdde, vsse, ck, cki & cko) and the
    name of the net in the *chip* netlist. Must use the later to make
    comparison as they may differs.
* Change: In Knik, in save/load solution, exclude nets that are not
    globally routed by Knik. That is which NetRoutingProperty is not
    *Automatic*.
* Bug: In Cumulus, in chip.BlockPower take account of the layer
    width extention to sligthy shrink the connector thus avoiding a
    notch with standart cell in some cases.
* Change: In Cumulus, in chip.ClockTree disable the use of fixed Steiner
    trees for the leaf clocks, as it seems overconstrained for the
    router. First move was to lower them in M2/M3 (instead of M3/M4)
    but that was not sufficent.
* New: In Cumulus, RSavePlugin for recursively saving a physical
    hierarchy.
* New: In documentation, first embryo for RDS file. Should have been
    in Alliance git, but I prefer to keep newest doc in Coriolis.
2014-09-21 16:44:37 +02:00
Jean-Paul Chaput a3963716b1 Correction in plugins to support msxlib compatible pads.
* New: In CRL Core, in helpers & alliance.conf, set and read a "PAD"
    variable to define the pad model name extension ("px" for "sxlib
    and "pxr" for vsxlib, this is provisional).
* New: In CRL Core, in plugin.conf, add parameters to define the name
    of used for power & clock supply. We may remove the extention in
    the future (to be more coherent with the previous modification).
* New: In Cumulus, in chip.Configuration.GaugeConf._rpAccess(), no
    longer place the accessing contact *at the center* of the
    RoutingPad. It works under sxlib because buffers & registers all
    have same size terminals. But this is not true under vsxlib,
    leading to misaligned contacts & wires. Now systematically place
    on the slice midlle track (maybe with one pitch above or below).
      This is still very weak as we do not check if the terminal
    reach were the contact is being put. Has to be strenthened in
    the future.
* New: In Cumulus, in chip.Configuration.ChipConf, read the new
    clock & power pad parameters.
* Change: In Isobar (and all other Python wrappers), uses PyLong instead
    of PyInt for DbU conversions. In PyHurricane argument converter,
    automatically check for both PyLong and then PyInt.
* Change: In Cumulus, in chip.PadsCorona, more accurate error message
    in case of discrepency in global net connections (i.e. no net
    of the same name in instance model and instance model owner.
* Change: In Kite, in BuildPowerRails, when looking up at the pads
    model name to find "pck_" or "pvddeck_", do not compare the
    extension part. But we still use hard-coded stem pad names,
    maybe we shouldn't.
* Bug: In Katabatic, in GCellConfiguration::_do_xG_xM1_xM3(), there
    was a loop in the search of the best N/E initial RoutingPad.
* Bug: In Kite, in KiteEngine::protectRoutingPads(), *do not* protect
    RoutingPads of fixed nets, they are already through the
    BuildPowerRails stage (and it's causing scary overlap warning
    messages).
* Bug: In Cumulus, in ClockTree.HTreeNode.addLeaf(), do not create
    deep-plug when the core is flat (not sub-modules). All the new
    nets are at core level.
* Bug: In Cumulus, in ChipPlugin.PlaceCore.doFloorplan(), ensure
    that the core is aligned on the GCell grid (i.e. the slice
    grid of the overall chip).
* Bug: In Kite, in GCellTopology::_do_xG_xM1_xM3(), infinite loop
    while looking for the bigger N-E RoutingPad. Forgot to decrement
    the index...
2014-09-13 17:45:30 +02:00
Jean-Paul Chaput f85159bdb4 More accurate error message in Python module importation. 2014-09-07 23:16:04 +02:00
Jean-Paul Chaput ae4d938553 Buffer cell configuration in ClockTree. More config parameters in Chip.
* New: In ClockTree plugin, select the name of the buffer cell through
    configuration (parameter: "clockTree.buffer"), and guess the I/O
    name of this buffer automatically.
      Put configuration parameters in plugin.conf and not mauka.conf.
      Bug: strangely triggers a coredump in components collection
    when used with <vsxlib>. Some debug printing still active until
    that is solved.
* New: In Chip plugin, make the size and numbers of the block rails
    configuration parameters (in plugin.conf).
2014-09-02 11:17:47 +02:00
Jean-Paul Chaput 51a3236962 Add management of fixed wires to Kite (for chip ClockTree)
* Change: In Hurricane, in Plug::setNet(), more informative error messages.
* Change: In Hurricane, In Segment, more informative error messages.
* Change: In Hurricane, In DeepNet, accessor for the Net occurrence.
* Bug: In Katabatic, in AutoSegment::create(), error message uses correct
    variables (vertical was using horizontal)...
* Change: In Kite, in BuildPowerRails, already existing wiring in instances
    is copied up as blockage. Uses blockage layer instead of true layer
    (it was a bug).
* Change: In Kite, in BuildPreRouted, consider as manual global routing
    nets with only default wiring (default size wire & contacts).
    Non-default routing is flagged as fixed (with the NetRoutingState
    property).
2014-08-15 19:26:49 +02:00
Jean-Paul Chaput fb4a7457a1 First basic version of ClockTree & Chip plugins.
* New: In Cumulus, first versions of the ClockTree and Chip plugins.
    Clock Tree plugin:
    - It is strongly advised to use have 4 metal routing layers for the
      tree to work. Otherwise, problems can arise with the detailed
      routing (fully obstructed terminals).
    - H-Tree can only be build (for now) for design with a form factor
      between 0.5 an 2.
    - The tree is created at the block top-level and only the leafs are
      trans-hierarchically created on the instances/models. The new
      cell with a clock tree, along with all it's sub-models is created
      with a "_clocked" suffix.
    - Leaf cells are connected through a simple Minimum Steiner Tree.
    - Shorts are avoided by a systematic shift of the wires according
      to their kind. No wire must pre-exist. When used as a sub-module
      of "chip" the wires cannot be moved. When created on a block,
      the wires can be loaded in the detailed router as manual global
      router.
    Chip Plugin:
    - Perform the pad placement and corona creation. Replacement at
      last of the clunky code from Wu Yifei.
    - Relies on a Python configuration file '<design>_chip.py' with
      a "chip" dictionnary.
2014-08-15 19:05:27 +02:00
Jean-Paul Chaput 20f8d004e2 In ACSII/GDS driver, process the complete hierarchy.
* Bug: In CRL Core, in agdsDriver, the flags of the Query where sets to
   process only the top-level Cell. Now process the whole hierarchy (the
   Cell is completly flattened by this operation). Secondary bug: the
   transformation was not applied to the bounding boxes, resulting of
   all the cells stacked in (0,0) ...
2014-08-15 11:48:41 +02:00
Jean-Paul Chaput fbeef95c0f Added support for MOSIS 180nm SCMOS technology (SCN6M_DEEP).
* New: In CRL Core, added configuration for SCMOS_DEEP symbolic technology
   up to 180nm "scmos_deep_018". It is postfixed "_018" because it is not
   yet compliant with 130nm (asymetrical VIA metal extensions).
     Added the associated real technology SCN6M_DEEP (TSMC 180nm).
2014-08-03 16:36:21 +02:00
Jean-Paul Chaput 206309ddd9 No longer directly use C++ exported symbols in configuration files.
* Change: In CRL Core, in Alliance.py, no longer requires the
    configuration file to uses symbols from CRL.Environment or
    CRL.RoutingLayerGauge. This way the <alliance.conf> file can be
    parsed by a different parser.
      In <alliance.conf>, for the various technologies, make uses
    of the new C++ independent constants.
* New: In CRL Core, in helpers/__init__.py, provide a "Dots" class
    (rewrite the C++ one in pure Python).
2014-08-03 16:25:26 +02:00
Jean-Paul Chaput e01f943367 Added ASCII/GDSII export capability in Unicorn.
* New: In Unicorn, in ExportCellDialog and UnicornGui add an entry to
    call the ASCII/GDSII export driver.
* New: In CRL Core, in AgdsDriver, checks for off-grid coordinates (that
    is non-integer one) and round them with a warning. This is most
    likely that the layout is flawed but it will at leat generate a
    readable ASCII/GDSII file.
2014-07-31 19:40:23 +02:00
Jean-Paul Chaput 0fab6087fa Start of Alliance/Python encapsulation layer.
* New: In Cumulus, new Alliance.py module (*not* a plugin) providing
    an encapsulation for Alliance command line tools. The other main
    feature is that it provides a "Makefile like" behavior. Based on
    the command dependencies a DAG is contructed, then a static
    ordering of the commands. Commands are then executed to rebuild
    outdated target.
      The Alliance environment supplied to the commands is read from
    the Coriolis configuration file <alliance.conf>.
      For this first evaluation version, only <boom>, <boog> and
    <loon> support are provided.
      It still not clear how to encapsulate the Coriolis tools in
    the same way.
* Change: In CRL Core, in helpers/__init__.py, change the way the static
    initialization (module) is done. All the commands are put inside
    a "staticInitialization()" function, which is then explicitly
    called by others. This is a better solution agains *no* or *twice*
    initialization. Modificate <coriolisInit.py> accordingly (as
    <Alliance.py> from Cumulus.
2014-07-27 16:23:27 +02:00
Jean-Paul Chaput a2ba6c2904 Support for Windows/Cygwin, part 3.
* Change: In CRL Core/Cyclop, Hurricane/PyHApplication and vlsisapd/ConfEditorMain,
    disable the use of GtkStyle under Cygwin.
2014-07-23 16:53:43 +02:00
Jean-Paul Chaput 520b9ae382 Restore support for both Qt4 & Qt5.
* 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.
2014-07-22 11:06:26 +02:00
Jean-Paul Chaput 25e82fc701 Complete replacement of the Chip placement Python scripts.
Finally get rid of the demonic code from Wu Yifei...
* New: In Isobar, added encapsulation of Interval (don't know how have
    forgotten it for so long).
* Change: In Isobar, In PyLayer, new PyLink_LayerDerived() function to
    create/link the C++ object to the correct derived class and not the
    base one (PyLayer) which then prevent to use the specialized methods.
    Must replace PyLink_Layer() througout all the code.
* Change: In Isobar, in PyPoint the "setX()" & "setY()" methods where
    still capitalized.
* Change: In Isobar, in PyQuery, complete the exportation of the C++
    interface. remove the code belonging to a more "boost" way of
    building the Python interface (will do that in a far future).
* New: In CRL Core, In PyAllianceFramework, export isPad() method.
* Change: In Unicorn, in unicornInit.py, protect the loading of each
    single plugin by a "try" / "except" clause to the failing of one
    plugins do not stop the loading of the next one.
      Pass the same dictionnary argument to unicornHook() as for
    ScripMain(), this is more uniform this way.
* New: In Cumulus, complete replacement of the chip placement scripts
    from Wu Yifei (at last!). The clock-tree integration is still to
    be done.
________________________________________________________________________
2014-07-21 13:18:34 +02:00
Jean-Paul Chaput d0d045b55b Starting to implement support for Windows/Cygwin.
* New: In all to CMakeLists.txt, disable the warning about deprecated
   WIN32 under cygwin.
* New: In boostrap, in ccb.py, coriolisEnv.py and builder/Configuration.py
   add recognition in uname for the values returned under Windows/Cygwin.
* New: In Documenation, in UsersGuide.rst add some informations about
   Cygwin and a section for the devel branch.
2014-07-13 13:14:49 +02:00
Jean-Paul Chaput 2b243fc0ca In protectCagedTerminal() check that the METAL3 track is free.
* New: In Kite, in protectCagedTerminal(), check that the perpandicular
    top METAL3 track is free before inserting the fixed protection.
    They are added *after* the Pre-Routed stage and therefore we have
    to check they do not cross.
* Change: In Kite, in NegociateWindow, print statistics before fixing
    segment in the pre-routed stage to get correct results.
* Change, In CRL Core, in Measures when an addMeasure is performed
    twice, let the new data erase the previous one (instead of keeping
    the previous one).
2014-07-03 00:26:15 +02:00
Jean-Paul Chaput 20d25b2053 Add NetRoutingState (Property) on Nets to tell Kite what to do.
* New: In Katabatic, add the ability to decorate some (i.e. few) nets
    with a state that indicate to Katabatic & Kite what to do with it.
    The possible states are:
    1. Fixed : all the wire are in fixed positions. The router cannot
       move them and account them as obstacles.
    2. ManualGlobalRoute : a user-defined topology is supplied. The
       wires still have to be detailed route in "Detailed Pre-Route"
       but will be skipped for the global routing and fixed for the
       general Detailed route.
    3. AutomaticGlobalRoute : ordinary nets, to be global routed then
       detail routed.
    4. Excluded : do not try to global or detail route thoses nets.
    5. MixedPreRoute : mask combining Fixed and ManualGlobalRoute.
      Not all nets have this property, only those that needs a special
    processing.
      To ease the access to the state, it is nested inside a
    PrivateProperty in the net (NetRoutingProperty), with an extension
    access class (NetRoutingExtension).
* New: In Kite, take account of NetRoutingState. Pointers to the
    net's states are strored inside an internal map for faster access.
    The property is *not* deleted when Kite is destroyed. The property
    will remains until the Net itself is destroyed.
      As a consequence, the lists that where passed to high level
    function are removed as the information can now be accessed directly
    through the net NetRoutingProperty.
* New: In Unicorn, in CgtMain, comply with the update interface.
* New: In documentation, update the User's Guide to explain the Pre-routed
    step of Kite.

Jean-Paul Chaput 7296dcd6fb Make the Python interface closely mirroring the C++ one.
* Change: In Isobar, the Python interface was not exactly mirroring the
    C++ one, now it is the case. The Python code should look likes almost
    exactly like the C++ one, the only differences remaining being due
    to the languages respective syntaxes. Note that in the case of
    constructor functions, it leads to a slightly longer notation in
    Python that it could have been (mimic the ".create()" static
    member). Main modifications:
    1. Mirror the static constructor syntax with create():
          Cell( ... )   ==>  Cell.create( ... )
    2. Correct hierarchy for constants in Instance, Net, Pin
       & Transformation. For example:
          Hurricane.PlacementStatusFIXED
                     ==> Hurricane.Instance.PlacementStatus.FIXED
          Hurricane.OrientationID
                     ==> Hurricane.Transformation.Orientation.ID
          Hurricane.TypeLOGICAL  ==>  Hurricane.Net.Type.LOGICAL
          Hurricane.DirectionIN  ==>  Hurricane.Net.Direction.IN
* Change: In CRL Core, correction to match the improved Python API
    in the configutation helpers.
* Change: In Cumulus, correction to match the improved Python API.
* Change: In Stratus, correction to match the improved Python API.
* Change: In Documenation, update for the new Python interface
    (both user's guide & examples).
* Note: We must port those changes into Chams for it to continue
   to run.
* Change: In Documenation, update the Python script support part.
2014-06-29 14:26:59 +02:00
Jean-Paul Chaput 01b97626a8 Support for Python plugins in CellViewer/Unicorn. ClockTree plugin.
* New: In Hurricane, in CellViewer, create a simpler API to graft menu
    and actions into the menubar. Mainly addToMenu() which take care of
    the QAction creation but also locate the relevant QMenu, base on
    the Qt object name. Regroup all the widget & action creation inside
    the body of the constructor, this way almost all actions can be
    removed from the attributes of the CellViewer.
      addToMenu() is supplied in three flavors:
        1. For C++ callbacks in GraphicToolEngines (with a binded
           member function method).
        2. For running Python scripts to be used by the plugin system.
        3. To insert separator in menus (to give a more homogeneous
           look).
    Remove the last remnants of Stratus scripts (unificated with basic
    Python scripts).
* New: In Hurricane, in PyCellViewer, export the interface to graft
    Python scripts into the CellViewer menu tree.
* Change: In Etesian, in GraphicEtesianEngine, use the new API to
    graft menus & callbacks into the CellViewer.
* Change: In Mauka, in GraphicMaukaEngine, use the new API to
    graft menus & callbacks into the CellViewer.
* Change: In Kite, in GraphicKiteEngine, use the new API to
    graft menus & callbacks into the CellViewer.
* New: In Cumulus, install Python scripts as plugins for Unicorn under
    <PYTHON_SITE_PACKAGES>/cumulus/plugins/.
* New: In Unicorn, in UnicornGui, make uses of the new API for creating
    menus in the CellViewer. Creates the stem menu for the P&R tools.
      Add a Python initialization mechanism to read the plugins
    installeds into <PYTHON_SITE_PACKAGES>/cumulus/plugins/.
2014-06-25 19:50:34 +02:00
Jean-Paul Chaput 2a1c7e181e Express "xEdgeCapacity" ratio as "xTracksReservedLocal" a number of tracks.
* Change: In Kite, Katabatic & Knik, express the number of tracks truly
    available to the global router by the number of tracks reserved to
    the local routage inside a GCell. Replace the ratio parameter
    "hEdgeCapacity" by an integer parameter "hTracksReservedLocal"
    (duplicate for verticals).
      It is more explicit to give directly the number of tracks that
    are to be used locally, and potentially saves us from rouding
    problems when calculating the number of availables tracks.
      Note: we cannot do that for the layer saturateRatio as it
    uses the density ratio that take account local wires, leading
    to fractional results.
* Change: In Katabatic, in <GCellGrid>, rename checkEdgeSaturation()
    into checkEdgeOverflow(), more explicit.
* Change: In Knik, in <Graph>, display the computed capacities of the
    lower left node edges (should be the same througout all the grid).
* Change: In Unicorn, in <cgt.py>, uses the new parameters names for
    edge density.
2014-06-10 16:58:52 +02:00
Jean-Paul Chaput 2af6e7eef1 Correct exception catching when creating invalid occurrence in Isobar.
* New: In CRL Core, in PyCellGauge, add the missing methods.
* Bug: In Isobar, PyOccurrence_create(), the HTRY/HCATCH block was not
    enclosing the constructor of Occurrence, which can throw exceptions.
    When an exception was thown the Python interpreter just terminate
    with the cryptic message:
      "Fatal Python error: Py_EndInterpreter: thread still has a frame"
    Reminder to myself: when such a message occurs, it means that the
    interpreter did encounter a problem, but it's related to the isobar
    interface.
2014-06-10 00:17:41 +02:00
Jean-Paul Chaput da5fb18971 Added support for Ninja in <ccb> (bootstrap). Minor fixes in CMakefiles. 2014-06-10 00:11:42 +02:00
Jean-Paul Chaput 6939025a0d Correction of SoC.css, adjust the look of the class index big letters. 2014-06-10 00:04:48 +02:00
Jean-Paul Chaput 70b896fc96 More configuration sharing.
* Change: In CRL Core, .../etc/, put all that's shared under .../common/,
    all layouts and some settings not technologically dependant.
2014-05-27 15:40:42 +02:00
Jean-Paul Chaput db4c811d75 Added a common configuartion part for kite.conf (containing the layout) 2014-05-26 14:22:19 +02:00
Jean-Paul Chaput cd9d3fc4b6 ExtensionCap support and source/target terminal flags in Katabatic & Kite.
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.
2014-05-25 15:00:35 +02:00
Jean-Paul Chaput 8bc7bd38db Add a common/ to share the trunk of symbolic technologies configurations.
In CRL Core configuration files, "display.conf", "patterns.conf" and
"technology.conf" share most of their code. So that common part is put
into "common/" and sourced from the final configuration file.
Update the documentation according the the new initialization scheme.
2014-05-22 00:13:17 +02:00
Jean-Paul Chaput 4439d3a142 Added support for multiple symbolic+real technology in configuration.
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.
2014-05-21 14:50:22 +02:00
Jean-Paul Chaput 2dd36b9624 Support of RoutingGauge, part 2.
In Katabatic & Kite, remove all hard-coded values related to track pitches.
* New: In <Session>, add more convenience function to access RoutingGauge
    characteristics.
* New: In <AutoSegment>, <AutoContact>, add support for the "depth spin",
    that is, if the source/target contacts are going "top" or "down".
    Used to compute the perpandicular pitch. Need a small modification
    of the revalidation mechanism. The observers of <AutoSegment> are
    notified when the spin changes.
* New: In <AutoSegment>, the getPPitch() method allow to compute the
    "perpandicular pitch". For now it is simply the greatest from the
    source perpandicular pitch and the target perpandicular pitch.
    Make uses of the "depth spin".
* New: In <TrackElement>, <TrackSegment>, cache the perpandicular pitch.
    Updated through the notification from the observable.
2014-05-19 17:58:38 +02:00
Jean-Paul Chaput 65d2cc98b8 Small correction for latest gcc compiler (Fedora). 2014-05-14 10:44:14 +02:00
Jean-Paul Chaput 724d92f816 Adding support for WOR_BIT in Net::Direction.
Modificate Alliance vst parser/drivers so now the wor_bit and wor_vector
are correctly loaded and written back (instead of degenrated into INOUT).
2014-05-13 17:11:48 +02:00
Jean-Paul Chaput dda3f99fd8 Update documentation for compliance with doxygen 1.8.5.
When upgrading from doxygen 1.5.x to 1.8.5 the way the documentation
is generated has underwent many changes, particularly in the headers.
* Change: In <header.html>, must include the javascripts <jquery.js>
    and <dynsections.js>.
* In <CMakeLists.txt>, as the header is customized, doxygen seems not
    copy some files like the javascripts and some images (open.png,
    closed.png). So we copy them from doxygen installation and make
    the CMakeLists.txt install them. I hope they will not change too
    much in the future.
* In <doxyfile>, disable markdown support as it do not interpret
    correctly the formating we already adopted (with a left margin
    to put command into). Use HTML_EXTRA_STYLESHEET instead of
    HTML_STYLESHEET. Enable the index (DISABLE_INDEX=NO), for the
    top header. Enable dot for inheritance diagram. Set the
    EXAMPLE_PATH=. to include the synthetic hierarchy.
    Correct the tag inclusion (faulty path in some places).
* In <SoC.css>, create style for the new header generated by doxygen.
* In the documentation, move the synthetic hierarchy into a module.
2014-05-13 16:30:41 +02:00
Jean-Paul Chaput e364edca52 Take account of fixed placement in Bookshelf & Ispd 05 parser. 2014-05-07 23:12:37 +02:00
Jean-Paul Chaput c8bcfdf174 Improved UpdateSession & exception catching. Start of RoutingGauge implem.
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.
2014-04-20 19:30:07 +02:00
Jean-Paul Chaput fee45ef117 Qt5 porting, cleanup & Tidy.
Cleanup:
* Cleanup: In <vlsisapd/src/bookshelf>, remove unused file Bookshelf.cpp
    (may have been a parser once upon a time).
* Cleanup: In <hurricane>, in Cell::flattenNets() use flags instead of
    booleans to be more readable. Allow occurrence placement checking.
* New: In <crlcore> add Python wrapper for the Ispd05 loader.
* New: In <unicorn> add option for direct loading of ISPD05 designs.
* Bug: In <hurricane/src/viewer>, RecordModel must emit
    layoutAboutToBeChanged() before changing the record contents (and
    layoutChanged() afterwards).
2014-03-26 14:47:17 +01:00
Jean-Paul Chaput 9501b88110 First barebone implementation of Etesian. Support for ISPD05 benchmark.
Details:
* New: In <vlsispad/utilities>, new objet Dots for displaying a kind
    of progress bar.
* Change: In <vlsisapd/bookshelf>, keywords are now case-insensitive.
    Added a "strict syntax" option (to be disabled for ISPD05).
* New: First working implementation of Etesian, at least for ISPD05
    "bigblue1".
* Change: In <hurricane>, in Cell::flattenNets(), no longer display
    a warning if an instance is unplaced, this does not make sense
    when the circuit is not placed.
* New: In <crlcore>, Added translator for ISPD05 bookshelf, the
    circuit is *not* placed, unlike in ISPD04 and terminal nodes
    *are* true cells.
* New: In <unicorn>, added entry in import cell for ISPD05 benchmarks.
2014-03-25 00:59:12 +01:00
Jean-Paul Chaput 4842f21a2e Update to Qt 5, requires cmake 2.8.9. New placer: Etesian.
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.
2014-03-22 11:50:36 +01:00
Jean-Paul Chaput f6ab7b87f0 Compliance with g++ 4.8.1, support for devtoolset-2
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.
2014-03-15 10:47:37 +01:00
Jean-Paul Chaput 14a5f5f7ef Documentation restructuration
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.
2014-03-11 12:21:31 +01:00
Jean-Paul Chaput 34e0edfd61 Cleanup after SVN importation, <ccb> builder script adaptation.
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.
2014-02-26 18:24:41 +01:00
Jean-Paul Chaput b4887b1180 * ./hurricane/doc/hurricane:

    - 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.
