Jean-Paul Chaput 9a872b10af Add boost157 for building under RHEL 6 with Software Collections. 2019-03-07 20:02:44 +01:00
Jean-Paul Chaput f107a68938 Reorganisation of menus in a more clear way. 2019-03-05 23:23:14 +01:00
Jean-Paul Chaput 89c730ec61 Bug in coriolisEnv.py. Avoid looping in Katana repair stage.
* In Katana::RoutingEvent::_processRepair(), do no reschedule perpandiculars
    that are already in repair mode, they may loop with repackperpandiculars().

Jean-Paul Chaput cc899710ea Update generated documenation (change for devtoolset). 2019-03-04 14:35:16 +01:00
Jean-Paul Chaput 05a7af886c Enabling the user to choose the devtoolset it needs.
* Change: In boostrap/ccb.py, change the devtoolset argument from a fixed
    behavior "--devtoolset-2" to a selecting one "--devtoolset=X" where X
    is the requested version of the devtoolset.
      Modify coriolisEnv.py to dynamically detect with which devtoolset
    we have been compiled. Idem for Makefile.package and
    FindBootstrap.cmake.

Jean-Paul Chaput fac01b10aa Compare function key adjustement for Rule in Technology.h
* Bug: In hurricane/Technology.h we define a set of UnitRule with a
    custom sorting function. STL starting with gcc 8, introduce a type
    checking of the compare function. And as everithon is template, we
    must use the exact key type and no longer a base type... So we create
    an overload for each derived type :-(

Jean-Paul Chaput 915eaf2157 Patch flute to be compatible with boost 1.65.
* Bug: In flute, a 'D' macro is defined which collides with another one
    from Boost 1.65. Rename it into 'DPARAM'.

Jean-Paul Chaput 0f4c8ec181 Added FLUTE library as a top level standalone tool in Coriolis. 2019-02-26 20:13:47 +01:00
Jean-Paul Chaput 57d52023e1 Command line support for Katana in cgt.
* New: In Unicorn/cgt.py, add "-K" option to use Katana for global and
    detailed routed (in place of Knik/Kite).
      Comment the preroute stage to ensure determinism (I often forgot
    to run this stage while in graphic mode).
2019-02-26 20:09:26 +01:00
Jean-Paul Chaput 9e6463c217 Support for density estimation for the global router.
* Bug: In Anabatic::Edge::getDistance(), remove the additionnal 0.1
    added to horizontal edges. This was for testing before the hScaling
    parameter was added (to the distance computation in GlobalRoute).
* New: Anabatic::Path_Edges, collectio to walkthrough all the edges
    between two node. More complex than in Knik as we are no longer
    using a regular grid. We may request the north bound path or south
    bound path.
      Collection returned by AnabaticEngine::getEdgesUnderPath().
* New: In Anabatic::NetData, add a new flag GlobalEstimated to tell if
    the net RMST has been computed (using FLUTE).
* New: In Anabatic::PriorityQueue, used to sort Vertexes by increasing
    distances, add a new criterion to be used in case of distance
    equality. The attractor which should be the center of the search
    area. In case of equality, we choose the Vertex which is closest
    to the attractor. Give a small improvement, and more "dendritic"
    trees.
      For a more simple implementation of the comparison function it is
    made as a static member (so no two Dijkstra objects at the same
    time...).
* Change: In Anabatic::Edge, make the estimate occupance a floating
    point number instead of an integer.
* New: In Katana::GlobalRoute, finally implement the estimated congestion
    driven router. Net RMST estimated using FLUTE.
      Use the historic cost from Knik implementation and not the one
    given in Damien's thesis, which seems not be the same and a bit
    strange.
* New: In KatanaEngine, add the ability to exclude nets from routing,
    and export it to Python.
2019-02-26 20:03:53 +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 e704306cad More robust deterministic netmap. Use classic string hash.
* Change: In Hurricane::Cell::NetMap, the hash function is now based on
    the string itself and not on the id of the SharedName. We now may
    remove the id attribute of the SharedName.
      This to ensure a more robust deterministic behavior. The sort
    order do not depend on whether we did use names before or not.
2019-02-26 19:56:29 +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 6fd383ad51 Make FLUTE an independant tool in the Coriolis git repository.
* Change: To allow multiple tools, and not only Knik, to link and use
    FLUTE, remove it from Knik and put it at top level.
      Bootsrap must compile this new tool and the library must be
    included in all CMakeLists.txt depending on Knik (and soon
    Anabatic).
2019-02-12 12:48:52 +01:00
Jean-Paul Chaput ea4fdfd230 In Anabatic, correctly set the wire width according to the routing gauge.
* New: Anabatic::AutoContact::setLayerAndWidth() to set both layer and
    VIA width/side according to the RoutingGauge. If the delta in zero,
    use the metal gauge, and the VIA gauge otherwise.
* Bug: In Anabatic::AutoContactTerminal, Anabatic::AutoContactTurn,
    Anabatic::AutoContactHTee & Anabatic::AutoContactVTee, in the
    updateTopology() method, set both the layer and the VIA with when
    there is a change of layer. Note that this default size may be
    overriden later by updateSeize() in the case of non-default width
    segments.
* New: In Anabatic::AutoSegment, new overload setLayer(size_t) to set
    both layer and segment with according to the routing gauge.
* Bug: In Anabatic::AutoHorizontal and Anabatic::AutoVertical, in method
    _makeDogleg(), make use of the new setLayer() to correctly set up
    the wire width.
      Idem for Anabatic::AutoSegment::changeDepth() and ::makeDogleg(),
    and in Anabatic::LayerAssign.

Jean-Paul Chaput c76fa034ba Implementation of a red-black tree and an interval tree.
* New: In Hurricane::RbTree, template for red-black tree. Standard
    implementation but well integrated in the Hurricane database and
    ready to be derived (both iterator and Collection support).
* New: In Hurricane::IntervalTree, template for interval tree, derived
    from RbTree.
* New: unittests tool to perform unit tests.
* Change: In Bora::ChannelRouting, now implemented with IntervalTree.
    There is something suspicious here : the "thick" version of
    addWireoccupation() seems never to be called. Have to check the
    wide wire support implementation.

Jean-Paul Chaput ac51ac3910 Analog intergration part III. Removing obsoleted vlsisapd/openChams. 2018-10-18 18:26:15 +02:00
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 dc01b60d5c Force the locale LC_ALL to be POSIX (in Hurricane::DataBase).
* Problem: In LEF/DEF, the parsers makes use of the libc "strtod()" which
    is now localized. So, if your environment is set up for French, the
    decimal separator is not '.' (dot) but ',' (comma). So floating
    numbers in LEF/DEF file are not longer recognized as such, causing
    the parsers to fail with a LEFPARS-1 error.
      To avoid that, we force the LC_ALL environment variable to POSIX
    in Hurricane::DataBase::create(). So first things that happens when
    Hurricane starts, is the environment to be reset.
      Strangely, when I try to setup only LC_NUMERIC with setlocale()
    it doesn't work. There is something I'm missing there...
2018-09-28 12:12:18 +02:00
Jean-Paul Chaput 3c849787e2 Removed generated bison file for the LEF parser. 2018-09-27 15:18:21 +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.
2018-09-20 18:24:30 +02:00
Jean-Paul Chaput 152276ddbb Corrected coordinates policy in stratus1.
* Bug: In stratus1, all coordinates given to the functions are now
    assumed to be in DbU instead of lambda. Designer must convert
    himself his coordinates from the unit of his choice into DbU.
      See helpers.l(), or helpers.m().

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 b88c3336cd No longer build doc in top Makefile as it is already build. 2018-07-12 10:02:02 +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 e88b2050c2 Tuning of Anabatic & Katana for AMS 350nm (c35b4).
* New: In Anabatic::LayerAssign, a new mode "LayerAssignNoGlobalM2V" has
    been added to manage the 3 routing metal technologies like AMS 350nm.
    The standard cells have all their connectors punctual and aligned on
    an horizontal line in the middle of the Cell. This is a design
    inherited from the channel routing times that makes global routing
    in metal2 *through* a standard cell almost impossible (except for
    directly neighboring cells). Thus, the layer assignment must move
    up all the metal2 that span more than two GCells.
* Change: In Katana::Manipulator::ripupPerpandiculars(), when a perpandicular
    has a fixed axis and it's (sole) underlying track is taken, ripup
    the other segment to ensure the perpandicular interval will be free.
      We need to do that, because in DataNegociate::update(), if the
    perpandicular is taken, the perpandicular interval will always been
    empty preventing the segment to have a valid track span (so directly
    failing).
* Change: In Katana::SegmentFsm::conflictSolveByPlaceds() the fixed axis
    segments must also been taken into account as conflicts.
       Also correct a small bug, the first conflicting segment in the
    interval was not taken into account correctly.
2018-06-11 16:44:26 +02:00
Jean-Paul Chaput 2077a19bec In AutoSegment::_changeDepth(), correct invalidation of GCells.
* Bug: In Anabatic::AutoSegment::_changeDepth(), GCells under the segment
    must be invalidated in order for the density to be recomputed.
    But we were using GCell::invalidate() which is meant for the quad-tree
    and graphic system, so the density almost never updated in case of
    a layer change, leading to over-congested GCells in the top layers
    (110% !).
       Now we directly set the Invalidated flag.
2018-06-08 12:20:37 +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 c5034a9156 Typo in CMakeLists.txt : AND instead of "and". 2018-06-06 23:22:18 +02:00
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 40b82212e3 Detect double routing attempt in Katana.
* Change: In Anabatic::setupPreRouteds(), routed DeepNets can have
    components both at Occurrence root net devel and at top level.
    If no nets remains to route, set the tool state to EngineDriving,
    which prevent any further work (except for finalize).
2018-06-03 18:28:27 +02:00
Jean-Paul Chaput 1887f45135 Exported Polygon::getSubPolygons() to Python.
* New: In Hurricane::Isobar::PyPolygon, export the getSubPolygons()
    method. Makes a list of list (maybe tuple should have been better
    to prevent user's rewrite).
* Change: In documentation/examples/scripts/, update polygons.py to
    serve as a very basic test-bench for Polygon, manhattanhization
    and sub-polygons display.
2018-06-03 12:55:28 +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.

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 41c9959e30 Added support for diagonal wires (45° and 135°)
* New: In Hurricane::Diagonal, new object to represent 45° and 135°
    segments (X routing). Althought they have source & target, they
    are not articulated like Horizontal & Vertical, due to the
    combined displacement of X and Y (diagonal).
      Maybe we should create a common class for all the polygons
    to make "::getContour()" a method.
      Now we could represent self capacitances and high frequency
    wires.

Jean-Paul Chaput 6ed8de5837 Added latest doc compilation to avoid rebuild. 2018-05-05 00:23:44 +02:00
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.

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!
