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.

Jean-Paul Chaput 3e4430c089 Fix huge memory link in Collection iterator.
* Bug: In Hurricane::Collection::iterator, the iterator use a locator from
    a getLocator() not wrapped inside an auto_pointer like GenericLocator.
    So the destructor of the iterator must take care of the deletion.
      This was showing more and more as we converted forEach() into the
    C++ 11 for syntax.
      Seems to decrease the memory use by almost a factor 2...
* Bug: In Dijkstra::_cleanup(), as a double security, cleanup the queue.
2019-03-23 15:43:00 +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 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 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 :-(
2019-03-04 12:45:02 +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.

Jean-Paul Chaput 2f9a7076cb Forgoten hurricane analog generated documentation. 2018-11-29 12:03:26 +01:00
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 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 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 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.

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 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.
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.
2018-05-15 13:12:00 +02:00
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.
2018-05-07 13:46:44 +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.
2018-05-04 17:06:41 +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.

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.

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 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 864b031b6a Disable backtrace generation in Hurricane::Error constructor.
* Change: In Hurricane::Backtrace constructor, add a boolean parameter
    to enable/disable the actual backtrace generation.
* Change: In Hurricane::Error constructor, disable by default the
    backtrace generation. The backtrace is useful when the Error is
    thrown, and the program therefore stopped. But in many case we
    just issue the error message on the console and try to continue.
    But if the backtrace is enabled, it terribly slow down the
    program.
      Have to think about an clean way to re-enable the trace only
    when the exception is thrown.
2018-01-06 15:13:20 +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 4c57b0651a Modularize the global to detail routing converter.
* New: In Anabatic, rename GCellTopology to NetBuilder, expose  the class
    (no longer in a local namespace).
      NetBuilder become a base class performing the walkthrough the Net
    tree. Derived class are tasked to build routing for specific gauge.
      NetBuilderHV is created to manage all gauge with metal2 horizontal
    and metal3 vertical.
      In our terminolgy we consider that the first routing metal is
    metal2. Metal1 is used inside the standard cells.

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 141cb6e7c2 In Occurrence_Contains(), accept everything when _instance is NULL.
* Bug: In Hurricane::Occurrence_Contains(), when the Instance to match
    is set to NULL, that means we have to accept *all* instances instead
    of rejecting them all. This bug was making the Cell::flattenedNets()
    to do nothing in digital mode.
