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 ?

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.

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...

Jean-Paul Chaput 19bdba0fcb Working aspect ratio and feed cell loading in Etesian.
* Bug: In Etesian::setDefaultAb(), the abutment box was miscalculated,
    it was always square.
* Bug: In Etesian::_postCreate(), improper loading of filler cells.
    Now we first try to find in memory (DataBase::getCell()) and if
    not found try to use the AllianceFramework loader.
      This is not a clean strategy. We should have something more
    clear.

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 757451b324 Upgrade of Katana for support of real technologies.
* Bug: In Katana::PreProcess::protectCagedTerminals(), the contacts of
    the fixed segment must be fixed too.
* Change: In Katana::RoutingPlane constructor, more accurate computation
    of the extensionCap (for real technologies).
* Bug: In Katana::DataNegociate::update(), the perpandicular free
    interval must be shrunk of the extensionCap of the perpandicular
    layer. This problem did show with metal1 "half-offgrid" terminals.
* Change: In Katana::runGlobalRouter(), increase the number of ripup
    passes to ten. Display the overloaded edges and the related nets.

Jean-Paul Chaput 9b2648241d In Anabatic/Katana, add support for VH gauges (real technos).
* Change: In Anabatic::AutoContactTerminal::getNativeConstraintBox(),
    when the anchor is a RoutingPad (which must be always the case),
    perform the true computation of it's position based on the
    segment occurrence. It is a important change, previously the
    area was in fact the "center line" of the connector while now
    it is really an area (mandatory for "half-offgrid" terminals of
    real technologies).
      The change is not complete yet, the area should be shrinked
    by the half size of a VIA, because the area applies to the center
    coordinate of the VIA (to be done quickly).
* Bug: In Anabatic::AutoContactTurn::updateTopology(), when a dogleg
    is created (restore connexity after a layer change) the layer of
    the VIA, based on the segments it connects to must be re-computed
    *after* the dogleg has been made.
* Change: In all files of Anabatic, when comparing two layers, no longer
    use the Layer pointer itself, but the layer mask. This allow a
    transparent management of both real and symbolic layers (which
    do share the same mask). Real metal layers (not VIAs) will be
    BasicLayer and symbolic metal layers will be RegularLayer.
* New: Anabatic::Configuration::selectRpComponent(), select the best
    RoutingPad component for metal1 terminals. Look for the metal1
    component with the biggest accessibility on-grid.
      RoutingPad using other metals are left untoucheds.
* New: New function Anabatic::Vertex::getNeighbor(Edge*) to get the
    neighbor Vertex through an Edge*. This method allows to write
    clearer code as we no longer need to access the neighbor through
    the underlying GCell.
      Also add proxies for GCell methods in Vertex.
* Bug: In Anabatic::Dijkstra::_toSources(), in the ripup stage, when
    a component with multiples vertexes is reached *and* two of it's
    vertexes are reached *at the same time* (one from which we backtrack
    and one still in the queue) extraneous edges may be created by
    _materialize(). Case occurs on snx/c35b4, "abc_5360_n903_1".
      To solve this, Dijkstra::_toSource() is modificated, the "from"
    edges of the newly reacheds vertexes are reset to NULL, *except*
    for the one we will be backtracking from. That is, the one given
    in the source argument.
* Change: In Anabatic::NetBuilder class, put the various Hooks and
    RoutingPad sorting functions as class ones.
* Bug: In AutoSegment::setLayer(), raise the SegInvalidatedFayer flag.
    This unset flag was causing AutoContactTurn::updateTopology()
    to not work as expected and making gaps, this was the cause of
    the last remaining warnings about layer connexity.

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 3e115eb056 In Etesian::AddFeed, do nothing if no feed of a suitable width is found. 2018-01-06 15:15:35 +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.

Jean-Paul Chaput a75c77626c More meaningful names in Anabatic::NetBuilder. Use of isTwoMetals(). 2017-12-19 00:28:38 +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.

* 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 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 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).

Jean-Paul Chaput 51b3a11739 In Kite & Katana, segments may have been moved outside terminals.
* Bug: In Kite::NegociateWidow and Katana::NegociateWindow, when creating
    the TrackSegment from the AutoSegment, we put it on the nearest track
    from its current position. But it may happens that the nearest track
    is outside the terminal constraint interval (in the case of "nsxlib").
    Add the terminal constraint interval check.
      This was not affecting the routing result because the segment was
    put inside the right interval afterwards. It was only generating
    disgraceful transient error messages...

Jean-Paul Chaput bc1c7838d1 Reorganisation of technology configuration files.
* Change: In CRL Core, in coriolis2/etc the file an directory structure

      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.

Jean-Paul Chaput 4e8ac63408 In CRL Core Python helpers, new showPythonTrace().
* New: In CRL Core Python helpers, add a "showPythonTrace()" function to
    custom display the Python stack trace in case of exception. It ha
    been made to look like a gdb trace.
* In Unicorn, cgt.py, use showPythonTrace().

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.

Jean-Paul Chaput de02cf5685 In stratus.buildModel(), do not always save Logical AND Physical.
* Bug: In stratus.buildModel(), the physical view was always saved, even
    only the logical one was created. Also add the ability to run the
    simulator.

Jean-Paul Chaput c12a50b64b Integrate LEF/DEF 5.8 into the tree (Apache 2.0 licensing)
* New: As, starting from version 5.8, LEF/DEF parser/drivers are
    availables under Apache 2.0 license, integrate them inside the
    project. Rewrite the Makefiles into CMakeLists.txt, build only
    the C++ version. Create an entry for the LEF/DEF doc in the
    documentation.
2017-10-30 15:38:29 +01:00
Jean-Paul Chaput 4d6b06d368 Update documentation to build on Debian 9.2 (stretch).
* Change: In documentation/CMakeLists.txt, for add_custom_targets(),
    add_dependencies() no longer allow to give files (only others
    *target* in the sense of cmake). We must use the DEPENDS option
    of add_custom_target().
* Change: In documentation/UsersGuide, it seems that docutils no longer
    handle correctly '$' and/or '_' in verbatim in the LaTeX backend.
    (i.e. they are *not* escaped, resulting in math mode errors).
    Remove those characters as we can use others...
* Commit a snaphot of the current documentation.

Jean-Paul Chaput eae5d6bf83 Added support for 2-Metal block routing in Anabatic & Katana.
* New: In AnabaticEngine::invalidateRoutingPads() this method is a temporary
    workaround for a Hurricane problems. When an instance is moved, the
    RoutingPads that use it must be moved accordingly, but they are not
    invalidated so they stay in the wrong QuadTree.
      New method ::_resizeMatrix() to be called when the associated Cell
    is resized.
* Bug: In AutoHorizontal::getConstraints() and AutoVertical::getConstraints(),
    the *target* constraints where never merged.
* Change: In AutoHorizontal::getCells() and AutoVertical::getGCells(),
    now return a boolean to tell if it was ok (must not encounter a NULL
    GCell while progessing from source to target).
* New: In Anabatic::Configuration and Anabatic:Session, create new methods:
     - getDHorizontalLayer()
     - getDhorizontalDepth()
     - getDHorizontalWidth()
     - getDHorizontalPitch()
     And so on for Vertical and Contact.
       They supply depth-independant informations about the H/V layers to
     build the initial detailed routing.
        The AutoSegment::create() methods have been modificated accordingly.
* New: In Anabatic::GCell, add two new types "StdCellRow" and "ChannelRow"
    for implementing 2-Metal blocks.
      Rename the GCell::setXY() method in GCell::setSouthWestCorner(),
    move the contents of GCell::updateContactsPosition() into it and
    suppress it.
      WARNING: In case of a GCell shrink this may cause problems. But for
    now we only expand...
      New method GCell::getNetCount() to count the number of Net going
    though the GCell.
* Change: In Anabatic::Edge, add specific support for capacity of 2-Metal
    routing channels.
* Change: In Anabatic::Dijsktra various methods, replace the "gcell->isMatrix()"
    calls by "not gcell->isAnalog()". Add more check so that the methods
    pertaining to the analog routing (GRData) are not called in digital
    mode.
* New: In Anabatic::Dijkstra::materialize(), add support for 2-Metal specific
    cases. That is, always break in case of vertical pass-through or
    U-turn. The global routing must always be broken in H-Channel.
* New: In Anabatic::GCell & Anabatic::Edge, make use of the Session mechanism
    to ensure the revalidation. The "::revalidate()" method is then moved
    as "::materialize()" (overload of Go) and "::_invalidate()" becomes
    "::invalidate()"
* Change: In LoadGlobalRouting, cosmetic rename of SortHkByX in SortHookByX.
* New: In GCellTopology, added support for building 2-Metal topologies.
    * ForkStack is now an object attribute as many methods do need it.
    * To push segments/hook on the stack, a new method "push()" is
      available. Perform NULL and fromHook checking. Can also setup
      _southWestContact or _northEastContact if it is the "from" edge.
    * N/S/E/W edges are now vector as in digital channel mode there
      can be more than one.
    * Added build topological build methods:
      - doRp_2m_Access() RoutingPad stem access.
      - _do_2m_1G_1M1() North or south access.
      - _do_2m_2G_1M1() North AND south access.
      - _do_2m_xG() H-Channel routing.
* New: In Anabatic::Matrix, new ::resize() function, as Cell can be resizeds.
* New: In Anabatic::Vertex, new static method ::getValueString() for a
    friendly text rendering.
* New: In Katana::DigitalDistance, support for channel routing.
* Change: In KatanaEngine::digitalSetup() and KatanaEngine::runGlobalrouter(),
    for channel routing, calls to setupPowerRails() and
    protectRoutingPads() must be called after the core block has
    been fully dimensionned.
      ::runGlobalrouter() contains the code tasked with the grid creation
    and channel sizing.
* New: In KatanaEngine: Added support for core block, for 2-Metal routing.
    May be expanded for over-the-cell routing in the future.
      Added methods :
      - isDigitalMode()
      - isAnalogMode()
      - isMixedMode()
      - isChannelMode()
      - getBlock() / addBlock()
      - setupChannelMode()
      - createChannel()
* New: In Katana, new class Block to manage core blocks and perform
    channel routing.
* New: In Katana::Session, new convenience method "isOpen()".
2017-08-18 23:56:23 +02:00
Jean-Paul Chaput 809a91c9c1 Added Routing Gauge for 2-Metal technologies only.
* New: In CRL Core, etc/cmos/kite.conf new routing gauge "sxlib-2M" for
    two metals only technologies.
* New: In CRL Core, python/helpers/kite.py, new parameter to set the
    routing gauge to be used: "kite.routingGauge" (default: "sxlib").
* Change: In CRL/AllianceFramework.cpp, forgot to put the Cell gauges
    and RoutingGauges in the object Records (Inspector).
* New: In pyCRL/PyAllianceFramework.cpp, export the setRoutingGauge()
    function.
2017-08-18 18:16:43 +02:00
Jean-Paul Chaput 2127fa916b Inspector support for map<> with default sort.
* New: In Hurricane/Common.h, added inspector support for map<> using
    the default sort mechanism (less<>).
