Jean-Paul Chaput f87bcf717c Complete the modularization of the detail routing converter.
* New: In Anabatic::NetBuilder, set all the attributes as private and
    create accessors and mutators.
      Finish virtualising all GCell build methods and transfer them
    into the NetBuilderHV class.
      Build methods now return a boolean to tell if the GCell was
    processed or not, to allow cascading in the "big switch".
      Reorganise the "big switch" in separate sections only partially
    cascading.
      Truly fuse the *big switch* for channel routing and over-the-cells.
      Create a new method "_do_globalSegment()" to delagate the
    drawing of global segments between two GCell to the derived classes.

Jean-Paul Chaput e17a50ca0b Suppress all static attributes & methods from Anabatic::NetBuilder. 2017-12-17 12:51:04 +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 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 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()".

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

Jean-Paul Chaput d776996658 Cell::flattenNets() is now able to work on one instance only.
* New: Occurrence_Contains filter that tells if an instance is part of
    an Occurrence. Checks for two cases:
      - The Instance is part of the *path* of the Occurrence.
      - The Instance is the associated entity itself.
* New: In Cell::flattenNets() adds a new parameter Instance* to
    allow partial flatten of one instance only.
* Bug: In Anabatic::Disjstra::_materialize() check that the
    NetRoutingState exists before trying to access it...

EricLaoGitHub e1724ca785 Dijkstra and Net can manage different wire width.

Jean-Paul Chaput 8d4fdf3471 TrackCost clean support for symmetric and wide segments.
* New: In Katana::TrackCost, the TrackElement and it's optional
    symmetric are now kept as attribute of a TrackCost. The cost
    is completly computed inside the constructor.
      TrackCost now support any mix of symmetric event and wide
    segments.
      The cost is now computed by adding directly to the current
    one instead of creating secondaries that are merged afterwards.
    As a consequence, remove all copy construction and merge
    capabilities.
      All the various methods used to compute the cost are renamed
    "addOverlapcost()" in all the various related objects.
      As a reminder, the overal cost method call is as follow:
        1. TrackCost constructor on a TrackElement.
           2. Call TrackElement::addOverlapcost()
              3. For all Track under the TrackElement, call
                 Track::addOverlapCost()
                 4. For all other TrackElement intersecting with
                    the overlap interval call:
                    TrackElement::incOverlapCost()
                    5. The callback overlap function for segments
                       is called (defined in NegociateWidow).
      Don't confuse:
      - TrackElement::addOverlapCost(), which compute the cost of
          inserting the segment inside a track (or a set of).
      - TrackElement::incOverlapCost(), which compute the cost of
          overlaping with this already inserted segment. It is the
          other way around of the previous one.
* Change: In Katana::SegmentFsm, use a vector of pointer to TrackCost
    instead of an object to avoid copy construction.
2017-06-10 12:27:25 +02:00
Jean-Paul Chaput 8a73b03fd8 Synchronize priority of TrackSegments connecteds through doglegs.
* Bug: In Anabatic::Dijsktra, correct the indentation in cdebug calls
    (lots of them causing a big shift right).
* New: In Anabatic::TrackSegment, new helper structure SideStack to
    manage a set of aligned GCells and their various sides sizes.
* Change: In Anabatic::TrackSegment::computeOptimal(), more accurate
    computation of attractors from global segments and variable size
    GCells using SideStack.
* Change: In Katana::DataSymmetric::checkPairing(), increase the tolerance
    for misaligned symmetrics from 2 to 5 tracks (should be enough for our
    narrow channel routing).
* New: In Katana::TrackSegment, add a first flag to enable locking of
    priority. If it is set, calls to either "computePriority()" or
    "forcePriority()" will have no effect. Added the uint32_t flags
    paraphernalia.
* New: In ::computeNetPriority(), overall function to control the call
    of TrackSegment::computeAlignedPriority(). The call is done from
    NegociateWindow::run().
* New: Katana::TrackSegment::computeAlignedPriority(), order the
    TrackSegments aligneds through doglegs to the one with the highest
    priority is routed first and others progressively from him. Done by
    forcing an ever decreasing priority on the aligneds ones.
      The amount of decrease is small so the aligned segments got routed
    (ordered) in close, if not contiguous, sequence. Priority is locked
    for the order to remain.
* Bug: In Katana::TrackSegment::computePriority(), correct computation
    of the priority when there is more than 10 free tracks
    (a DbU::toLambda() call was missing, leading to very big priorities).
* Change: In katana::TrackCost CTOR, do not compute a distance to fixed
    in the case of analog segments, this is backfiring.
      Slight change of the compare function when delta differs. Seems
    to improve a little.
2017-05-30 22:33:06 +02:00
Jean-Paul Chaput 1e49da1976 Select S/T in AutoSegments_Aligneds. Priority moved to TrackSegment.
* In Katana::AutoSegments_Aligneds, allow the the caller to select
    if we are propagating through source or target only (or both).
    Note that if no flag is given, it is assumed that we want to
    propagate the old way on both source and target.
* In Katana::TrackElement, Katana::TrackSegment and Katana::RoutingEvent,
    move the event priority from RoutingEvent to TrackSegment.
    Add accessor and mutators associated in TrackElement (virtual
    methods).

Jean-Paul Chaput e12e45e495 Rename SymmetricStage into PairSymmetrics, plus small cleanup. 2017-05-26 13:32:30 +02:00
Jean-Paul Chaput 3e825cc228 Katana routing algorithm adjustements for analog routing.
* Bug: In Hurricane::Interval, the ::getSize() method was returning a negative
    length when the Interval was empty. Now return zero. This was causing
    slight cost functions side effect when computing the overlap of a segment
    with another one belonging to the same net (i.e. shareDelta)
* Bug: In Katana::AutoSegment::computeOptimal(), checks that the optimal
    position for the axis is indeed inside the GCell interval.
* Bug: In Katana::DataSymmetric::getSymmetrical(Interval&), reverse the shrink
    applied to GCells sides. Interval are of the type [min:max[ so after
    symmetric transformation they become ]smax:smin]. Apply a correction so
    that they are [smax:smin[ and could be merged with the paired interval
    (the one without symmetry applied).
* Bug: In katana::TrackCost::consolidate(), the overlap (now) always positive,
    and must be *substracted* to the "delta" (not *added*).
* Bug: In Katana::_computeNetOptimals(), now skip the already processeds
    AutoSegments instead of re-processing them.
* New: In Katana::AutoSegment::computeOptimal(), improved computation of
    the axis hint:
      - For analog net, propagate through the simple doglegs to find
        attractors.
      - Restrict the allowed interval to the union of GCell sides and
        segments constraints that are terminals.
      - Consider a local as "long" if it's length exceed 20 the P-pitch.
        (maybe make that a tool parameter).
2017-05-23 00:20:31 +02:00
Jean-Paul Chaput e78c3f21ef Added analog type on segment NetRoutingProperty.
* New: In Anabatic_AutoSegments collection, added a Flag to the constructors
    to allow different behavior between digital and analog modes.
      For "Aligneds" and "Perpandiculars" collections, now manage a new
    Flag WithDoglegs to follow aligned globals through local doglegs
    (for analog nets).
      Adjust the log level of collections to 144 (formerly 145).
* New: In Anabatic::AutoSegment, new flag SegAnalog for segments that are
    part of an analog net.
      Note that with this flag, we reach the 32 bits limit...
* Change: In Anabatic::Constants, Flags are now declared as BaseFlags
    objects and *not* uint64_t. This avoids overload resolution problems with
    arithmetical overload of the operators.
      The BaseFlags/Flags types are now completly "isolated" from the
    uint64_t, it has the advantage of showing where unwanted previous implicit
    conversions where occuring.
* Change: In Katana::Constants, Flags values are now of BaseFlags type instead
    of uint64_t.
* Change: In Anabatic::Dijkstra, lots of log cleanup.
* Change: In Anabatic::GCell::getSide(), make the "shrink" parameter visible
    to allow to substract the topmost and rightmost track for axis span
    computation in AutoSegment::computeOptimal(). Used for analog mode.
* Change: In NetRoutingState, added a flag for analog mode. Use uint32_t
    for the flags type.
* New: In Isobar, export the NetRoutingState and NetRoutingExtension objects.
2017-05-20 12:33:12 +02:00
Jean-Paul Chaput d07cdf03e9 Replace "unsigned int" by "Flags" in all AutoSegments collections.
* Change: In Anabatic::AutoSegments collections, change the type of all
    the flags that where in "unsigned int" (32 bits) to Flags (uint64_t)
    as there is now more than 32 flags for functions.
* New: In Ababatic::Constants, added new flag Flags::WithPerpands, which
    makes the number of flags tip over 32 bits, thus making mandatory
    to uses Flags and not unsigned int.
* New: In Anabatic::AutoSegments_Perpandiculars, manage a new flag
    Flags::WithDoglegs to allow to propagate through global segments that
    are connecteds via doglegs on local segments. Meaning that there is
    a good chance that they could be aligned.
      Slighly change the way we propagate on aligned segments: no longer
    check for VTee or HTee, but only for same direction and layer as
    master.
* New: In Anabatic & Katana, replace all the "int", "long" and their
    variants by the less implementation ambiguous "int32_t", "int64_t"
    (and variant). This should help to better detect bit trucation in
    flags.
      Use the type to give a hint about the flags kind:
        - Type "Flags", for flags shared among Anabatic & Katana
          functions/methods (may also appear in some objects states).
        - Type "uint32_t" for flags belonging to an object internal
          state of from Hurricane functions flags (those should be
          grouped in a Flag subclass in a perfect world).

Jean-Paul Chaput f1b2035cb0 Support for profiling the priority of events in Kite & Katana.
* New: In Katana::Configuration, added "katana.profileEventCosts" to
    triggers the event's profiling.
* New: In Katana::NegociateWindow::_negociate(), save a profiling
    trace of all the events and their priority, separated by metal,
    for later analysis (see doChip.py in alliance-check-toolkit).
* New: In Katana::RoutingEvent::Key::Compare(), start implementing
    new segment freedom degree functions.
* Change: In Hurricane::Net::_getString(), put a more complete
    information about the Net instead of just only it's name.
* Bug: In Katana, reorder the various stages so that they are
    executed in the exact same sequence as in "doChip.py" so now
    routing in graphic mode and text mode gives exactly the same
    results.
* Bug: In Katana::PyKatanaEngine, runGlobalRouter do not take any
    argument.
2017-05-09 18:33:55 +02:00
Jean-Paul Chaput db8e51524f Deterministic destruction of Components.
* Change: In Hurrican::Component::_preDestroy(), the cascaded destruction
    of slaves Components and subsequent ring merge and Rubber creation
    was using set<> sorted on pointer values. This was making the order
    of destruction of the slaves components non-deterministic. Now the
    sets are sorted according to their id (see Entity).
* Change: In Hurricane::SharedProperty, the _ownerSet is now a vector<>
    instead of a set<>. This will slow the search process, but hopefully
    this is needed only during construction/destruction of a Property
    so the slow down shouldn't be too much.
      This has also an impact on Hurricane::Relation.

Jean-Paul Chaput ef69a6d586 Support for symmetric routing in Anabatic/Katabatic.
* New: In Katana::SegmentFsm, the object is now able to handle two events
    at the same time. The master and it's symmetric. When there is no
    symmetric, the corresponing data is just left blank. This makes a
    bigger object, but as there is only one when running, it is not an
    issue.
      Candidates tracks are now an vector of array<2> (pairs), the
    TrackCost::Compare() functor has to be wrapped through CompareCostArray.
    The compined TrackCost of the two tracks is accumulated into the first
    element.
      Everything related to events gets duplicated: _event is now _event1
    and _event2, and so on.
      As there can be now two Manipulator actions done with SegmentFsm,
    this class now completly hide the Manipulator level from the
    RoutingEvent processing.
      New function ::bindToTrack() to perform the track insertion.
* New: In Katana::TrackCost, add a new ::merge() function.
* New: In Katana::TrackElement and Katana::TrackSegment, add symmetric
    management. Allows to know if a TrackElement has a symmetric and to
    access it.
* New: In Katana::DataSymmetric, add new overload for ::getSymmetrical()
    to handle DbU::Unit and intervals.
* Change: In Katana::RoutingEvent, remove all direct uses of Manipulator
    objects. Now any change to the event associated segment must go through
    call to Segment Fsm.
* Change: In Katana, adjust the debug level so internal informations are
    put below level 156.
* New: In Hurricane::DbU, in ::getValueString(), special display when the
    value is Min or Max (more helpful than a gigantic number).

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

Jean-Paul Chaput 44a2f574bc Accurate measuring of memory usage under Linux.

    of sbrk() gives erroneous results. Under Linux, now read the
    /proc/[pid]/statm which gives the real size of the virtual memory
    of the process. There is also code for reading /proc/[pid]/mmap
    but it gives only the resident size of the process (i.e. swapped

    a AutoContactTerminal to be set (and fixed) outside it's constraint
    Box. Be aware that this may generate gaps in the routing.
      Stored using the UserNativeConstraints mechanism.
* New: In Anabatic::Session() new method getNearestgridpoint() to
    easily compute the nearest grid point from a position.
* Change: In Anabatic::AutoSegment::_revalidate(), use layer mask to
    compute the spin of the segment instead of the layers (more robust
    for analogic).
* New: In ::GCellTopology::doRp_Access() new method to create terminal
    contacts in _doDevice(). Issue more warnings and force the terminal
    to on grid (even if it create gaps). This a temporary hack.
2016-10-05 23:43:07 +02:00
Jean-Paul Chaput 47c9961ef3 First intergration of the Analogic router parts.
* New: In Anabatic::AutoSegment, introduce a the kind (associated to a
    flag) "LongLocal". Analog GCells can be very wide, so at least some
    carefuly choosen long local segments must be took into account as
    attractors in the computation of the optimal axis.
* New: In Anabatic::AutoSegment::computeOptimal(), take LongLocal into
    account as attractors.
* Change: In ::GCellTopology constructors compare the layers of the
    RoutingPads using layer masks instead of Layer pointers. Allows to
    find both "METALx" (symbolic) and "metalX" (real).
* Change: In ::GCellTopology::_doHChannel(), _doChannel(), _doStrut()
    and _doDevice(), tag long locals as "LongLocal". This need to be
    reviewed as it as bind done a bit too quickly.
* Change: In Anabatic::AutoSegment, due too a much bigger span of the
    analogic GCells the _optimalMin & _optimalMax bitfields must use
    16 bits instead of 8 (they where overflowed).
* New: In Katana, reorganisation of the initialization procedure to fit
    both digital and analogic cases. Create an analogInit() method.
* Change: In Katana::RoutingEvent, the _tracksNb and _tracksFree bitfields
    where too short for the Analog GCell size, now uses 16 bits instead of
    6.
* Bug: In Katana::GraphicKatanEngine::drawGCell(), skip drawing of a
    GCell if *both* width and height are under 150 pixels.

  Detailed Routing can be performed for analog circuits.
  The router does not take into account analog constraints yet.
  Warnings on "metal2" should be corrected in the future.
  Types of GCell considered by the router are: Device, VChannel/HChannel and Strut.
  The analog circuit MUST be organized in a slicing structure.

Jean-Paul Chaput 6db4ae542b Correct bug in AutoHorizontal::getGCells() line probing.
* Bug: In Anabatic::AutoHorizontal::getGCells(), the y coordinate used
    to perform the line probing for neighboring GCells, cannot use the
    segment constraints because they are not correctly set this early.
    Instead we have to rely on the global router having put them in the
    correct position (i.e. at the center of the GCell side).
      The y position must also be epsilon-decreased if it is on the
    border of the nothernmost GCell.
      This apply to AutoVertical as well.
* Change: In Anabatic::GCellTopology CTOR, when counting the RoutingPads
    of a GCell, compare gauge layers using their masks instead of the
    Layer itself. This allow for Analogic layers to be recognizeds.

Jean-Paul Chaput bff9a38742 Forgot to perform Track re-order after removing zero-length segments.
* Change: In Anabatic::Autocontact, replace getMinDepth() and
    getMaxDepth() by getDepthSpan().
* New: In Anabatic::AutoSegment::canMoveUp(), add an optional check of
    low up density (Flags::CheckLowUpDensity). Allows to move up a
    segment if the up density is (very) low, and in this case it's more
    efficient than breaking it to fit in the lower layer.
      canMoveUp() is now able to perform the same work as canPivotUp()
    if *not* supplied the flag Flags::IgnoreContacts.
* New: In Katana, in GlobalRouting::DigitalDistance() now take into
    account the cost of a VIA (currently set to 2.5). Need to known the
    Net currently routed in the DigitalDistance object itself.
* Change: In Katana::Track::Element::canPivotUp(), now also takes a flag
    parameter.
* Change: In Katana::Manipulator, new flag IgnoreContacts to mirror the
    one of Anabatic.
* Change: In Katana::SegmentFsm, allocate once a Manipulator object instead
    of many times on the fly.
      In SegmentFsm::_slackenGlobal(), in the slacken state, if the up
    density is (very) low, bypass to move up instead of slackening.

    The register file having a pathological case of terminal placement:
    many punctual terminals aligneds in METAL2 *and* a grid of METAL2 and
    METAL3 blockages near below...
* Bug: In Katana::Session::_revalidate(), after removing the zero-length
    segments, forgot to re-order the track, leading to many stranges effects
    as the indexes where no longer coherent in the Track.

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

    connected only through one, all others must be discarteds. The right
    one will have it's connex id set, all the others will stay to -1.

Jean-Paul Chaput 44500a2329 Correct management of last E/N GCell boundaries.
* Bug: In Anabatic::GCell, new functions getConstraintUMax() to return the
    correct bounding box for the last north/east GCell. The GCells do not
    own their north/east edges, except for the last ones. Thoses functions
    must distinct from getUMax() because for them, the shrink is always
    applied. getConstraintBox() uses the "getConstraintUMax()" functions.
* Bug: In Anabatic::AutoContact, initialize the constraint box from the
    new GCell::getConstraintUMax(), to manage correctly the boundaries
    of the nothernmost & easternmost GCells. The problem was showing for
    pins on the north/east side of a circuit, the constraint
* Bug: In Anabatic::AutoContactHTee, Anabatic::AutoContactVTee and

Jean-Paul Chaput 48f3a2bc3c Anabatic transient commit 18. Port of Kite (Katana), Yeah, Baby! Yeah!
* Bug: In Hurricane, in StaticObservable::getObserver(), if the slot
    pointer is NULL, do not try to access the owner. Returns NULL, so
    the caller can be aware of the situation...
* Change: In Hurricane, in BreakpointWidget & ExceptionWidget some
    cosmetic changes (fonts and window sizes).
* Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account
    the constraints from the source AutoContact, as it holds the constraints
    transmitted by the RoutingPads and sets up by propageConstraintsFromRp().
    It is likely to be a bug affecting the original Katabatic as well.
* Change: In Anabatic, in RawGCellsUnder(), check that the segment is not
    completly oustside the cell abutment box and truncate the coordinates
    to the part that is inside. Use the "shrink" if we reach the east/north
    border.
* Change: In Anabatic, in Configuration, no more decorator because we will
    use a true derived relationship. Katana *derives* from *Anabatic* and do
    not *decorate* it, so the Configuration can do the same. It also implies
    that we directly create a Katana engine, not an Anabatic one.
* Change: In Anabatic, in Session, do not allow the opening of the Session
    in a standalone fashion (with a static method). Instead it must be opened
    using the relevant method of the Anabatic/Katana engine. This ensure we
    are opening the right Session type.
* Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment
    is not part of the collection by default, but will be included if the
    Flags::WithSelf is set.
* Change: In Configuration, all the flags value are now defined in two steps.
    Declared in the header and initialized in the module. This is to prevent
    the fact that on some cases, in relation with the Python "extern C" part
    modules, we need a true allocated variable. It was causing weird linking
    problems.
      A side effect is that they can no longer be used as entry is switches,
    have to replace them by if/else.
* New: In Anabatic, new GCell::getNeighborAt() utility function.
* Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with
    the grid type... Back annote all the edges capacity (north & east) with
    the reserved local capacity.
* New: Complete portage of Kite over Anabatic. The new engine is christened
    "Katana" for Kite-Analogic. When it's capabilities and performances
    will be on a part with Kite, it is to completly replace it (and take
    back the "Kite" name). Preliminary tests seems to show that, contrary
    to intuition (because built on a more complex/slower grid), it is even
    slightly faster than Kite 8-).

Jean-Paul Chaput db098db351 Anabatic transient commit 15. Introduce Net ordering for global route.
* New: In Anabatic:
    - In AnabaticEngine, create a new NetData information for storing
      the static ordering of nets (for the global routing). The order
      is the half perimeter of the search area divided by the number
      of RoutingPads. The order is static once it as been computed in
      the first place (even through ripup stages).
2016-07-31 18:43:44 +02:00
Jean-Paul Chaput 84dad2249e Anabatic transient commit 14. Change model for long wires.
* Change: In Anabatic:
    - Long wires, going straight accross multiple GCells were splitted
      into a long sequence of segment+contact, one for each gone-through
      GCell. It was memory-consuming and algorithmically inefficient.
      Now there is only one straight wire.
        As a consequence, Edges now store the list of all segments
      going through them. That way we do not need to load a Net into
      Dijkstra before riping up some of it's segment. The ripup mechanims
      can now be implemented right at AnabaticEngine level, without
      dependencies over Dijkstra. Note that long wires are automatically
      broken in two if we need to attach a new branch on it (breakAt()).

Jean-Paul Chaput 9808fb12b2 Solve the template lookup problem in tstream.
* Bug: In Hurricane, in tstream (Commons.h), in the *template* overload of
    operator<<(), do not use the operator<<() of ostream as it will be
    looked up in "stage 1" (template definition) and so will miss all the
    overloads added later and built over getString<>(). Instead, make use
    of getString<>(), which, as another template will be looked up in
    "stage 2" (template instanciation) and at that point will have all the
    needed template specialisation of getString<>().
      We also need to define new stream manipulators to be able to create
    a matching template overload not dependant from the implementation.
    To avoid name clashes, we prefix a 't'. For now, only 'tsetw()' is
    refined.
      As a side effect, we cannot directly print bit-fields into the stream,
    we must go through an intermediate variable (happens once in AutoContact).

Jean-Paul Chaput abf58190eb Anabatic transient commit 10. Ripup & reroute support in Dijsktra.
* New: In Anabatic:
    - In AnabaticEngine, keep track of overflowed edges.
    - In AnabaticEngine, getNetsFromedge() to lookup all nets going
      through an Edge.
    - In Configuration, read the Kite "reserved local" parameter to
      decrease the Edge capacity (it's a guessing of the cost of the
      local routing).
    - In Edge, add an attribute to know if there is an associated
      segment of the current net (set by Dijkstra::_traceback()).
      Transparently manage the overflowed edges.
    - In GCell_Edges, correct a filtering bug when not all sides are
      selecteds.
    - New GCell::getEdgeTo() to find the edge between two adjacent
      GCells.
    - New GCell::unrefContact() to automatically removes global contacts
      no longer used by any global segments (used during the ripup
      step).
    - In Dijkstra::load(), now able to "reload" and already partially
      or completly routed net (look for Contact of "gcontact" layer
      and their attached segments).
    - In Dijkstra, keep the last net loaded until the next one is.
      Put the cleanup operations in an isolated function "_cleanup()".
    - In Dijkstra::_selectFirstsource() and run(), load first source
      component made of multiple vertexes.
    - In Dijkstra::_trackback(), link the Net segments to the Edges.
    - New Dijkstra::ripup(), Dijkstra::_propagateRipup() to perform
      the ripup of one edge of a Net (must be loaded in Dijkstra first).
      Dijkstra::_tagConnecteds() setup the connexId of a set of Vertexes
    - that are connecteds through edges *with* segments.
    - In GraphicAnabaticengine & GlobalRoute.cpp, embryo of a global
      routing tool with ripup & reroute.

Jean-Paul Chaput 379effd92c Anabatic transient commit 9. Dijkstra::_traceback() replaces _toWires().
* Change: In Anabatic:
    - In Dijkstra, replace _toWires() by _trackback() which is called
      immediatly on reaching a target.
    - In Constants & GCell, added flags for typing the GCells. We now
      have:
        * DeviceGCell, for analogic devices.
        * ChannelGCell, for resizable routing channels.
        * StrutGCell, for fixed spaces in analog designs.
        * MatrixGCell, for square tile in digital designs.

Jean-Paul Chaput 601e3d3da1 Anabatic transient commit 8. More Dijkstra bugs correcteds.
* Bug: In Anabatic:
    - In _propagate(), on reaching a target, forgot to remove it from
      the queue before pushing it back with the new distance. It also
      simplificate the core algorithm as target as treated normal nodes.
* New: In Anabatic:
    - Update cdebug to use the fastest macro version.
    - More readable drawings of GCells and Edges.
    - Added timer support.
    - The distance is now computed in DbU::Unit (aka long) and not in
      normalized float.
    - The distance function is now a callback (std::function<>) that
      can be changed (a default is provided at initialization).
    - New concept of branch in the agglomerated connex component.
      Each trace back part create a "branch" (tagged with a "branchId").
      When a node is reached with the same distance, but from two
      different branches, choose the the branch that was lastly created.
      This create a slightly different tree which grows outward from
      the newest branches.
    - Makes the horizontal edges *slightly* longer than the vertical ones
      to skew the tree to use vertical edges, as it is usually less
      congested than the horiontal one (due to metal1 cell terminals).
      It is also my understanding that it is useful to reduce the
      number of vias, whithout introducing a via cost.
* New: In Bootstrap:
    - Script sprof.py to perform sprof & demangle libraries execution
      profile.
* ToDo: In Anabatic:
    - Corner optimization. Sometimes when two corners are possible, the
      wrong one is choosen. That is, one of it's edge cannot be used for
      further grow of the tree.

Jean-Paul Chaput c5a9e0b617 Anabatic transient commit 7. More Dijkstra bugs correcteds.
* Bug: In Anabatic:
    - Activate the searchArea to limit the area explored by the Dijkstra.
      Uses the bounding boxes of the vertexes/gcells instead of the ones
      the RoutingPads.
    - Always detach contacts from the rings in load(), even if the vertex
      is already marked as target.
    - On reaching a target (non-negative connexId), do not forget to update
      the distance to source.
    - In Edges locator, added support for side selection (needed by the
      monotonic feature).
* New: In Anabatic:
    - Hide the atomic Dijkstra methods (made private).
    - Implementation of the monotonic mode in Dijkstra (for bipoints only).
    - Added a separate function for distance computation between two vertexes,
      now take account of the VIAs costs.
2016-06-10 18:27:06 +02:00
Jean-Paul Chaput d9e124797b Anabatic transient commit 6 "Somatoline, ca marche!".
* Bug: In Anabatic:
    - In Dijktra::load(), do not create Contact while looping over the Net's
      components (for RoutingPads).
    - In Dijkstra::propagate(), reset the connexId of reached Vertexes
      on updating the stamp to avoid using connexId from previous runs.
        Push the vertexes on the queue while backtracking (with a distance
      of 0.0). Do not reset the "_from" as we need it in Dijkstra::toWires()
      to know how were the routing is.
    - In Edge::getDistance(), convert to float more early so the normalisation
      do not always end up in zero.
    - In GCell::_add(), when the axis of the new edge is equal to one already
      on the given side, adds it *after* the existing edge and not before.
      (to be coherent with the way GCells are split in two)
    - In GCell::hcut() and GCell::vcut(), create an Edge if is equal to X/Y Max,
      *but* the new chunk is flat. The new chunk is then expected to expand
      "below".
    - In GraphicsAnabaticEngine::drawGCell(), display the id of the GCell in
      a small box at the center of it's bounding box. Nothing displayed for
      flat GCells, to avoid cluttering.

Jean-Paul Chaput aa20813342 Anabatic transient commit 5.
* Bug: In Anabatic:
    - In Dijkstra/Vertex, use the new Observer for fast access from the GCells.
    - In Dijktra::propagate() loop detection.
    - In Dijkstra, reset the "_from" of vertexes between two propagates on
      the same Net (otherwise: loops...).
    - In Matrix, there must be two different way of calculating an index from
      a position. One for the min, which is rounded to superior. And one for
      the max which is rounded to inferior.
    - In Matrix::updateArea(), checks for invalid indexes.

Jean-Paul Chaput a4655aec8b Anabatic transient commit 2.
* Change: In Hurricane, in CellWidget, enable the drawing of ExtensionGos
    according to the the threshold paramaters (as layers do).
* Change: In CRL Core, provide DrawingStyle for Anabatic::GCell &
    Anabatic::Edge. Use the exact name of the ExtensionGo.
      In kite.conf, add settings for the size of an edge as the optimal
    size may change between analog & digital designs.
* New: In Anabatic:
    - Support for fast position query using a matrix.
    - Computation of the Edge capacity, based on the routing gauge parameters.
    - Graphic display of the edges capacity. Added configuration
      parameters to size the bounding box of an Edge.
* Bug: In Anabatic:
    - GCell::_moveEdges was both too complex (some cases never arise the
      way we divide GCells) and bugged.
