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

EricLaoGitHub 5f25ba349f * Change: Dijkstra, GCell
Restriction on vertex are now correctly done.

* Change: Constants
  There is only one type of Strut.

* New: LoadGlobalRouting
  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.
    This solve better the routing of the control part of the register file.
    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.

Jean-Paul Chaput 5435ca1933 Added missing UpdateSession in Stratus & Plugins.
* Bug: In Cumulus & Stratus, now that creation of Hurricane objects must be
    enclosed in UpdateSession, has to adds them into Python code.
* Bug: In Anabatic & Katana, in the global routing stage suspend the timed
    bewteen ripup steps instead of resetting it.

Jean-Paul Chaput ce00b37cbf Enable the display of GCells as a density map (and not boundaries).
* Bug: In Anabatic::RawGCellsUnder, *again*, the north and east borders
    of the whole area *are* includeds (shut up disgraceful warning).
* New: In Anabatic::GCell, add a display mode to select between boundary
    display (for analogic) and density display (for numeric).
* Bug: In KatanaEngine::runGlobalRouter(), do not check if an Edge cannot
    be desatured when the vector or overloaded Edges is empty.
    (one less disgraceful warning)
* New: In GraphicKatanaEngine::drawGCell(), support for drawing the GCells
    in density mode. Use the fire scale and the MaxDensity mode.
      Setup the GCell drawing mode in GraphicKatanaEngine::initGCell().
* Change: In GraphicKatanaEngine::drawEdge(), adjust the various thresholds
    for showing the Edge and its label.
* New: In CRL Core, adds "anabatic.gcell.displayMode" to the set of Anabatic
    parameters.
      Adjust the showing threshold for GCells in "display.conf" so when the
    zoom level is low, we still can see the density map.

Jean-Paul Chaput 8376d0c209 Remove GraphicAnabaticengine, temporarily made for debugging.
* Change: In Anabatic, remove GraphicAnabaticEngine, PyGraphicAnabaticEngine,
    PyAnabaticEngine (but keep PyAnabatic for constants exportation)
    and GlobalRoute (moved to Katana). Drawing methods for Edge & GCell
    are moved into GraphicKatanaEngine.

Jean-Paul Chaput 92522fef0b Solved more problems related to GCell not owning north/east boundary.
* Bug: In Anabatic, in AutoHorizontal & AutoVertical, native constraints
    must use GCell::getConstraintsUMax().
* Bug: In Anabatic::GCell, correct terribly bad implementation of
    both getConstraintUmax().
      In getSide(), use getConstraintUMax().
* Bug: In Anabatic::AutoContact, setCBUMax() must be set using the GCell
    getContraintUMax().

Jean-Paul Chaput ebc4a0cdbf Complete Python support.
* New: In PyAnabatic, export the various Engine constants.
* Change: In Katana, in TrackElement and derived classes, add a getSegment()
    method for easier access to the underlying Hurricane segment.
* New: In PyKatanaEngine, export the loadGlobalRouting method which was
    missing (for use by Unicorn/cgt).

Jean-Paul Chaput c5f60dc3d8 Correct multiple backtrack from same connex components (pathological).
* Bug: In Dijkstra::_materialize(), in some special case a connex component
    can is reached by two (or more) vertexes. But of course it will be
    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.
    So stop any backtrack when the first neighbor of a starting point
    has it's connex id *not* set.
2016-08-27 16:00:14 +02:00
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
    Anabatic::AutoContactTerminal forgot to call the _preCreate() function
    in the various create().
* Bug: In Matrix::getUnder(), if on the N/E boundary, decrease by one to
    be enclosed in it.

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-).

* Bug: In Anabatic::GCell, when width and/or heigh is null, do not try to
    compute densities as it will trigger a divide by zero (and do not make
    much sense anyway).
* Change: In CRL Core, in cmos/alliance.conf, honor the ALLIANCE_TOP variable
    if it is found in the user's environement.

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()).
      And fused back into one if a branch is removed (unify()).

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.

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.

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 fac3474d55 Anabatic transient commit 4.
* Bug: In Anabatic:
    - In Edge, materialize was done before the Edge get it's final position.
      Must be invalidated afterwards for the UpdateSession to put him in
      the correct QuadTree.
    - Functional (debugged) Dijkstra skeleton.

Jean-Paul Chaput 1f4d6b7e83 Anabatic transient commit 4.
* New: In Anabatic:
    - A Dijkstra skeleton, not debugged yet.

Jean-Paul Chaput 6ef5819310 In getCapacity(), check for empty intervals. 2016-05-26 18:54:57 +02:00
Jean-Paul Chaput d7bd8a4bf4 Anabatic transient commit 3.
* New: In Anabatic:
    - AnabaticEngine now have a valid destructor and a "reset()" method.

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.

Jean-Paul Chaput 61e9abddbd Anabatic transient commit 1.
* New: In Anabatic, basic support for GCell/Edge creation.
