Jean-Paul Chaput c70a220016 Correct some old style Hurricane/Python constants in Stratus. 2016-11-10 10:34:34 +01:00
EricLaoGitHub 9d63612661 Debug correction:
* Bug: Indentation adjusted for debug print.

Jean-Paul Chaput dc46340d6a Redesigning access to analog terminals in devices.
* New: In Anabatic::AutoContact, added forceOnGrid() method to allow
    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.

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.
2016-10-04 17:12:58 +02:00
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.

    if we cast into (void*).

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.
2016-09-11 13:20:05 +02:00
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 d8fc626678 Attempt to close all UpdateSession after catching an exception.
* New: In Hurricane::UpdateSession, added "reset()" static function to
   close all the currently opened sessions.
* New: In Hurricane::ExceptionWidget::catchAllwrapper(), close all
    pending UpdateSession if the user choose to resume.
2016-09-10 11:13:52 +02:00
Jean-Paul Chaput 6562792e53 Delay materialization of new objects until the UpdateSession::close().
* Change: In Hurricane::Go, instead of immediatly materializing a newly
    created Go (inserting it in a QuadTree) delay it until the closing
    of the UpdateSession. We call "invalidate()" in "_postCreate()"
    instead of "materialize()". This way, the abutment box of Gos is
    taken into account only when the session is closed. There was a
    problem when the abutment box was changing after the object creation
    misleading the algorithm of the QuadTree. This was occuring only
    when an object was created, not modificated, because in the later case
    the Session mechanism was used. Now, the Session mechanism is used
    in all cases.
      As a side effect, it will speed up the parser by making all QuadTree
    insertions in one step.
* Change: In Hurricane::JsonCell, forgot to call Cell::materialize() when
    the Cell is completed (as was done in ordinary parsers). The call is
    made in the destructor of the JsonCell.
* Change: In Hurricane::Cell, add QuadTree in the inspector support.
2016-09-08 21:50:17 +02:00
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.
2016-09-07 11:21:36 +02:00
Jean-Paul Chaput 061480dbd9 No longer systematically generate a digital grid when Katana is created.
* Change: In Katana, rename "_initDatabase()" into "digitalInit()", and
    explicitly calls it only when we are certain to work on a digital
    design.
2016-09-06 16:27:20 +02:00
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 0a488d16af Add not managed yet configuration 2G+1Pin M2 in GCellTopology.

    2G+1Pin M2.
2016-08-27 16:01:05 +02:00
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-).

Jean-Paul Chaput f7e981a840 Fix bug & compatibility issues with Qt 5.
* Bug: In Hurricane, in NetlistWidget CTOR, the horizontal header was set
    up assuing that there was (at least) three sections (column) in the
    model, which was wrong. Now it is done in the setCell() method which
    know the exact number of sections.
      It was a bug in both Qt 4 & 5, but was showing only under Qt 5.

Jean-Paul Chaput 675e20867b In Backtrace, prevent looping when an error occur inside itself.
* Bug: In Hurricane, in Backtrace, under RHEL 6 when the package
    <devtoolset-2-binutils-devel> is *not* installed, Backtrace uses the
    wrong "bfd.h" from the system instead of the one from the devtoolset2,
    causing itself to core.
      The Backtrace, then try to create a second Backtrace from this
    error, generating an infinite loop. To prevent this situation add a
    counter so that only one Backtrace can be created at a any time.
    And incidentally display a more meaningful error message along with

* 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).

Jean-Paul Chaput 3835d6f7ad Diplay function, file & line number in the backtrace (like gdb).
* New: In Bootstrap, add cmake detection for libbfd.
* New: In Hurricane, in Backtrace, add BFD support to read debuginfo from
    the shared libraries (aka DSO) when compiled with "-g". This avoid the
    tedious step of running gdb after generating a core dump. It is also
    mandatory in ExceptioWidget to known from where an exception was thrown
    as Qt::notify() block all C++ exceptions.
      Currently works only under Linux (gcc or clang), may be extended in
    the future.
      The BFD reading is based on the small utility from:
          Don Hatch (hatch@plunk.org)
          http://www.plunk.org/~hatch/goodies/backtracefilt.C
      And small trinket: adjust the size of the window for high DPI screens.

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).

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()).
