Jean-Paul Chaput a4e46444e2 Various problems in the BLIF parser.
* In CRL Core, in BlifParser, when an input terminal of an instance is
    either connected to power or ground, insert a zero_x0 or one_x0
    Cell to avoid direct connection to the supply (the router is not
    able to do it). The names and terminals of the intermediate cells
    are hard-wired for now (to SxLib).
      When merging Nets, always merge internal nets into external ones
    as the other way around is not always legal.

Jean-Paul Chaput d641f236a3 Suppress warnings when flatening a Cell twice.
* In Hurricane, in Cell::flattenedNets(), if the cell has already been
    flattened, do not issue warnings about duplictated flattened nets.
* In Hurricane, in Net, allow Net::setName() to switch the main name
    for an alias without complaining about an already used name.
* In Cumulus, in RSavePlugin.py, when "views" is supplied in keywords
    (kw) arguments, override the default instead of merging with it.
    This is to allow scripts to save exactly what views they want.

Jean-Paul Chaput 6ad644fac2 New relation for slaved ABs. Do *not* delete blockage nets.
* Change: In Hurricane, in DataBase::CellDepths() the recursion stop
    criterion must be Cell::isLeaf() and not Cell::isTerminal() as
    the second one can be used to hide some levels of hierarchy,
    and we want all of them in a blob.
* New: In Hurricane, in Cell, create a new Slaveds relation to keep
    track of all the Cells with a slaved abutment box. This work is
    incomplete as we do not manage the behavior in case of merge or
    Cell destruction or slaving Cells with aready slaveds ones.
      Modify Cell::setAbutmentBox() to work in both autonomous and
    slaved mode.
* New: In Hurricane, in Net, add a new type of Net: BLOCKAGE this
    avoid us to be dependant on the framework pattern recognition.
    (change propagated to the Python support)
* New: In CRL Core, in the various drivers, recognize blockage nets
    as such and set their type accordingly.
* Change: In CRL, in Toolbox::deleteEmptyNets(), preserve blockage
    Nets. This was the cause of crashs in Kite::BuildPowerRails() as
    we where trying to use a deleted blockage net...
* Bug: In Hurricane, in NetAlias, do not write NetAlias as a name
    but as a type. They were not read back and moreover staying in
    the JSON parser stack.

Jean-Paul Chaput bbab2d14eb Bug, uniquification of unique cells.
* In Hurricane: In Instance::slaveAbutmentBox() and Instance::uniquify()
    use isUnique() instead of isUniquified(). This way we do not clone
    masterCells that are unique in the design. This was the reason
    sometimes "holes" were appearing in the visualiser, as the AB were
    not merged. The uniqification policy may need some refinement.
2016-03-27 17:13:30 +02:00
Jean-Paul Chaput a78882fd5b Clocks in BLIF parser. In RSavePlugin, flags to select views to save.
* Bug: In CRL Core, in BlifParser, recognize clocks (Alliance patterns).
* Change: In Cumulus, in RSavePlugin, "kw" manage a new "views" to
    specify which views must be saved. Physical by default, but sometimes
    we need logical as well. If the design contains uniquified cells,
    save the logical view.
      In ClockTree, abort the clock tree building if the design has no
    top level clock.
* Change: In Katabatic, in GCellTopology, adds 2G_5M1 configuration.
* Bug: Kite, in BuildPowerRails, if we are not in a chip the nets
   composing the H-Tree must be protecteds be blockages.
2016-03-26 11:59:32 +01:00
Jean-Paul Chaput b5d3a2ec3c Update JsonReader for the latest RapidJSON. Doc rebuild.
* Change: In Hurricane, in JsonReader::HurricaneHandler, add RawNumber().
    Don't know what kind of data it parses, so for now if it's called,
    just issue a warning.
* Bug: In documentation, in UsersGuide, add dependencies on doc_HTML and
    doc_LaTeX so they are rebuild if the source files changes.
      Some modifications to work with our new installation of TeXLive 2014.
2016-03-22 15:38:26 +01:00
Jean-Paul Chaput 1ef4bc122f Forgot to catch Bug exception. GCell manage 5 terminals of a Net.
* Bug: In Hurricane, in HApplication, ExceptionWidget ans PyHurricane.h,
    forgot to catch the Hurricane::Bug exception which was leading to
    terminate() without explanations.
* Change: In Katabatic, In GCellTopology, now support one GCell with
    five metal1 terminal of the same net. This unlikely configuration
    did appear in the SNX for the first time...
2016-03-17 16:54:53 +01:00
Jean-Paul Chaput 13c3efdefd In Katabatic, the layer assignment move up part of Net trunks.
* In Katabatic, in AutoSegment::canMoveUp(), adds the ability to reject
    the move up if the density of the depth we comes from is below 0.6
    in all the GCells, activated with the KbChecklowDensity flag.
* In Katabatic, In LayerAssign, new method moveUpNetTrunk2() which,
    unlike the previous one, move up only the part of the Net trunk
    which is connex to the seed segment. Use the canMoveUp with
    low density checking to avoid unbalancing higher metal layers.
* In Kite, in SegmentFsm, use the canMoveUp() with low density checking.

Jean-Paul Chaput da60370b60 Various bugs in the virtual flattening mechanism (part 2).
* Bug: In Hurricane, in Cell_HyperNetRootNetOccurrences::Locator, must
    also check that the current Net is not a DeepNet in the constructor.
    Take the occasion to prune Net that are automatic.
* Change: In Hurricane, in DeepNet::_createRoutingPads(), check for
    already created RoutingPads. That is, the DeepNet must not have
    RoutingPad components or Segments components.
2016-03-15 17:55:48 +01:00
Jean-Paul Chaput b9da9531a7 The VHDL driver must not rename Cell/Instance/Net names.
* Change: In CRL Core, the Alliance VHDL (vst) driver was renaming the
    names of Cells, Instances and Nets into their VHDL conterparts.
    But if we still work on the Cell after saving it, the Net renaming
    will cause touble, especially when there are DeepNets. The name
    of the DeepNet is generated from the Occurrence name with the dot
    separator which is *not* a VHDL valid character for name, thus
    after that the DeepNet name has changed it cannot be reassociated
    with the Occurrence path. This was causing double-flattening issues.
2016-03-14 01:01:21 +01:00
Jean-Paul Chaput 33355f0e54 Various bugs in the virtual flattening mechanism.
* Bug: In Hurricane, in Cell::flattenNets(), addition to the topHyperNets
    vector was done *inside* the components loop, resulting in multiple
    additions of the same top net. This was leading to the RoutingPads
    created multiple times on the same connectors. Hence the conflict in
    KiteEngine::protectRoutingPads().
* Change: In Hurricane, in Cell::flattenNets(), do not create RoutingPads
    or build rings on already routed Nets. A Net is considered already
    routed if it has at least one Segment. This way we avoid Rubbers to
    be drawn over routed Nets.
* Change: In Hurricane, in DeepNet, do not build RoutingPads & rings on
    already routed Nets (same condition as in Cell::flattenNets()).
* New: In Hurricane, in HyperNet, new collection of all component
    occurrences of an HyperNet. May or may not (default) include
    components from the leaf cells.
2016-03-13 19:35:56 +01:00
Jean-Paul Chaput ae0e6aed25 Disable the merged quad-tree feature, no so bright an idea.
* Bug: In Hurricane, In Cell, the quad-tree cannot be mergeds because
    when a geometrical search is performed, components, and even more
    importantly, instances from lower hierarchical levels will be
    reported. And there is no simple way to discriminate them.
* Change: In Hurricane, Cell & Instance, change the flag of
    MergedQuadTree into SlavedAb.
* Bug: In Hurricane, In Instance::slaveAbutmentBox(), the AB of the
    master model must be set before calling setPlacementStatus()
    otherwise the Instance do not get inserted into the quad-tree
    (empty AB).

Jean-Paul Chaput 1dafcbc882 UTurn management in Katabatic & Kite.
* New: in Katabatic, in AutoSegment, recognize segments that are U-turn.
    That is, based on two turn Contacts and going both top or bottom.
* New: In Kite, manage one pitch U-turn by making them diseapear from
    the tracks. And make them same-metal when saving. Add a pack stage
    to try to compact U-turn.

Jean-Paul Chaput b209871ee6 Update copyright to 2016 for Knik, Katabatic & Kite. 2016-03-06 12:36:18 +01:00
Jean-Paul Chaput 12ac23713e Duplicate ScalarSignal creation (signal & global) in VhdlEntity.
* Bug: In CRL Core, in VhdlEntity, when a scalar signal is also global,
    two ScalarSignal where created, but only one can be linked as a
    property on a Net. So when the one *not* linked as a property was
    deleted, an infinite loop started (under Cygwin at least).
      The _globals list now contains pointers to signals that are in
    _signals. The _globals elements no longer needs to be deleted.
2016-03-03 18:14:20 +01:00
Jean-Paul Chaput fce97bb1d9 Corrections in how to access pads terminals in Katabatic/Kite.
* Change: In Katabatic, in GCellTopology::doRp_AccessPad(), if the supporting
    RoutingPad is big (more than two pitch), do not put the access
    contact in the center but on the edge. This is to avoid cut violations
    between the VIAs and the matrix of VIAs that may be generated under the
    RoutingPad itself.
* Change: In Kite, in TrackSegment destructor, if the legnth of the wire,
    without extensions is less than one picth, enlarge it so it encompass
    it's source & target VIAs (to avoid notches).
* Bug: In Kite, in Track destructor, the TrackElements where detacheds,
    but not deleted, causing a memory link.

Jean-Paul Chaput 0f1775a77c Corrected bugs in the print feature.
* Bug: In Hurricane, in CellWidget, do *not* rescale iteratively the _initialSide
    attribute under high DPI (do it once).
* Bug: In Hurricane, in CellPrinter, suppress the divide by 4 scaling of the
    printer widget. Don't remember why I did so, and it generate too small
    pictures.
2016-02-25 14:31:29 +01:00
Jean-Paul Chaput cdacecd32b More destructives iterations over collections correcteds.
* Bug: In Hurricane, in Entity, Instance, Library, Net & Technology, there
    loop over collections while destroying their elements.
2016-02-24 10:44:33 +01:00
Jean-Paul Chaput b57c81dda8 Bug in Cell::_preDestroy().
* Bug: In Hurricane, in Cell::_preDestroy(), the classic mistake again:
    do not iterate over a collection while deleting it's elements.
    Now should be safe.
* Change: In CRL Core, set the default display style to "Alliance.Classic [black]"
    (my favorite).
2016-02-23 17:19:42 +01:00
Jean-Paul Chaput f28daec401 Handling of Cell destruction in CellViewer.
* Change: In bootstrap, in socInstaler.sh, use the current version of
    rapidjson.
* Change: In Hurricane, in FileWriteGzStream, complie to the latest
    rapidjson headers organization.
* New: In Hurricane, in Cell, emit a new signal CellDestroyed toward the
    observers (i.e. the CellViewer(s)), from _preDestroy().
* Change: In Hurricane, in CellViewer, in CellObserver::notify(), manage
    the CellDestroyed case. Do not forget to remove the deleted Cell
    from the viewer's history.

Jean-Paul Chaput a9a0a7d107 Update the socInstaller for the support repositories.
* Change: In bootstrap, in socInstaller.py checkout the support git
    repositories (currently, only rapidjson). Send the report mail
    to <jpc> & <lao>.
* Bug: in VLSISAPD, in the top CMakeLists.txt, do not requires the
    Hurricane cmake, it is build after (cycling dependency).

Jean-Paul Chaput 5baddeb558 Implementation of DataBase native save/restore in JSON (step 2).
* New: In boostrap, in ccb.py, added support for the "support" project
    which contains external dependencies. Currently contains only
    RapidJSON. Those dependencies must be cloned here manually.
* New: In Hurricane, Initializer class for an ordered static initialization
    across different compilation modules.
* Change: In Hurricane, at DataBase level, no longer save the Cells in
    the libraries, but create and ordered list of Cell. Deepest cells
    (leaf cells) first. To avoid dependency problems.
* New: In Hurricane, JSON support for Property.
* New; In CRL, added JSON support for AllianceFramework, Environement &
    Catalog and their associated properties. Adjustment of the
    AllianceLibrary creation policy.
2016-01-21 00:25:39 +01:00
Jean-Paul Chaput f537a10d45 Implementation of DataBase native save/restore in JSON (step 1).
* New: In Hurricane, added first support for DataBase native import/export
    using JSON.
      We choose RapidJSON, in SAX mode, to manage the JSON format low level
    Read/Write. Thus, it's Git repository http://github.com/miloyip/rapidjson
    must be added under ~/coriolis-2.x/src and manually build and installed
    in the Coriolis installation tree (to be integrated in ccb later).
      Two mode are being supported:
        1. Cell mode: one Cell only is saved. In that mode, Entities
           referred by Occurrences are "outside" the file. They are coded
           through their "signature" (mostly, all the values of their
           attributes). The ids saved in the file cannot be restored
           identically as we cannot predict when and in which context the
           Cell will be reloaded.
        2. Design Blob mode: the whole design hierarchy, down and including
           the standard cells is saved. This way the design is completly
           self contained and Entities ared referred through their ids.
           A design blob can only be loaded immediatly after starting cgt
           as the DataBase *must* be empty. This way we restore the whole
           design hierarchy with *exactly* the same ids.
      Now, Hurricane object should provide a "toJson()" method for driving
    JSON, and be associated with a JsonObject derived class for parsing.
* New: In Hurricane, ability to force the next id that will be used for a
    DBo (used by Design Blob Mode).
* New: In Hurricane, in DataBase, added getCell() and getLibrary() functions
    to allow the hierarchical access of a Cell/Library in native mode
    (i.e. whithout the requirement of AllianceFramework).
* New: In Hurricane, In CellViewer, added menu entry for Save/Load of
    JSON Design Blobs. Added at this level because we consider it as the
    "native" format of Hurricane.
* New: In Unicorn, added support of import/export of JSON Cell.
* Bug: In Hurricane, in Instance, when cloning an Instance or uniquifying
    it's master Cell, we forgot about the Occurrences (through shared pathes).
    When an instance is cloned the Shared pathes still points toward the
    original Instance. And when it's the master Cell that is uniquifyed
    it's the Entities pointed to that remains in the original Cell.
    This is a software design problem. It is difficult to define what
    policy to adopt when uniquifying: basically that means that one
    Occurence is either moved onto the clone or duplicated. Furthermore,
    it is not trivial to known what Occurrence is pointing on the
    uniquifyed/cloned item. Have to think about it a little more.
* Bug: In Etesian, in EtesianEngine, build the flattened nets and their
    RoutingPads *after* uniquifying (through slaving bounding boxes).
    This way we avoid the Occurrences problem described above.
* Bug: In Etesian, in EtesianEngine, invalidate the RoutingPad after
    processing the placement so they are put into the right quadtree.
    This problem is due to the fact that the RoutingPads do not belong
    to the Instance that they refer. And when this instance is moved
    around, she doesn't inform the RoutingPad that is has moved.
    More software architecture design to review...

Jean-Paul Chaput 1adefabb2f Correctly remove VHDL Entity and Bit properties.
* Bug: In CRL Core, in Vst driver, remove VhdlEntity (from Cell) and
    BitProperty/Bit (from Net) with the property remove and not the
    destroy() method. The BitProperty removal was completly forgotten
    leading to the use of removed Signals when doing multiple saves
    (hence core-dump).
* Change: In CRL Core, in Vst driver, never save as Signals the DeepNets
    as they are created by a virtual flatten and do not connect any
    instances at top level. Note that they will exists in the physical
    file if routing layout has been created.

Jean-Paul Chaput 9db97608cb More clever way of taking into account constraints on caged terminals.
* Change: In vlsispad, in Dots, add an enable/disable flag because when printing
    into a cmess, it is only the base class ostream which is took into account
    as none of it's methods are virtuals (silly me).
* Bug: In Etesian, print into cmess instead of cout and make use of the Dots
    enabling feature.
* New: In Katabatic, added AutoContact::migrateConstraintBox() to transfert
    constraint from one contact to another.
      New flag for AutoContact, CntWeakTerminal for AutoContact which are at
    the other of a segment directly connected to a terminal. They may hold
    special constraints in case of caged terminals (computed in Kite).
      In AutoHorizontal & AutoVertical, in ::_makeDogleg(), transfert flags
    and constraints when breaking a segment directly connected to a terminal.
* New: In Kite, in protectCagedTerminals(), uses cross constraint on the
    AutoContact opposite to the ContactTerminal (CntWeakTerminal) instead
    of moving up one terminal over two consecutives. This is simpler without
    degrading the routing quality.

Jean-Paul Chaput ed557d9027 Added support for "same layer" dogleg. Big fix for pad routing.
* Change: In Knik, in Vertex, add a "blocked" flag to signal disabled
    vertexes in the grid (must not be used by the global router).
      Modificate the Graph::getVertex() method so that when a vertex
    is geometrically queried, if is a blocked one, return a non-blocked
    neighbor. This mechanism is introduced to, at last, prevent the
    global router to go *under* the pad in case of a commplete chip.
* New: In Katabatic, in AutoSegment, a new state has been added: "reduced".
    A reduced segment is in the same layer as it's perpandiculars.
    To be reduced, a segments has to be connected on source & target to
    AutoContactTurn, both of the perpandiculars must be of the same layer
    (below or above) and it's length must not exceed one pitch in the
    perpandicular direction.
      To reduce an AutoSegment, call ::reduce() and to revert the state,
    call ::raise(). Two associated predicates are associated:
    ::canReduce() and ::mustRaise().
      Note: No two adjacent segments can be reduced at the same time.
* Bug: In Katabatic, in GCellTopology, add a new method ::doRp_AccessPad()
    to connect to the pads. Create wiring, fixed and non managed by
    Katabatic, to connect the pad connector layer to the lowest routing
    layers (depth 1 & 2). The former implementation was sometimes leading
    to gaps (sheared contact) that *must not* occurs during the building
    stage.
      Remark: This bug did put under the light the fact that the initial
    wiring must be created without gaps. Gaps are closed by making doglegs
    on contacts. But this mechanism could only work when the database if
    fully initialised (the cache is up to date). Otherwise various problems
    arise, in the canonization process for example.
* New: In Katabatic, in AutoContactTerminal::getNativeConstraintBox(),
    when anchored on a RoutingPad, now take account the potential rotation
    of the Path's transformation. Here again, for the chip's pads.
* New: In Kite, support for reduced AutoSegment. TrackSegment associateds
    to reduced AutoSegment are *not* inserted into track to become
    effectively invisibles. When a segment becomes reduced, a TrackEvent
    is generated to remove it. Conversely when it is raised a RoutingEvent
    is created/rescheduled to insert it. All this is mostly managed inside
    the Session::revalidate() method.
* New: In Kite, in KiteEngine::createGlobalGraph(), in case of a chip,
    mark all global routing vertexes (Knik) that are under a pad, as blockeds.
* Bug: In Cumulus, in PadsCorona.Side.getAxis(), inversion between X and
    Y coordinate of the chip size. Did not show until a non-square chip
    was routed (i.e. our MIPS R3000).
* Change: In Stratus1, in st_placement.py add the ClockBuffer class for
    backward compatibility with the MIPS32 bench. Have to review this
    functionnality coming from the deprecated placeAndroute.py.
      In st_instance.py, no longer creates the Plug ring of a Net.
    In my opinion it just clutter the display until the P&R is called.
    Can re-enable later as an option (in Unicorn).
* Change: In Unicorn, in cgt.py, more reliable way of loading then running
    user supplied scripts. Borrowed from alliance-checker-toolkit doChip.py	.

Gabriel Gouvine d71ba37aa7 Changed Coloquinte's datastructures naming
Used a big sed command
Needs some testing
2015-07-27 15:36:50 +02:00
Jean-Paul Chaput 8ead28d86c In the Netlist tab of the Controller, add a count of RoutingPads.
* New: In Hurricane, in NetlistWidget & NetlistModel, adds a column for
    the RoutingPads count. Special display to mark global nets.
* Change: In Hurricane, in all MVC's models, some improvements on the
    way the columns are sized and the titles displayeds.
2015-07-25 11:55:42 +02:00
Jean-Paul Chaput ed2cd18c48 Too narrow search area for straight net in Knik.
* Bug: In Knik, in Graph::Dijsktra(), when all the RoutingPads of a net
    are aligned, the seaching area is only one vertex wide (in width or
    height). That is, it contains only one edge in it's main direction.
    So when that sub-graph contains a fully blocked edge, Dijkstra cannot
    find a path... Now enlarge the one edge graph to at least three by
    inflating the search area. Curiously a code for similar purpose seems
    to be present, but commented.
2015-07-25 11:38:00 +02:00
Jean-Paul Chaput ff69a2ef74 Added Hierarchy browser to the Controller.
* New: In Hurricane, added hierarchy browser in the controller.
    The hierarchy is presented as a tree. New MVC, HierarchyInformations,
    HierarchyModel and HierarchyBrowser.
      When using a data model which is not directly connect inside the
    model, we must use the internalPointer field of the QModelIndex.
    But this field is also used by the QSortFilterproxymodel, this
    prevent using it with a Tree model.
      The filter is directly implemented and is specific to each
    Instance entry.
* Change: In CellWidget & CellWidget::State, now store the Cell and
    a Path, this way we can keep track of the hierarchy when browsing.
    The Path is in the State and so propagated back to the Controller.
* Change: In HierarchyCommand, use the Path with setCell().

Gabriel Gouvine 98d4dd4fdf New useful function to merge bounding boxes 2015-07-02 17:31:21 +02:00
Jean-Paul Chaput ae6eeb8f56 Merged QuadTrees in overlayed Cells (placed together).
* New: In Hurricane, in Cell & Instance, add the ability to merge the
    QuadTree when *second level* instances of a Cell are placed in
    the same space as the top Cell. This is the case of a deeply
    hierarchical design made of only standard cells that are to
    be placed in a "flat" manner.
      The design is uniquified then the intermediate instances models,
    which should be unique at that point have their QuadTree merged
    through a call to Instance::slaveAbutmentBox(). That method will
    make the model of the instance use the QuadTree of the Cell to
    which the instance belong. The instance model no longer posseses
    a dedicated QuadTree. As a corollary the abutment box of both
    Cell are kept identical and the Instance has it's transformation
    set to (0,0,ID).
      Remark: when we talk about "QuadTree", we mean in fact the
    QuadTree for the instances *and* the SliceMap (Layer+QuadTree).
      Consequence in Query: when going through the resulting
    "flattened" QuadTree we will find objects with an incomplete
    Path du to the fact that we didn't have to explore their
    Instance/Cell level to reach them. The shunted part of the
    Path is stored in the Go master Cell in the _shuntedPath
    attribute. This also affect the displayed depth of hierarchy,
    but not too badly.
* New: In Hurricane, in Cell, new methods:
    - Cell::updatePlacedFlag() : set the placement flags.
    - Cell::isUnique() : one or less instance.
    - Cell::isUniquified() : is the result of an uniquification.
    - Cell::isUniquifyMaster() : is the reference cell of the
    uniquification.
* Change: In Hurricane, in Cell::Uniquify(), uniquify a Cell only
    if it is unplaced. We do not need to duplicate placed Cells
    (see datapathes).
2015-06-26 18:35:11 +02:00
Jean-Paul Chaput 61f2b8630f More resilient KiteEngine::wipeoutRouting(). Added to graphic menus.
* Change: In KiteEngine::wipeoutRouting(), remove only the Contacts
    that are *not* anchored. Any other will be indirectly destroyed.
* New: In GraphicKiteEngine, add an encapsulation and a menu for
    wipeoutRouting().
