Jean-Paul Chaput 8328c890bb In Stratus, in dpgen_RAM get cell height from the library.
* Change: In Stratus, in dpgen_RAM, the cell height was fixed to 50l.
    Now read the prech[0] to set up the cell height (useful for MOSIS
    cells).
* New: In Stratus, in buildModel(), the stand alone generator caller
    now support a className, a modelName and a set of parameters to
    pass on to the model. This is very useful when the module name
    (the file), the class name and the model name are not the same.

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	.

Jean-Paul Chaput bd3984a313 Correctly manage clock net isolateds from the main clock.
* New: In Bootstrap, in ccb.py, check if cmake is installed and issue
    a warning, if not.
* New: In Hurricane, added Cell::getDeepNet() to search for a deepnet
    given a path and a leaf net. This method is slow and must not be
    used too often. Introduced for Kite::BuildPowerRails().
* Change: In CRL Core, in cmos/alliance.conf, modify the clock name
    pattern to match the sub-clock signals in the datapath operators.
* Bug: In Etesian, do not blindly reset the top cell abutment-box.
    Do it only if it's empty, otherwise keep it.
* Bug: In Kite, in buildPowerRails(), in getRootNet() the management
    of clock nets was incomplete. The case of unrouted clock nets
    that where not connected to the top core clock net, like the
    one in the datapath registers was faulty. They were partly
    recognized as unrouteds and partly as blockage generating a
    routing deadlock: routage impossible due to blockage generated
    from itself...
* New: In Stratus1, add a buildModel() utility function to automate
    the model generation and allow a call by the model name (string).
* Change: In Unicorn, in cgt.py, display the Alliance environement.

Jean-Paul Chaput 7296dcd6fb Make the Python interface closely mirroring the C++ one.
* Change: In Isobar, the Python interface was not exactly mirroring the
    C++ one, now it is the case. The Python code should look likes almost
    exactly like the C++ one, the only differences remaining being due
    to the languages respective syntaxes. Note that in the case of
    constructor functions, it leads to a slightly longer notation in
    Python that it could have been (mimic the ".create()" static
    member). Main modifications:
    1. Mirror the static constructor syntax with create():
          Cell( ... )   ==>  Cell.create( ... )
    2. Correct hierarchy for constants in Instance, Net, Pin
       & Transformation. For example:
          Hurricane.PlacementStatusFIXED
                     ==> Hurricane.Instance.PlacementStatus.FIXED
          Hurricane.OrientationID
                     ==> Hurricane.Transformation.Orientation.ID
          Hurricane.TypeLOGICAL  ==>  Hurricane.Net.Type.LOGICAL
          Hurricane.DirectionIN  ==>  Hurricane.Net.Direction.IN
* Change: In CRL Core, correction to match the improved Python API
    in the configutation helpers.
* Change: In Cumulus, correction to match the improved Python API.
* Change: In Stratus, correction to match the improved Python API.
* Change: In Documenation, update for the new Python interface
    (both user's guide & examples).
* Note: We must port those changes into Chams for it to continue
   to run.
* Change: In Documenation, update the Python script support part.

        for putting true stop points. The Breakpoint() method calls the
        View() method. Will simplificate my explanations to the students...

Jean-Paul Chaput e736739eef * All Main Python Modules:
- Change: New problem identified with the Python modules: each module seems
        to be built as a complete binary, so all the static C++ initializers are
        allocated in each module. In particular the C++ tree inheritance is built
        for *each* module so we cannot longer uses the typeid() comparisons
        across modules... It was used by boost::program_options to perform is
        casts with boost::any and was starting throwing exceptions because of
        bad casts. program_option was first initialized in "configuration"
        first included by PyViewer then in PyCRL (see Utilities.cpp).
          A first solution is to re-order the import of Python modules in
        stratus1/st_model so that CRL is imported first.
          The second is to not not link "configuration" with boost::program_option
        as only the binary vlsisapd-conf-editor needs it.
          That is a serious problem of which we must be aware and can cause further
        strange behaviors.
          Debug code used to diagnostic has been kept commented in the sources a
        it may be needed again :-(
          This behavior do not affect our singletons because they are part of
        dynamic libraries that seems to be correctly shared between the various
        Python modules.

  * ./stratus1,

    - Change: Replace calls to CRL.getAllianceFramework() by CRL.AllianceFramework.get().
