Jean-Paul Chaput 41c9959e30 Added support for diagonal wires (45° and 135°)
* New: In Hurricane::Diagonal, new object to represent 45° and 135°
    segments (X routing). Althought they have source & target, they
    are not articulated like Horizontal & Vertical, due to the
    combined displacement of X and Y (diagonal).
      Maybe we should create a common class for all the polygons
    to make "::getContour()" a method.
      Now we could represent self capacitances and high frequency
    wires.

Jean-Paul Chaput 0902b21f23 Added support for huge approximated polygons (for photonics).
* New: Hurricane::Triange as been renamed into Hurricane::Polygon.
    Add support for convex polygons. Polygon are approximateds by
    excess by a manhattan rectilinear polygon (with potentially
    thousands of vertexes). To reduce the memory footprint,
    compaction techniques reducing by at least a factor 4 has been
    implemented. We could go further by only storing the non-repetitive
    part of the edge (defined by the integral fraction dY/dY).
    We will see, if the program slows too much.
      The manhattan approximate is always computed but displayed
    only if the polygon grid step is greated than 4 pixels.
      The level of approximation of the polygons can be controlled
    through the "DbU::_polygonStep" parameter.
* Change: In CRL/coriolisInit.py and CRL/helpers/Technology.py, regroup
    all DbU related parameters into "technoConfig" (i.e. suppress
    "viewerConfig"). Update all the relevant technology.conf configuration
    files.
      Change the loader behavior so that "technoConfig" is read first
    and is now responsible for creating the Technology of the DataBase.
* New: In Hurricane::CellWidget, added support for displaying mahanttanized
    polygons.
* Change: In documenation/scripts/expample/polygons.py, perform (I hope)
    a comprehensive test of the polygons (check all slopes, clockwise and
    conter-clockwise).
* New: In Hurricane::DbU, added template to manage vector<> of DbU.
    Support for the "polygonStep" parameter.

Jean-Paul Chaput dd4a01fe70 Validating channel routing mode (two metals) on SNX.
* New: In Hurricane::Entity, add an id counter limit and a memory size
    limit. The two limits are checked only when a new Entity object is
    created. This should help avoiding massive memory links.
* New: In CRL Core, add a "crlcore.groundName" and a "crlcore.powerName"
    parameter to specify the name of the ground/power signals to be
    created if they are missing in a Cell. For Alliance libraries it
    would be "vss" & "vdd" (default values), but for real technologies,
    it is often "gnd!" & "vdd!".
      The Blif parser is modificated to make use of it.
* Bug: In AnabaticEngine::unify(), set the resulting unified segment in
    the  center of the GCells common side. Gcells under a segment are
    found by using the edge that cover the segment axis. When we have
    a "bend" GCell stack and the axis is wrong, they could be ommited.
      This was causing deleted segments to be not removed from some
    Edges, then core dump.
* Change: In Anabatic::AutoSegment::create(), smarter choosing of the
    reference contact, select the fixed or terminal one instead of
    always the source one.
* New: In Anabatic::Edge::isEnding(), new function to check if a
    segment going through an Edge is starting/ending in either source
    or target GCell of the edge (active only when running in channel
    mode).
* New: In Anabatic::Edge::add(), a segment takes part in the occupancy
    only if it is not ending in either source or target (channel mode
    only). The occupancy due to terminal is pre-computed in Katana.
* New: In Anabatic::Edge::ripup(), in channel mode, never ripup a
    segment which is ending in either source or target (we *have* to
    access this edge to connect to the terminal).
* Bug: In Anabatic::GCell::hcut() and vcut(), force the update of
    the Edge which is on the side that will get splitted by the cut.
    It's capacity will be reduced to it must be updated.
* Change: In Anabatic::GCell::updateGContacts() add a flag to conditionnally
    update horizontals or verticals only. We may require only a partial
    update when resizing the GCell in only one direction.
      This, again, related to the fact that we compute the GCells under
    a segment thanks to it's axis position, so we need to be very careful
    when modificating axis.
* Change: In Katana::Block::resizeChannels(), only update GContact vertical
    position. Do not disturb X positions of segments.
* Bug: In Katana::GlobalRoute::DigitalDistance, in channel mode, some
    Edges can have a zero capacity, but still be reachable if the net has
    a terminal in either source or target. Look for this case and return
    a distance of zero instead of "unreachable". This was causing the
    global routing not to complete in channel mode.
      For computing the edge distance, makes the vertical edges much more
    long (10 times) than the horizontal ones as the vertical capacity is
    very limited. Hard coded for now, should make it a parameter in the
    future.
* Change: In KatanaEngine::annotateGlobalGraph(), decrease the capacity
    of edges with reserveCapacity for each terminal inside a GCell.
    Both north and south edges are decreased as we a terminal will
    block both north and south edges.
      As a counterpart, the Edge capacity is not decreased when the
    global router connect to a terminal.
* Change: In Katana::RoutingEvent::revalidate(), when in repair stage,
    do not expand the slack for horizontal segments in channel mode.
    So they may not overlap the standard cell row.
* Bug: In Stratus documentation, do not use the french option in babel,
    the documentation is in english!
* New: In Documentation, added Hurricane/Python tutorial, part for drawing
    layout.

Jean-Paul Chaput 95d1b53646 Complete hoverhaul of the documentation to Sphinx.
* New: In documentation, reorganise all the various documents into one
    Sphinx coherent one. The index also provide a link toward the
    Doxygen generated doc (C++ APIs) and the venerable LaTeX2HTML ones
    (for Stratus).
      This will make easier all future extensions to the doc corpus.
      The generated documentation is commited into Git so a new user
    can use it directly after cloning the repository.
      The HTML doc is truly generated by Sphinx, but the pdf one is
    created rst2latex. The Sphinx pdf writer is buggy when a "tabular"
    contain a multicol and a multirow in the same area of the table.
    rst2latex handles it correctly.
      We use a theme borrowed for Read The Doc (half of it).
      It seems that some Javascripts are not working correctly,
    namely the folding of the navigation sub-menus and the index
    generation and search mode.

Jean-Paul Chaput c44c6b13f3 Adjust Katana event sort. CMake detection of Python 2.7 only.
* Change: In all top CMakeLists.txt, force the use of Python 2.7 as
    we do not compile against 3.x flavors. Do not use the "EXACT"
    flags as it will not recognize 2.7.x versions.
* Change: In Katana::RoutingEvent::Key::Compare(), preliminary
    experiments shows that the best sorting order is:
      - Lower layer first (i.e. M2 -> M3 -> M4 -> ... )
      - Longer segments first.
      The later seems to be counter-intuitive. Guess is that placing
    the small ones first generate a more important fragmentation of
    the big ones. They are placed too early and are difficult to move
    afterwards.
      Another feature to test is *not* inserting pushed left/right
    segments if they are not *already* routed.
* Change: In PyKatanaEngine.runNegociate() now takes a flag argument,
    provided through the new PyKatanaFlags exported object.
    (doChip.py must be changed accordingly)

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.

Jean-Paul Chaput 4842f21a2e Update to Qt 5, requires cmake 2.8.9. New placer: Etesian.
Update to Qt 5:
* Change: Now requires at least cmake 2.8.9.
* Change: CMakeLists.txt needs small changes. Qt modules must be found
    one by one (Core, Gui, Widgets). Must add "set(CMAKE_AUTOMOC ON)"
    in the top file and replace "qt4" prefix in macros by "qt5".
    Added simpler macro "setup_qt()" in FindBootstrap.cmake.
* Change: No longer need to include <QGtkStyle> is is choosen by default
    according to the current desktop environment.
* Change: In <hurricane>, In HApplication, launch ExceptionWidget when
    a std::exception is catched instead of silently discarting it.

New placer Tool: Etesian
* New: <etesian> analytical placer. Encapsulate Coloquinte from
   Gabriel Gouvine.
* New: in <documentation>, add stub demonstration ToolEngine <smurf>.
   Needs to be commented.

Miscellaneous:
* New: in <boostrap> and <unicorn>, added support for Etesian, the new
    analytic placer. The tool itself will be added in the next commit.
* Bug: in <CellWidget>, when shifting the display buffer, we no longer
    can copy the buffer on itself (we should never have). Now go through
    a temporary one (PlaneId::AutoCopy) which is added to the
    DrawingPlanes. Affect "goLeft()" and "goUp()".
* Bug: In <CellWidget>, remove the WA_PaintOnScreen flag/attribute.
    When it's on, no PaintEvent is transmitted to the CellWidget
    when it's the central widget of the <CellViewer> (QMainWindow).
    It's something I still don't understand from the doc of Qt.
* Change: In <AreaCommand>, use the PlaneId enumeration instead of a
    anonymous numerical index.
* Change: In <HApplication>, no longer catch and silently discard
    standartd exceptions but launch the ExceptionWidget...
    Suppress the now deprecated constructor with "Type" argument.
* Change: In <SelectionModel>, the "reset()" method is deprecated in
    Qt5, instead enclose the "clear()" by a "beginResetModel()" and
    "endResetModel()" pair.
* New: In <crlcore>, add support for ISPD05 benchmarks (in Bookshelf
    format). Forked from ISPD04 and not finished yet.
* Change: In <Mauka>, distinguish the Action string identifier from
    <Etesian>
* New: In <unicorn>, add entry for ISPD05 loader. Add entry for
    <Etesian> analytic placer.

Jean-Paul Chaput 14a5f5f7ef Documentation restructuration
Documentation restructuration:
* Bug: in <hurricane>: bad figure for transf-R1.
* Change, in <kite>: Remove deprecated configuration variables.
* New: documentation <tool> to regroup all documentation not directly
  related to one tool.
* Change, in <crlcore>, move the user's guide and the top doc index
  into <documentation>.
* New, in <documenation>: added Python script demo based on AM2901.
