Jean-Paul Chaput 767407736d Add a fully generated documentation in the git repository.
* Change: In all tools supplying documentation, as we use some specific
    software to create the doc, they may not be available, or worse, be
    and incompatible version. So, by default, we install the files shipped
    with the git repository. To force a full doc rebuild, use the "--doc"
    flag of ccb.py.

Jean-Paul Chaput 4f089ffdea Polygon internal normalization. Sub-polygons for GDSII driver.
* Change: In Hurricane::Polygon, store the points so they are always
    ordered in the counter-clockwise (trigonometric) direction. This
    simplicificate internal computations.
* New: In Hurricane::Polygon, added getSubPolygons() methods, that
    split horizontally the polygon in sub-polygons of about 1000
    vertexes. This is mainly to be used by the GDSII driver to abide
    to the XY 4000 points limitation.
* New: In Hurricane::Isobar, export support for Point collections so
    the various contour Polygon methods can be created in the Python
    interface.
* New: In CRL::GdsDriver, split the Polygons into set of sub-polygons
    of less than 1000 vertexes. Use the getSubPolygons() method.
* Change: In stratus1.dpgen_RF2, makes more explicit error messages
    about placement by displaying the faulty vs. expected coordinates.

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 2b9c929f80 Compliance with cmake 3.0 (Debian 9.2). Corrects all warnings. 2017-12-02 14:30:05 +01:00
Jean-Paul Chaput de02cf5685 In stratus.buildModel(), do not always save Logical AND Physical.
* Bug: In stratus.buildModel(), the physical view was always saved, even
    only the logical one was created. Also add the ability to run the
    simulator.
2017-10-30 15:41:26 +01:00
Jean-Paul Chaput 0498ade143 In stratus.py, buildModel was always saving logical & physical. 2017-10-27 10:12:23 +02:00
Jean-Paul Chaput c339e5c9e3 Check for any version of Python 2, instead of 2.7. 2017-07-11 17:52:58 +02:00
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)
2017-05-11 17:26:56 +02:00
Jean-Paul Chaput b2e955185b Default stratus1.mappingName was not set correctly.
* Bug: In CRL.python.coriolisInit(), when it's not set, the stratus1.mappingName
    configuration variable is equal to "" and *not* "not_set".
* Bug: In Etesian::EtesianEngine::toColoquinte(), followup of the previous
    bug, bad FIXED/PLACED test when the AB is set.

Jean-Paul Chaput 3758bd098e attachPlugOrPin() do not core-dump when there is 0 plugs+pins.
* Bug: In CRL::ToolBox::attachPlugOrPin(), simply returns when there is
    no plugs/pins to connect instead of doing an assert().
* Change: In Hurricane, more informative trace information for Python
    ProxyProperty managment.
* Bug: In Stratus, when merging nets with the "<=" operator some table
    of lookup of Hurricane Net are not updated correctly. As I don't
    understand well enough the Stratus code **is is not corrected**.

Jean-Paul Chaput (acting Coriolis) 3ef5ced601 Merge branch 'devel_anabatic' of file:///users/largo2/git/coriolis into devel_anabatic 2016-11-10 10:37:57 +01:00
Jean-Paul Chaput (acting Coriolis) 2dadce1957 Forgotten UpdateSession calls in Stratus. 2016-11-10 10:37:23 +01:00
Jean-Paul Chaput c70a220016 Correct some old style Hurricane/Python constants in Stratus. 2016-11-10 10:34:34 +01:00
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 8fc4056a7a Make RF1 support different slice height. 2016-04-24 16:27:38 +02:00
Jean-Paul Chaput 96add8871e Make RF1 support different slice height.
* Change: In Stratus1, in dpgen_RF1.py, the slice height was hardcoded
    to 50 lambda (sxlib). Now extract the height on the fly from a
    cell.
2016-04-22 22:08:38 +02:00
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 1b7bd9de36 Happy new year 2016! 2016-01-21 00:41:19 +01:00
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.
2015-02-25 22:22:16 +01:00
Jean-Paul Chaput d0d045b55b Starting to implement support for Windows/Cygwin.
* New: In all to CMakeLists.txt, disable the warning about deprecated
   WIN32 under cygwin.
* New: In boostrap, in ccb.py, coriolisEnv.py and builder/Configuration.py
   add recognition in uname for the values returned under Windows/Cygwin.
* New: In Documenation, in UsersGuide.rst add some informations about
   Cygwin and a section for the devel branch.
2014-07-13 13:14:49 +02:00
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.
2014-06-29 14:26:59 +02:00
Jean-Paul Chaput dda3f99fd8 Update documentation for compliance with doxygen 1.8.5.
When upgrading from doxygen 1.5.x to 1.8.5 the way the documentation
is generated has underwent many changes, particularly in the headers.
* Change: In <header.html>, must include the javascripts <jquery.js>
    and <dynsections.js>.
* In <CMakeLists.txt>, as the header is customized, doxygen seems not
    copy some files like the javascripts and some images (open.png,
    closed.png). So we copy them from doxygen installation and make
    the CMakeLists.txt install them. I hope they will not change too
    much in the future.
* In <doxyfile>, disable markdown support as it do not interpret
    correctly the formating we already adopted (with a left margin
    to put command into). Use HTML_EXTRA_STYLESHEET instead of
    HTML_STYLESHEET. Enable the index (DISABLE_INDEX=NO), for the
    top header. Enable dot for inheritance diagram. Set the
    EXAMPLE_PATH=. to include the synthetic hierarchy.
    Correct the tag inclusion (faulty path in some places).
* In <SoC.css>, create style for the new header generated by doxygen.
* In the documentation, move the synthetic hierarchy into a module.
2014-05-13 16:30:41 +02:00
Jean-Paul Chaput f6ab7b87f0 Compliance with g++ 4.8.1, support for devtoolset-2
Details:
* New: in <bootstrap>: add support for devtoolset-2 in ccb. Run the
    cmake commands through 'scl', set shell environment variables
    BOOST_INCLUDEDIR & BOOST_LIBRARYDIR and disable the default
    system path search.
* Change: In various flex scanners add the %nounput to suppress
    compiler warnings.
* Change: Little cleanup for g++ 4.8.1 as it's more strict.
* Change: In various top CMakeLists.txt, suppress extraneous '/'
    after DESTDIR.
2014-03-15 10:47:37 +01:00
Jean-Paul Chaput 34e0edfd61 Cleanup after SVN importation, <ccb> builder script adaptation.
Project hierarchy reorganisation:
* With svn, we were doing a tool by tool checkout, suppressing the
  whole repository hierarchy level.
* The tools were also grouped, inside one repository, into multiple
  projects (<bootstrap>, <vlsisapd>, <coriolis>).
* We do not want to split up each tool into a separate repository,
  given their tight integration (except for vlsisapd).
* We choose to simplify, and consider all tools in a svn repository
  one project. Due to the way Git clone repositories, the directory
  containing the project is now to be seen under "src/".

CMake modifications:
* Now that the <vlsisapd> and <bootstrap> projects are merged into
  coriolis, modificate the top CMakeLists.txt of each tool to uses
  only Coriolis (and bootstrap hard wired).

CCB compile script modifications:
* Uses the new source tree hierarchy, with the project directory
  inserted.
* Remove (comment) all parts relateds to svn managment.
* Git is sufficiently simple so that we do not want to integrate
  command shortcut into the script.

SVN cleanup:
* Remove the obsolete <chamsin> tool, that has become the full fledged
  <chams> project long time ago.
